GENERAL DESCRIPTION

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

manual or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

The Model DLC, Dual Loop Controller, is a full featured, DIN rail mounted,

dual input PID controller. The DLC is designed as a modular building block for

multi-zone process control applications. The controller has two independent

“A” & “B” input channels. Each channel’s input can be configured to accept a

wide range of thermocouple, RTD, 0-10 V, 0/4-20 mA, or resistive signals. Each

channel can also be configured to extract the square root of the input in both

process voltage or process current modes for applications such as flow

measurement using a differential flow sensor.

Do not use the controller to directly command motors, valves, or other

actuators not equipped with safeguards. To do so can be potentially harmful to

persons or equipment in the event of a fault to the controller. An independent

and redundant temperature limit indicator with alarm outputs is strongly

recommended.

Channel B can be assigned as a Remote Setpoint for Channel A. The two

time-proportioning or DC Analog outputs can be programmed to control two

independent processes. The two alarms per channel can be configured for

various alarm modes, or provide a secondary control output for heat/cool

applications.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

The control and alarm outputs are N channel open drain MOSFETs capable

of switching up to 1 Amp DC. For applications requiring larger loads or A/C

loads, several DIN rail mount relays are available.

ALARMS

The DLC’s two solid-state alarms can be configured independently for

absolute high or low acting with balanced or unbalanced hysteresis. They can

also be configured for deviation and band alarm. In these modes, the alarm

trigger values track the setpoint value. Adjustable alarm trip delays can be used

for delaying output response. The alarms can be programmed for Automatic or

Latching operation. Latched alarms must be reset with a serial command. A

standby feature suppresses the alarm during power-up until the temperature

stabilizes outside the alarm region. The outputs can also be manually controlled

with Modbus register or coil commands.

The controller operates in the PID Control Mode for both heating and

cooling, with on-demand auto-tune, that establishes the tuning constants. The

PID tuning constants may be fine-tuned through the serial interface. The

controller employs a unique overshoot suppression feature, which allows the

quickest response without excessive overshoot. The controller can be transferred

to operate in the Manual Mode, providing the operator with direct control of the

output, or the On/Off Control Mode with adjustable hysteresis.

The controller’s high density packaging and DIN rail mounting saves time

and panel space. The controller snaps easily onto standard top hat (T) profile

DIN rails.

SETPOINT CONTROLLER OPTION

The Setpoint Controller option is suitable for time vs. temperature/process

control applications. The controller allows a profile of up to 20 ramp/soak

segments. Profile conformity is assured by using the Error Band Mode and

Error Band parameter. The Profile Cycle Count allows the profile to run

continuously or a fixed number of cycles. Power-on options automatically stop,

abort, start, resume, or pause a running profile.

COMMUNICATIONS

The RS485 serial communications allows the DLC to be multi-dropped, with

Baud rates up to 38400. The CBPRO007 programming cable converts the

RS232 port of a PC to RS485 and is terminated with an RJ11 connector. The

bi-directional capability of the CBPRO007 allows it to be used as a permanent

interface cable as well as a programming cable.

effective. The following EMI suppression devices (or equivalent) are

recommended:

Fair-Rite part number 0443167251 (Red Lion Controls #FCOR0000)

Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls #LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated

and conducted noise (EMI), some type of contact protection network is

normally installed across the load, the contacts or both. The most effective

location is across the load.

a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing

EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the

transistor when the load is switched. One of the most effective ways is to

place a diode across the inductive load. Most Red Lion products with solid

state outputs have internal zener diode protection. However external diode

protection at the load is always a good design practice to limit EMI.

Although the use of a snubber or varistor could be used.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls products are designed with a high degree of

immunity to Electromagnetic Interference (EMI), proper installation and wiring

methods must be followed to ensure compatibility in each application. The type

of the electrical noise, source or coupling method into a unit may be different

for various installations. Cable length, routing, and shield termination are very

important and can mean the difference between a successful or troublesome

installation. Listed are some EMI guidelines for a successful installation in an

industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection

should be made as short as possible. The connection point for the shield

depends somewhat upon the application. Listed below are the recommended

methods of connecting the shield, in order of their effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

Red Lion part numbers: Snubber: SNUB0000

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter. Also, Signal or Control cables within

an enclosure should be routed as far away as possible from contactors,

control relays, transformers, and other noisy components.

Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the

instrument. When a separate input and output common is provided, they

should not be mixed. Therefore a sensor common should NOT be connected

to an output common. This would cause EMI on the sensitive input common,

which could affect the instrument’s operation.

Visit http://www.redlion.net/emi for more information on EMI guidelines,

Safety and CE issues as they relate to Red Lion products.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is

STEP 1 SETTING THE JUMPERS AND DIP SWITCHES

The jumpers are accessible from the bottom of the controller. Needle-nose

pliers are needed to remove the jumpers. They should be set prior to installation.

set using “RLCPRO” or another software program to write to the DLC Modbus

registers (40401-40407). When using the DIP switches to configure the serial

settings, the Modbus mode is limited to “RTU” mode only.

STEP 2 INSTALLING THE CONTROLLER

INSTALLATION

The controller is designed for attachment to standard DIN style top hat (T)

profile mounting rails according to EN50022 -35 x 7.5 and -35 x 15. The

controller should be installed in a location that does not exceed the maximum

operating temperature and provides good air circulation. Placing the controller

near devices that generate excessive heat should be avoided.

T Rail Installation

To install the DLC on a “T” style rail, angle the controller so that the top

groove of the mounting recess is located over the lip of the top rail. Push the

controller toward the rail until it snaps into place. To remove a controller from

the rail, insert a screwdriver into the slot on the bottom of the controller, and

pry upwards until it releases from the rail.

STEP 3 IDENTIFYING THE LEDs - LED FUNCTIONALITY

On power-up, all LEDs are turned on briefly in an alternating pattern to allow visual check of LED functionality.

STEP 4 WIRING THE CONTROLLER

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for each terminal. Also, cabling should conform to appropriate standards of good installation, local codes

and regulations. When wiring the controller, use the numbers on the label to identify the position number with the proper function. Strip the wire, leaving

approximately 1/4" (6 mm) of bare wire exposed. Insert the wire into the terminal, and tighten the screw until the wire is clamped tightly. (Pull wire to verify

tightness.) Each terminal can accept up to one #14 AWG (2.55 mm), two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm) wires.

24 VAC POWER

18 to 36 VDC POWER

CONTROLLER POWER CONNECTIONS

For best results, the power should be relatively “clean” and within the

specified limits. Drawing power from heavily loaded circuits or from circuits

that also power loads that cycle on and off should be avoided. It is recommended

that power supplied to the controller be protected by a fuse or circuit breaker.

RS485 SERIAL CONNECTIONS

There are two modular connectors located on the front for paralleling

communications. The CBPRO007 programming cable converts the RS232 port

of a PC to RS485 and is terminated with an RJ11 connector. The bi-directional

capability of the CBPRO007 allows it to be used as a permanent interface cable

as well as a programming cable.

STEP 7 PROGRAMMING THE PID SETTINGS

Note: The register numbers correspond to (Channel A/Channel B).Channel B PID control is not functional

when the input is assigned as a Remote Setpoint.

The Auto-Tune procedure of the controller sets the Proportional Band, Integral Time, Derivative Time,

Digital Filter, Control Ouput Dampening Time, and Relative Gain (Heat/Cool) values appropriate to the

characteristics of the process.

Proportional Band (40007/40023): Proportional band, entered as percent of full input range, is the band from

the setpoint where the controller adjusts the percent output power based on how close the process value is

to the setpoint. For temperature inputs, the input range is fixed per the entered thermocouple or RTD type.

For process inputs, the input range is the difference between the entered Process Low Scaling Value and the

Process High Scaling Value. The proportional band should be set to obtain the best response to a process

disturbance while minimizing overshoot. A proportional band of 0.0% forces the controller into On/Off

Control with its characteristic cycling at setpoint.

Integral Time (40008/40024): Integral time is defined as the time, in seconds, it takes the output power due to integral action alone to equal

the output power due to proportional action alone during a constant process error. As long as the error exists, integral action repeats the

proportional action each integral time. Integral action shifts the center point position of the proportional band to eliminate error in the

steady state. The higher the integral time, the slower the response. The optimal integral time is best determined during PID Tuning. If time

is set to zero, the previous Integral output power value is maintained. Offset Power can be used to provide Manual Reset. Integral Action

can be disabled by writing a ‘1’ to the Disable Intergral Action register (40044/40052).

Derivative Time (40009/40025): Derivative time, entered as seconds per repeat, is the time that the controller looks ahead at the ramping

error to see what the proportional contribution will be and it matches that value every Derivative time. As long as the ramping error exists,

the Derivative action is repeated by Proportional action every derivative time. Increasing the derivative time helps to stabilize the response,

but too high of a derivative time, coupled with noisy signal processes, may cause the output to fluctuate too greatly, yielding poor control.

Setting the time to zero disables Derivative Action.

Control Mode (40041/40049): In Automatic Mode, the percentage of Output Power is automatically determined by PID or On/Off Control.

In Manual Mode, the percentage of Output Power is entered manually. For more information, see Control Mode Explanations Section.

Output Power (40005/40021): This parameter can only be changed by direct entry in Manual Mode. For more details on this parameter, see

the Control Mode Explanations Section.

Offset Power (Manual Reset) (40010/40026): If the Integral Time is set to zero (Automatic Reset is off), it may be necessary to modify the

output power to eliminate errors in the steady state. The offset power is used to shift the proportional band to compensate for errors in the

steady state. If Integral Action is later invoked, the controller will re-calculate the internal integral value to provide “bumpless” transfer.

Auto-Tune Code (40013/40029): Prior to starting Auto-Tune, this code should be set to achieve the necessary dampening level under PID

Control. When set to zero, it yields the fastest process response with possible overshoot. A setting of 2 yields the slowest response with

the least amount of overshoot. If the Auto-Tune Code is changed, Auto-Tune needs to be reinitiated for the changes to affect the PID

settings. Auto-tune is initiated by writing a ‘1’ to the Auto-Tune start register (40011/40027). The Auto-Tune phase will be shown in

register (40012/40028). For more information, see PID Tuning Explanations Section.

STEP 8 PROGRAMMING THE INPUT SETUP

Input Type (40101/40201): Select the proper input type from the pull down menu. Make sure the input

jumpers are set to match the input signal selection.

Scale (40102/40202): Select either degrees Fahrenheit or Celsius. For mV, resistance, voltage or current types,

this has no effect. If changed, check all temperature related values, as the DLC does not automatically

convert these values.

Resolution (40103/40203): For all temperature and ohms Input Types low (x1) resolution selects whole units

of measure. In these same modes, high (x10) resolution selects tenth of units of measure. For mV mode, low

selects tenths of mV and high selects hundredths of mV. If changed, be sure to check all parameters because

the controller does not automatically convert related parameter values. For voltage or current types, this has

no effect.

Rounding (40104/40204): Rounding selections other than 1 cause the process value to round to the nearest

rounding increment selected. (For example, rounding of 5 causes 122 to round to 120 and 123 to round to

125.) Rounding starts at the least significant digit of the process value. If the signal is inherently jittery, the

process value may be rounded to a value higher than 1. If the range of the signal exceeds the required

resolution (for example, 0-1000 psi, but only 10 psi resolution is required), a rounding increment of 10 will

effectively make the reading more stable.

Digital Filtering (40105/40205): The filter is an adaptive digital filter that discriminates between measurement

noise and actual process changes. If the signal is varying too greatly due to measurement noise, increase the

filter value. If the fastest controller response is needed, decrease the filter value.

Span Correction (40106/40206): This value is the correction slope. A span of 1.0000 applies no correction.

Span only applies to temperature sensor, millivolt, and ohms inputs.

Offset Correction (40107/40207): This value offsets the temperature value by the entered amount. Offset only

applies to temperature sensor, millivolt, and ohms inputs

Channel B Assignment (40198): This is used to configure Channel B to operate as a Remote Setpoint to

Channel A. Channel B PID control is not functional when the input is assigned as a Remote Setpoint.

8

Local/Remote Setpoint Transfer Mode (40199): When cycling from/to Local or Remote Setpoint (register 40046), the response of the controller can be

programmed to act in a variety of ways. The table summarizes the responses for Setpoint transfer options.

Note: In situations where an output bump may occur, the Setpoint ramp function can be used to reduce or eliminate bumping when switching Setpoint modes.

The setpoint ramp feature ramps the setpoint from the old setpoint to the new Setpoint.

Remote Setpoint Ratio Multiplier (40206): This value is used for channel B when it is assigned as a Remote Setpoint Input. The Ratio Multiplier applies to

all input types (0-15).

Remote Setpoint Bias Offset (40207): This value is used for channel B when it is assigned as a Remote Setpoint Input.

Scaling Points (40111-40114/40211-40214): Low and high scaling points are necessary to scale the controller for process voltage and current inputs. Each scaling

point has a coordinate pair of input and process value entries. The process value will be linear between and continue past the entries up to the limit of the input

range. Reverse acting measurement can be accomplished by reversing the Input or Process entries, but not both. (Do not reverse the input wires to change the

action.) To scale a 4-20 mA Input signal to provide process values of 0 to 100.00 (% in hundredths), the Input Low (40113/40213) and Input High (40114/40214)

values would be 4000 and 20000 (0.001 mA resolution), and the Process Low (40111/40211) and Process High (40112/40212) values would be 0 and 10000.

Process Decimal Point (Dec Pt) (40115/40215): The decimal point position is used to enable SFDLC display in desired engineering units for voltage and current

Process values. It is not used internally by the DLC.

STEP 9 PROGRAMMING THE SETPOINTS

Setpoint (40002/40018): Enter the setpoint value. Deviation of Process Value (40001/40017) from

setpoint value can be viewed in the Setpoint Deviation register (40006/40022).

Low Limit (40108/40208); High Limit (40109/40209): The controller has programmable high and low

setpoint limit values to restrict the setting range of the setpoint. Set the limits so that the setpoint value

cannot be set outside the safe operating area of the process.

Ramp Rate (40110/40210): The setpoint ramp rate can reduce sudden shock to the process and reduce

overshoot on startup or after setpoint changes, by ramping the setpoint at a controlled rate. The ramp

rate is 0.1° for input types 0-11, 0.1 Ω for input type 12, 0.01 for input type 13, and 0.1 unit for input

types 14-15 per minute. Writing a ‘0’ disables setpoint ramping. The Disable Setpoint Ramping register

(40042/40050) can also be used to disable ramping. The Setpoint Ramping In-Process register

(40043/40051) will be a ‘1’ during setpoint ramping. While ramping is enabled, the Ramping Setpoint

can be viewed in register (40045/40053). The Ramp Rate for CHB is not functional when it is assigned

as a Remote Setpoint Input.

Once the ramping setpoint reaches the target setpoint, the setpoint ramp rate disengages until the setpoint is changed again. If the ramp value is changed

during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to starting Auto-Tune, the ramping is suspended during Auto-Tune and then

resumed afterward using the present Process value as a starting value. Deviation and band alarms are relative to the target setpoint, not the ramping setpoint. A

slow process may not track the programmed setpoint rate. At power-up, the ramping setpoint is initialized to the starting process value.

Remote/Local Setpoint Select (40046): Channel A setpoint mode can be switched between Local Setpoint operation and Remote Setpoint operation. The

Channel B input must be assigned as a remote setpoint (register 40198).

STEP 10 PROGRAMMING PROFILE SETUP (Optional)

Profile Power Cycle Mode (40321/40421): Upon controller power-on several profile operating modes

exist.

Stop: If the Profile was running when powered down, upon power-up, "Stop" places the profile into the

stop or off mode, regardless of the mode prior to the power-down. The active Setpoint is the setpoint

of the last segment that ran before power-down.

Abort: If the Profile status was running, paused, or in Error Delay when powered down, upon power-up,

"Abort" will place the controller in manual mode at 0% Output Power. The Setpoint and Ramp Rate

are the values they were prior to running the profile. If the Setpoint Controller was 'paused,' they will

be set to the values that they were at power-down.

Start: The Start power cycle mode causes the controller to automatically start the profile at Power-up.

This will occur if the unit was in manual or automatic control mode. During maintenance or at other

times when this action is not desired, the Profile Power Cycle mode should be changed appropriately.

Resume: At Power-up, Resume causes the profile to continue from the point and phase when power was

removed. If the unit was in ramp phase, the ramping setpoint will start ramping from the initial

process value at power-up.

Pause: Upon Power-up, the controller pauses and maintains control at the initial process value (on

power-up), at the phase where the controller was powered down. The user can then determine how to

proceed based on the process that is being controlled.

9

Profile Error Band Mode (Guaranteed Soak) (40322/40422): Profile conformity can be assured by using the profile Error Band Mode and Error Band

parameter. If the process value deviates outside the error band value while a profile is running, the controller enters the delay mode. In the delay mode,

the profile phase timer is held (delayed) until the process value is within the deviation error band value - the Error band hysteresis value. At this time, the

profile continues running unless the process value again deviates. These actions assure that the actual process value conforms to the profile.

Disable Error Band: Error band operation is disabled.

Ramp Phase Only Error Band: The Profile Error Band only applies to the ramp phases of the running profile.

Hold Phase Only Error Band: The Profile Error Band only applies to hold phases of the running profile.

Ramp & Hold Phase Error Band: The Profile Error Band applies to both ramp and hold phases of the running profile.

Profile Error Band (40323/40423): During a hold phase, the profile is paused when the process error is >= the Profile Error Band. The profile will remain

paused until the process error (deviation) is within the Profile Error Band (Error Band-Error Band Hysteresis).

Profile Error Band Hysteresis (40324/40424): Controls the process value at which the profile will come out of an error band delay. If in error band delay,

the profile phase timer is held (delayed) until the process value is within the deviation error band value - the Error band hysteresis value.

Profile End Segment (40325/40425): The Profile End Segment indicates the last segment (i.e., the number of segments to be used in a profile) that is to be

ran in the profile before it stops or re-starts (dependent on Profile Cycle Count/Profile Cycle Count remaining).

Profile Cycle Count (40326/40426): Once a profile is started, it runs the number of cycles programmed in this register and then automatically defaults to

the Profile End Control Mode. If this parameter is changed while the profile is active, the new value (if less than 250) will not take effect until the profile

is stopped and re-started. If the Profile Cycle Count is set to 250 (continuous profile cycling), the change will take affect immediately.

Profile End Control Mode (40327/40427): This parameter sets the type of control action that will be used when the number of profile cycles as programmed

in the Profile Cycle Count parameter has run to completion.

Control Outputs Off : Control is turned off by putting the controller in manual mode at 0% Power. Control can be resumed by changing the Control

Mode (40041/40049) to Automatic.

Automatic: When configured for Automatic the controller will continue controlling at the last setpoint value.

Setpoint Controller Setpoint Segment Registers 1-20 (40601-40620[ChA]/40701-

40720[ChB]): The setpoints for the profile are written in these registers. The values are limited

by the Setpoint Lo and Setpoint Hi limits registers. Register (40601/40701) is the Setpoint for

the 1st segment of the profile.

Setpoint Controller Ramp Rate Segment Registers 1-20 (40621-40640[ChA]/40721-

40740[ChB]): The Ramp Rates for the profile are written in these registers. Register

(40621/40721) is the Ramp Rate for the 1st segment of the profile. A ramp rate of 0 disables

setpoint ramping.

Setpoint Controller Hold Time Segment Registers 1-20 (40641-40660[ChA]/40741-

40760[ChB]): The Hold Times for the profile are written in these registers. Register

(40641/40741) is the Hold Time for the 1st segment of the profile. Segment Hold times of 0

can be used to achieve a ramp with multiple slopes.

STEP 11 MONITORING PROFILE OPERATION (Optional)

Profile Operating Status/Mode (40065/40073)

Stop/Off: The Stop/Off status indicates the profile is dormant or off. A profile can be stopped by setting this register to 0, by allowing a profile to run to

completion, or by removing and re-applying power when the Power Cycle Mode is configured for stop. If the profile was terminated during a ramp

phase, the unit will continue to ramp to the active setpoint.

Abort: Abort is a command action that can be used quickly to stop the profile and turn off the control outputs. The controller is placed into manual mode

at 0% output power. Following the abort command the Profile Operating Status will go to 0 (Stop/Off).

Run/Start: The profile is in the run mode when it is executing. While running, the profile can be stopped (0), paused (3), or advanced to the next phase.

A profile can be started and placed into the Run mode automatically when the controller is powered-up (see Profile Power Cycle Mode). If the profile

was previously stopped, when it is placed in to the Run/Start mode (2), the controller will be put into automatic control (if it was in manual) and start

the profile at the first segment. If the controller was in manual mode prior to starting the profile, the controller will start ramping from the current

process value. If the profile was "paused," it will resume operation. The advancement of the profile can be viewed in the Profile Phase (40066/40074)

and Profile Segment register (40067/40075).

10

Pause: Pause signifies that a profile is active but the time base (Profile Phase Timer) is paused. The pause mode can only be invoked by writing a

3 in the Profile Operating Status register. Pausing a profile during a ramp phase pauses the ramp and the controller maintains control at the

ramping setpoint value (40045/40053) at the instant of the pause action. The use of pause, effectively lengthens the total run time of a profile.

The unit will remain in pause mode until it is placed back in the run mode by writing a 2 (Run/Start) into the Profile Operating Status Register.

Error Delay (Guaranteed Soak): The Error Delay Setting is used only as a status indication. It indicates that a profile is active but the phase timer

or profile advancement has stopped. This is caused by automatic action of the controller when the process deviates more than a specified amount

from the active profile segment. The Error Delay is similar to pause, except the error delay status can only be invoked automatically. See "Profile

Error Band Mode (40322/40422)." Do not write a "4 - Error Delay," to the Profile Operating Status Register. Doing so will instead put the

controller in pause mode (3).

Profile Phase (40066/40074): When the profile is active, this register indicates whether the controller is in a ramp (0) or hold (1) phase.

Profile Segment (40067/40075): Indicates the current active segment while the profile is running. A zero indicates that the profile is stopped or off.

Profile Phase Timer (40068/40076): This register shows the remaining segment phase time in 10ths of minutes. The remaining phase time can be

changed "on the fly" to accelerate or decelerate the phase time. The change in phase time will only affect the running profile and not the stored

parameters. If the phase time is changed during the ramp phase, a new ramp rate will be calculated which will achieve the desired phase time. The

Profile Phase Timer will stop while the unit is paused or during an error delay caused by Profile Error Band operation (guaranteed soak).

Profile Cycle Count Remaining (40069/40077): Indicates the number of profile cycles that are yet to be run. If the Profile Cycle Count register

(40326/40426) is set to 250, the Profile Cycle Count Remaining Register will run continuously, resetting to "250" when reaching "0". This register

value can be changed, however, it will only affect the current run cycle. When the profile is stopped and re-started, the Profile Cycle Count

Remaining Register will be reloaded based on the "Profile Cycle Count (40326/40426)" value.

Advance Profile Phase (40070/40078): Writing a "1" to this register while the profile is running will cause the controller to advance immediately to

the beginning of the next ramp or hold phase. Using the advance operation shortens the total run time of the profile. If the profile is "paused," the

profile will advance but the profile will remain paused. The Profile can also be advanced while in the error delay mode.

STEP 12 PROGRAMMING THE OUTPUTS

Cycle Time (40116/40216): The cycle time, entered in seconds, is the combined time of an on and off

cycle of a time proportioning control output OP1/OP2. With time proportional output, the percentage

of control power is converted into output on time of the cycle time value. (If the controller calculates

that 65% power is required and has a cycle time of 10 seconds, the output will be on for 6.5 seconds

and off for 3.5 seconds.) For best control, a cycle time equal to one-tenth of the process time constant,

or less, is recommended. When using the DC Analog output signal for control, a setting of zero will

keep output OP1 off. The status of OP1 can be read through registers 40014/40030.

Control Action (40117/40217): This determines the control action for the PID loop. Programmed for

direct action (cooling), the DLC output power will increase if the Process value is above the Setpoint

value. Programmed for reverse action (heating), the output power decreases when the Process Value is

above the Setpoint Value. For heat and cool applications, this is typically set to reverse. This allows

OP1 to be used for heating, and AL2/OP2 to be used for cooling.

Power Low Limit (40118/40218); High Limit (40119/40219): These parameters may be used to limit controller power due to process disturbances

or setpoint changes. Enter the safe output power limits for the process. If Alarm 2 is selected for cooling, the range is from -100 to +100%. At 0%,

both OP1 and OP2 are off; at 100%, OP1 is on; and at -100%, OP2 is on. When the controller is in Manual Control Mode, these limits do not apply.

Sensor Fail Power Preset (40120/40220): This parameter sets the power level for the control outputs in the event of a sensor failure or extreme

overdriven/underdriven input. If Alarm 2 is not selected for cooling, the range is from 0% (OP1 output full off) to 100% (OP1 output full on). If

AL2 is selected for cooling, the range is from -100 to +100%. At 0%, both OP1 and OP2 are off; at 100%, OP1 is on; and at -100%, OP2 is on. The

alarm outputs are upscale drive with an open sensor, and downscale drive with a shorted sensor (RTD only), independent of this setting. Manual

Control overrides the sensor fail preset.

Dampening Time (40121/40221): The dampening time, entered as a time constant in seconds, dampens (filters) the calculated output power.

Increasing the value increases the dampening effect. Generally, dampening times in the range of one-twentieth to one-fiftieth of the controller’s

integral time (or process time constant) is effective. Dampening times longer than these may cause controller instability due to the added lag effect.

On/Off Control Hysteresis (40122/40222): The controller can be placed in the On/Off Control Mode by setting the Proportional Band to 0.0%. The

On/Off Control Hysteresis (balanced around the setpoint) eliminates output chatter. In heat/cool applications, the control hysteresis value affects

both Output OP1 and Output OP2 control. It is suggested to set the hysteresis band to 2 (Factory Setting) prior to starting Auto-Tune. After Auto-

Tune, the hysteresis band has no effect on PID Control. On/Off Control Hysteresis is illustrated in the the On/Off Control Mode section.

11

STEP 13 PROGRAMMING THE ALARMS

Alarm 1 and 2: The controller is equipped with two alarms for each channel. The status of these alarms

can be read through AL1 registers 40015/40031 and AL2 registers 40016/40032.

Action (40131/40231), (40136/40236): Select the action for the alarms. See Alarm Action Figures for a

visual explanation.

Manual: In Manual mode, the alarms are forced on and off by writing ‘0’ or ‘1’ to the appropriate

alarm output register. In this mode, the alarms will not respond to Alarm and Hysteresis Values.

Absolute HI (balanced or unbalanced hysteresis): The alarm energizes when the Process Value exceeds

the alarm.

Absolute LO (balanced or unbalanced hysteresis): The alarm energizes when the Process Value falls

below the alarm.

Deviation HI, Deviation LO, Band Acting: In these actions, Alarm 1 and 2 value tracks the Setpoint

value.

Cooling (OP2): For heat/cool applications, select Cool for Alarm 2. The controller then utilizes the

Alarm 2 output as the Cooling Output (OP2). If cooling is selected, the remaining Alarm 2

parameters are not available.

Trigger Points: Trigger points are the Process Values where the alarm state changes. Their values cannot be entered directly, but are shown as a reference in the

SFDLC software. The alarm value, hysteresis value, and setpoint alarm type determine the trigger points. With Deviation or Band actions, the alarm value and

setpoint value are combined to determine the trigger points. Trigger points must not be greater than +32000 or less than -32000. If these limits are exceeded,

the alarm may not function properly.

Reset (40132/40232), (40137/40237): The alarms can be programmed for Automatic or Latched. In Automatic mode, an energized alarm turns off automatically

once the Process Value leaves the alarm region. In Latched mode, an energized alarm requires a manual reset. This is done by writing ‘0’ to the appropriate

output status register. After writing ‘0’, the Automatic or Latched alarm will not turn on again until after the Process Value first returns to the alarm off region.

Only alarms configured for Manual action can be energized by writing a ‘1’ to its’ alarm output status register.

On Delay (40135/40235), (40140/40240): The time, in seconds, required for the Process Value to be in the alarm region before the alarm will activate. It is used

to allow temporary or short excursions into the alarm region without tripping the alarm.

Enable Standby Delay (40133/40233), (40138/40238): Standby prevents nuisance (typically low level) alarms after a power up or setpoint change. After

powering up the controller or changing the setpoint, the process must leave the alarm region. Once this has occurred, the standby is disabled and the alarm

responds normally until the next controller power up or setpoint change.

STEP 14 PROGRAMMING THE COOLING

To enable Cooling in Heat/Cool applications, the Alarm 2 Action must first be set for Cooling. When

set to cooling, the output no longer operates as an alarm but operates as an independent cooling output.

The OP2 terminals are the same as AL2. Cooling output power ranges from -100% (full cooling) to 0%

(no cooling, unless a heat/cool deadband overlap is used). The Power Limits in the Output category also

limits the cooling power.

Cycle Time (40141/40241): This cycle time functions like the OP1 Output Cycle Time but allows

independent cycle time for cooling. A setting of zero will keep output OP2 off. The status of OP2 can

be read through registers (40016/40032).

Relative Gain (40142/40242): This defines the gain of the cooling relative to the heating. It is generally

set to balance the effects of cooling to that of heating. This is illustrated in the Heat/Cool Relative Gain

Figures. A value of 0.0 places the cooling output into On/Off Control. This may be done independent

of the OP1 Output PID or On/Off Control Modes.

Deadband (40143/40243): This defines the area in which both heating and cooling are active (negative

value) or the deadband area between the bands (positive value). If a heat/cool overlap is specified, the

percent output power is the sum of the heat power (OP1) and the cool power (OP2). If Relative Gain

is zero, the cooling output operates in the On/Off Control Mode, with the Deadband value becoming

the cooling output hysteresis (positive value only). This is illustrated in the On/Off Control Mode

section. For most applications, set this parameter to 0.0 prior to starting Auto-Tune. After the

completion of Auto-Tune, this parameter may be changed.

STEP 15 PROGRAMMING THE ANALOG OUTPUT (Optional)

Note: The register numbers correspond to (Analog Output 1/Output 2).

Assignment (40301/40309): This setting selects the value that the Analog Output will retransmit, or track.

The Analog output can be assigned for the following:

Direct Entry Value 2

Mode (40302/40310): Select the type of output and range. The Analog output jumpers must be set to match the

output type and range selected. The Analog output can be calibrated to provide up to 5% of over range operation.

Output Scaling Values: The Scaling Low value (40303/40311) corresponds to 0 V, 0 mA or 4 mA, depending on

the range selected. The Scaling High value (40304/40312) corresponds to 10 V or 20 mA depending on the range

selected. An inverse acting output can be achieved by reversing the Scaling Low and Scaling High points.

Deadband (40305/40313): The output power change must be greater than the deadband value in order for the

Analog output to update. This only applies when the Analog Output is assigned to Output Power. This setting

can be used to reduce actuator activity.

Update Time (40306/40314): To reduce excess valve actuator or pen recorder activity, the update time of the

analog output can be set in seconds. A value of zero seconds results in an update time of 0.1 second.

Direct Entry Value (40307/40315): If the analog output is programmed for Direct Entry, it retransmits this value.

This value may be controlled by the host.

Filter (40308-40316): Entering a 1 will apply averaging when the Update Time >=1.

STEP 16 PROGRAMMING THE DLC COMMS PORT

Note: If the software selectable communication settings are changed and then a download is performed, the

controller will immediately respond to the new settings. Any further attempts to communicate to the controller

must target the new address, with the new settings.

Parity (40403): odd, even, or none

Transmit Delay (40406): Programmable from 2-250 milliseconds.

The Transmit Delay is the time the DLC waits to respond to a serial

command, UNLESS the values in the table are larger.

Note: Changing the above parameters by writing to their registers

directly will not update the DLC until Load Serial Settings register

40407 is a ‘1’. After a write, this register will return to ‘0’.

configure the serial settings, the Modbus communications mode will be RTU only. There is also a "Default Serial

Settings" switch to quickly configure the DLC for use with the "RLCPRO" Programming Software.

Software Selectable Serial Settings: Setting all of the DIP switches to the "off" position and having the "Default

Serial Setting" terminal un-connected, enables Software Selectable Serial settings. When leaving the factory the

Software Selectable serial settings are set to the Serial Communication Defaults. Software Selectable Serial

Settings allows set-up of all serial settings including the choice of RTU or ACSII communications modes and the

number of data bits. If the Software Selectable Serial Settings are changed, the load serial register must be used

or power to the DLC must be removed and re-applied in order for the settings to take effect. The use of RLCPRO

Programming software or another software program supporting Modbus protocol is required to write to the DLC

serial settings registers (40401-40407).

14

Default Serial Settings: The DLC serial port can be temporarily set to the factory defaults by setting the Default serial communications DIP switch to

the “up” position OR by placing a jumper from the “Default Serial Setting” terminal 7 (TBB) to Output common terminal 4 (TBA). Both of these

have precedence over the DIP switch serial settings and the software selectable serial settings. Once the serial default DIP switch is set to the “off”

position or the jumper is removed, the DLC serial settings will immediately change as programmed by the DIP switches or the software selectable

serial settings if all of the DIP switches are in the “off” position. The Default Serial Settings are NOT loaded into the software selectable serial

registers when the serial default setting switch/terminal is active, they must be explicitly changed.

Serial Communication Defaults: 9600 baud, 1 start bit, no Parity, 1 stop bit, address 247, and RTU mode.

Communications Diagnostics: The Communications Diagnostics function (MODBUS Function Code 08) can be used to troubleshoot systems that are

experiencing communication errors. Press the Read button to retrieve the diagnostics information. The Commands Received and the Commands

Processed values are automatically reset when the values are read, at each controller power-up, and when the Commands Received reaches 65536.

Commands Received: The total number of messages received that started with the controller’s own address since the last reset or power up.

Commands Processed: The number of “good” messages received. A “good” message is considered one that contained the correct unit address,

parity, and checksum (CRC or LRC).

STEP 17 PC PORT CONFIGURATION

Go to the SETTINGS pull-down menu, and select PC PORT SETTINGS.

The Communications Settings window allows you to set up the software properly to perform a download.

Connection: Select the computer port (COMM 1-4) that the DLC is connected to.

Note: The following settings must match the DLC. If you do not know or cannot recall the DLC settings, they can

be temporarily set to factory defaults. Simply jumper the Default Serial Setting terminal 7 to Input Common

terminal 4 or put the Default Serial Settings DIP switch in the “UP” position. The serial settings will default

to RTU mode, 9600 baud, 8 data bits, no parity, with an address of 247.

Protocol: RTU or ASCII

STEP 19 SCRATCH PAD MEMORY

The Scratch Pad category can be used to read or write to the Scratch Pad memory locations (41101-

41116). The Scratch Pad locations can be used to store user information.

Data Format: Allows registers to be viewed in decimal or hexadecimal format.

Upload: The Upload button causes SFDLC software to read the Scratch Pad registers from the controller.

Download: The Download button causes SFDLC software to write to the Scratch Pad registers in the

controller.

Note: Downloading new values to the controller Scratch Pad locations overwrites the information that is

currently stored in those registers.

Defaults: For this category, there are no controller factory defaults. The defaults for this category are only

SFDLC software basic default values.

STEP 20 VIEW REGISTERS

The View Registers category can be used as a method of diagnostics. Use the DLC Register Table as a

reference of register assignments and data.

First Register: This specifies the first register to be read in a block.

# of Registers: This is the length of the block to be read. The controller supports block read and write

commands up to 32 registers in length. The SFDLC software only allows 16 to be read in a block.

Data Format: Allows registers to be viewed in decimal or hexadecimal format.

Read: Clicking the Read button causes SFDLC software to read the selected registers from the controller.

Write: Clicking the Write button causes SFDLC software to write the selected registers to the controller.

Note: The Write button overwrites the existing register values, and may change the module setup and

operation.

Defaults: For this category, there are no controller factory defaults. By clicking Defaults, the present

entries from the other SFDLC software category screens will be displayed.

STEP 21 CALIBRATION

The DLC is fully calibrated from the factory. Recalibration is recommended every two years. Each channel is calibrated separately. All calibration settings

are stored in the non-volatile memory. Calibration may be performed by using SFDLC software or MODBUS commands. When using SFDLC for calibration,

connect the signal or measuring source to the proper DLC terminals, verify the input or output jumper positions, select the type of calibration to be performed,

and click the Calibrate button. Follow the calibration procedures in the software.

Note: Allow the DLC to warm up for 30 minutes minimum and follow the manufacturer’s warm-up recommendations for the calibration source.

INPUT CALIBRATION

When calibrating the input, the millivolt calibration must be performed first. All other input types use the

millivolt points. Each input range (non-thermocouple) also has its own internal references that are recalled

when the range is selected. Non-used types need not be calibrated.

Calibration Type: This specifies the type of calibration to be performed.

Millivolt: Millivolt calibration requires a precision voltage source with an accuracy of 0.03% or better.

It is used for thermocouple inputs and as a basis for all other input calibration types.

RTD: RTD calibration requires a 0.1% (or better) precision 277.0 ohm resistor.

Process Voltage: Process calibration requires a precision signal source with an accuracy of 0.03% (or

better) that is capable of generating 10.00 V.

Process Current: Process current calibration requires a precision signal source with an accuracy of

0.03% (or better) that is capable of generating 20.00 mA.

Cold Junction: Cold Junction calibration requires a thermocouple of known accuracy of types T, E, J, K, C or N only and a calibrated external reference

thermocouple probe.

TC Type: This selects the type of TC that is being used to calibrate the cold junction.

Scale: This selects the scale in which the Thermometer temperature is entered and the controller temperature is displayed.

Thermometer: Enter the reference thermometer temperature here.

DLC: This displays the DLC process temperature value after a cold junction calibration is completed to verify the accuracy.

Calibrate: The Calibrate button initiates the calibration process after the appropriate settings are selected.

16

ANALOG OUTPUT CALIBRATION

Calibration Type: This specifies the Analog Output point to be calibrated.

Volts: Analog Output Voltage calibration requires a precision meter with an accuracy of 0.05% (or better)

that is capable of measuring 10.00 V.

mA: Analog Output Current calibration requires a precision meter with an accuracy of 0.05% (or better)

that is capable of measuring 20.00 mA.

Meter Value: After pressing the Calibrate button, this shows the value the DLC is outputting. Measure the

actual output with an external meter and enter that value here. Press the Calibrate button again and follow

the prompts.

Calibrate: The Calibrate button initiates the calibration process after the appropriate settings are selected.

APPLICATION

A plastic extrusion company was building a four-zone extruder, and wanted a centrally located,

multi-zone interface. The interface needed to display the temperature and setpoint values, as well as

the screw RPM and barrel pressure. The customer provided a speed proportional 0-10 Volt signal

from a motor drive, and installed a 4-20 mA output pressure sensor in the extruder barrel. Each of

the four heat/cool zones were equipped with a thermocouple.

Three DLC-Dual Loop Controllers, with a G3 HMI, allowed the customer to build his own control

system. Only three DLCs were required; two were needed to control the four temperature zones, and

one was needed to monitor the two process signals.

CONTROL MODE EXPLANATIONS

MANUAL CONTROL MODE

MODE TRANSFER

In Manual Control Mode, the controller operates as an open loop system

(does not use the setpoint and process feedback). The user enters a percentage

of power through the Output Power register (40005/40021) to control the heat

(reverse) or cool (direct) for Output OP1. When Alarm 2 is configured for

Cooling (OP2), Manual operation provides 0 to 100% power to OP1 (heating)

and -100 to 0% power to OP2 (Cooling). The Low and High Power limits are

ignored when the controller is in Manual.

When transferring the controller mode from or to Automatic, the controlling

outputs remain constant, exercising true bumpless transfer. When transferring

from Manual to Automatic, the power initially remains steady, but Integral

Action corrects (if necessary) the closed loop power demand at a rate

proportional to the Integral Time. The Control Mode can be changed through

the Control Mode register (40041/40049).

For time proportional outputs, the output power is converted into output On

time using the Cycle Time. For example, with a four second cycle time and 75%

power, the output will be on (4 × 0.75) for three seconds and off for one second.

For Analog Outputs (0-10 VDC or 0/4-20 mA), the percent output power is

converted into a linear value according to the Percent Low and High scaling set

for the analog output. For example, with 0 VDC (scaled 0.0%) to 10 VDC

(scaled 100%) and 75% power, the analog output will be 7.5 VDC.

AUTOMATIC CONTROL MODE

In Automatic Control Mode, the percentage of output power is automatically

determined by PID or On/Off calculations based on the setpoint and process

feedback. For this reason, PID Control and On/Off Control always imply

Automatic Control Mode.

17

ON/OFF CONTROL - HEAT/COOL OUTPUT FIGURES

ON/OFF CONTROL

The controller operates in On/Off Control when the Proportional Band is set

to 0.0%. In this control, the process will constantly oscillate around the setpoint

value. The On/Off Control Hysteresis (balanced around the setpoint) can be

used to eliminate output chatter. Output OP1 Control Action can be set to

reverse for heating (output on when below the setpoint) or direct for cooling

(output on when above the setpoint) applications.

TYPICAL PID RESPONSE CURVE

PID CONTROL

In PID Control, the controller processes the input and then calculates a

control output power value by use of a modified Proportional Band, Integral

Time, and Derivative Time control algorithm. The system is controlled with the

new output power value to keep the process at the setpoint. The Control Action

for PID Control can be set to reverse for heating (output on when below the

setpoint) or direct for cooling (output on when above the setpoint) applications.

For heat and cool systems, the heat (OP1) and cool (OP2) outputs can be used

together in the PID Control. The PID parameters can be Auto-Tune or Manual

REMOTE SETPOINT

Channel B can operate as a Remote Setpoint Input to Channel A. Channel B

PID control is not functional when the input is assigned as a Remote Setpoint.

This mode of operation enables Cascade control (external), Ratio control, and

Temperature Setpoint Slave control, among others.

The Ratio Multiplier and Bias Offset parameters offer on-line scaling of the

Remote Setpoint to adjust control ratios or biases among related processes.

The Remote Setpoint is restricted to the setpoint low and high limit values for

channel B. These parameters may be used to limit the range of the Remote

Setpoint to a safe or more stable control range. For Remote Setpoint signal

sources that change wildly or are too sensitive to process upsets, the CHA

Setpoint Ramp Rate parameter (40110) can be used to ramp (rate limit) the

Remote Setpoint reading. This can subsequently reduce the fluctuations of the

secondary control loop.

The Remote Setpoint value used internally by the controller is:

Remote Setpoint = (Scaled CHB Input * Remote Setpoint Ratio Multiplier)

PID TUNING EXPLANATIONS

AUTO-TUNE

AUTO-TUNE CODE FIGURE

INPUT

Auto-Tune is a user-initiated function where the controller automatically determines the

Proportional Band, Integral Time, Derivative Time, Digital Filter, Control Ouput Dampening

Time, and Relative Gain (Heat/Cool) values based upon the process characteristics. The

Auto-Tune operation cycles the controlling output(s) at a control point three-quarters of the

distance between the present process value and the setpoint. The nature of these oscillations

determines the settings for the controller’s parameters.

SP

2

Prior to initiating Auto-Tune, it is important that the controller and system be first tested.

(This can be accomplished in On/Off Control or Manual Control Mode.) If there is a wiring,

system or controller problem, Auto-Tune may give incorrect tuning or may never finish.

Auto-Tune may be initiated at start-up, from setpoint or at any other process point. However,

insure normal process conditions (example: minimize unusual external load disturbances) as

they will have an effect on the PID calculations. Auto-Tune cannot be initiated while running

a profile.

The controller will oscillate the controlling output(s) for four cycles. The cycling

phase can be monitored from the Auto-Tune Phase Register (Channel A 40012/

Channel B 40028). The time to complete the Auto-Tune cycles is process dependent.

The controller should automatically stop Auto-Tune and store the calculated values

when the four cycles are complete. If the controller remains in Auto-Tune unusually

long, there may be a process problem. Auto-Tune may be stopped by entering ‘0’ in

In some unusual cases, the Auto-Tune function may not yield acceptable

applications, Manual Tuning is an alternative.

In some applications, it may be necessary to fine tune the Auto-Tune

will not stabilize and starts to oscillate, set the Proportional Band two times

higher and go back to Step 5.

7. If the process is stable, decrease Proportional Band setting by two times and

change the setpoint value a small amount to excite the process. Continue with

this step until the process oscillates in a continuous nature.

MANUAL TUNING

A chart recorder or data logging device is necessary to measure the time

between process cycles. This procedure is an alternative to the controller’s

Auto-Tune function. It will not provide acceptable results if system problems

exist. This procedure should be performed by directly accessing the controller’s

registers. The register numbers correspond to (Channel A/Channel B).

SUPPORTED EXCEPTION CODES

Cold Junction Calibration *

01: Illegal Function

Cold Junction calibration requires a thermocouple of known accuracy of

types T, E, J, K, C or N only and a calibrated external reference thermocouple

probe.

Issued whenever the requested function is not implemented in the controller.

02: Illegal Data Address

1. Connect the thermocouple probe source to the proper DLC terminals.

2. Enter the connected thermocouple type into register 40101 (Ch A) or 40201

(Ch B).

Issued whenever an attempt is made to access a single register or coil that

does not exist (outside the implemented space) or to access a block of registers

or coils that falls completely outside the implemented space.

3. Enter the scale (F or C) that matches the thermometer and the controller

temperature, preferrably °C into register 40102 (Ch A) or 40202 (Ch B).

4. Enter 1 for high resolution into register 40103 (Ch A) or 40203 (Ch B).

5. Place an external reference thermometer probe at the end of the DLC probe.

The two probes should be shielded from air movement and allowed sufficient

time to equalize in temperature. (As an alternative, the DLC probe may be

placed in a calibration bath of known temperature.)

6. To open calibration mode, enter 48 into register 40501.

7. To start CJ calibration, enter 10 (Ch A) or 110 (Ch B) into register 40501.

8. Read the Process Value register 40001 (Ch A) or 40017 (Ch B).

9. Subtract the external reference reading from the Process Value register

reading. Adjust the results to tenths position, drop decimal point, and

maintain the results sign. (If the difference is -2 degrees, then adjust to -2.0

and remove decimal point yielding a value of -20.)

10. Add the value from step 9 (maintain the sign) to the value existing in register

40502.

11. If necessary, continue to adjust the register 40502 value until the Process

Value register 40001 (Ch A) or 40017 (Ch B) matches the external reference

reading.

12. To exit CJ calibration, enter 11 (Ch A) or 111 (Ch B) into register 40501.

13. To save the calibration results and close calibration mode, enter 0 into

register 40501.

03: Illegal Data Value

Issued when an attempt is made to read or write more registers or coils than

the controller can handle in one request.

07: Negative Acknowledge

Issued when a write to coil or register is attempted with an invalid string

length.

CHECKSUM ERRORS

1. Calibration checksum covers the area that contains calibration values for all

ranges. When a calibration checksum error occurs, coil 1 becomes a “1”.

2. Parameter checksum covers the area that contains the stored Holding register

settings. When this checksum error occurs, coil 2 becomes a “1”.

3. Integral and Offset/Manual Power checksum covers the area that contains the

stored Integral register settings. When this checksum error occurs, coil 3

becomes a “1”.

4. Setpoint Controller Segment Memory checksum covers the memory area that

contains the profile segments for channel A and B. When this checksum error

occurs, coil 29 becomes a "1".

5. Setpoint Controller Status Memory checksum covers the memory area that

contains the profile operating status. When this checksum error occurs, coil

30 becomes a "1" and aborts the profile putting channel in manual control at

0% power.

6. All LEDs except PWR/COMMS will flash as long as one of the errors exist.

7. The control and alarm outputs are disabled as long as one of the errors exist.

8. These errors can be cleared or activated manually by writing to the

appropriate coil. (This does not correct the reason for the error. It may be

necessary to reconfigure or calibrate.)

RTD Calibration *

1. Connect a precision 277.0 ohm resistor, and a short, to terminals 1 & 2 (Ch

B) or 4 & 5 (Ch A). During the complete procedure, short terminals 2 & 3

(Ch B) or 5 & 6 (Ch A).

9. The checksums are verified at power up.

2. Verify the input jumper is in the RTD position.

3. Enter 12 (ohms mode) into register 40101 (Ch A) or 40201 (Ch B).

4. To open calibration mode, enter 48 into register 40501.

5. To start RTD calibration, enter 20 (Ch A) or 120 (Ch B) into register 40501.

6. Leave 0 ohms (short) on terminals 1 & 2 (Ch B) or 4 & 5 (Ch A) for 10

seconds.

7. To store 0 ohm results, enter 21 (Ch A) or 121 (Ch B) into register 40501.

8. Apply 277 ohms by removing the short from terminal 1 & 2 (Ch B) or 4 & 5

(Ch A) for 10 seconds.

CALIBRATION USING MODBUS COMMANDS

The DLC is fully calibrated from the factory. Recalibration is recommended

every two years. Each channel is calibrated separately. All calibration settings

are stored in the non-volatile memory. The DLC may be calibrated using

MODBUS. However, the preferred method of calibrating the controller is

through the SFDLC software.

When calibrating the input, a successful millivolt calibration must be

performed first. All other input types use the millivolt points. Each input range

(non-thermocouple) also has its own internal references that are recalled when

the range is selected. Non-used types need not be calibrated.

9. To store 277 ohm results, enter 22 (Ch A) or 122 (Ch B) into register 40501.

10. To save the calibration results and close calibration mode, enter 0 into

register 40501.

Each of the procedures below show the calibration steps/register numbers for

both channels A & B, however, only one channel can be calibrated at a time.

Note: Allow the DLC to warm up for 30 minutes minimum and follow the

manufacturer’s warm-up recommendations for the calibration or measuring

source.

Process Voltage Calibration *

Process calibration requires a precision signal source with an accuracy of

0.03% (or better) that is capable of generating 10.00 V.
