DATA SHEET
FUZZY CONTROLLER X (48
)48mm)
PYX4
The PYX is a state-the-art temperature controller offering
enhanced control through the use of fuzzy logic. By em-
ploying fuzzy logic the PYX virtually eliminates system
overshoot and effectively supresses fluctuation of the
process variable due to external disturbances. Fuzzy logic
control is the technology of tomorrow offered today.
This controller features universal input circuitry and can
accept signals from all thermocouple types, RTD's, and
current/voltage sources. As well, the PYX-4 gives you the
flexibility of choosing such available features as RS-485
communications, analog retransmission, dual output, heater
break alarm, and loop break alarm, to name a few. The
PYX-4 is the world's first 1/16 DIN fuzzy logic controller
featuring high performance/cost ratio.
FEATURES
1. Industry-first incorporation of fuzzy control in 48 mm-
square controller
6. UL, C-UL approval
An improved response characteristic of controller is
ensured thanks to the fuzzy control exercised while
detecting an overshoot or a difference from the set
temperature value due to a large disturbance.
(Time taken for returning to the set value can be shortened
and temperature variation width can be narrowed.)
2. Universal input
This means that a signal controller can respond to 11 kinds
of thermocouples, resistance bulbs and voltage/current
inputs.

GENERAL SPECIFICATIONS
• Size (H x W x D): 48 x 48 x 115mm
• Kinds of input:
Full multi-input type
•Thermocouple (TC):
J, K, R, B, T, E, S, N, U, WRe5-26, PL-II
• Platinum resistance bulb (RTD):
Pt 100Ω
3. Communication function comprised despite small size
(option)
Because the general-purpose interface (RS-485) is
mountable, a centralized monitoring/setting system aided
by a personal computer can readily be configured. Upon
building up a system, the size of this controller as small
as 48 mm square is helpful for saving on the equipment
installation area.
• Voltage/Current: DC1 to 5V/0 to 5V/4 to 20mA
• Input accuracy: ±0.5% of full scale, ±1 digit (±1°C at
thermocouple)
B (TC) 0 to 500°C : ±5% of full
}
R (TC) 0 to 400°C : ±1% of scale
The communication protocol conforms either the Fuji

Modbus or CC-data line protocol.
Dual control of heating and cooling operations are
allowed
• Programmable alarms: 2 points max.

(with heater current message-function)
(5) Ramp/soak function
• Heater break alarm: 1 point
• Ramp/soak function: 4 ramp/soak-pair
patterns
• Auxiliary digital input: 1 point
• Remote SV input: 1 point

■ FUNCTIONS
(4) Auto-tuning
(1) Fuzzy feedback control
PID parameters are automatically set by controller's
measurement and operation.
Fuzzy feedback control expresses the basic actions of
PID control in fuzzy rules and has a nonlinear characteristic
in order to straighten out the problem inherent to PID
control (i.e., overshoot occurs when improving response
or instability arises due to a change in system even when
optimum PID parameters are assigned).

• Comparison of controllability
Each result of fuzzy control and PID control is shown
below.
It is understandable that the overshoot due to a change
of set value has been suppressed in fuzzy control.

(2) Ramp soak function (option)

Function to automatically change the set point value with
elapsing of time, in accordance with the preset pattern,
as shown below. This device allows maximum of 4 ramp
soak programs.
This first ramp starts at the value measured immediately
before the program is executed (PV).
PID control
ON-OFF action
Remarks: (1) Once auto-tuning has been made, PID parameter values
are retained despite power-off operation. Therefore, auto-
tuning need not be repeated for the subsequent operations.
(2) During auto-tuning, control output corresponds to ON/OFF
action. This may cause PV to change widely depending
on process. If such a change is unallowable, auto-tuning
should not be used.

etc.

• Example of connection of heater break alarm
The controller incorporates both the heating output and
the cooling output for setting "cooling control cycle", "cooling
proportional band" and "dead band or overlap band".

Remarks:
(1) PID auto-tuning is carried out only on the heating side. During auto-
tuning, output on the cooling side remains turned off. After auto-
tuning, both heating and cooling operations are performed according
to the same PID values.
(2) ID set value is the same between heating and cooling sides.
Individual setting cannot be accepted.
(7) Heater break alarm (option)
• Use the current transformer (CT) specified by Fuji.
• Heater break is detected only when single-phase heater
is used.
• Heater break alarm is not available when controlling the
heater by thyristor phase-angle control method.
• [alarm detection point] and [Heater current] are registered
using of front key.

CAUTION OF SAFETY
First of all, read this "Caution on Safety" carefully, and then use the instrument in the correct way.
The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those
safety precautions are classilied in 2 ranks, WARNING and CAUTION.
The following shows the meaning of WARNING and CAUTION.
Wrong handling may cause a dangerous situation in which there is 2 possibility
of death or heavy injury.
WARNING
Wrong handling may cause a dangerous situation in which there is a possibility
of injury or physical damage.
CAUTION
WARNING
For the safe operation of the controller, where the temperature probe is to be installed into an environment where voltages
exceed 50 VDC, it is essential that reinforced isolation or basic isolation and earth is maintained between all connections to the
rear of the temperature controller, and that supplementary isolation is required for the alarm outputs.
The outputs from the controller are all less than 50 VDC.
When wiring the power supply terminal, use vinyl insulated 600 volt cable or equivalent. A switch breaking both poles of the
mains supply should be installed together with a fuse with a rating of 250volt 1Amp. The fuse should be installed between the
mains switch and the controller.
The level of insulation provided by the temperature controller is;
MAINS=BASIC
HEATER=BASIC
INPUTS=BASIC
Prior to operation of the installed system the wiring should be checked to ensure that the required levels of insulation have been
provided.
