ALARM SETTING

The following parameters are programmable using the PC

Configurator Software (model: R3CON).

■ALARM TRIP POINT (-15.00 to +115.00 %;

factory set to A1: 80.00, A2: 60.00, A3: 40.00, A4: 20.00)

Four alarm setpoints are selectable per each input.

■ALARM TYPE

(High or Low; factory set to A1: High, A2: High, A3: Low,

A4: Low)

High or Low alarm is selectable for each alarm trip point.

High alarm: An alarm is set when the input signal goes

above the setpoint.

Low alarm: An alarm is set when the input signal goes below

the setpoint.

■DEADBAND (HYSTERESIS)

(0.00 to 100.00 %; factory set to 5.00)

Deadband (deviation between the points where the alarm is

set and reset) is selectable for each alarm trip point.

■ALARM ON DELAY TIME

(0.0 to 99.0 seconds; factory set to 1.0)

The alarm output is set when the preset time elapses after

the input has entered in the alarm range.

This setting is common to all four points.

■POWER ON DELAY TIME

(0.0 to 99.0 sec.; factory set to 5.0)

The alarm output start functioning in the preset time after

• Unused Input Channels

Close across the unused input terminals with a resistor

(5kΩ, 0.5W) as shown below.

INPUT 1

INPUT 2

INPUT 3

INPUT 4

5kΩ (0.5W)

Unused channels left open are equal to the input lower

than -15%, which sets a data abnormality at the PLC or

the host device.

Connecting the resistor means approx. 0% of the full-scale.

An alarm setpoint must be set to a value that does not trip

an unwanted alarm.

Unused channels can be specified and set so on the PC

Configurator Software (model: R3CON) without needing to

connect resistors at the field terminals.

Specifications are subject to change without notice.
