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 8 points.

■POWER ON DELAY TIME

(0.0 to 99.0 seconds; factory set to 5.0)

The alarm output start functioning in the preset time after

the power has been turned on.

This setting is common to all 8 points.

■ALARM HOLD TIME

(0.0 to 99.0 seconds; factory set to 1.0)

The alarm output is held for the preset time even if it is

reset in shorter time.

This setting is common to all 8 points.
