ALARM SETTING

The following parameters are programmable using the PC

Configurator Software (model: R3CON).

■ALARM TRIP POINT

(-200.0 to +850.0°C or -328 to +1562°F;

factory set to A1: 400.0°C, A2: 300.0°C, A3: 200.0°C,

A4: 100.0°C)

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)

(0.0 to 1000.0°C or 0 to 1800°F; factory set to 10.0°C or

100°F)

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

the power has been turned on.

This setting is common to all four 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 four points.
