CAUTION
■
UNUSED INPUT CHANNELS
Set the unused channels to -20 – +20 mA or 0 – 20 mA range. Otherwise, set them as "Unused" with PC Configurator software: R3CON. Unused channels left open with 4 – 20 mA setting are equal to the input lower than -15 %, which sets a data abnormality at the PLC or the host device.
Open circuit with the input range set to ±20 mA means 50 % of the full-scale. An alarm setpoint must be set to a value that does not trip an unwanted alarm.

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.
EXTERNAL VIEW
OUTPUT DATA DESCRIPTIONS
Four alarm setpoints are selectable per each input. Two (2) word (16 bits × 2) data is transmitterd to the PLC or the host device via the R3 network module.
