output, the alarm output is maintained until
OFF is selected on the heater break or loop
alarm value setting screen or the power
supply is cut.
An alarm is turned ON or OFF according to a
rise or fall of the value of current from a set
value. The hysteresis for the release of alarm
output is fixed to 0.2A.
Initial value: OFF
Setting range: OFF, ON
When ON is set, alarm output is withheld or kept to be on
standby until the current value enters its normal range once
even if the current at the time of applying power is such that
an alarm should be output.
Initial value: OFF
Setting range:OFF, 0.1 – 50.0A
Heater current is detected by CT while control output is ON.
Lower current than a set value of current is taken as
abnormal and an alarm is output.
Initial value: OFF
Setting range: OFF, 0.1 – 50.0A
Heater current is detected by CT while control output is OFF.
Higher current than a set value of current is taken as
abnormal and an alarm is output.
Initial value:
An item intended to be output as an analog signal is selected
