Alarm Function List
Note: The alarms numbered 1 to 10 have no waiting
action, while alarms 11 to 20 have a waiting
action.
The waiting action turns off the PV and deviation
alarms that occur from the start of the control
operation until a stable state is reached.

The output contact closes when the timer setting has passed
since external contact was closed. Then, the output contact
opens immediately when external contact is opened.

Time
The output contact opens when the timer setting has passed
since the contact was closed. Then, the output contact closes
immediately when external contact is opened.
The controller starts measuring the current from
the heater disconnection detector when
100 milliseconds
have passed after turning on the output.
