4.4 Setting Alarms
Alarm function is available only for the controller with “/AL” or “HBA” option.
Heater disconnection function is available only for the controller with “/HBA” option.
Timer function is available only for the controller with “/AL/EX” or “/HBA/EX” option.
4.4.1 Setting Alarm Type and Hysteresis
The table below shows the alarm codes and alarm actions.
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.

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.
