This parameter measures the heater current from the CT input used for
detecting SSR short-circuits.
This parameter measures and displays the heater current when the heater is
OFF.
HS alarms are not detected if the control output (heating) OFF time is
100 ms or less.
Monitor range Unit
0.0 to 55.0 A
ffff is displayed when 55.0 A is exceeded.
If an HS alarm 1 alarm is output, the HA indicator will light and the No. 1
display for the leakage current 1 monitor will flash.

Heater burnout, HS alarms, and
heater overcurrent detection must be
supported.
Alarm 1 must be assigned.
The HS Alarm parameter must be
set to ON.
Heater burnout, HS alarms, and
heater overcurrent detection must be
supported.
Alarm 1 must be assigned.
The HS Alarm parameter must be
set to ON.
This parameter sets the current for the HS alarm to be output.
An HS alarm is output when the leakage current value exceeds the setting
of this parameter.
When the set value is 50.0, the HS alarm output is turned OFF. When the
set value is 0.0, the HS alarm output is turned ON.
