Adjustment Level Section 5-4
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.
• 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.

This parameter sets the current for the HS alarm to be output.
• An HS alarm is output when the leakage current value exceeds the set-
ting 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.
