Operation Level Section 5-3
This parameter measures the heater current from the CT input used for
detecting SSR short-circuits.
The heater current is measured and the leakage current 1 monitor is dis-
played.
• 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 measures the heater current from the CT input used for
detecting SSR short-circuits.
This parameter measures and displays the heater current value.
• 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 2 alarm is output, the HA indicator will light and the No. 1
display for the leakage current 2 monitor will flash.
