lcr1 Leakage Current 1 Monitor<br />

Function<br />

Monitor<br />

See<br />

This parameter measures the heater current from the CT input used for<br />

detecting SSR short-circuits.<br />

The heater current is measured and the leakage current 1 monitor is displayed.<br />

HS alarms are not detected if the control output (heating) OFF time is<br />

100 ms or less.<br />

Monitor range Unit<br />

0.0 to 55.0 A<br />

lcr2 Leakage Current 2 Monitor<br />

Function<br />

Monitor<br />

See<br />

ffff is displayed when 55.0 A is exceeded.<br />

If an HS alarm 1 alarm is output, the HA indicator will light and the No. 1<br />

display for the leakage current 1 monitor will flash.<br />
