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 are not detected if the control output (heating) OFF time is 190 ms or
less.
• ffff is displayed when 55.0 A is exceeded.
• If an SSR short-circuit is detected, the HA indicator will light, and the rela-
tive setting level will flash on the No. 1 display.
