This parameter sets the current value for heater overcurrent alarm outputs.
• A heater overcurrent alarm is output when the heater current exceeds the
value set for this parameter.
• When the set value is 50.0, the heater overcurrent alarm is turned OFF.
When the set value is 0.0, the heater overcurrent alarm is turned ON.

This parameter measures the heater current from the CT input used for
detecting heater burnout.
This parameter measures and displays the heater current value.
• Heater burnouts and heater overcurrent are not detected if the control
output (heating) ON time is 100 ms or less.
• ffff is displayed when 55.0 A is exceeded.
• If a heater burnout detection 2 or heater overcurrent detection 2 alarm is
output, the HA indicator will light and the No. 1 display for the heater cur-
rent 2 value monitor will flash.
