HB and HS alarms must be supported (two CTs).
The HB ON/OFF parameter must be set to ON.
This parameter measures and displays the heater current value.
• Heater burnout is not detected if the ON time for the control output for heating is 100 ms
or less (30 ms or less if the control period is 0.1 or 0.2 s).
• ffff is displayed when 55.0 A is exceeded.
• If an alarm is output for the Heater Burnout Detection 2 parameter, the No. 1 display will
flash the Heater Current 2 Value Monitor parameter.
