ct1
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 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).
Function
Monitor
• ffff is displayed when 55.0 A is exceeded.
• If an alarm is output for the Heater Burnout Detection 1 parameter, the No. 1 display will
