Leakage Current 2 Monitor (900-TC8, 900-TC16)
Conditions of Use: Heater Burnout (HBA) and Heater Short (HSA) alarms
and heater overcurrent detection must be supported (two CTs). Alarm 1 must
be assigned. The HS Alarm parameter must be set to ON.
Function: This parameter measures the heater current from two CT inputs
used for detecting a short-circuit condition.
This parameter measures and displays the heater current value.
Note: A Heater Short fault condition is not detected if its duration is 100 ms
or less.
• ffff
