Heater Burnout Detection 1 (900-TC8, 900-TC16)
Conditions of Use: Heater Burnout (HBA) and Heater Short (HSA) alarms
and heater overcurrent detection must be supported. Alarm 1 must be
assigned. The Heater Burnout Detection parameter must be set to ON. A
single CT must be wired to the controller (single-phase heater operation).
Function: This parameter allows you to configure the current value in amps
(A) at which the electrical Heater Burnout Alarm Output parameter becomes
active (ON).
Table 5.AF
• When the heater current value falls below the configured parameter
value, the Heater Burnout Alarm output goes ON. When the current is
equal to or greater than the value, the alarm is OFF.
• When the configured value is 0.0, the Heater Burnout Alarm is always
OFF. When the configured value is 50.0, the Heater Burnout Alarm is
always ON.
