HB (Heater Burnout) Alarms, HS (Heater Short) Alarms
Note
(1) Heater burnouts and heater overcurrents are not detected if the control output (heating) ON time is
100 ms or less.
Detection is also sometimes not possible if a contactor is used for the control output.
(2) A heater short is not detected if the control output (heating) OFF time is 100 ms or less.
Detection is also sometimes not possible if a contactor is used for the control output.
