Diagnostic depth
Enable Condition: Signal LS.Interface.HC.App.CumbustionAirFanMotorState is set to value CumbustionAirFanMotorIsRunning (Combustion air fan motor is active) OR signal LS.CAN.TX.HeaterCoolantPumpState is set to value PumpIsRunning (Coolant pump motor is active) Mature Threshold: Supply voltage > parameter U_MAX_SEVERE (typical value 36V) for a time longer than parameter U_MAX_SEVERE_T_DELAY (typical value 3 seconds) De-mature Criteria: Stable combustion reached after restart of heater: Heating request is switched off (HeaterModeRequest = DeactivateHeater) and on (HeaterModeRequest = NormalMode) and state HEATER RUNNING is reached
- Supply voltage > parameter U_MAX_SEVERE for a time longer than parameter U_MAX_SEVERE_T_DELAY
