13 Error Handling
KRONOS 20 61
Response: - Error message: Common alarm as warning.
- Error is cleared automatically when speed variance are within warning curve.
Action: - Engine check, particulary the spark plugs.
- Check parameters of warning curve for misfire monitoring.
3047 ErrMisfireEcy 3147 SErrMisfireEcy
Cause: - Speed variance has exceeded the power dependent emergency curve for
monitoring of misfiring.
Response: - Error message: Common alarm.
- Emergency operation in Open-Loop mode
Action: - Engine check, particulary the spark plugs.
- Check parameters of emergency curve for misfire monitoring.
3048 ErrPowerSupplyWarn 3148 SErrPowerSupplyWarn
Cause: - Supply voltage is lower than the minimum voltage for stepper motor control
of the E-LES.
Response: - Error message: Common alarm as warning.
- No control of stepper motor and valve position because of possibility of
stepping errors.
- Error is cleared automatically when supply voltage is above minimum voltage.
Action: - Check supply voltage.
- Check measured value 3600 PowerSupply of the supply voltage.
3061 ErrDigitalOutput1 3161 SErrDigitalOutput1
Cause: - Short circuit or cable break of the E-LES stepper motor wiring harness on
digital output 1.
Response: - Error message: Emergency alarm by fatal error.
- No control of stepper motor and valve position.
Action: - Check cable harness to E-LES stepper motor control for short circuit and cable
break.
3062 ErrDigitalOutput2 3162 SErrDigitalOutput2
Cause: - Short circuit or cable break of the E-LES stepper motor wiring harness on
digital output 2.
Response: - Error message: Emergency alarm by fatal error.
- No control of stepper motor and valve position.
Action: - Check cable harness to E-LES stepper motor control for short circuit and cable
break.
