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.
