13 Error Handling
60 KRONOS 20
- Check manifold temperature sensor and replace if required.
- Check tolerance values for manifold temperature sensor.
3019 ErrMeasuredPower 3119 SErrMeasuredPower
Cause: - Short circuit or cable break at sensor input for measured power.
Response: - Error message: Common alarm.
- Emergency operation with substitute value or last valid sensor value
depending on choosen response mode.
- Operation mode Open-Loop for emergency operation only if the substitute value.
for measured power is lower than the switch level for Closed-Loop mode.
- Error is cleared automatically when sensor values are within tolerances,
depending on choosen response mode.
Action: - Check sensor cable for short circuit or cable break.
- Check power sensor and replace if required.
- Check tolerance values for power sensor.
3020 ErrLambda 3120 SErrLambda
Cause: - Short circuit or cable break at sensor input for lambda sensor.
Response: - Error message: Common alarm.
- Emergency operation in Open-Loop mode.
- Emergency operation with substitute value or last valid sensor value.
depending on choosen response mode.
- Error is cleared automatically when sensor values are within tolerances,
depending on choosen response mode.
Action: - Check sensor cable for short circuit or cable break.
- Check lambda sensor and replace if required.
- Check tolerance values for lambda sensor.
3021 ErrCH4Content 3121 SErrCH4Content
Cause: - Short circuit or cable break at sensor input for CH4-content.
Response: - Error message: Common alarm.
- Emergency operation with substitute value or last valid sensor value.
