Heinzmann Programmer 2 Manual page 49

Actions: - Check injection pump resp. throttle valve, replace if necessary.
- Check mechanical parts (linkage).
- Check cables to actuator.
- Check actuator, replace if necessary.
Note: These parameters are implemented only in the PRIAMOS III series.
3056 ErrFeedbackRef
Cause: Error in feedback system of actuator, actuator not connected.
Response: - Governor cannot be put into operation.
- Emergency shutdown.
Actions: - Check feedback cable to actuator.
- Check actuator, replace if necessary.
- Check error limits for feedback reference:
1956 FeedbackRefErrLow / 1957 FeedbackRefErrHigh
3059 ErrFeedbackAdjust
Cause: Automatic calibration of the actuator could not be performed, wrong input
of reference values for actuator.
Response: - Governor cannot be put into operation.
Actions: - Check voltage supply and supply lines to actuator.
- Check feedback cable to actuator.
- Check actuator, replace actuator if necessary.
- Engine stop switch must be opened (indication parameter 2810 Switch-
EngineStop = 0) to perform automatic calibration of actuator with 2-
quadrant-operation.
- Check reference values and error limits for feeedback
- Programme feedback error limits
1952 FeedbackErrorLow = 0
1953 FeedbackErrorHigh = 65535
1956 FeedbackRefErrLow = 0
1957 FeedBackRefErrHigh = 65535,
store values, restart governor by reset and repeat automatic calibration.
- Set error limits again.
