Figure 162
Engine Screen Detector Fault
Select the faulty detector to access the Detector Status Screen.
Figure 163
Detector Status Screen Memory Fault
Identify the fault being indicated, in this case a Memory fault.
Alternatively an inspection of the engine event log, see section 3.6, will list the event:
Gain Digipot Read Fault Detector X
Having established which detector is in fault the following steps should be followed.
1.
Disconnect the detector cable from the detector, to remove the power from the detector.
2.
Reconnect the detector.
3.
Accept and Reset the fault.
4.
Check if the memory fault reoccurs.
If the memory fault does not reoccur no further action is required.
If the memory fault reoccurs the detector has failed and should be replaced.
5.2.8
Offset Digipot Read Fault
The offset digipot is a component within a detector used to ensure the correct calibration of the detector.
The digipot value is set during the production of the detector and cannot be changed. The detector
constantly monitors the digipot value to ensure that it has not been corrupted and communicates the
fault to the Control Unit If an error in the value is identified an Offset Digipot Read Fault will be indicated.
To identify which detector is at fault, from the Engine Overview Screen, Figure 148, select the required
engine.
