WinGD X92-B - Special failures; Troubleshooting of UNIC-flex failures

For the complete list of failure messages refer to the document - Modbus to AMS signal list - of
the engine.
10.3.2 Special failures
WinGD has specified a few special failures (refer to Table 10-64 - Special failures) that makes it
necessary to start other steps.
Tab 10-64 Special failures
ID Failure text Failure type
45 Crank Angle Measurement Fail CCM #1 & MCM Major / SLD
47 Crank Angle Measurement Fail MCM Minor
96 Module Fail MCM Minor
If one of these special failures occur, the ECS automatically does the steps that follow:
•
The ECS changes the active control location to “ECR manual”.
•
The ECS changes to the “Fuel command mode”.
In this condition the ECS cannot set a setpoint for a command. Thus obey the rules that follow:
•
If failure 45 occurs the operator must set the fuel command setpoint for slowdown manually.
•
If failure 47 or 96 occurs the operator can set the fuel command setpoint if necessary.
10.3.3 Troubleshooting of UNIC-flex failures
If there is an indication of a UNIC-flex failure, use the data that follows to find the failure and to
repair it:
•
Use the failure ID to find the related system or item.
•
If applicable, compare the indicated values with the values on the local instruments.
•
Make sure that the related items are mounted correctly and can operate correctly.
•
Make sure that the related shut-off valves are in the correct operation positions.
•
Do a check of the related cable connections.
•
Do a check of the related cable or plugs for damage.
•
Do a check of the related item for damage.
•
Use a multimeter to do a check of the power supply.
•
Use a multimeter to do a check of the sensor signal.
•
Use a multimeter to do a check for a short circuit or a ground fault.
•
If applicable, do a check of the terminating resistors for correct connection.
•
Repair the faults, or temporarily repair defective cables with insulation tape.
•
If necessary, replace damaged items.
If you cannot repair a fault, speak to or send a message to WinGD.
