9 SERVICE AND FAULT LOGS
The Service and Fault Logs have been incorporated to allow end users and service personnel to
inspect and note the controller’s performance and fault history. Utilising the controller’s existing
Status measurements and Diagnostics capabilities, information (such as the maximum temperature
the controller has operated at or the number and type of faults that have been detected) can be
stored in non-volatile memory and presented at a later date. Both the Service and Fault logs can be
selected/deselected via the setup menu on the calibrator, and when selected can be cleared at any
time to start recording new data.
9.1 Service Log
Service information is available in the Traction and Pump Status menus, where holding down
the ‘+’ key shows the maximum value of the current item, and holding down the ‘-’ key shows
the minimum value. The following items are logged:
- Maximum Battery Voltage
- Maximum Motor Current
- Maximum Controller Temperature and Minimum Controller Temperature.
To clear the log, access the “Service Log + to reset log” message at the end of the Status
menu, and follow the prompts. The service log can be enabled and disabled in the Setup
menu.
9.2 Fault Log
The Fault log is available at location 1.5 on the calibrator. Faults are grouped together by
“LED flash fault”; the types of flash fault and whether each is logged is shown below.
Generally faults that can occur during normal operation, e.g. a 2 flash driver procedure error
or an 8 flash thermal cutback indication, are not logged.
- LED off faults Logged (Internal controller power up check faults)
- 1 flash faults Logged (Personality/CRC faults)
- 2 flash faults Not Logged (Driver procedure/sequence/wiring type faults)
- 3 flash faults Logged (Mosfet/Bypass wiring type faults)
- 4 flash faults Logged (Contactor o/c or s/c or wiring type faults)
- 5 flash faults Not Logged (Not used)
- 6 flash faults Logged (Potentiometer wire off type faults)
- 7 flash faults Logged (Battery low or high faults)
- 8 flash faults Not Logged (Thermal cutback faults)
- 9 flash faults Logged (Contactor coil s/c type faults)
Each of the above logged categories contains - The total number of faults of this type, the Key hours
count of the most recent fault and a text description of the fault. An example of how the Fault Log
information is presented is shown below:
This display shows that 12 4-Flash faults have occurred and been
logged, the most recent at 12345.6 Key hours and it was a
Contactor o/c fault.
Once into the fault log menu, the left and right arrows are used to view any faults stored and at the
end of the list a “Fault Log + to reset log” message is shown, where the Fault Log can be reset in a
similar way to the service log. The Fault Log can be enabled and disabled in the setup menu.
