Diesel Generator Operation Manual Control System Part 8
Pressing the History/About button in Menu A will reveal the History/About submenus (Figure 8-1).
The control maintains a data log of the number of engine starts and number of operating hours for the engine and control, and the megawatt and maximum torque hours of the generator set. This information is stored in non-volatile memory and will not be deleted due to loss of battery power.
The About submenus provide the following generator set information:
•Generator set model and wattage (kW/MW)
•Output voltage and WYE, DELTA or SINGLE
•Frequency 50 or 60 Hz
•Rating: Standby, Prime or Base
•Version level of the controller and panel operating software
The control maintains a data log of all fault conditions as they occur, and time stamps them with the control and engine operating hours.
Up to 32 (unacknowledged) fault codes can be stored in control panel memory. Following Fault acknowledgement and correction, it is deleted from the control panel memory. However, it remains in a data log that maintains the fault code history. (The InPower service tool is required to view this data log).
The Fault History display line: 1 of 24 indicates that 24 faults are recorded and that the most recent fault (1) detected by the controller is displayed.
The Occurrences display line: In this example, 5 indicates that this is the fifth occurrence of this fault. (The InPower service tool is required to review the last four faults of this code).
Note: The Occurrences number is incremented for each new occurrence of the same fault. The controller must detect that the original sensed fault is corrected before it will increment the occurrence number for that fault.
For example, when a Low Oil Pressure fault is detected, the controller will increment the Occurrences number by 1. This fault will remain active until the controller detects that the fault is corrected. An active fault will prevent the controller from incrementing the Occurrences number each time the engine is started. When the controller detects that the oil pressure is normal the fault will become inactive, allowing the occurrences number to be incremented for the next detected Low Oil Pressure fault.
