Troubleshooting
16Fault codes
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 81 u | Generator set output frequency cannot be maintained. | ||
| 59 | High AC voltage shutdown (Output voltage on any phase exceeds pre-set values). | ||
| 27 | Low AC voltage shutdown (Voltage on any phase has dropped below a preset value). | ||
| 96 | Lamp: Shutdown | Indicates that the engine oil temperature is above normal and has reached the shutdown trip point. | |
| 202 | Lamp: Warning | Indicates engine is operating near cooling system capacity (monitor condition). Increase in load or higher ambient temperature may cause High Coolant Temp (1) shutdown. | Review code 1 correction list for other possible causes. |
Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Output voltage on any phase exceeds pre-set values. | Values adjustable from 105-125% of nominal voltage, with time delay adjustable from 1-10 seconds. Default value is 110% for 5 seconds. | |
| Voltage on any phase has dropped below a preset value. | Adjustable over a range of 50-95% of voltage, time delay 2-20 seconds. Default value is 90% for 5 seconds. | |
| Low oil pressure or high coolant temperature | The control (with graphical display) will light a yellow Warning lamp or a red Shutdown lamp and display a message on the graphical display. A control without the graphical display indicates a shutdown condition by intermittent flashing of the status indicator. | |
| Unexpected start-up or failure to crank | Remote input | Verify that the remote input is not causing the symptom or isolate the control from these inputs before troubleshooting the control. |
| Equipment damage due to wrong calibration file | Do not swap Baseboards from another genset model and only use the calibration file shown on the nameplate. | |
| Features not available for troubleshooting base board | Confirm that the feature is installed and enabled prior to trouble-shooting the base board for symptoms related to a feature. | |
| Shutdown condition | Make sure that parameter adjustments and time delays, related to the fault condition, have been appropriately set for the application. It may be necessary to write the initial capture file to the device or update the calibration file. | |
| Shutdown or unexpected start-up | Press the button to switch to the Off mode. Turnoff or remove AC power from the battery charger. Remove the negative (–) battery cable from the generator set starting battery. | |
| L not start in remote mode, but starts in manual mode. | The remote start switch or configurable wiring is faulty. | Reset the control. Attempt to start, and check for ground at TB1-11. If ground level is not present, isolate to the remote switch or configurable wiring. Repair as necessary. If ground is present, go to next step. |
| The menu display Auto button, harness or the Base board is bad. | Check for continuity between P11-16 (AUTO) to P11-8 (GND). If no continuity when pressing the menu display Auto button, isolate to front membrane panel or wiring harness. If there is continuity, the Base board is bad. | |
| Increase in load or higher ambient temperature may cause High Coolant Temp (1) shutdown. | Review code 1 correction list for other possible causes. |
