| 51 | High Current warning/shutdown | ||
| 5134 | Unknown Shutdown at Idle | ||
| 5365 | Fault Code on Secondary Source (Information that the Fueling Has Been Shifted to Secondary Source) | ||
| 5669 | Engine Combustion (Shutdown) | ||
| 59 | High AC voltage shutdown | ||
| 59 | High AC voltage shutdown (Output voltage on any phase exceeds pre-set values). | ||
| 6518 | Cold Start Idle Active (Event) | ||
| 81 o | Over frequency shutdown/warning | ||
| 81 u | Generator set output frequency cannot be maintained. | ||
| 81 u | Under frequency shutdown | ||
| 96 | Lamp: Shutdown | Indicates that the engine oil temperature is above normal and has reached the shutdown trip point. | |
| Code 141 | - Oil pressure sensor output out of range low | ||
| Code 143 | - Engine oil pressure low (warning) | ||
| Code 144 | - Engine coolant temperature out of range low (warning) |
| Symptom | Cause | Remedy |
|---|---|---|
| Any spillage that occurs during fueling or during oil top-off or oil change must be cleaned up before starting the generator set. | Clean up any spillage before starting the generator set. | |
| Battery voltage warning | Status of battery charging system (failure) | |
| Emergency stop signal is received | The generator set immediately shuts down and cannot run or crank with the E-stop switch engaged. | |
| 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. | |
| Fire Hazard | Contaminated insulation is a fire hazard. | Remove any contaminated insulation and dispose of it in accordance with local regulations. |
| High coolant temperature warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. | |
| Increase in load or higher ambient temperature may cause High Coolant Temp (1) shutdown. | Review code 1 correction list for other possible causes. | |
| 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. |
| Low coolant temperature warning | Indicates that engine temperature may not be high enough for 1 min. and start or proper load acceptance. | |
| Low lube oil pressure warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. | |
| 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. | |
| 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. | |
| Over/under frequency sensor overfrequency sensing dropout adjustable from 105-115% of nominal | Dropout adjustable delay from 0.1-15 sec. | |
| Over/under frequency sensor underfrequency sensing pickup and dropout adjustable from 85-100% and 70-85% | Dropout adjustable delay from 0.1-15 sec. | |
| Overvoltage sensor dropout adjustable from 105-135% of nominal | Dropout adjustable delay from 0.5-120 sec. | |
| Sensor failure indication | Logic is provided on the base control to detect analog sensor or interconnecting wiring failures. | |
| 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. | |
| 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. | |
| Time delay of 0-600 seconds prior to shutdown after signal to stop in normal operation modes | Default for both time delay periods is 0 seconds. | |
| Time delay start and stop (cooldown) configurable for time delay of 0-300 seconds prior to starting after receiving a remote start signal | Control provides retransfer time delays including time delay emergency to normal (0-1800 sec), programmed transition delay (0-600 sec), and time delay engine cooldown (0-3600 sec). | |
| Undervoltage sensor pickup and dropout adjustable from 85-100% and 75-98% | Dropout adjustable delay from 0.1-30 sec. | |
| 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. |
| 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. |
