| Symptom | Cause | Remedy |
|---|---|---|
| Engine runs but generator will not take load | Check Warm up timer has timed out. Ensure generator load inhibit signal is not present on the module inputs. Check connections to the switching device. | |
| Incorrect reading on Engine gauges | Fail to stop alarm when engine is at rest Check engine is operating correctly. Check that sensor is compatible with the module and that the module configuration is suited to the sensor. | |
| CAN ECU WARNING CAN ECU SHUTDOWN | This indicates a fault condition detected by the engine ECU and transmitted to the DSE controller. | |
| CAN DATA FAIL | Indicates failure of the CAN data link to the engine ECU. Check all wiring and termination resistors (if required). | |
| Inaccurate generator measurements on controller display | Check that the CT primary, CT secondary and VT ratio settings are correct for the application. Check that the CTs are wired correctly with regards to the direction of current flow (pt, p2 and s1, s2) and additionally ensure that CTs are connected to the correct phase (errors will occur if CT1 is connected to phase 2). Remember to consider the power factor (kW = kVA x powerfactor). The controller is true RMS measuring so gives more accurate display when compared with an 'averaging' meter such as an analogue panel meter or some lower specified digital multimeters. Accuracy of the controller is better than 1% of full scale. Generator voltage full scale is 415V ph-N, accuracy is ±4,15V (1% of 415V). | |
| Module appears to 'revert' to an earlier configuration | When editing a configuration using the PC software it is vital that the configuration is first 'read' from the controller before editing it. This edited configuration must then be 'written' back to the controller for the changes to take effect. When editing a configuration using the fascia editor, be sure to press the Auto Mode button to save the change before moving to another item or exiting the fascia editor. | |
| Engine does not start | Starter does not turn. | Battery discharged, Bad cable connections., Starter or starter switch failure., Safety relay failure. |
| Engine fires but stalls immediately | Air in the fuel system. | |
| Unit is inoperative | Read/Write configuration does not operate Check the battery and wiring to the unit. Check the DC supply. Check the DC fuse. | |
| Unit shuts down | Check DC supply voltage is not above 35 Volts or below 9 Volts. Check the operating temperature is not above 70°C. Check the DC fuse. | |
| Fail to Start is activated after pre-set number of attempts to start. | Check wiring of fuel solenoid. Check fuel. Check battery supply. Check battery supply is present on the Fuel output of the module. Check the speed-sensing signal is present on the module's inputs. | |
| Continuous starting of generator when in the Auto Mode. | Check that there is no signal present on the 'Remote Start' input. Check configured polarity is correct. Check the mains supply is available and within configured limits. | |
| Generator fails to start on receipt of Remote Start signal. | Check Start Delay timer has timed out. Check signal is on 'Remote Start' input. Confirm correct configuration of input is configured to be used as 'Remote Start'. Check that the oil pressure switch or sensor is indicating low oil pressure to the controller. | |
| Pre-heat inoperative | Check wiring to engine heater plugs. Check battery supply. Check battery supply is present on the Pre-heat output of module. Check pre-heat configuration is correct. | |
| Starter motor inoperative | Check wiring to starter solenoid. Check battery supply. |
