| Symptom | Cause | Remedy |
|---|---|---|
| Below normal engine temperature | Defective thermostat. | Remove and check thermostat. |
| CAN DATA FAIL | Indicates failure of the CAN data link to the engine ECU. Check all wiring and termination resistors (if required). | |
| CAN ECU WARNING CAN ECU SHUTDOWN | This indicates a fault condition detected by the engine ECU and transmitted to the DSE controller. | |
| Continuous generator overloading may cause high operating temperatures that can damage the windings | Keep the load within the nameplate rating | |
| 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. | |
| Engine cranks but will not start | Incorrect starting procedure. | Verify correct starting procedure. |
| 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. | |
| Engine hard to start or will not start | Engine starting under load. | Remove load. |
| Engine knocks | Low engine oil level. | Add oil to engine crankcase. |
| Engine overheating | See 'Engine Overheats'. | |
| 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. | |
| Engine runs irregularly or stalls frequently | Low coolant temperature. | Remove and check thermostat. |
| Exhaust restricted | Check and correct exhaust restriction. | |
| 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. | |
| Faulty injection pump or nozzles | Consult authorized diesel repair station for repair or replacement. | |
| Fuel filter plugged or full of water | Replace fuel filter or drain water from filter. | |
| 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. | |
| Heavy exhaust smoke when the engirie is first started | Caused by the inhibitor oil | |
| If the engine fails to start at first try | Inhibitor oil used at the factory may have fouled the spark plugs | Remove the plugs, clean in a suitable solvent, dry thoroughly and install |
| 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). | |
| 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. | |
| Injection pump not getting fuel or air in fuel system | Check fuel flow at supply pump or bleed fuel system. | |
| Injection pump shut-off not reset | Turn key switch to 'OFF' then to 'ON'. | |
| Lack of power | Engine overloaded. | Reduce load. |
| Low coolant temperature | Remove and check thermostat. | |
| Low power | Carbon brushes are excessively worn | |
| 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. | |
| No fuel | Check fuel in tank and manual shut-off valve. | |
| 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. | |
| Shutdown is activated and the temperature gauge shows temperature within normal temperature range | A. Check the engine crankcase oil level. b. If the oil level is low, fill with recommended lubricating oil and restart. Watch the oil pressure gauge carefully and shut off the engine if it does not show a normal reading (20-60 PSI) after a few seconds of operation. c. If the oil level is normal, DO NOT restart the engine. Call your dealer for assistance. | |
| Starter motor inoperative | Check wiring to starter solenoid. Check battery supply. | |
| 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. | |
| When Engine Fails to Start | Check if choke lever is in its proper position. Check if fuel cock is open. Check fuel level. Check to make sure generator is not connected to an appliance. Check spark plug for loose spark plug cap. Check spark plug for contamination. Check if engine switch is in OFF. Set the choke lever to "CLOSE" position. If closed, open fuel cock. If empty, refill fuel tank making sure not to overfill. If connected, turn off the power switch on the connected appliance and unplug. If loose, push spark plug cap back into place. Remove spark plug and clean electrode. Turn engine switch to ON. | |
| When No Electricity Is Generated at Receptacle | Check if AC circuit breaker is in the "ON" position. Check AC receptacle and DC terminals for loose connection. Check to see if engine starting was attempted with appliances already connected to generator. |
