Doosan G30-SIIIA Generator Set

The Doosan G30-SIIIA is a 26 kW (89.8 kVA) Diesel standby generator set powered by a Doosan G30-SIIIA engine. It is available at 230 V and 400 V, 3-phase, 50 Hz and rated 80 A. It holds about 4.5 L (1.2 gal) of oil and 4.5 L (1.2 gal) of coolant, with a maximum ambient rating of 40 °C. Starting uses 1 group-35 battery rated 550 CCA at 12 V. The set measures 1250×750×750 mm (49.2×29.5×29.5 in), weighs about 250 kg (551 lb) and produces 76 dBA at 7 m. An integrated tank holds 15 L (4.0 gal), roughly 5 hours of runtime.

Troubleshooting

Symptoms & remedies

SymptomRemedy
Engine runs but generator will not take loadCheck 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 gaugesFail 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 SHUTDOWNThis indicates a fault condition detected by the engine ECU and transmitted to the DSE controller.
CAN DATA FAILIndicates failure of the CAN data link to the engine ECU. Check all wiring and termination resistors (if required).
Inaccurate generator measurements on controller displayCheck 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 configurationWhen 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.
