Doosan Generator G570WCU-2B-T2 (C37)

Check for loose wire routing clamps. Clamps must be secure and properly mounted. Also check wiring for wear, deterioration and vibration abrasion.

Check for evidence of arcing around electrical terminals.

Check that the grounding circuit is in accordance with the National Electrical Code Article 250-122 and the local code requirements. As a minimum, the copper wire size should be American Wire Gauge 8 (AWG#8) from the grounding terminal, frame, generator and engine block.

Check for loose, or frayed wiring insulation or sleeving.

Check for water in the fuel filter/water separator unit. Some engines have a translucent bowl for visual indication, and others have a drain valve below the primary element.

Clean the air vents of any obstruction or debris.

Check Evidence of Arcing around electrical terminals.

Check Loose Wire Routing Clamps.

• Servicing or troubleshooting must be carried out strictly in accordance with instructions so as to avoid the risk of accidents and to maintain the machine in its original state.

• All such operations performed on the alternator should be undertaken by personnel with training of electrical and mechanical components.

• Before any intervention on the machine, ensure that it cannot be started by a manual or automatic system and that you have understood the operating principles of the system.

• It is advisable to check that circulation of air is not reduced by partial blocking of the suction and discharge louvres: mud, fibre, grease, etc.

• Cleaning product for the windings

WARNING! Do not use: Trichlorethylene, perchlorethylene, trichloroethane and any alkaline products.

With all electric loads disconnected, engine stopped and main breaker turned on, turn VOLTAGE SELECTOR Switch to 277/480V position, and close and latch the VSS door.

Voltage POT(P2) on regulator adjusted to full counterclockwise position

Voltage POT on control panel adjusted to full clockwise position

Set the VOLTAGE OUTPUT MONITOR switch on the control panel to L1-L2 position.

Voltage POT(P2) on the regulator adjusted to read 500V on AC voltmeter

Stability POT(P3) adjusted counter clockwise until the AC volts within ± 1 volt

Then turn the adjusting Stability POT (P3) some 5-10 degrees clockwise.

• Every six months or 500 hours, or less if fuel is of poor quality or contaminated, replace the bowl elements(s).

• The engine coolant system is normally filled with a 50/50 mixture of water and ethylene glycol.

• This permanent type anti-freeze contains rust inhibitors and provides protection to -35°F (-37°C). The use of such a mixture is recommended for both summer and winter operation.

• When using water alone, be sure to add a reputable brand of rust inhibitor to prevent internal corrosion.

• It is recommended to test the freezing protection of the coolant every six months or prior to freezing temperatures. Replenish with a fresh mixture every twelve months.

3. Check Control Compartment (Interior).
