Doosan Generator G60WJD-2A-T2 (B55)

Voltage Selector Door Interlock Switch

Running with no electric load, open the VOLTAGE SELECTOR door. Did this shutdown the engine and trip the main breaker?

High Containment Fluid Alarm System

Is the operation of the high containment fluid alarm system functioning properly?

Test the switch by unfastening the u-bolts holding the pipe, and then inverting the pipe to allow the switch float to fall. Did the “High Containment Level” LED illuminate?

Drain the containment area using the drain plug at either end of the containment basin. Was the drainage successful?

• Proper maintenance of the air cleaner provides maximum protection against airborne dust.

• Squeeze the rubber valve (precleaner dirt dump periodically to ensure that it is not clogged).

To service the air cleaners, proceed as follows:

2. Inspect air cleaner housing for any condition that might cause a leak and correct as necessary.

3. Wipe inside of air cleaner housing with a clean, damp cloth to remove any dirt accumulation. This will permit better seal for gasket on filter element.

• The air cleaner assembly (housing) should be inspected every 3 months or 500 hours for any leakage paths.

Note: Make sure the inlet is free from obstruction.

Ensure all electric loads are disconnected, engine is stopped and main breaker is turned on.

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

Voltage POT on control panel adjusted to full clockwise position

Voltage Output Monitor switch on the control panel set to L1-L2 position

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

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

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.
