• Warnings are non-critical alarm conditions and do

not affect the operation of the generator system. They serve to draw the operator’s attention to an undesirable condition. By default, warning alarms are self-resetting when the fault condition is removed.

• Electrical trips stop the generator in a controlled

manner. On initiation of the electrical trip condition, the controller de-energizes all the outputs, including the lights, to remove the load from the generator. Once this has occurred, the controller starts the cooling timer and allows the engine to cool off-load before shutting down the engine.

• Shutdown alarms stop the generator immediately.

On initiation of the shutdown condition, the controller de-energizes all the outputs, including the lights, to remove the load from the generator. Once this has occurred, the controller shuts the generator set down immediately to prevent further damage.

• DTC faults are displayed by the controller.

Table 2-1. Possible DTC Faults

Fault DTC Description

To clear alarms that stop the generator, refer to

Engine Derating

All units are subject to derating for altitude and temperature. Derating reduces the available power for operating tools and accessories connected to the receptacles. For every increase in 1,000 ft (305 m) of elevation, engine performance for this unit typically drops between 2–4%. Also, engine performance decreases about 1% for every 10 °F (5.6 ºC) increase in ambient air temperature over 72 ºF (22 ºC).

Wet Stacking

The unit is powered by a diesel engine. Diesel engines are subject to “wet stacking” if lightly loaded. Wet stacking occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load. It can also cause fouling of injectors and buildup on engine valves. Diesel engines operate properly when applied loads are between 30– 100% capacity. Appropriate generator sizing is determined by the anticipated load. If the unit is in a wet stack condition, load the unit heavily for five hours or until the exhaust is clear.

Lowering the Lights:

Referring to the “Lift / Let Down” decal on the winch, turn handle according to the specified direction to lower. No clicking will be heard because the brake system is activated.

Maintenance

The following procedures should be performed at least annually:

1. The gears and bushings of the winch must be kept

lubricated. Apply a thin film of grease to the gear teeth, and oil the bushings as needed.

2. The ratchet pawl pivot point must be kept lubri-

cated with a thin oil.

NOTE: Do not get oil or grease on the brake mechanism.

Figure 4-1. Entering Maintenance Pin

Manual Winch: Use, Operation, and Maintenance

Prior to Use

•

Inspect rope or cable and replace if damaged.

• Inspect mounting hardware for correct tightness

and torque if necessary.

• Gears, ratchet pivot point, and shaft bushings must

be kept lubricated with a thin film of oil or grease.

Operation

Raising the Lights:

1. The cable must be securely fastened to the winch

drum.

Electric Winch (If Equipped): Use, Operation, and Maintenance

• Keep the winch free of dirt, oil, grease, water, and

other substances.

• Check all mounting bolts and verify they are tight-

ened to the recommended torque values. Replace any damaged fasteners.

• Periodically inspect all connections to verify they

are tight and free of corrosion.

• Inspect the cable for visible damage every time the

winch is operated. Examples of damage are: cuts, knots, crushed or frayed portions, and broken strands. Replace cable immediately if damaged. Failure to replace a damaged cable could result in breakage.

• Regularly inspect the brake for slippage or drift.
