DPX7500 DIESEL GENERATOR

Connect the large loads onto the generator first. If everything is functional, smaller loads can then

be added. If the generator shuts off, it may be because the load being drawn by all the various

devices are too high. In this event, decrease the number of small devices until everything is

functional. The total drawn power should not exceed the maximum output power of the generator.

Please see Table 1-1 for technical specifications of what the generator can output. In order to reset

the generator after overdrawn power, let it sit for several minutes. If the indication of the

voltmeter is too high or too low, adjust the speed accordingly. If there are problems, stop the

generator immediately and fix the issue.

4. During operation, the generator should be in a place that has very good ventilation.

Never cover the engine to solve a ventilation problem, as this will damage your

equipment.

Note: Do not start more than two devices simultaneously. Each device should be

started one by one to prevent overloading the generator.

The generator should be running at 3600 revolutions per minute in order to

achieve the (60 Hz) frequency. The speed of the engine can be adjusted from the

speed governor.

2-7.3 Charging the battery

1. For the electric starter on the generator sets, the 12V battery is automatically

charged through the regulator on the side of the engine when it is running.

2. If the generator is not used for long periods of time, the battery should be

disconnected to avoid energy loss from the battery.

3. Do not connect the negative and positive terminals of the battery together at any

time. Doing so will cause the battery to explode and cause serious injuries.

4. Do not reverse the polarities when attaching the battery cables to the battery.

Doing so will damage both the battery and the electric starter.

5. When charging the battery, the battery produces flammable gases. Do only on well

ventilated area.

Do not smoke, let flames, and sparks get near the battery while it is charging as

this may cause a fire.

To avoid sparking while connecting the cables to the battery, first, connect the cables

to the battery then to the motor. To disconnect battery cables, first disconnect the

motor end of the cable.

2-8 Stopping the generator

1. Take the electrical load of f the

generator .

2. Put the speed handle in the "RUN"

position and let the engine run for 3

minutes after unloading. Do not stop the

engine immediately let it warm down.

Stopping the diesel engine suddenly may

the temperature of the engine abnormally

lock the nozzle and damage the diesel

engine.

1. If the speed handle is in the "Stop position and the engine is still running , turn the

fuel switch to the "OFF" position or loosen the high pressure oil pipe nut. The engine

could be stopped more than one-wayother than the speed handle way.

2. If you cannot stop the engine with a load on it, then remove the load first than stop

the engine.

3. Press down on the brake handle

4. If equipped with an electric starter , turn the key to the "Of f" position

5. Put the fuel handle to the "S" position

6. Finally, pull slowly on the recoil handle until you feel resistance (this is when the

piston is on the compression stroke, where the intake and exhaust valves are closed).

What this does is prevent the engine from rusting when not in use.
