4-8 Operation
MN2417
Pre−Start Procedure Before attempting to start the generator set, several things must first be verified or
performed. These are:
1. Fill system fuel tank with clean, fresh diesel fuel.
2. Fill engine crankcase to full mark with clean, fresh lubricating oil per engine
manufacturer operating guide.
3. Radiator coolant should be checked at the beginning of each day and filled in
compliance with the engine manufacturer’s guidelines.
4. Secure the generator for operation.
a. Skid mounted − the power generating system should be mounted to a smooth,
hard surface suitable for supporting the system under all stress conditions.
b. Trailer mounted − block wheels to prevent accidental movement.
Use jack (Figure 4-1) to level the generator.
c. Adequate clearance must be provided for access doors to fully open.
Note: The exhaust also exits radiator end. When positioning a generator system ensure position
does not cause a concentration of toxic emissions.
5. Place voltage select switch in the correct position 208/120, 240/120 or 480/277VAC
and pad lock it in position if required (Figure 4-3).
6. Carefully inspect all Individual load cables for broken insulation or other signs of
damage. Never use a damaged cable. Replace it before usage.
7. L1, L2, L3, Neutral and Ground cables must be brought into load block compartment
through access hole in base of enclosure.
8. Ensure that wires are properly connected and connections are secure.
9. Ensure that an external ground connection is made when required for safety.
10. Ensure that the Remote Start wires are properly connected, if used.
11. Use disconnect at the load to turn off the load. Do not start engine with load switched
“on”. Allow engine to come up to speed and warm up before load is switched on.
Caution: Large “Engine Compartment Doors” on each side of enclosure must remain closed during
operation. If doors remain open, engine will overhead due to insufficient air flow around
engine.
12. Ensure that Engine Compartment doors are closed for proper ventilation.
Note: Receptacle Panel Load cables may be routed into the receptacle compartment through the
Enclosure Electrical Access Panel after generator is started and has warmed up.
Operating Procedures The engine−generator controller is designed to start and stop an engine from either AUTO
“Automatic” mode or Manual “NOT IN AUTO”. Refer to Figure 4-6.
Manual Start Procedure
1. Press Mode" until “Not in AUTO” LED is ON, control is in MAN mode.
2. Press “Start”.
3. The controller closes GCB after engine is running and generator parameters are within
limits.
Manual Stop Procedure
1. Use disconnect at the load to turn OFF the load. Allow generator cool down if needed.
2. Press “Stop”. Press Mode" until control is in OFF mode.
AUTO Start Procedure
1. Press Mode" until control is in AUT mode.
In Auto mode, the generator will start when the remote start input closes.
GCB is closed automatically when generator voltage is within limits.
2. In Auto mode, the generator will stop when the remote start input opens.
