100 kW TACTICAL QUIET GENERATOR SET
OPERATION UNDER USUAL CONDITIONS Continued
OPERATING PROCEDURES Continued
If generator set is to be operated in parallel with another unit, refer to PARALLEL UNIT
High voltage is produced when the generator set is in operation. Never attempt to start the
generator set unless it is properly grounded. Failure to comply can cause injury or death to
Operating the generator set exposes personnel to a high noise level. Hearing protection must be
worn when operating or working near the generator set when the generator set is running. Failure
to comply can cause hearing damage to personnel.
The ideal load for the generator set is 80% of rated capacity. When operated at less than 80% of
rated load, the diesel engine operates at lower temperatures and burns fuel incompletely resulting in
carbon and moisture in the exhaust and carbon buildup or wetstacking in the engine. To avoid
damage to the engine, if possible, mission loads should be distributed among available generator sets
to achieve an average 80% load on each generator set.
The minimum load that the generator set should be operated at is 25% to 30% of its rated capacity.
Operating at lower loads for long periods of time may damage the engine and cause wetstacking and
damage to the engine. Engines operated at low loads for long periods of time should be operated at
full load for a few hours until the wetstacking residues are burned out. This should be performed
every 300 hours of generator set operation.
At temperatures below 30F (1C), the cold weather starting aid will be activated.
In normal operating temperatures, the EMCP will temporarily display low temperature alarm code
AL2 upon startup. This is a normal part of the operation and the fault code will go away when
starting is complete.
