2.
Insure that all engine pre-start and start-up procedures have been followed.
3.
Start the engine and adjust it for proper speed. For 60 Hertz operation, synchronous speed is
1800 RPM.
4.
Check all Line
to
Line and Line
to
Neutral voltages for balanced voltage.
If
voltages are
unbalanced, shut down the equipment and check for improper wiring. Correct any mistakes, restart
the set and again check for voltage balance.
If
the problem persists, consult the factory.
6. Close the main circuit breaker
to
the load.
7.
Monitor the generator output current
to
verify it is
at
or
below nameplate value.
8.
Check generator speed under load. Adjust as necessary. (Refer
to
engine/governor manuals)
Shut
Down
Procedures
There are no specific instructions for shut down
of
the generator, but several good engineering
practices should
be
observed
to
prolong equipment
life.
I. It
is
advisable
to
disconnect all loads (open main circuit breaker) prior
to
shut down.
2. Isolate any condition that could allow the generator
to
see a voltage
at
its terminals while
at
rest.
Failure
to
do this could result in personnel injury or equipment damage.
MAINTENANCE
Routine
Maintenance.
Your
Lima®
MAC generator has been designed
to
be as reliable and trouble
free as is possible. However, costly
repairs and down time can
be
minimized by operating the unit
under conditions that are compatible with those at which the equipment was designed
to
operate. (See
Operation Section) The following maintenance procedures should
be
followed
to
insure long
equipment life and satisfactory performance:
1.
Routinely check intake and exhaust air screens
to
insure that they are clean and free
of
debris.
Clogged intake air screens will reduce cooling
air flow, and may result in the unit operating
at
dangerously high temperatures, and reduce the generator's life. This inspection and cleaning should
be
done in conjunction with prime mover air filter cleaning and/or change out.
2. Periodically (approximately every thousand operating hours) check the bearing.
Your
generator
is equipped with a pre- lubricated for life bearing which does not require routine lubrication. Bearing
check may
be
done by listening
to
the bearing during operation with a stethoscope. An alternative
method is
to
apply the blade
oflong
shanked screw driver
to
the
bearing carrier adjacent
to
the
bearing. Keeping well clear
of
any rotating elements, place your
ear
to
the handle and listen for
excessive bearing noise.
If
undue noise exists; shut the unit down, inspect the bearing and replace it,
if
necessary, following instructions in the service section
of
this manual.
