STARTING-UP THE GENERATOR
The following procedure should be followed
for starting-up the generator for the first time:
1.The generator output must be disconnected
from the load. Be certain that the main circuit
breaker is open.
2. Disable the voltage regulator by removing
the fuse.
WARNING
DO NOT OVERSPEED THE
GENERATOR. EXCESSIVE
CENTRIFUGAL FORCES COULD
DAMAGE THE ROTATING FIELDS. BE
PREPARED FOR AN EMERGENCY
SHUTDOWN.
3. Follow the manufacturer's instructions and
start the prime mover. Check the speed and
adjust to the RPM shown on the generator
nameplate.
4. Replace the regulator fuse and adjust the
voltage to the required. Check all line to line
and line to neutral voltages to be sure they are
correct and balanced. If the voltages are not
correct shut down immediately and recheck all
connections.
5. Close the main circuit breaker and apply the
load.
6. Monitor the generator output current to
verify it is at or below nameplate amps.
7. Adjust engine speed at full load to 1800
rpm for 60 hertz, 1500 rpm for 50 hertz.
(Refer to prime mover/governor instruction
manuals.)
8. Before stopping the engine, remove the load
by tripping the main circuit breaker.
FIELD FLASHING
The standard MagnaMAX generator is supplied
with a PMG (permanent magnet generator). It will
never require field flashing. In rare cases where a
special generator may be furnished without a
PMG, refer to the factory for more detailed
information. Include the complete generator model
and serial number.
VOLTAGE ADJUSTMENTS
The voltage regulator controls the generator output
voltage. There is a cover to access the control
panel on the side of the generator conduit box
Figure 4-2 Regulator Access
Refer to the regulator manual for detailed
information. In cases where special or remote
mounted regulators are used, refer to instructions
supplied by the generator set assembler and to the
voltage regulator manual.
