OPERATION
PRE-START INSPECTION
Before starting the generator for the first time, the following
inspection checks are recommended:
1. A visual inspection should be made for any loose parts,
bad connections, or foreign materials.
2. Bar the set over by hand for at least 2 revolutions to be
sure that there is no interference and that the set turns
freely. If the set does not turn freely, check for
clearance in the generator and exciter air gap.
3. Check all wiring against the proper connection
diagrams, and ensure that all connections and
terminations are tight and properly insulated.
WARNING
MAGNAPLUS GENERATORS MAY HAVE VOLTAGE
PRESENT AT THE LEAD TERMINALS WHEN THE
SHAFT IS ROTATING. DO NOT PERMIT
OPERATION OF THE GENERATOR UNTIL ALL
LEADS HAVE BEEN CONNECTED AND INSULATED.
FAILURE TO DO THIS MAY RESULT IN PERSONAL
INJURY OR EQUIPMENT DAMAGE
4. Verify that all equipment is properly grounded (earthed).
5. Clear the surrounding area of any materials that could
be drawn into the generator.
6. Check all fasteners for tightness.
7. Check all access plates, covers, screens and guards. If
they have been removed for assembly or inspection,
reinstall and check for security.
8. Review all prime mover prestart-up instructions, and
ensure that all recommended steps and procedures
have been followed.
9. Remove any masking materials affixed during painting.
Inspect the generator, prime mover, and any accessory
equipment to ensure that nameplates, and all safety
warning / caution signs and decals provided with the
equipment are in place and clearly visible.
Note: It is strongly recommended that the authority
having jurisdiction over the installation site be
consulted to determine if any additional warning or
caution notices, or additional safety devices are
required by local codes / standards. Any such
required notices or devices should be installed
prior to initial startup.
START-UP
The following procedure should be followed when starting
the generator set for the first time.
1. The generator output must be disconnected from the
load. Be sure that the main circuit breaker or fused
disconnect is in the open position.
2. Open the input power to the automatic voltage
regulator. Remove the fuse or disconnect and insulate
one of the regulator input power leads. (See separate
regulator manual)
3. Verify that all prime mover start-up procedures have
been followed.
4. If the unit is provided with space heaters, ensure that
they are de-energized. In some installations, a set of
auxiliary contacts on the main circuit breaker or transfer
switch will automatically open the space heater circuit
when the generator is connected to the load.
5. Start the prime mover, and adjust it for proper speed.
See generator nameplate.
