1. Major overhaul of Starlight Generator
a. Measure insulating resistance
with 500V Meg-ohm meter. If the reading is less than 2MΩ, the generator should
be dried. (Must disconnect AVR with generator during measuring).
b. Replace the grease in bearing
housing, and clean the surface of two shield bearing or replace the bearing.
c. Clean the interior of
generator by blowing, and take care of the all junctions.
d. Inspect all living parts, and
make sure joint nut tight and contact well.
2. Overhaul attention.
a. Take care of the disassemble
parts, and avoid to bump each other or missing.
d. Disassemble bearing and
bearing cap should be covered by clean paper to prevent dirt, and replace the
dirty grease.
e. After the generator
reassembled, rotate the rotor slowly, ensure there are not abnormal sound and
halt.
f. The bracket screws should be
driven crosswise, can't drive the screws one by one.
Paralleling operation.
Sx440 voltage regulator may be
supplied for paralleling operation, if necessary, customer must take note of it
in order. Consult with the factory for further information relative to parallel
operations.
1. AVR. wiring can't be connected
wrong. The terminal '2' and '3" are connected to the tap "U3"
and 'W3" of generator winding. It is used for 200 volt, if used for 400
volt , the AVR. would be damaged.
2. The terminal "1" and
"2" of AVR. should be shorted with jumper wire. If the external
potentiometer is used for remote adjusting voltage, the potentiometer would be
connected to the "6" and "7". Or the AVR. may be damaged
without connecting.
3. Boost exciting must use the
"12V" battery , and the generator must be stopped. Using
"24W" battery or boosting the excitation in rotating, the AVR would
be damaged.
4. The generator runs at "50
Hz" or "60Hz", should ensure the wiring right, or maybe affect
AVR working.
5. Before shut down the
generating set, first turn off the output switch, then speed down the engine.
6. Take care of the contact of
the plug and sockets, ensure them close contacting each other.
7. If the generator can't built
up, first of all, look for the causes, such as: fuse; wiring; residue voltage,
etc. Please don't adjust the potentiometer and boosting excitation before known
the causes.
8. If the engine runs at idle
speed, please don't adjust the potentiometer and boost excitation.
9. Adjusting the voltage and
stability potentiometer, please use small screw-driver and rotate slowly.
Maintenance.
a. Generator should be installed in the dry, clean, ventilating place, and to prevent the direct contact of wind driven dirt, rain, snow and sunlight.
b. Take note of the ventilation and heating of generator at times, and the current and voltage don't exceed the rating data.
c. The generator should not be operated at the place that full of water vapor,dust and flammable gas.
d. In general, maintenance intervals will depend upon operating conditions. Routine overhaul should be made frequently.
