high pressure water spray to clean the alternator. The humidity of alternator will decrease
insulation resistance. The alternator shall be dried. Please refer to Alternator’s Operation and
Maintenance Manual for the method of drying and detailed maintenance.
Control panel
Daily maintenance for the control panel shall ensure the cleanness of its surface, make the
indicator more clear and easy for reading, and the operation button flexible and reliable.
During the generator set’s running period, vibration will cause the shift of “0” position in the
instrument of control panel and loose of tightened parts, and therefore periodically check the
instrument of the control panel and parts and cable’s connections are very important.
Repair for the control panel can only be done after thorough learning of the principle of this
control panel (please refer to Control Panel Operation Manual for details)
Start battery
Batteries which have been stored in a long time shall be properly charged before being used,
so that to ensure normal capacitance of the battery. (Densimeter can be used to check the
actual capacitance of the battery)
Normal operation and battery charging will cause some water inside of the battery being
vaporized. And therefore constant fluid infusion is needed. Before fluid infusion, first the conta-
minant around the adding hole shall be cleaned so that to avoid them falling into the battery.
Then open the adding hole, add proper amount of distilled water or purified water. Do not add
too much (shall be according to the indicating line in the battery polar plate), Otherwise the
inside electrolyte will overflow from the adding hole when the battery is under discharge or
charging, which will cause contamination to the ambient material and environment.
Please do not use the battery to start the generator set under low temperature because the
battery capacitance can not output normally under low temperature, and long time discharge
may cause battery malfunction(crake or explode).
Warning:
• The battery of the backup generator set shall be periodically maintained and charged. It is
suggested that users can buy floating charger for the battery.
