Diesel Gen-set Operation Instructions

temperature of winding is 20 .
℃
If insulation resistance is still lower than 1M
Ω
after above drying process, carry out
polarization test of coil.
If all parts cannot meet the requirement of 1M
Ω
insulation resistance, wind the coil
again or clean alternator again.
Never put the alternator into service when minimum insulation resistance requirement
is not met.
Measurement of insulation resistance shall be carried again after winding is dried up,
in order to ensure that the above minimum resistance requirement can be met.
7. Cleaning method of air filter on alternator
Warning: live parts would be contacted when removing parts of air filter, so
removal of these parts is allowable only after stopping.
Remove parts of air filter from air filter cover and soak or wash these parts with
proper oil removal agent until these parts are fully cleaned. In addition, dry these
parts fully before being reinstalled.
8. Maintenance of the Gen-set
The engine and AC alternator would be damaged when the Gen-set is not used for a
long period of time. Correct storage of the Gen-set may reduce this damage to the
minimum.
8.1 It is the optimal if the Gen-set is placed in an environment in which ambient
temperature is 20 ~25 , relative humidity is 20%~70% and air pressure is
℃
℃
70kPa~106kPa.
8.2 Before sealing-up, all rusts shall be removed with proper methods and all parts
(lubricating oil line, fuel system and supercharger, etc.) treated with protective agent
shall be cleaned completely. Protection procedures of the Gen-set are as follows:
