Measuring Alternator Insulation Resistance; Storage Of The Generator; Storage; Preparing For Operation After Storage - Atlas Copco Qas 58Jd Manuel D'instructions

(*) MEASURING THE ALTERNATOR INSULATION RESISTANCE
A 500-V meggar is required to measure the alternator insulation
resistance. If the N-terminal is connected to the grounding system, it
must be disconnected from the ground terminal. Disconnect the
AVR.
Connect the meggar between the ground terminal PE and terminal
L1 and generate a voltage of 500 V. The scale must indicate a
resistance of at least 5M? .
Refer to the alternator operating and maintenance instructions for
more details.

STORAGE OF THE GENERATOR

STORAGE

Store the generator in a dry, frost-free room that is well
-
ventilated.
Run the engine regularly, e.g. once a week, until it is warmed
-
up. If this is impossible, extra precautions must be taken.
Consult the engine' s operator manual.
-
Remove the battery. Store it in a dry, frost-free room. Keep the
-
battery clean and its terminals lightly covered with petroleum
jelly. Recharge the battery regularly.
- Clean the generator and protect all electrical components
against moisture.

- Place silica gel bags, VCI paper (Volatile corrosion
inhibitor) or another drying agent inside the generator and
close the doors.
- Stick sheets of VCI paper with adhesive tape on the
bodywork to close off all openings.
- Enclose the generator, except the bottom, with a plastic
bag.

PREPARING FOR OPERATION AFTER STORAGE

Before operating the generator again, remove the wrapping, VCI
paper and silica gel bags and check the generator thoroughly (go
through the checklist " Before starting" ).
Consult the engine' s operator manual.
-
Check that the insulation resistance of the generator exceeds
-
5M? .
Replace the fuel filter and fill the fuel tank. Vent the fuel
-
system.
Reinstall and connect the battery, if necessary after being
-
recharged.
Submit the generator to a test run.
