CHECKS AND TROUBLE SHOOTING
Never perform a test run with connected power
cables. Never touch an electrical connector without
a voltage check.
When a failure occurs, always report what you expe-
rienced before, during and after the failure. Information
with regard to the load (type, size, power factor, etc.),
vibrations, exhaust gas colour, insulation check, odors,
output voltage, leaks and damaged parts, ambient
temperature, daily and normal mainte-nance and
altitude might be helpful to quickly locate the problem.
Also report any information regarding the humidity and
location of the generator (eg. close to sea).
C
HECKING VOLTMETER
P4
– Put a voltmeter in parallel with voltmeter P4 on the control
panel.
– Check that the read-out of both voltmeters is the same.
– Stop the generator and disconnect one terminal.
– Check that the internal resistance of the voltmeter is high.
C
HECKING FREQUENCYMETER
P5
– Run the unit at normal speed.
– Put a voltmeter in parallel with frequencymeter P5.
– If the measured voltage is higher than 200 V, the frequen-
cymeter has to work properly.
If not, remove the frequencymeter, connect it with the
mains (230 V) and check that it indicates 50 Hz.
C
HECKING AMMETER
P3
– Measure during the load, by means of a clamp-on probe,
the outgoing current in the third phase (L3).
– Compare the measured current with the current indicated
on ammeter P3. Both readings should be the same.

STORAGE OF THE GENERATOR
S
TORAGE
– Store the generator in a dry, frost-free room which 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 compo-
nents 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.
P
REPARING FOR OPERATION AFTER STORAGE
Before operating the generator again, remove the wrapping,
VCI paper and silicagel 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 ex-
ceeds 5 M
Ω
.
– 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.
