PROBLEM POSSIBLE CAUSE WHAT TO DO
WELDING WITH V.R.D.
P10 The welding tension after
3 sec isn’t less enough
(plus in 12V dc)
1) Net R.C. defective or disconnected
from + or - welding socket
2) WDC defective.
1) Check the net R.C. Check the connections.
2) Replace the WDC.
GENERETING
P1 Voltmeter shows no volta-
ge or low voltage but ac-
tual voltage at the sockets
is OK.
1) Voltmeter malfunction 1) Replace the voltmeter.
P2 No three-phase voltage
present at the socket(s).
1) Differential switch not inserted
2) Differential switch malfunction
1) Turn on the switch.
2) Replace the switch.
P3 No single phase voltage
one socket but voltmeter
reading is normal and
there is voltage on the
other sockets.
1) Intervention of thermal switch due
to excessive current.
2) Thermal switch malfunction.
1) Push in the thermal switch.
2) Replace the thermal switch.
P4 No voltage present.
(See problem P9)
1) Short circuit present on the gene-
rator outputs.
1) Disconnect all outputs on the generator except for those on the con-
densers and re-start machine; check for voltage on condensers.
MOTOR
P1 The engine does not start
or stops immediately after
startup.
1) Low battery voltage, battery dead
or defective.
2) Presence of air in the fuel supply
circuit.
3) Circuit breaker engine protection
4) Engine solenoid
1) Check the warning light “state of the battery”: - Green colour: battery
OK - Black colour: battery to be recharged - White colour: battery to be
replaced - DO NOT OPEN THE BATTERY.
2) Carry out de-aeration on the fuel system. See engine operating manual.
3) Insert the circuit breaker. In case the problem persists, check the electrical
circuit and eliminate the problem. Call an authorised service centre.
4) See engine manual
P2 Engine stops due to
intervention of EP5/EP7/
ES.
1) Engine temperature too high or
insufficient oil pressure.
2) High temperature sensor or oil
pressure defective.
3) EP5/EP7/ES protection defective
1) Check oil level.
2) Replace the malfunctioning sensor.
3) Replace the protection.
P3 The battery is not
charged.
1) Battery charger alternator defecti-
ve.
2) Battery charger warning light de-
fective.
1) Replace
2) Replace
