2. DIAGNOSIS CHART

SOLUTIONS
COME ON
!" check the primary connection
!" verify F1 welding set fuse
!" verify the state of K1 primary
contactor
!" verify the state of the On/Off
selector switch
COMES ON
!" check the primary connection
!" verify fuse F2
!" check wiring of K1
!" check wiring of filter card
ON
!" check the jumper on front panel
!" check connectors B6, B9
!" verify fuses F2 and F3 on regulation
card
!" verify +15, -15, and +5 volt power
supplies if power supply fault
the regulation card;
otherwise, press wire feed: if wire-feed
OK ! change the front panel module.
DISPLAY WORKS
!" check connectors J1, J2 and B9, B6
!" verify fuses F6 and F7 on regulation
card
!" if LED L5 doesn't go out: change the
regulation card
!" check connectors J1, J2 and B9,
B13, B15
!" verify fuse F7 on regulation card
!" check 1NUMA setting at PT 13
measure the motor power supply
voltage between PT1 and PT18
if no voltage ! change the
regulation card
if voltage approximately 30V
verify the motor
! !
! change
