INCIDENT N°2
DEFECT : TRIGGER = 1, NOTHING HAPPENS
State of LEDS and various devices Probable cause Control and remedies
L1 green signal lamp = 0 ð fuse F1 on front panel ð change it
L2 orange signal lamp = 0 ð ð
ventilator is working, no LED
lights up ð wiring cables 200, 201 cut ð check 24 V ~ between wires
200 and 201
L1 green signal lamp = 0 ð connector B35 on the relay ð check : 24 V ~ between 1 and
L2 orange signal lamp = 0 PCB 2 of B35, otherwise check
ventilator is working continuity of wires 200 A and
LED 5 (+ 15 CIR) = 1 201
LED 6 (- 15 CIR) = 1
LED 7 (+ 24 CIR) = 1
L2 orange signal lamp = 1

let the set cool down
L1 green signal lamp = 1 ð make sure that the ventilation
ð works, otherwise check fuse
F7
R31 relay on relay PCB should ð check connection of ventilator
increase by actionning selector I3 220 V ~ between W2 and
Arc/TIG otherwise, next case 100 of B1 if positive, check the
engine
ð WCU option ð check water passage and I3
position
ð wiring ð if 24 V between 9 of B33 and
ð ð 2 of B31, cut between 206

and 224 A
L2 orange signal lamp = 1 ð fuse F31 on the relay PCB ð check it
L1 green signal lamp = 1
no relay triggered
L2 orange signal lamp = 0
ð torch ð shunt the trigger terminals on
L1 green signal lamp = 1 front panel. If the cycle starts,
check the torch
relay R34 on relay PCB does not ð current supply of relay PCB ð if R31 on relay PCB does not
trigger trigger under I3 action (TIG arc
LED 2 (trigger CIC) = 0 selector) check current supply 24

terminals of B35 or 27 V 60 Hz
between 1 and 5 terminals of B35
ð relay PCB ð 24 V ~ between 9 terminals of
B33 (wires 224 A) and 4 of B31
(wires 222). Otherwise change
the PCB after having checked its
current supply
ð connection and filter PCB ð check wires 232, 230, 222 B,
224 A if 24 V between 222 B
and 224 A filter PCB and 0 V
232 and 230 change the PCB
L1 = 1 - L2 = 0 ð connections B36 - B16 ð check with ohmmeter
LED 2 (trigger CIC) = 0 ð ð
relay 34 triggered ð fuse F11 on cycle PCB ð check it
L2 = 0 - L1 = 1 ð cycle PCB ð change it if 0 V between 8 and
