DEFAUT : H.F. PERMANENTE - INTENSITE RESTE AU MINI
Cause probable
ð F71 - F72
ð alimentation et connexion
ð liaison B34 - B74
ð carte régulation
ð carte relayage
ð carte relayage
ð liaison B36 - B16
ð liaison B75 - B15 (cycle

ð carte cycle
Probable cause
ð F71 - F72
ð current supply and connection
ð connection B34 - B74
ð control PCB
ð relay PCB
ð relay PCB
ð connection B36 - B16
ð connections B75 - B15
(control cycle)
ð cycle PCB
DEFAUT : INTENSITE RESTE AU MINI
Contrôles et remèdes
ð les changer. Si les LEDS 5 ou 6
ou 7 ne fonctionnent plus,
changer la carte
ð vérifier 2 x 17 V entre 5 et 4
puis 5 et 6 de B 74 fils 250 -
251 - 252
ð vérifier TA1 et connexion 24 V à
ces bornes fils 201 et 200 B
ð si R32 (carte relayage) en
soudage n'enclenche pas,
vérifier les connections B34 -
B74
ð bornes 5 et 6 de B74, vérifier 0
V quand I soudage, sinon
changer la carte
ð bornes 4 et 5 de B34, vérifier
24 V à vide, sinon changer la
carte
ð bornes 4 et 5 de B34, vérifier 24
V à vide, sinon changer la carte
ð vérifier à l'ohmmètre
ð vérifier à l'ohmmètre
ð changer si aucune cause
précédente
Control and remedies
ð change them. If LEDS 5 or 6 or 7
no longer work, change PCB
ð check 2 x 17 between 5 and 4
then 5 and 6 of B74 wires 250
-251 - 252
ð check TA1 and connection
24 V to those terminals wires 201
and 200 B
ð if R32 (relay PCB) in welding do
not engaged, check connections
B34 - B74
ð terminals 5 and 6 of B74, check
0 V when I welding, otherwise
change PCB
ð terminals 4 and 5 of B34, check
24 V no-load, otherwise change PCB
ð terminals 4 and 5 of B34, check
24 V no-load, otherwise change PCB
ð check with ohmmeter
ð check with ohmmeter
ð change if no other cause
