INCIDENT N°7
DEFECT : HF ABSENT AT THE ARRESTER
State of LEDS and various devices Probable cause Control and remedies
CT1 engaged ð current supply ð 1 phase is missing check
external connections
R1 engaged ð fuse H.F. F6 ð check it
contactor above block H.F. ð H.F. assembly defective ð voltage at no-load condition
70 V at current supply H.F.,
terminals wires 68-69, if 70 V,
check H.F. assembly discharger
gap 2 x 0,6 mm
ð contact or connection of R1 ð check H.F. current supply and
go until the transformer TP1
CT and R1 do not engaged ð contactor ð if 24 V between 1 and 6 of
B33, if positive check wires
210 and 203 A, change it
LED 3 RAZ CIC = 1 ð wiring ð check 24 V between 1 and 6
of B33, if positive check wires
210 and 203 A (refer to
diagram)
ð connection B36 - B16 ð check with ohmmeter
ð cycle PCB ð check when G = 1 24 V
between 3 and 7 of B16
ð relay PCB ð change if 0 V between 5 and
10 of B36 when G = 0
CT1 engaged ð relay R1 ð if 24 V at relay terminals
between wires 220 and 203,
check it
R1 not engaged ð wiring or contact of R1 ð check wires 218, 220, 203 A
and the contact
LED 3 (RAZ CIC) = 1 ð relay PCB ð if 0 V between 9 of B33 and 9
of BB1, check PCB
LED 3 = 0
