♦ Proper operation of the pressure switch.
♦ Replace control board (9).

3.4.3 - Led (L) flashing = start button pressed during the power source start-up.

See par. 3.3.3.

When the central adapter protection is missing, this stops the power source with red led (S) lit.
This is reset automatically when the protection is correctly positioned in its slot.
CENTRAL ADAPTER PROTECTION TEST.
Control board (9), connector J4, terminals 1 and 2 = 0 Vac with protection engaged, 24 Vac
approximately, with protection disengaged.
♦ Check the wiring between reed switch (14) of the central adapter (12) protection
and J4 on control board (9).
♦ Check correct assembly of the torch fitting protection, and especially that the
magnet in the protective hood is positioned close to the reed when the hood is
inserted.
♦ Replace reed (14).
♦ Replace control board (9).

3.4.5 - Led (S) flashing = reed contact (26) closed upon power source start-up.

If the reed contact (26) on power board (20) is found closed upon start-up, the power source
remains blocked, without delivering current and with the led (S) flashing.
To restore proper operation, shut off and restart the power source after first removing the
cause that closed the reed contact (26).
To analyze the problem, carry out the TRANSFER ARC SWITCHING TEST, par. 3.3.9.
