Potain Hup 40-30 (22131) – Does not allow for validation for mast locks

When towering up, mast locks are extended but the orange validation button does not appear. S934S does not close. Jumper 24 VDC to G5 and horn honks and validation button appears. Mast lock switches should look like this (folio 11):

Mast locks extended:
S933S 0 (open)
S934S 1 (closed

Mast locks retracted:
S933S 1(closed)
S934S 0 (open)

Will update once crane is down and switches are tested
