HUP Not Hoisting UP

Got a call from a customer in Jackson crane not hoisting up

When into teach and shunt and it still would not Hoist up kept kicking out the drive

Had to reset the CCS with Shunt Pass

Then had to go in and reset Load PIN

To do this

Go to Main Load Pin Hit enter twice on ok to get a check mark

Do the same with redundant

Then turn off Breaker Q133 for CCS

Turn back on and then go back to load pin and number will show up below hit enter twice and do the same on redundant load pin

Turn off Breaker Q133 for CCS

Turn back on and double check both load pins read zero and proceed with teach in progress

BAM MOTHER FUCKERS!

Hoist function stops immediately after starting (Hup and Igo T85)

brF shows on the drive

CCS code (remote and panel) 00008 28944  “brake chopper”

Brake microswitch is out of adjustment.  Bottom lock nut backed off.  Readjust switch as per manual (click link below), test and operates as it should.

 

Hoist Brake Microswitch (S409S)

Igo T85 stopped hoisting as well, neither up or down.  brF on hoist drive.  Reset brake microswitch.

Brake Microswitch Adjustment

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
