Multiquip generator starts and dies immediately

After cranking the first time, the Overcrank and Overspeed lights come on.  When attempting to restart, only Overcrank and Overspeed lights come on, but the generator will not crank. Opening the control panel, can flip the switch Maintenance mode and generator starts, but will not shut off.  The 15 amp mini blade fuse behind the control panel is blown.

Crane will not accept a code and date shows 1/1/00 and clock showed 00:00

Tried entering the crane code, SCM code, and technician’s code into the crane cab display, but we crane would not accept the code.  CCT and SCM were not communicating, and because the date was incorrect, the crane display would not accept any codes.

Start by switching Q131F off and then back on.  Enter the SCM replacement code into CCT, and the go to Menu 2 and then to Advanced.  Enter New Device and verify serial number and date and time.  Switch Q131F off and back on again, and start crane.

If an incorrect code(s) have been attempted in the crane computer, it will get confused and will not accept any codes.

Auto wind on Hoist on T85

Auto wind on hoist while raising and lowering mast not working .

Did trouble shooting with Potain and used these screens to determine if signal was getting to processor and then to drive.
Also screen will show you how much weight on load line  while going up was consistent at around 800-1000 lbs  going down was around 0-250

We found brake disc on hoist was hanging up just enough to cause the issue.  Took apart Hoist brake and cleaned and anti seazed everything and all seems to be working now

Use videos for reference of what should be chaning on outputs when you start to raise the mast IMG_9049

Hoist safety brake: Kept open

02061.00048 Hoist safety brake Kept open

Problem:

This fault was a recurring fault in the fault history log. The fault would clear the active fault log when the crane was in use and only appear when the crane was turned off.  (Switched off from the remote or an Estop command input)

Solution:

Determine if the crane is fitted with optional “SAFETY BRAKE”  If fitted: follow directions in CCS Manual to correct the fault.

If not fitted, check the configuration of the crane and determine if the safety brake option is not active.

If active, De-select the option

and restart the crane.  Fault code with be removed.
