During erection, mast folds together but sensor S915S will not open and allow you to validate to move to the next screen. Disconnect G4 and the horn will honk. Reconnect after the next step.
Potain is aware and working on a fix.
Potain 972 (MA13) Drive Replacement
ATV 58 drives that were originally installed on the crane have been replaced with ATV (MGC) 31 drives. In the “kit” there are also additional blocks and a time delay module.
I was unable to fit the time delay module on the rail with the other contactors. I ended up placing it on the rail directly below the resistors (see image). Time delay module needs to be set for .300 ms ( referred to by Tomas as .30 ms). Open the clear door and set the range to .1 – 1 s and the dial to 3. When wiring time delay module, you’ll see it 2 separate places on the wiring schematic. It should have an input on #15 and (xx). On the bottom, should be the #18 (which should switch to +24V when the module is activated (when module is activated, there is a small green light on at the bottom right corner). The other bottom socket (xx) should by ground (noted as 0V in schematic).
The connector block to add to K800M contactor (trolley) is the larger of the 2. It needs #53 and #54 connected.
The smaller connector block mounts to K940M (hydraulic pump for erection)
Potain 27148 (T85A) Horn will not shut off
Image shows wire added to “jumper”, but just needed 1 wire removed.
After Dusty’s discussion with Tomas, Inductive detector for Mast Raising Control (B913N) has failed. Circuit is normally closed and setting off the horn. remove wire #11 or #61 in the G strip (folio 4/13 A-8).

Autec Remote Display Weight
To zero out weight on display, open receiver box in control panel. Switch rotary dial to 1. This should change display screen to set Dta. Dta is the minimum limit. Set to 0 with no load on the hook. Small buttons on receiver near rotary switch are + and -. Once it’s zero and, hold both buttons until the remote display says “result: success”. Dtb is the maximum limit and both need calibrated to be accurate on display. Dtb needs to be 50% of maximum load.
Liebherr Login Code
When logging into the diagnostic menu, code is (month + date) + (hour + minutes) example if it is 4/15 at 14:30…its (19) + (44) = 63 code will be 63 for one minute. Hit the “+” 63 times to get to correct code
