Potain 27148 Encoder and fan on top of drive

Swing drive was getting encoder and fan error.  I tried to turn the encoder off but it didn’t work.  You are supposed to be able to just turn it off.  I then replaced encoder and cleared errors.

Potain 27148 Trolley losing 3rd speed

Went to jobsite to check out trolley.  They would lose 3rd speed every now and then and a lot of clicking noise in the panel.

Went to the erection aid it was changing between =0 and >30.  Sensor at cats head was not communicating properly.

Went to electrical and found that both B910n and B912n need to be on.  Put jumper from 44 to 40 and from 44 to 48. This made it equal zero in erection aid.

Will need to remove jumpers and fix before dismantle

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).
