When operator would stop swinging, the Slew Drive would shut off just before or just after the brake would set. NO active faults, but fault history showed code 00011.10002 Transition 4.
Verified DIIL input to slew drive.
Per Refik, changed Parameter 21.01 (21 – Start/stop mode .01 – Start mode) in drive from “Automatic” to “Constant Time”

This is similar to the service post found here:
However in this instance, isolating the Slew Drive by disconnecting hoist drive and trolley drive from the CAN system did not help. Checked for 60ohms on the CAN Hi and CAN Lo . This should confirm that the jumpers in both of the erection jumper plugs are there and correct. Found CANOpen card was not operating correctly.
Unplugged and plugged back in the CANOpen card and plug. Unplug and replug the memory stick back in. No change. Replace memory stick and drive came back up on line.
We were trouble shooting Remote and wanted to verify that Processor was looking for High powered anttenna
Go go screen 3221 and RSSI and it should read 0%
Here is a shot of the screen with the KK plug jumpered with dummy plug
RSSI reading 100%
Had a customer that was loosing remote function while on the job and had full battery and full signal. It would lose signal and go to the Potain Screen
We tried lots of different things and eventually ended up changing the channel on the remote. If you change the channel on the remote you must also change the dip switches on the high powered antenna. See post about that.
Please note that it is possible to just switch groups and still be on the same channel which does nothing. Changing the group does not necessarily mean that you change the channel. For example channel 3 is both apart of group 1 and group 3.
To change the channel on the remote
Remote off
Estop down
Hold 2 part 4 part button next to screen Turn on remote
Customer complaint was that the crane would not connect to the remote. It was found the U230X Processor display wasn’t on, but the light shining on the processor was on. A voltage reading of 50V was taken at the J1/2 and continuity reading was taken at J1/1. It was noted that K100A wasn’t energized. A voltage reading at J12/5 was taken and found a reading of 0Volts
The U230X has an internal fail safe that if there is something wrong with the start sequence it will not power on. In this instance all outgoing connections were removed until only the J1 Connection was left connected to the processor. The crane was powered on and the processor powered up showing information on the display. One by one each J connection was added until the processor would not power on. It was found that the J12 connection was the offending connection. The 24V connection at J12/5 was removed at the processor and and the crane processor powered on. The crane was once again powered down and a continuity reading was taken from the J12/5 wire to each J12 connection. It was found that the J12/5 was making contact to the J12/1, J12/3, and chassis ground. The customer inspected the KK plug for a connection error and it was found the wiring to the KK plug was compromised internally. As a temporary fix to allow the operator to continue to work a jumper wire was ran from J12/5 to the A1 connection on the K100A. The crane operates as it should. Replacement of the KK plug wiring should be taken in this instance.
This video shows how to set the dip switches on the antenna booster/high gain receiver. This will set the channel and group to match the remote. Video Link (don’t share link outside of RMC) Receiver code to set the dip switch to the correct positions
Voltage is reading 488 volts. It’s too much voltage. Need to reprogram hoist drive per service bulletin.TJF Service Bulletin
Trolley drive shuts off and fault is 00009.33153 Trolleying Frequency Converter: A.buS.
A.buS is the communication cable for drives and computer. There has been a CAN bus fault in excess of 96 times.
Disconnect green wire, on X6D-3. Service ticket started.
