Rocky Mountain Crane Service Logs
Operator lowered the block down, and then the hoist drive stopped. Could swing and trolley, but no hoist or lower function. Drive displayed SAFF. This fault is not in the Hup manual. The fault code app shows the following.
Had the operator verify that the CanOpen card was installed all the way. Had the operator switch ports on the CanOpen card, and the crane began working. Went to the crane and replaced the CanOpen card, and verified both ports are working
Hoist suddenly stops, and often will not restart until several attempts later. E68 code is displayed on CCS messages. It means that the KEB hoist drive releases the brake, and looks for the microswitch contact within 600ms (.6 seconds). If it does not, it will fault. Follow the steps below.
Hoist Brake Microswitch Adjustment
Also with this situation, the operator claimed the load would drop slightly. Was able to verify during startup, K405A (validated drive contactor) would close and K409M would energize allowing the brake to release, then the drive would shut down. Could recreate and U400X #29 was supplying +24VDC at startup to energize K409M. This comes directly from the drive, replace hoist frequency drive
Crane starts, but will not swing. the Green Square is flashing on bottom right of LMI. Swing drive has 3 fault codes, AFE1 AFE2 and FBA A Missing.
For AFE! and AFE2 see link.

Replace the memory stick, and had to force the K600M to stay active for complete download of the memory stick to the drive, and then restart crane. Crane swings and weathervanes properly.
Time shows 12:00AM and date shows 1/1/00. Fault (00024.00083) show SCM date and time incorrect.
Enter Mounting Menu (6). Enter System Date Menu (5) Reset date and time.
This is for older HUP’s that use 4 digit password.
When going into 2nd speed or faster, drive will fault. Trolley and swing still work at full speed.
DWFL displayed on Drive
The speed sensor is not reading the speed of the hoist drum. Need to make sure no dirt or grease is preventing the speed sensor from reading properly.
If everything is clean and clear, may be a bad speed sensor, you can change a parameter to ignore the speed sensor
After telescoping to the correct height, went to raise jib to 0 degrees, and all the drives would shut off. It would go down, but wouldn’t come up. Tomas said on “SOME” T85’s and “SOME” generators (pre-emission), the jib reatining winch can trip the phase detector. Jumper the 2 red wires together in 1 slot (11 & 14), and bypass phase detector. Once operation is complete move wires back.
Message E1514 indicates faulty display, however it could be that the CANbus system is open, and the display is the first component. Check the “T” which should be moved to the load pin . In this case the pins were bent on the Anemometer, and needed replaced.
Processor shows the following
Remote shows the following
Crane may think it is in “High Height” (H3) and 4 parts of line are selected (DM). In H3 (High Height) crane must be operated in 2 parts of line (SM), not enough line on hoist drum.
Make sure S917S is adjusted properly. It is the limit box on the end of the jib retaining motor.
If the switch is adjusted properly, and not activated (Normally Closed NC), check Fault Stack (3-4-1)
Most recent fault is that the CanOpen Module is not detected. Verify by checking Can Module Inputs on processor (3-9-1)
Check for RUN light on Can Module (U213X)
If the RUN light is not on check T131F (the +24VDC transformer) for power. If the DC OK light is not on, the transformer is not working.
Check Circuit Breaker Q133F to make sure transformer is being supplied 480 VAC. If breaker is tripped and cannot be reset, replace transformer.
If RUN light on, but flashing, it is not communicating with the processor. It will still show U213X as not detected. Disconnect H4, H5, H6 connectors on Can Hub (U237X)
These are the communication cables for the labeled drives and operate on the same CAN2 network. If the H3 disappears (may need to restart crane), plug each cable back in to determine which one (or more) may be the problem. The cable(s) may not be the only problem. It quit possibly could be the drive(s) as well.
Here is the condensed version of the expanded troubleshooting tree.
Issue
AC/Heat unit not working
Cause
The AC unit not working can be caused by multiple problems, follow the procedures in the resolution notes to find out what is wrong with the unit, or if it need replaced

Open the side door to access the crane display
Turn the switch that looks like an open book to the right.
This should be the display
Press the F1 button, and the following should be displayed
Press the F2 button
Press the F4 button and crane hours are displayed
Press F2 again and hours for each motion are displayed
