Vicario will only hoist in 1st speed
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
Liebherr Jib pin
Need to make sure you pull down on the cable that is attached to the jib release pin while folding up jib. It can get stuck and not slide properly and will bend plate. Which won’t latch properly.
Liebherr auxiliary motor went down.
When trying to fold the jib out it would stop and throw an error on the remote E 2651. Which means Torque limit motor reached. When using the motor it was putting out 11 to 15 amps before kicking out. A good motor at full speed puts out 5to 8 amps while working properly. You can find your amp pull right on the drive +k-T1. Replaced aux motor and was drawing 7 amps
All drives shut off, when raising jib after telescoping
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.
Crane will not move E1514 message – Liebherr 81K.1
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.
Reeving Impossible / Assistance Mode on Processor display
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.
Hup crane wont fold to weathervane
After service and teach-in of a Hup 32-27 The jib was required to be folded for weathervane. Went through the book to confirm the steps were completed in order and done correctly.
The crane would fold the jib tip but not the complete jib. A red x would appear when weathervane target was selected.
The image for the Trolley position if glanced at quickly is difficult to decern the correct trolley placement. 
Note: The trolley must not be in the transport position.
Trolley in, until the trolley is completely inside the first jib section. This will allow the jib to fold for weathervane.
AC not working in cab
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
Resolution
- Check the circuit breakers that control the AC and heat units
2. Check phase detector inside AC unit to be sure it has 2 lights
3. Replace AC controller to the left of seat
4. Check to see if the Condenser fan on the back of the cab runs when AC is selected, if not, check the fuses
5. Try using the “Defrost” setting and see if the AC turns on
6. Access AC unit and check to see if all the sensors are connected and working properly
7. If you cannot figure out why the AC unit is not running, order a new unit and replace it

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
