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.

219 stuck on 99% moment

Crane won’t go to 100% moment and load.  Can’t change it from 99% to 100% on the display for your maximum moment and load.  Need to go to the CCT U246X and put in your tech code then go change the moment and load to 100% then you can go change it on the display in teach in and crane configuration. To access it on The CCT

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

  1. 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

Crane lost slew function AFE1 Code on slew drive

Crane lost slew function. AFE1 displayed permanently on screen. If cleared, drive would shut down. Checked voltage at XD24-2 24V connection on slew drive. Voltage was present but not 24V. Checked XD24-1 connection at slew drive Voltage was present but not 24V. Removed the XD24-2 wire are rechecked and voltage was 24V. Determined K600M Contactor was faulty.
If a new contactor isn’t available. K466M (motor preheat contactor) is the same and doesn’t use the 13/14 connections. This a great contactor to use to get the crane up and running.

3381 code on Slew Drive

According to ABB drive manual

Code: 3381

Fault: Output phase loss
Programmable fault: 31.19

Probable Cause: Motor phase loss
Motor circuit fault due to
missing motor connection (all
three phases are not
connected).

What to do:  Connect motor cable.

K600M contactor was not energizing

Transition 4

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”

Hoist safety brake: Kept open

02061.00048 Hoist safety brake Kept open

Problem:

This fault was a recurring fault in the fault history log. The fault would clear the active fault log when the crane was in use and only appear when the crane was turned off.  (Switched off from the remote or an Estop command input)

Solution:

Determine if the crane is fitted with optional “SAFETY BRAKE”  If fitted: follow directions in CCS Manual to correct the fault.

If not fitted, check the configuration of the crane and determine if the safety brake option is not active.

If active, De-select the option

and restart the crane.  Fault code with be removed.
