Asked for picture of the display.  Note “E”rror code 553.  Look up error code 553 in file labeled “Diagnostic messages for 81K.

 

You can break this down by the identification codes at the end of circuit diagrams, but also find this code specifically in manual under “Safety device “Emergency – Stop”

K600M contactor was not energizing

When attempting to swing crane shutters but does not move

Crane will not swing at start up, but will kick out of weathervane.  Manually lift swing brake and attempt swing again, and crane will swing normally, however will not brake normally.

Look for +20VDC at V100F, and verified.  Look for +20VDC at K600M #7 and verified.  Found no voltage at K600M #8.  Although contactor was energized, contacts were not closed.  Replace K600M.

**Note** this was specifically on a Hup 32-27 which only has 1 swing motor.  Condition may be different with 2 swing motors on Hup 40-30

Top Zone WON’T Activate.

While Programming the CCS for Top Zone on Submenu (66) the crane will not accept the 10 digit Activation code. And will not change from (Zone not activated) to (Zone activated). The crane doesn’t know its serial number.  You need to go to Submenu (60 Mounting then to Serial) then put in the serial number.  Once you put the serial number in you need to go back to the Top Zone programming in the CCS and follow the steps in reprogramming the Top Zone.

Top Zone on a HUP

To activate Top Zone go to page 5-171 in your operators manual and follow the steps, to be able to set your Zones.  After  activating Top Zone in the CCS, you need to go in to teachin-program on your remote and set your degree point. Then you should be able to create your Zones.

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”
