Hi all,
I got a problem on this reach stacker. Telescopic boom not function, error code 55; faulty signal from regeneration sensor appear. Please advise me, how to solve this problem:
1. Telescopic boom, spreader does not function
2. Error code 55; Faulty signal from regeneration sensor

Thanks.

Hi Henry!
It is already 1 year late, but I would to ask:)
Did you try to calibrate this sensor through KDU menu in the cabin?
I think it was a reason.

Hi guys ,all that you talking about, i have gone through,so what i did was to reduce the rate of lowering speed by employing a resistor in circuit, got my self several resistors and came to an acceptable speed , hope i will not be sued by kalmar for redesigning there machine.

check if the manual lowering valves on the lift cylinders are corectly closed

Hi Henry, as the sensors are working correctly i would look at the wiring harness from the rear of the boom to the ECU as well as the connectors inbetween thesensors and the ECU, i hope this helps. Best regards Ian

Hi Ian the lights are coming on very well, this being npn sensors i have throughly checked them out against others and they seem to be fine so that is what is puzzling me, checked all possible angles too.Will be glad to hear from you.

Hi Henry, when you were checking the sensors are the small red lights coming on when the boom is near its maximum and minimum angles? if you can let me know i will be able to help

Hi Ian late august 2010you helped me out with the above reachstake regarding end position damping sensor , the problem is back again, i have tried all probable angles problem still persists, do still have more brighter ideas? thanks in advance regards
Henry

Hi Henry. happy to help. BR Ian

Hi Ian, sure i did look at both sensors and the result was positive,both sensors had got damaged as a result of swaying of the boom as my machine works on rough terrain.I changed both and all was ok.THANKS, nice to share ideas with you,
Henry.

Hi Henry
There are two sensors on the boom support at the rear of the machine along with a plate that is bolted to the outer boom section, the sensors read the position of the boom, one is sensor S22 which is the top sensor is used for damping the boom both up and down, i would have a look at this sensor and the plate which it reads off first, check the connections to the sensor as well. please let me know if you find anything wrong.

Thanks Ian, the serial number is T34107.0570. hope to hear from you soon.

Dear Henry, do you have the serial number of the machine? it will start with a T, if you can give me this information i should be able to assist with this problem.
regards
Ian
