Hello guys,
I am new to the forum, sorry if I brake any rules of it.
I am working on KONE Minispace elevator and have some issues:
- The elevator was running normally but suddenly failed. It was found the fuse F2 for the control line was burned. It appeared to be the brake module. After replacement elevator, start working in RDF only. If I switch in INSPECTION it just opens the brakes, and the car jumps up around 100-150 mm. If I put in NORMAL mode, the elevator tries to go to level, the board sees oscillators 61U/N and 30, and gives command to stop, but just before the brakes engage, the car is pulled up around 50mm, so it loses the signal from 61U and tries to relevel again. If I manually put the car on level, with 61U/N and 30 oscilators active, the car will stay steady and will be able to accept commands for going up/down.
I changed already the battery on top of the car, the LCECCB, LCEADO, BRAKE MODULE, oscillator 61U, LWD, and inverter, but I still cannot find the reason why it behaves like that.
Would appreciate any ideas or directions on what to look for.
