Schindler 5500 error 709

Hi all, I have 4 Schindler 5500 units, 12 floors on my route, the only breakdowns I get come up with 1680, preceded by 709 error, easy reset but I want a more permanent solution, can be any floor, any time? Thought it might of been someone bouncing the belts but I have seen it on cctv from inside and nobody was in the car at the time and it’s never a stuck with passengers,Any suggestions?

709=
The safety circuit opened during a trip or a test. The safety circuit may have been interrupted only for a very short time. Check safety circuit and logs of other subsystems (total error log)
2 Cable of safety circuit signal broken or not connected Check wiring from control (ASxxx board) to frequency converter.

Check safety switches, maybe govenor tension switch is close?

Hi Heisenberg,





Is it possible to get this fault list With error descriptions???...


I also have a 5500 on my route.......
