Working on kone ecospace

Continuing to have problems with the door detectors or something else maybe even one of the boards. Started out with the rear door and is now doing the same thing on the front door, when the door shuts the red light on the detectors come on and the door reopens with nothing in the way. In the to box there is 1 board mounted on the side and it has a red lon fail led and blinks twice,the doors don't do it every time, does anyone know if lon fail light has anything to do with this. Thanks for the help in advance.

Try doing a learn trip on your doors,is your state light on or off?

As above. Press button on door board and open and close doors several times on inspection and see if led state changes.
If detectors are activating, the
Photocell led will be lit on LCE.

Photocell lights sometimes when the car is in motion, doors will not respond directly from the toc box open/close but will from the push button on the top of the door operator itself where the run/test toggle is. State light was not on but now is after the learn was done, don't know for how long because I have done the learn prior to this also.I noticed that the photocell led on the lce don't blink while the car is idle but the detectors led will blink.Also still have the lon fail led on?

State light shouldn't be orange,u have to do the learn till it goes off sometimes it takes multiple attempts as for Lon failure try doing a Lon download.I've had doors that just loose the learn out of the blue for some reason,should see photocell on CPU if it's blocked I believe.

Replace edges if you are sure there is no obstruction or alignment issues

State light is out and normally would just replace the detectors but why would it blink on the detectors led and not on the photocell led but does light the photocell led when there is a true obstruction , could the lon fail have anything to do with it?
