Hello,

I have a 2 stop Kone MRL that was having various intermittent issues. We made a detailed list of all parameters, then sent in the ADON, CPU, and drive for testing, repair/refurbishment. ADON board was found to have a few bad relays which were changed. Everything else stayed the same. Upon re-installation, car would not move down on inspection, and we could not perform an ADON learn. Car jerks up whether I'm holding the up or down directional buttons. Double checked all parameters and found to be the same. Finally was able to move the car down by reversing the phasing. Weird thing is the car runs smooth in both directions when phasing is reversed, but won't move in the down direction at all with correct phasing. Double checked all connections, and even tried a second brand new ADON board with the same results. I'm newer to these machines so any help would be appreciated.

Update, with the reversed phasing I changed my 6-65 parameter from 2 to -2. It is now running correctly on inspection, but I keep logging an 0026 fault. The drive was just tested, anything else that can be causing this fault?

I'm assuming you probably did a LON download? It is accessed through menu 5-7-1. You wouldn't think the software versions would change just from getting the ADON repaired but you never know. I would try a LON download (5-7-1 and when it finishes its sequence reset the controller) and then do an ADON learn again. I believe 0026 is a drive fault but I don't have the codes in front of me. Was it faulting on 0026 before you reversed phasing? Also wouldn't hurt to verify the correct encoder and resolver connections.

Edit: Check if there is a parameter to reverse motor encoder feedback signal. If there is reverse it and see if that gets you anywhere.

Ok, so we were finally able to run a successful ADON learn and perform a shaft setup, and are no longer logging the 0026 fault. Instead, we keep logging 0071 (30 door zone missing), and no other faults. Every time the car is turned to automatic, it will travel to +/- 1/8 in. of floor level with no door operation. Checked all magnet positions and it appears to be good. Nothing in the hoistway has been touched while we've been working through these issues which is why this fault seems bizarre. CPU is showing 61:U and 61:N on along with 30 like my troubleshooting guide suggests. Don't know what else to try. Please help!

Kone machines can be so fickle sometimes. The lights on the cpu for 61:U, 61:N and 30 will actually go low when it has seen the magnet. I.E. when the door zone magnet is sensed the 30 light will go low on the cpu. It's counter-intuitive.

The sensors are the cigar shaped sensors right? Not the horseshoe oscillator?

If the 30 light on the cpu DOESEN'T go low when it is within door zone the signal is probably not reaching the cpu. If you suspect the sensor is good, you can trace signal to XB21 on the CCBN (car top board), and then to the cpu from there.
Drawing #E07

If the 30 light on the cpu DOES go low in the door zone then, well, faulting 0071 is a mystery. Maybe something went wrong during learn run or the sensor moved. Run it to the opposite terminal and see if it does it there too.

Did u look at the door operator?if the the state light is lit up then you need to do a door learn.

VTR Tech, thanks for the reply. The 30 light was going low in the door zone, so I decided to do another learn run. This time the car returned to normal operation. Seems like something from the previous learn run did not take. I ran the car for about 45 mins with no issues or faults, and returned to service only to get a call a few hours later of a shutdown. Now getting 0026(drive), followed by 0106. Car runs on reset but I'm sure will fault again. I'm starting to think the drive which we sent out and tested "good" is not so good.

I read you did a ADON learn and a shaft setup but did you do a decel learn as well? The 106 fault has something to do with the slow down resistors reaction to a deceleration of the car.

Norcan, I did not do a decel learn. Do you know the procedure for that?(Sorry new to this controller). The 0026 did come in first, I'm not sure if one is causing the other. Right now I just have to wait for it to shutdown again.

Just wanted to close this one out, call came in again on 12/7. I did decel learn like Norcan suggested, and returned car to service. Car has now run for 5 days fault free! Thank you to all who helped. Learned a lot about this controller and changing it's components. Pulling out the drive, CPU, and ADON all at once for testing definitely caused some issues even while saving all parameters. Special thanks to VTR Tech for helping us troubleshoot from the start.
