Have you replaced your tape guides, and check your prox sensors. Make sure you haven't bent any pins on the plug on the tape reader board. Also check your switchs in the top of the hoistway. Or get a ims computer it will tell you whats wrong. Good luck.

I have replace the selector boards on about 75% of the jobs I have. They seem to be a weak point on these systems.

replace the relays throughout the MCD and MCE circuits, the original relays suck. common problem with a Tac20.

I agree replace the relays....garbage! You can also try taking the relays out and hitting them on a hard surface, i was told this will "reset the coil" it works sometime and will get you out of a jam until you can get new relays.

anytime otis takes on a tac20 we install a reliability kit which includes all new relays

E311>>><<< you know better, the tac 20 is one hell of a fine elevator system if you have the tools to work on them. they sure dispatch faster than any 211.
gs264>>><<< the big O calls them a first aid kit which contains silver tipped relays, both the 24v and the 110v to replace the originals which sucked right out of the box. it also contains new back-up batteries and some floppy disks to download the software on.

Don't know if this has anything to do with your issue but i am putting this out there because when i did work at TKE we ran across this on the TAC20 and the TAC50's....check all your connections that are factory installed, we had an issue in are area were the wire was behind the screw termainal! didn't start having problems untill almost a year after install. found this on power supplies and "aux" relays to the starter.

I know, I know....the Tac 20 is a fine unit. If I didnt have an LVM I would take the Tac 20 next 🙂
