Hey guys, 4 car group,1 car runs non stop between bottom term.and next to top floor. Does not open doors or answer hall calls. It'll answer and cancel car calls and open doors but goes right back to problem. Didn't have much time to troubleshoot but checked for hung up relays,sel.switches,etc. any ideas?thanks

Sounds like the Car has some type of demand to run and is not seeing the slow downs from the selector, but it see the slow down for car calls. The slow downs for Hall and Car calls originate from different points on the Selector, I would look there closely.

Might be the card for the lev optals. if it's bad car will run from top to bottom forever.

Thanks guys,I'll try again tomorrow

Ended up being load weighed contact holding up BY. Understand why it wouldn't answer hall calls not sure why it was running nonstop? Thanks for the help guys.

Might have two things going on. Check you back contact on SE #3 sometimes will get a burr on it and fire OT which will run top to bottom.

not able to find posting with my particular issue so trying here...

Have 2 car bank Dover Composite with 2 issues, only really concerned with the one issue but describing both as they are dispatching issues and maybe related.
This is the smaller composite controllers with the plastic covered hall/car call relays mounted on the back side of controller and not IBM style front swing panel ones

Issue #1- Both elevs intermittently will answer same hall call...haven't spent much time on that one so not sure about any pattern, rhyme or reason.

Issue #2- If car #4 is not on 1st Fl.landing and car #5 IS AT 1st. Fl. landing and 1st Floor hall call is sealed car #5 which is sitting there idle will not respond to hall call, doors never open, other car #4 will also
not respond so 1st floor hall call stays sealed basically shutting down 1st floor operation.

- Car #5 has to be IDLE at 1st Floor landing for this to happen, if car is at any other floor it will come down and answer 1st Fl hall call

- I assume car #4 (dispatch car) recognizes that car #5 has been assigned to answer 1st Floor hall call so that is why it (car #4) stays put

- I have confirmed that both controller 1st Fl relays are pulled in.

- If I give car #5 a car call to leave 1st floor then other car #4 will come down to answer 1st floor hall call

- I have seen this condition and both generators go to sleep with 1st Fl hall call still sealed.

- I can use "CS" or "CR" relays to open doors and answer/cancel hall call

I suspect it's related to car #5 selector floor bar issues or relay back contacts in car #5 1st.Fl hall call circuit

any help would sure be appreciated, Thxs
