Thank you for the reply. I do not turn the elevator back on, I have waited for the repair tech to come. In the end, he just turns it off and back on and only then does it operate. It is on the first floor everytime, but it's the only elevator and I think that is simply because the last person rides it down.

Is it a relay controller? Could we get a copy of the wiring diagram to trace the circuit related to re-opening of doors. I believe the wiring diagram is your property and is not subject to IP rights of OTIS. Once we have the wiring diagram; we may be able to offer a solution.

I agree elmcannic, i’ve had a few issues in the past where levelling speed was set incorrectly and would time out on low oil timer on a relevel More than once had I found that stupid F/S adjuster drift towards S when the three allen screws backed off just enough. Older valve as well as newer. Doing service work, who’d ever thought to check valve hardware? It’s like checking vic bolts…who does that? Until you’ve got a drip.

Hi Volunteer 19. If the lift works correctly after reset by switching off the power and switching it on, most probably it has nothing to do with the hydraulic system, but is related to the door system. Has the technician disabled relevelling? 1. Maybe after standing all night the piston is sinking and the lift is slipping past the door zone sensor. And if this happens, the door won't open when a call is registered at the first floor. But technically it should answer other floor calls. Have you checked calling the lift from the upper floors when this happens? 2. Or maybe after some time period the door circuit is timing off and is not coming on when a call is registered.
I think it is point 1, and when power is switched off and on, the lift travels to the floor to reset its count and reenters the doorzone again to make the doors operate.Since you say that the lift works fine the whole day, I suspect it is a sinking/relevelling disabled problem.
If this is the case let us know and we can suggest corrective action.

Hi Volunteer 19 The service chap has disabled relevelling. This is why when a lift halts for a long time at a floor, the piston sinks, the lift leaves the door zone and since it is out of DZ, when a call is registered, without DZ on, the door will not open on this floor. This is why when you called the lift from the 3rd floor, the lift stopped in the DZ and the door opened. For the lift doors to open, the DZ signal must be active, and if the lift sinks it leaves the DZ hence the doors won't open as the circuit path is broken when it is out of DZ.
When you observe this happening next time, after calling the lift from another floor and doors open, return to the floor where the door was not opening with a lobby call. If it opens, then 100% relevelling is disabled by the elevator technician. Cool ways of surreptitiously forcing you to modernize the lift.
Your lift is good.No need for upgrading.
Slap a legal case on the maintenance company or raise a complaint with the consumer protection society.
