Got a 2-stop front opening only DMC1 with a selector having a problem.

History:

Car was intermittently getting people stuck in the down direction soon after leaving the floor, around the same spot. Nowhere close to door locks though, and out of both cam zones (switches mounted on the car). I checked all the switches first, along with obvious things like cleaning door locks and checking hate switch, DCL and DOL. Slide guides, magnets are good. No luck. Still got someone stuck.

We replaced all 3 selector boards. Ran the car constantly for an hour. It got someone stuck again the next day. Same place. Put the laptop on it as it was stuck. Selector error 6. DZR reed reading true not in leveling zone. That's the only fault in the car. It happened multiple times, several different times while I was riding.

Tried to set the car up from scratch with a cold start (bad idea in hindsight, I know), run a hoistway scan again. Took a couple attempts but it took and everything reads normal.
Selector read level rdy. CLC is on SCA. No faults anywhere.

Here's where we're at. Car will run from 1 to 2 via tool car call registry, stop at floor level, doors won't open. It'll relevel on its own, cycle the doors if you open the 1st floor hall door. If you put in a 1 call though, it won't latch. It's reversed if you're in the car though. Hit the 1 button and it'll go to 1 and cycle the doors, but it won't latch a 2 call. Again, no faults. Looking at the bit parity and DZ inputs, it's reading the floors and DZ properly, the PI changes, etc. Hall calls don't work.

We're at a loss at this point. Swapped the CLC and learned everything from scratch again. Same issue. What could this be?

It's set up for a 2 landing elevator (parameter 2 is 2, #52 is set at 2, #56 is set at 2), and again, it'll correctly complete a hoistway scan, and the doors will learn, and I've saved both of settings.

I would check guide shoes possible car shifting enough to interrupt the gate SW.

Bad connections or traveling cable issues as well. If it's around the same spot check to see if you have a tear in the traveling cable. I've seen worn spots on traveling cables cause intermittent problems. Best of luck

double check parameters 18,31,32 if thats won't do it, go thru every parameter and verify. maybe a car call lockout parameter, how are you giving it a car call thru the tool? I've seen the car call option, on the laptop version, but have yet to find software that will accept a car call from the tool. as far as the DZR fault there is a little reed switch on the selector assy that causes this problem did you replace that, you may need to after you get this problem solved. sure sounds like a parameter problem, you may need to also go thru every clc variable and make sure they are in correct state. maybe you will find a clue there.

CLC adjustment 52 and 56 should be set to 3.

Garth is right, those should be 3. Those Params are not in the older software that does not support 84 & 85 CLC adjustments for door disco & placing calls.

On your first issue of leaving the floor and trapping someone along with a 006. I guarantee that is the DZR reed switch.

good call guys, if you look closely at the parameter listing, for 52 and 56, it does say in the table floors served,, 2 which would be a value of 2, but this would only be for the 2nd floor, floors served 1 and 2, would be a value of 3. missed that one. also if you look closely at the factory preset value, there are 2 values with asterisks next to them if it is a dmc1-A, factory preset would be 003 which if you did not change when you started, would have probably saved you a headache. thats a good one, guess you have to pay close attention to the details.

And you won't be able to do a door scan if you are at a floor that is not valid by those parameters. That got me good one time trying to recover from a dead battery in the middle of the night.

Wow, really? I'll give it a look on Monday. I've set cars up before from scratch and do not remember having to set 52/56 to 3. Maybe I've only set up older software by coincidence.

I'll report back ASAP.

i must have only came across older software on the dmc, i have tried giving various jobs over the years, car calls from the tool, and nothing. I probably gave up a little to easily. I always thought about that, the option is there on the laptop version, so there must be a job i can give car calls. ill have to be more diligent and try it on every dmc i work on. keep us posted dan

Yep. That was it. After changing out the selector boards and learning the hoistway, it took off fine. Good catch. Thanks.

Well, crap. The sucker ran fine for over a month, and just this morning tripped that same fault. Just once. Reset and it works great. Selector fault 06. No other faults in the controller, besides the CLC selector monitoring fault (025, I think). All 3 selector boards have been changed. New clc with different chips. Good hoistway scan. Nothing wrong with the limit switches on visual inspection.

Check for issues with the mechanical switches mounted on the switch tree. They use solid wires and they tend to break.

006 fault is almost always the DZR reed switch in the selector.
