I'm trying to perform a hoistway scan. It's a 2 stop and all hoistway switches have been checked physically. The selectors led stays on while running up the hoistway and about 3" from floor level goes out with a 62 selector fault while the car passes the top floor and stops 1 5/8" above the floor on the limit. The Main and Aux sensors have been checked and deemed good? Any ideas? What does "pulse count in wrong direction" really mean?

Hey there, try to check if lower limit open , that happen to me.

pulse count in wrong direction means that the phase A and the Phase B selector pulses are not coming on in the appropriate order. the selector knows which way the car is traveling, by the order of the pulses. could be a missing pulse, etc. in your case the 62 fault is probably because the car is somehow stopping the setup procedure, due to a input it does not like, like the lower limit opening as cucuvator indicates, or something like a lock opening, is stopping the car in flight, which stops the setup procedure. use the tool to check the appropriate inputs from the switch tree and run the car up to the point you say the setup stops, and see if you see any of the inputs change state. this can sometimes be tough if the problem that is stopping the car is happening very quickly, as the information that is transmitted to the tool can be delayed a little. so if the input goes on and off quickly, you may not see it on the tool .you can have someone in the machine room watching the UP relays, and as you run the car up on inspect check if the up relays drop out and pick up quickly at the spot where you lose the led. this is will indicate that something is stopping the car which stops the setup. you might not even realize that the relay is coming on and off from the car. just a suggestion also, i have seen low oil sensors, wired in with the direction limits, or the starter. good luck

I have never seen a two stop DMC that was a selector board.Have never had to do a selector scan on a two stop just reset door timers

That's just it....Car never stops. It runs from BDL to TDL all the way. Locks are all jumped out and we are watching the selector light. Its normal and solid till 3" from the top floor while still moving and then goes out? Thanks for the description of pulse counts....That is something to look at!

After the scan are you getting a count? And you are using the gauge to set up your leveling and parity magnets? Also you've checked all your limits on your tree make sure they are picking/breaking. Not much going on the side of the car besides a 3inch mag, leveling mag, and 3-4 switches on the tree. If all that's good swap out the selector board try it again. What tool are you using? I have a fast, so I don't know much about the freedom tool.

this could be tough, i have had a couple tough setups, but usually the light will go out and abort the setup just as it leaves the bottom floor, usually because BDL was not set right. I have had one strange one that took nearly a day to figure out, the setup would abort about a inch or so after starting. turns out that the inspection input, IN was turning back on for just a second or so due to a shorted D22 diode on the relay board. the car would not drop the direction either. the only way i found it, was by using the laptop Dover DMC program which shows the input nemonics as blue or red for on or off, and i started looking at all the inputs, and noticed IN was flashing from blue to red briefly. as soon as it did the selector led would go out. might have to go down this route and check some key inputs and see if they are changing. good luck

Had a similar issue like you're having. it turns out one of the plugs on the selector board is faulty, not giving correct voltage. give a try

I should also state this elevator was hit with water. It was in a building that had a fire and got hit with alittle of it. I'm not using the world tool. It's a laptop based program like the fast tool. We have work through a few bad connections already...I have to check out your suggestions...Thanks!

Water damage being billable, I'd replace everything suspect and then some, to get the car running and avoid future headaches down the road. We do that to protect ourselves.

is this the orange cable thyssen program?

Water Damage you must change the switches on the switch tree, selector board, if the tape has any rust on it a whole new tape. Those switches in the switch tree are critical for those units. TSL1 does not make up it will sit at the first floor answer calls there, allow passengers, take car calls and the pump will even run but the car will not move unit the LOT gets it.

53 fault problem is in your switch tree UTS or TSL is not active but TDL is active. So it's in the switch tree.

It's an orange cord. It's also a 62 fault. All the boards and switches have been replaced. We are only contracted for the use of the tool...Just trying to come up with a solution for the other guy's!

Did you check the voltages of power supply? What voltage comes out. .

62 deals with the 2nd landing parity magnet. They prolly adjusted the leveling magnet and didn't move the 3inch. They need to get themselves a gauge and some info where the 2nd landing 3inch magnet goes.

Replaced the main and Aux reader board... no more 62 errors..Still not loading count..Selector board stays on with no heart beat? No selector fault now...CLC 35 Faults? I'm thinking CLC bad also...Reading parity bits and others variables when car is in middle of hatch? No magnet even close to it? Selector Board is a different board from water damage car so guessing it maybe OK?

The tape has been changed and magnets also. Power supply is new and good.

with all that water damage, clc probably bad. you can check the selector inputs by unplugging the communication cable from the selector that goes to the clc board. then plug into the db25 plug on the selector and check all the inputs, if you are still reading inputs when selector is not near any magnets, then you have problems with the selector assembly still. sounds like E-Mans advice maybe the best yet, replace all boards , and bill the customer. save yourself headaches down the road.

I would agree with you guy's...Never really got this deep in one...Kind of interesting if I wasn't so busy other places! I'll update when I get back there!
