Garaventa Encoder issues - 10/25/23 02:10 AM
I believe the unit I'm working on is considered an Elvoron. We were having issues with the car losing the encoder count between landing 3 and 4 because of the wear in the guide shoes. We replaced guide shoes and overtightened the spring and the encoder wheel snapped off.
We replaced the encoder and reattached the wheel to the new one. We attempted to do a learn run without success. I brought elevator to bottom landing, ran it up past the IND magnet, brought it back down to floor level and pressed bottom 2 COP buttons and the PI changed from 0 to B. When I brought the car up to the 2nd landing floor level and held bottom 2 COP buttons the PI changed from B to 1.
Shouldn't it have changed from 0 to 1? I feel like it didn't properly register B. When I go to the 3rd landing floor level it doesn't change the PI when I hold the bottom 2 COP buttons. I spent like 2 hours doing this over and over without success. I am getting door zone at every floor stop.
I've noticed that the A and B leds for the encoder do not pulse while I'm running the car from the COP, they just stay lit. If the car is not running and I bounce up and down I can see the A and B pulse.
Not sure where to go from here
