As I stated earlier I replaced the L relay and verified everything appears fine. However, I noticed that if the L relay is held up for one second longer, it allows the doors to open. I'm unsure about the specifics of Westinghouse coils, but I know they have various types with different resistances. I also don't see any timing circuit for the L relay, but I'm wondering if the resistance in the coil might be causing it to drop out a bit prematurely. I've never seen that be an issue though.
I’ve never encountered this issue when swapping coils that had a little different in their resistance on other controllers, but I’m curious if anyone else has experienced something similar with Westinghouse coils and varying resistances. My parts department matched the part number, which the new number is different from the original. I can’t imagine a slightly different resistance being the problem, if that's even the case. See the attached print for the L coil circuit, all contact are fine, L just needs to hold 1 second longer. If anyone has a suggestion please let me know, if not I may have to add a delay off timer.
Thanks
Love what I do, enjoy the challenge, the elevator industry has made me a much smarter man than I ever would have been.
