Well,what I have here is a reversing contactor,compact design for frieght elevator.
There is a up and down with a push button emer. stop.
My problem is when I engage the contactors manually,pushing in up or down contactor,the jam relay included,works fine.But,using the push button,up or down,it basically chatters like a tommy gun.As I said before engaging it manually operates fine,push in the contactors and the memory holds in place,just with the push buttons
it chatters,along with the jam relay.
What would cause this,a bad coil on the reversing contactor?Or the jam relay?Any comments or opinions would be apperciated.
