Hello, I am using a sevcon 4qpm controller and a PMG-132 perm motor for an e-car.
Problem: When I press the keyswitch the contactor closes immediately, no delay as before, and I am getting the fault: Drive 1 off, contactor 1 did not pulse during power on failsafe checks (failsafe circuit enabled).
How: There was a short circuit across the contactor during operation, the fuse on keyswitch blew as well.
Any recommendations or suggestions would be fantastic.
Thanks,
Martin
