Hey guys I’ve an escalator that been whooping my butt. This unit is an Montgomery 24V ES. This unit is intermittently shutting off. Sometimes it will run for an hr or sometimes 5min. When it shuts down it drops all voltage to the safety circuit. I check my power out of transformer when it faults outs and I’ve got 24V. When I move to the other side of the controller board at L3 (the start of my safety string) I have nothing. Anyone ever seen any thing like this? Thanks ahead of time for any input.
