I’ve recently had trouble with a 3-stop DMC-I. If the car is at the bottom landing, and I give it an up call, the car will run up to the called floor with my high speed valve coil energized, but when my high speed valve coil drops out, my low speed valve coil does not pick up. The pump will continue running until controller times out. My valve coil is good, and I’ve traced the issue to an output from the main board (I wish I wrote down the terminal name) which is keeping my high speed relay picked, which is a problem since I know the relay needs to drop out for me to energize my low speed valve coil. If I remove this output wire when the high speed valve coil drops, the low speed valve coil will be energized and the car will level into the floor. Has anyone experienced this issue?
