I have a miprom 21 2 car group. When one of the cars is at certain floors and a hall call is registered the elevator will not respond. I have replaced the output board. When the car is registered I get my input light but the output light just flashes and doesn’t stay on. I also have the laptop from Kone and have ran the test on the output board and can watch the lights come on and hear the relays latch. Any help is appreciated.
