Got a new hydro install with galaxy controller. Unit keeps going out of service, past 3 days. "Velocity errors", "Pulse count error". Moved pulse count sensor on the selector as close as possible to the tape. Changed velocity parameters, made UTS and DTS larger from 100-140. Car speed is 100 fpm. Customer is becoming very irritated. GAL. Tech support is nearly impossible to talk to. Waited on hold for 2 hrs., left messages, no call. Backs...anybody have any experience with these controllers? We heard they were good, this is our first experience with the Galaxy.
