D&s 5000 Problem

[aca carwash 2]

When the high pressure wash moves over the vehicle the power blast nozzles come on to clean the front and rear of the car. When it is in the rear of the car it starts to move up the rail before the the power blast nozzles come on. Any suggestions? Also the side spinners are coming on the same time the undercarraige comes on. Can these problems be related? Any ideas? check valves? solenoids?

Hi. Wish I had seen your post earlier. If you haven't gotten this fixed yet, its the timing or location of the gantry. Usually turn of breaker 6, do whatever to completely reset and let the gantry find itself again.
Hope this works,
Jack
