3. Pump remains on as long as object remains in front of photo-eye.
4. When object is no longer in front of photo-eye delay timer is started~ standard is 15 seconds (adjustable
on PLC if needed). (This timer’s purpose is to give enough time for the vehicle to pull past the photo-eye
and all the way through the spray bar before the pump shuts off. If the photo-eye senses another object,
IE another vehicle it will reset.)
5. After delay timer is up pump shuts off.
6. After pump shuts off there is a short delay and solenoid closes.
