Controller will not operate spray nozzle.
— Ensure that there is proper uid pressure supplied to the nozzle.
— Ensure that system is recognizing your trigger input. This is a common problem. If remote trigger/sensor is being
used and buon on the setup screen is set to “local”, the system cannot be recognized, the system trigger needs
to be set to something other than “local”. The inverse is also true, if the system is being triggered o the HMI
screen, the trigger opon must be set to “local”. Make sure your sensor is NPN design if you are using your own
sensor.
)
Ensure that the trigger mode is set to Local, DI2 or DI1+ DI2.
)
Navigate to the diagnosc screen.
)
Acvate the main trigger source (object sensor or equivalent): DI2 on diagnosc screen should go from a value of
0 to a value of 1 when the trigger device is acvated.
- If this does not occur, then ensure that the trigger device is properly wired.
- If problem sll occurs, then consult the manufacturer’s manual for the trigger device.
4) If trigger mode is DI1+ DI2, acvate the auxiliary trigger: DI1 on diagnosc screen should go from a value of 0 to a
value of 1 when the trigger device is acvated.
- If this does not occur, then ensure that the trigger device is properly wired.
- If problem sll occurs, then consult the manufacturer’s manual for the trigger device.
For electrically actuated spray nozzles:
)
Check that the nozzle cable is properly installed on both ends with no damage to the cable.
)
Set duty cycle to 100% from main screen and aempt to trigger again.
- If the nozzle acvates you may have selected a duty cycle too low or, max frequency too high for the nozzle you
are using.
- If the problem persists have a qualied electrical technician, ensure that there is 24 VDC on the nozzle cable
when the system is triggered.
For pneumacally actuated spray nozzles:
— Ensure that there is a minimum of 45 psi (3.1 bar) of air pressure on the main air input to the system and that the
main air valve is in the “on” posion.
— Check air supply.
)
Ensure that the valve cable is connected to the main output on the controller.
)
Remove Cylinder air tube from the outside port of the system.
)
Trigger the system to see if air comes out of the port.
)
If air comes out there is an issue with the cylinder on your nozzle. Contact your local Spray Specialist for
informaon on repairing or replacing your nozzle.
- If no air comes out, contact your local Spray Specialist by calling 1-800-95-SPRAY (1-800-957-7729) or call 1-866-
321-2250 to order a replacement air valve.
