Controller will not operate spray nozzle.
—
Ensure that there is proper fluid 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 button 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 off the HMI
screen, the trigger option 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 diagnostic screen.
)
Activate the main trigger source (object sensor or equivalent): DI2 on diagnostic screen should go from a value of
0 to a value of 1 when the trigger device is activated.
-
If this does not occur, then ensure that the trigger device is properly wired.
-
If problem still occurs, then consult the manufacturer
’
s manual for the trigger device.
4)
If trigger mode is DI1+ DI2, activate the auxiliary trigger: DI1 on diagnostic screen should go from a value of 0 to a
value of 1 when the trigger device is activated.
-
If this does not occur, then ensure that the trigger device is properly wired.
-
If problem still 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 attempt to trigger again.
-
If the nozzle activates 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 qualified electrical technician, ensure that there is 24 VDC on the nozzle cable
when the system is triggered.
For pneumatically 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
”
position.
—
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
information on repairing or replacing your nozzle.
