The system does not spray. 1. The system is not in Spray
mode.
2. The isolation fluid pump is
empty and there is no material
to spray.
3. The fluid pressure is too low
or zero.
4. The paint trigger signal is not
being recognized.
1. Change to Spray mode.
2. Give the system time to fill
before trying to paint.
3. Increase the gun fluid pressure
on the Home screen or Preset
screen.
4. Be sure the paint trigger input
is getting at least 70 psi. If
this does not correct the issue,
check the pressure switch
and wiring in the electronics
control panel.
