Bead guns not spraying
Paint guns and bead guns
If paint guns and bead guns are not working,
check paint guns first.
Bead tank air valve
Turn bead tank valve ON
Nozzles plugged
1. Turn off air pressure, see
Bead System
Pressure Relief
, page 9.
2. Remove nozzles and clean out any plug-
ging.
3. If paper or other debris is constantly plug-
ging nozzles use a filter when loading bead
tank (standard window screen works fine).
4. With nozzles removed, apply air to bead
tank. Spray beads into dry container.
5. Check if beads are wet. If beads are wet,
remove beads from bead tank and replace
with dry beads.
Solenoid valves
1. Go to diagnostic screen and check to see if
all solenoids are being recognized by Road-
Pak Skipline Controller (manual 3A5387).
2. Remove solenoid valve cover (19).
3. Check for broken wiring or a damaged plug
(see
Wiring Diagram
, page 39).
4. Check for 12V DC between red wire and
ground.
Programmable Skipline Controller
1. Go to diagnostic screen and make sure all
switches are properly working (manual
3A5387).
2. Inspect wiring and plugs for damage.
3. Replace any damaged wiring or plugs (man-
ual 3A5387).
Actual line length not matching
programmed line length
Out of calibration
1. Follow calibration in Programmable Skipline
Controller manual 3A5387.
2. Spray one or two test skips and measure
actual length. If actual length is longer than
programmed length, increase Paint Gun ON
delay. If actual length is shorter than pro-
grammed length, increase Paint Gun OFF
delay.
Actual cycle not matching pro-
grammed cycle
Out of calibration
Follow calibration procedure in Programmable
Skipline Controller manual 3A5387.
