Problem
The air flow switch is
indicating unexpected
atomizing air flow.
The system timed out
without reaching the
user-specified volume
of solvent for a purge.
The solvent flow
switch is indicating
unexpected solvent
flow.
Potlife time has expired
before the system has
moved the required
amount of material
(potlife volume) through
the mixed material line.
The system timed out
before the mix fill cycle
loaded the gun with
mixed material.
Cause
Air flow switch is stuck
in flow position.
Leak downstream in air
line or fitting.
Air supply pressure
fluctuation.
Solvent flow switch not
working.
Solvent flow is too low
to actuate the solvent
switch.
Gun is not triggered.
Mix manifold was not
set to flush position,
blocking solvent flow to
the spray gun.
Cause
Solvent flow switch is
stuck in flow position.
There is a leak through
the solvent cutoff valve.
Purge process was not
completed.
Solvent supply shut off
or empty.
Mix manifold not set to
spray position.
Spray gun was not
triggered.
Restrictions in mixer,
manifold, or spray gun.
Solution
Clean or replace switch.
Check for leaks and
tighten fittings.
Eliminate pressure
fluctuations.
Replace switch.
Increase solvent
pressure to drive a
high purge flow rate
Operator must continue
flushing for configured
time, until the booth
control indicates purge
is completed.
Set manifold to flush
position.
Solution
Clean or replace switch.
Check for leaks and
repair valve.
Make sure purge
process is completed.
Verify solvent supply
is available and on,
supply valves are open.
Set manifold to spray.
Allow flow through gun
during fill process until
the fill complete LED
stops flashing.
Fix restrictions.
