The flow setting may be too high for the system to achieve.
Maximum air flow is dependent on factors including air tubing
length, diameter, and pump type.
Switch to Classic Flow mode. This mode lets you set and
view actual flow-rate and atomizing air flow to help in
diagnosing the problem.
Check the tubing from the iFlow module to the powder pump
for kinks or blockage. Make sure the check valves are not
blocked. Disconnect the air tubing at the pump, clear the help blocked. Disconnect the air tubing at the pump, clear the help
codes, and trigger the gun. If the help code does not
reappear, clean or replace the pump venturi nozzle or throat.
Check the system air supply pressure. Pressure must be
above 5.86 bar (85 psi). Check the system filter and the
tubing from the filter to the power unit for kinks or blockage.
Refer to Section 5, Repair for procedures for using the iFlow
Air Flow Verification Kit to check the operation of the iFlow
module proportional valves and the output of the precision air
pressure regulator.
Switch to Classic Flow mode. This mode lets you set and
view actual flow-rate and atomizing air flow to help in
diagnosing the problem.
If the spray gun is triggered off when the help code appears,
disconnect the air tubing from the appropriate air output fitting
and plug the fitting. Clear the help codes. If the code does
not reappear then the proportional valve is stuck open. Refer
to Section 5, Repair for cleaning instructions.
If the spray gun is triggered on when the help code appears,
disconnect the air tubing from the appropriate output fitting
and set the flow to zero. If air is still flowing from the fitting
then plug the fitting and clear the help codes. If the code does p g g
not reoccur then the proportional valve is stuck open. Refer to t th th
Section 5, Repair for cleaning instructions.
If the help code reoccurs and the controller interface is
showing air flow, then check for leaks around the proportional
valves or transducers on the iFlow module.
If the help code persists, re-zero the module as described on
page 4-9.
Refer to Section 5, Repair for procedures for using the iFlow
Air Flow Verification Kit to check the operation of the iFlow
module proportional valves and the output of the precision air
pressure regulator.
This code appears if the gun was triggered on when the
interface was turned on. Turn off the interface, wait for several
seconds, then turn the interface back on, making sure the
spray gun is not triggered on. If the fault reoccurs, check for a
bad trigger switch.
Software version has been changed. This code will appear
after a software update. Clear the fault. It should not
reappear.
