401 Flow valve not detected
or bad
F1
See Figure 4-2. When the solenoid is not energized, the
resistance of the solenoid is checked by the system.
These faults are generated if no resistance is detected,
or the correct resistance is not detected. Check the
proportional valve wiring connections. Check the
solenoid operation. Replace the valve if the solenoid is
bad.
402 Atomize valve not
detected or bad
F2
403 Auxiliary solenoid valve
not detected or bad
F3
404 Flow airflow low F4
Air flow is less than commanded value.
Air flow setting may be too high for the system to
achieve. Do not set above 3.5 SCFM.
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. If the fault goes
away, clean or replace the pump venturi nozzle or throat.
Disconnect the air tubing from the iControl console. If
the fault goes away, then the air tubing is too long or the
tubing diameter is too large.
If more than one module reports the same fault, check
the console air supply pressure. The pressure must be
above 85 psi. Check the tubing supplying air to the iFlow
module for blockage.
