Air Flow Re-Zero Procedure
Perform this procedure if the iControl spray gun control screens are indicating pattern air
flow when a spray gun is off and no air is actually flowing. This procedure re-zeros the
pump control cards to eliminate false air flow indications.
Before performing a re-zero procedure:
• Make sure the air pressure being supplied to the pump cabinet is higher than the
minimum 5.86 bar (85 psi).
• Each pump circuit board in the pump cabinet controls two pumps and the pattern air
for two spray guns. Make sure no air is flowing through the pumps, around the pump
control manifold gaskets, or from around any of the solenoid valves on the manifold.
Re-zeroing boards when leaks are present in the control manifolds will result in
additional errors.
Re-Zero Procedure
See Figure 4-2. For each pump board that is being re-zeroed:
1. Disconnect the pattern air tubing controlled by the pump board from the output fittings
on the rear panel of the pump cabinet.
2. Plug the output fittings.
3. Record the board number and address settings of SW1 for each pump board.
4. Set each address switch to zero.
5.
Turn off the power to the pump cabinet, wait five seconds, then turn the power back
on.
6. Press and hold the TEST button on each pump board until the red fault light turns on.
Release the TEST button and wait for the red fault light to turn off.
7. Move the SW1 address switches back to their original positions.
8.
Turn off the power to the pump cabinet, wait five seconds, then turn the power back
on.
9. Remove the plugs from the pattern air output fittings and re-connect the pattern air
tubing.
10. At the iControl console, check each spray gun control screen that was previously
indicating air flow when the spray gun was off. No air flow should be indicated.
