Air Flow Re-Zero Procedure
Perform this procedure if the iControl 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:
S
Make sure the air pressure being supplied to the pump cabinet is higher
than the minimum 5.86 bar (85 psi).
S
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 5 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.
