iFlow Module Troubleshooting
NOTE: iFlow module output can be checked with the iFlow Air Flow
Verification Kit. Refer to Miscellaneous Kits in Parts for the kit part number.
Instructions are supplied with the kit.
CAUTION: Handle the verfication kit orifice carefully. Any damage to the
orifice will result inaccurate results.
Re-Zero Procedure
Perform this procedure if an iControl gun control screen indicates air flow
when the spray gun is not triggered on, or if a Flow Air or Atomizing Air Flow
High Fault (F6 or F7) appears on the Gun Control panel and the Fault
screen.
Before performing a re-zero procedure:
S Make sure the air pressure being supplied to the iControl console is
higher than the minimum 5.86 bar (85 psi).
S If the regulator supplying the module being tested is new, make sure it
has been calibrated for the correct pressure output. Use an iFlow air
flow verification kit and follow the instructions in the kit instruction sheet.
Refer to Miscellaneous Kits in Parts for the kit part number.
NOTE: The Air Flow Verification Kit instruction sheet can be
downloaded from http://emanuals.nordson.com/finishing,
Powder-US>iControl System.
S Make sure no air is leaking through the module output fittings or from
around the solenoid valves or proportional valves. Re-zeroing modules
with leaks will result in additional errors.
See Figure 4-2.
1. Disconnect the atomizing and flow air tubing from all four of the 8-mm
output ports and plug the ports with tube plugs.
2. Note the setting of address switch SW3, then set it to zero.
3. Press pushbutton switch SW1 to reset the module. The red LED should
be off.
4. Press and hold pushbutton switch SW2 for about two seconds, until the
red LED comes back on. Release the button. The LED will turn off
again in about seven seconds. The module is now re-zeroed.
5. Move address switch SW3 back to its original position.
6. Press pushbutton switch SW1 again. The red LED should shut off.
7. Remove the tube plugs from the output ports.
8. Check the Gun Control panel. With the spray gun off, the display should
show no air flow.
