Corrective Action Possible Cause Problem
Color change cycle
started, gun
positioner stopped at
forward limit switch Oscillator not at bottom of stroke Oscillator must be at bottom of stroke
for spray guns to be in position for
gun blowoff. Blowoff will not start until
bottom of stroke sensor is on and
remains on.
Check oscillator position.
ColorMax not selected on iControl
gun positioner configuration
screen Check gun positioner configuration.
Oscillator not stopped Oscillator gets stop command from
gun positioner #1 control panel.
Check wiring and connections
between gun positioner control panel
and main system panel.
USA only -- Oscillator bottom of
stroke sensor not sending signal to
main system panel. Sensor detects
rotating lever arm. Make sure sensor
is positioned to detect arm and check
wiring and connections to sensor.
Reciprocator not at Park position Reciprocator must be at Park position
for spray guns to be in position for
gun blowoff. Blowoff will not start until
Park position is achieved.
Check reciprocator position. Make
sure Park position is configured
within stroke range. Refer to iControl
Operator Interface manual for
reciprocator configuration settings.
Color change cycle
started, blowoff air
does not turn on No air supply to solenoid valve or
pilot valve, failed valve, or bad
electrical connection Solenoid valve (typically located in
the main system panel) is activated
by signal from the gun positioner
control panel. Solenoid valve sends
air signal to large pilot valve that
provides air to the blowoff nozzles.
Make sure main system panel air
supply is on.
Check solenoid valve output. If
solenoid coil is energized but no air
flows from valve, replace valve.
Check air tubing to pilot valve.
Check pilot valve operation.
Check the wiring and connections
between the gun positioner panel and
main system panel.
