Problem Possible Cause Corrective Action
Auto mode is selected,
homing has completed,
but no auto positioning
response from in/out
positioner
Auto hold action has
been applied to the in/
out positioner.
The in/out positioner is forced to the Retract position (refer to in/
out positioner configuration setting).
This is a normal and temporary occurrence when the iControl 2
system does not know the status of the parts on the conveyor
between the in/out positioner scanner and the in/out positioner.
This condition occurs when the iControl 2 console is powered up
or rebooted and part tracking (shift register) information is lost.
Auto positioning will commence when parts identified by the in/
out positioner scanners arrive at the in/out positioner.
Manual positioning is allowed during this period.
Booth interlock has
opened (booth exhaust
fan shut down).
The booth exhaust fan has been turned off. The in/out positioner
moves to the Park position (refer to in/out positioner configuration
settings) if the Auto mode is selected.
The in/out positioners can be operated manually while the booth
fan is off.
In/Out Positioner
scanner not responding
to parts passing by on
the conveyor.
Conveyor encoder not sending pulses to the iControl 2
system. Refer to Photoeye, Encoder, and Conveyor Interlock
Troubleshooting on page 4-30.
In/Out Positioner scanners not detecting parts:
Check scanner input values on the Input Status screen. Refer
to the Monitoring Operation section of the iControl 2 Operator
Interface manual.
Check for scanner remote node communication failure on the
Network Node Status screen and Node Configuration screens.
Refer to Ethernet Network Troubleshooting in this section.
Check for electrical power at the scanner controllers.
Check for a voltage signal, 0−10 Vdc = length of scanner (0
= maximum), from the scanner controller to the analog input
module. Refer to the Analog Scanner Junction Box drawings in
this manual.
If a voltage signal is read at the analog input module, and there
is no problem with the Ethernet network connections to the
controller node, then replace the analog input module.
In/Out Positioner preset
set to Fixed.
Normal operating scenario. Position change will only occur when
a new part appears at the in/out positioner.
