CorrectionCauseProblem
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 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 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 system. Refer to Photoeye, Encoder,
and Conveyor Interlock Troubleshooting on
page 4-32.
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 Operator
Interface manual.
Check for scanner remote node
communication failure on the Network Node
Status screen and Node Configuration
screens. Refer to Remote I/O 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 In/Out Positioner 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.
