In/Out Positioner Troubleshooting
Use the fault messages on the Alarm screen with this table to diagnose and correct in/out
positioner or reciprocator problems. Refer to
Ethernet Network Troubleshooting
on page
4-14 if the fault messages indicate a communications problem (Watchdog fault or TCP/IP
communications fault).
Each fault message displayed on the iControl 2 screen is accompanied by a device
and number identifier. The identifier indicates the faulted machine (for example, IN/OUT
Positioner #1, Reciprocator #2). When the fault condition is corrected or cleared, the fault
message will indicate a returned-to-normal status.
For all in/out positioner faults, the alarm relay contacts open to signal an alarm condition.
Use the alarm relay to activate an external alarm. Refer to Console Power Cable
Connections in the Installation section for more information.

Message Meaning/Correction
1001 E-Stop Open
Determine why E-Stop button on system electrical control panel or a remote
panel was pressed and correct if necessary. Reset E-stop button when clear to
do so.
1002 Encoder Failure Fault
In/out positioner or reciprocator not moving. Mechanical, motor, or motor
controller failure.
Change in/out positioner or reciprocator operating mode to Manual and check
for proper forward and reverse (up and down) motion.
If only one direction of movement, check motor control circuits. If no motion,
check the following:
Check the positioner carriage to make sure it moves properly. Make sure that
• the anti-tip device is adjusted properly
• a carriage wheel bearing has not failed
• no obstructions are preventing motion.
Check the pulleys, belts, or other mechanical link connecting the gear reducer to
the spray gun moving carriage.
If the gear reducer is not rotating but the motor is, replace the reducer.
If the drive motor is not rotating, check the motor circuit protection, motor wiring,
motor controller, and motor control circuits.
This fault must be reset from the iControl 2 alarm screen.
