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 Remote I/O
Network Troubleshooting on page 4-15 if the fault messages indicate a
communications problem (Watchdog fault or TCP/IP communications fault).
Each fault message displayed on the iControl 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. You can use the alarm relay to activate an external alarm.
Refer to Console Power Cable Connections in the Installation section for
more information.

Message Correction
1001 E-Stop Open In/out positioner or reciprocator E-Stop button pressed.
Determine why E-Stop button 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
S the anti-tip device is adjusted properly
S a carriage wheel bearing has not failed
S no obstructions are preventing motion.
Check the pulleys, belts, or other mechanical link connecting the
gear reducer to the 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 alarm screen.
