In/Out Positioner Troubleshooting
Use the fault messages on the Alarm screen along with this table to
diagnose and correct in/out positioner 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 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 indicates 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.

reducer.
If the motor is not rotating, check the motor circuit protection, motor
wiring, VFD, and motor control circuits.
