Reciprocator Troubleshooting
Use the fault messages on the Alarm screen with this table to diagnose and
correct 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 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 reciprocator 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.

Determine why E-Stop button was pressed and correct if
necessary. Reset E-stop button when clear to do so.
2002 Encoder Failure Fault Reciprocator not moving. Mechanical, motor, or motor VFD
failure.
Change reciprocator operating mode to Manual and check for
proper up and down motion.
If only one direction of movement, check motor control circuits.
If no motion, check the following:
Check the reciprocator carriage to make sure it moves
properly. Make sure that
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 carriage.
If the gear reducer is not rotating but the motor is, replace the
reducer.
If the motor is not rotating, check the motor circuit protection,
motor wiring, VFD, and motor control circuits.
This fault must be reset from the iControl alarm screen.
