Message Correction
2003 Motor Protector
Circuit protector limiting current to the in/out positioner or reciprocator motor has
failed.
Check mechanical components of in/out positioner for proper operation.
Lubricate, repair, or replace components as needed.
Check motor electrical circuit between protector and motor. Repair or replace
wiring, terminals, or motor control components as needed.
Reset circuit protector after corrections have been made.
2004 Motion Controller Fault
Motor speed controller “ready for operation” feedback signal has failed (if
applicable).
Check the status display on the motor speed controller for fault indications.
Status can only be displayed while power is applied. Cycling power to the
controller will generally reset the fault condition. Determine the probable cause
based on the controller fault status information.
Correct the problem causing the fault or replace the controller if necessary.
2005 Forward Contactor
Auxiliary contact on the motor forward contactor or similar control circuitry did
not operate when the in/out positioner was commanded to move forward.
Check control circuit and devices that command the motor for proper operation.
Repair or replace components as needed.
This fault must be reset from the iControl 2 alarm screen.
2006 Reverse Contactor Fault
Auxiliary contact on the motor reverse contactor or similar control circuitry did
not operate when the in/out positioner was commanded to move in reverse.
Check control circuit and devices that command the motor for proper operation.
Repair or replace components as needed.
This fault must be reset from the iControl 2 alarm screen.
The in/out positioner or reciprocator position feedback encoder is not putting out
pulses.
NOTE: If an encoder fails, an in/out positioner will move to the reverse limit
position. A reciprocator will stop.
Check all encoder mechanical and electrical connections.
Make sure the encoder is powered.
Check pulse output from the encoder. Replace encoder if necessary.
This fault must be reset from the iControl 2 alarm screen.
