A memory fault has occurred and the actuator
has been restored to factory defaults. Contact
your Emerson sales office.
0x4000 0100 0000 0000 0000 Motor Assembly Stall 16384 14
The actuator is unable to move to the
commanded position and has stopped. Follow
troubleshooting guide in Help section to remedy.
0x2000 0010 0000 0000 0000 Discrete Input override mode active 8192 13
The digital input has detected a closed contact
and the actuator has moved to its safe position.
Check switch input device status.

The actuator has experienced a fatal error and
shut down. Contact your Emerson sales office.
0x0800 0000 1000 0000 0000
Analog Input calibration value not in expected
range
2048 11
The analog values entered do not match the
analog signal level. Check analog signal value and
value entered.
0x0400 0000 0100 0000 0000
Valve travel distance calibration not in legal
range
1024 10
The valve travel distance is outside the
acceptable range. Confirm valve type and that no
obstructions are present.
0x0200 0000 0010 0000 0000 Analog Input span calibration not in legal range 512 9
The analog values for open and close are less
than 4mA and previous values have been
maintained. Calibrate analog input with
differential >4mA.
0x0100 0000 0001 0000 0000 256 8
0x0080 0000 0000 1000 0000 Valve was shutdown while moving 128 7
Actuator was powered down during a move and
actual position may vary from commanded.
Recalibrate the valve span.
