D4 Valve with Gen 2 easy-Drive Actuator
Value Bit
A memory fault has occurred and the actuator
32768 15 has been restored to factory defaults. Contact
your Emerson sales
A memory fault has occurred and the actuator
has been restored to factory defaults. Contact
32768 15
your Emerson sales office.
The actuator is unable to move to the
16384 14 commanded position and has stopped. Follow
troubleshooting guide in Help section to remedy.
The digital input has detected a closed contact
and the actuator has moved to its safe position.
8192 13
Check switch input device status.
The actuator has experienced a fatal error and
4096 12
shut down. Contact your Emerson sales office.
The analog values entered do not match the
analog signal level. Check analog signal value and
2048 11
value entered.
The valve travel distance is outside the
1024 10 acceptable range. Confirm valve type and that no
obstructions are present.
The analog values for open and close are less
than 4mA and previous values have been
512 9
maintained. Calibrate analog input with
differential >4mA.
256 8
Actuator was powered down during a move and
actual position may vary from commanded.
128 7
Recalibrate the valve span.
64 6 Span has been calibrated and actuator is ready.
32 5 Actuator is active and ready.
Control signal not present. Signal is <3mA,
16 4
timeout period exceeded (40051 or 40052).
