Actuator only runs in direction OPEN or CLOSE while an operation com-
mand is issued. If the operation command is removed, the actuator stops.
OPEN+CLOSE (NO STOP)
Self-retaining without STOP:
A direct reversal of the direction of rotation without STOP command is pos-
sible.

Operation mode EMERGENCY
In an emergency, the actuator can be brought to a programmed EMER-
GENCY position by removing the EMERGENCY signal.
As the EMERGENCY signal works active low, 24 V DC must be present at
the EMERGENCY input while in the normal state (refer to wiring diagram).
An EMERGENCY operation is performed when the signal is interrupted
(0 V). During EMERGENCY operation the actuator does not perform any
operation commands.
After initiating an EMERGENCY operation (the EMERGENCY input is again
supplied with 24 V DC), the operation commands must be deleted and have
to be reapplied. This does not apply to operation commands being trans-
ferred via the 0/4 – 20 mA input or via fieldbus telegrams. They will immedi-
ately be executed again.
Information
For actuators equipped with a fieldbus interface, the EMERGENCY opera-
tion behaviour is only available if an I/O interface (fieldbus standard combi-
nation, page 66) or additional control inputs (page 63) are available.
