EMERGENCY operation:
EMERGENCY operation can be triggered in
REMOTE mode via
■
Binary input EMERGENCY, or
■
Fieldbus telegram or in case of
■
Wire break of control source.
8�4�1 EMERGENCY input
Normally Closed (NC)
Active for 0 V DC signal.
Normally Open (NO)
Active for 24/48 V DC signal.
Set to active high in the factory.
8�4�2 EMERGENCY speed
During EMERGENCY operation, EMERGENCY
position is approached at EMERGENCY speed.
= EMERGENCY speed in CLOSE direction
= EMERGENCY speed in OPEN direction
Parameterization within the speed range, refer to rating plate

8�4 Safety related parameters
The present chapter describes
■
the parameters for EMERGENCY operation (EMERGENCY input, EMERGENCY speed, EMER-
GENCY position) and
■
Possible actuator behavior on interruption of the control signal.
The sequence of the description of the individual parameters corresponds to the menu structure,
refer to illustration.
The procedure for changing the parameter values in the 'Safety' menu is identical to the procedure
in the 'DCS’ menu, refer to „8.3.2 Operation sequence: Changing the parameters in the ‘Control
system’ menu“ on page 67.
