No by-pass of torque profile. In EMERGENCY operation, the actuator operates into
the EMERGENCY position following the pre-set speed profile.

Delay time for EMERGENCY operation
An EMERGENCY operation is only performed once the delay time has expired.
Consequently, a short-term signal failure will not have an impact on the process and
will not immediately initiate an EMERGENCY operation.

Enable local controls
Application
●
Protection against unauthorised operation via local controls
●
Protection against unauthorised parameter setting via local controls
Properties
The selector switch functions LOCAL and/or OFF may be enabled or disabled.
Enable/disable local controls via fieldbus commands
For control via fieldbus interface, the command for enabling the local controls is done
via fieldbus command
Fieldb. enable LOCAL
.
Switching behaviour:
●
Fieldb. enable LOCAL
= 1 = enable:
Operation via local controls enabled
●
Fieldb. enable LOCAL
= 0 = disabled:
Operation via local controls disabled
Information
In the event of loss of fieldbus communication, the local controls will be disabled
since no enable signal is present.
If operation commands are not transmitted via fieldbus commands, but via <Additional
inputs> or an additional <Parallel interface>, a digital input has to be available and
configured to enable/disable the local controls.
