9.3.3. Failure source (failure reason) for an EMERGENCY operation: set
Customer settings M0041
EMCY behaviour M0198
EMCY source M0591
Default value: I/O interface
Setting values:
I/O interface
The EMERGENCY signal is present as binary signal (standard: +24 V DC) at a digital
input. If this voltage (i. e. the signal) is no longer present, the EMERGENCY behaviour
is initiated.
Fieldbus interface
The EMERGENCY signal is sent as fieldbus command. If the command is no longer
present, the EMERGENCY behaviour is initiated.
I/O or fieldbus
If the fieldbus command or the binary signal is no longer present, the EMERGENCY
behaviour is initiated.
Active interface
If active interface fails, the EMERGENCY behaviour is initiated; e.g. when changing
the command source the failure source for the EMERGENCY signal also fails.
9.3.4. Operation mode for EMERGENCY behaviour
The EMERGENCY behaviour can be activated for the operation modes Remote
and/or Local
Customer settings M0041
EMCY behaviour M0198
EMCY operation mode M0202
Default value: Remote only
Setting values:
Remote only
EMERGENCY behaviour is active in the operation modes: Remote, Remote II,
Fieldbus
Remote and local
EMERGENCY behaviour is active in the operation modes: Remote, Remote II,
Fieldbus, Local, Service
Information
In the operation mode Off (selector switch position 0), no emergency operation is
executed.
9.3.5. EMERGENCY operation
The EMERGENCY operation determines which action is executed by the actuator
once the EMERGENCY behaviour is initiated.
Customer settings M0041
EMCY behaviour M0198
EMCY operation M0204
Default value: STOP
Setting values:
STOP
The actuator stops in the current position.
CLOSE
The actuator runs to end position CLOSED.
OPEN
The actuator runs to end position OPEN.
Approach EMCY pos.
The actuator runs to the specified position.
9.3.6. EMERGENCY position
If the Approach EMCY pos. EMERGENCY operation is set, the actuator runs to the
indicated EMERGENCY position.
Required user level: Specialist (4) or higher.
