EMERGENCY operation

STOP
CLOSE
OPEN
Approach EMCY pos.
For the setting Immediately active:
The actuator can start immediately when switching on!
Risk of personal injuries or damage to the valve.
Ensure that the EMERGENCY signal is present when switching on.
Should the actuator start unexpectedly: Immediately set selector switch to pos-
ition 0 (OFF).
Customer settings M0041
EMCY behaviour M0198
EMCY failure source M0591
Default value: I/O interface
Setting values:
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.
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.
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:
EMERGENCY behaviour is active in the operation modes: Remote Remote II Fieldbus
EMERGENCY behaviour is active in the operation modes: Remote, Remote II,
Fieldbus, Local, Service
In the operation mode Off (selector switch position 0), no emergency operation is
performed.
The EMERGENCY operation determines which action is executed by the actuator
once the EMERGENCY behaviour is initiated.
