AUMA ACV 01.2 User Manual

For the setting Immediately active:
Risk of immediate actuator operation when switching on!
Risk of personal injuries or damage to the valve.
→
Ensure that the signal set under parameter Source M0385 is present when
switching on.
→
If the actuator starts unexpectedly: Immediately turn selector switch to position
Local operation (LOCAL) or 0 (OFF).
9.2.2. Failure source (failure reason) for a failure operation: set
Customer settings M0041
Failure behaviour M0378
Source M0385
Default value: Active interface
Setting values:
Fieldbus interface
Failure behaviour is initiated in case of fieldbus communication loss.
I/O interface
The failure behaviour is initiated in case of setpoint loss (setpoint position, process
setpoint, actual process value).
The monitoring depends on the preset setpoint range, e.g.:
●
Setpoint = 4 – 20 mA, E1 lower than 3.7 mA = loss of signal
●
Setpoint = 10 – 20 mA, E1 lower than 9.7 mA = loss of signal
Information
●
For a setpoint range of 0 – 20 mA , monitoring is not possible.
●
Actuator controls will only respond to a setpoint signal loss, if a signal is present
at the MODE input, i.e. actuator controls are in operation mode Remote SET-
POINT (setpoint control).
Active interface
In case of fieldbus communication loss (if the fieldbus interface is active) or loss of
setpoints (if the I/O interface is active), the failure behaviour is initiated.
Possible failure reasons in case of fieldbus communication loss:
●
The connection to the master is interrupted.
●
The master goes into Clear state and sends:
- either global control telegrams with the content Clear
- or data telegrams of the length 0 (FailSafe mode).
9.2.3. Failure operation (reaction of the actuator) on loss of signal
The failure operation defines which action is executed by the actuator once the failure
behaviour is initiated.
Customer settings M0041
Failure behaviour M0378
Failure operation M0384
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 position
The actuator runs to the specified position. Conditions:
●
The function <Positioner> is activated.
●
Parameter Source M0385 is set to I/O interface
(for fieldbus control: Active interface)
