AUMA TIGRON TR-M30X - Set Failure Source (Failure Reason) for a Failure Operation; Failure Operation (Reaction of the Actuator) on Loss of Signal

13.1.2. Set failure source (failure reason) for a failure operation
Customer settings M0041
Safety/EMCY parameters M2183
Source M2242
Default value: Active interface
Setting values:
Actuators with fieldbus or communication interface:
Fieldbus interface
Failure behaviour is initiated in case of fieldbus communication loss.
Actuators with fieldbus, communication or parallel interface:
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.
●
Integral controls will only respond to a setpoint signal loss, if a signal is present
at the MODE input, i.e. controls are in operation mode REMOTE SETPOINT
(setpoint control).
Actuators with fieldbus or communication interface:
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.
Actuators with Profibus DP or Profinet interface:
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)
Actuators with Modbus RTU or Modbus TCP/IP interface:
Possible failure reasons in case of fieldbus communication loss:
●
The connection to the master is interrupted.
●
The master sends no telegrams to the actuator controls.
●
The pre-set connection monitoring time is lower than the cycle time of the
Modbus communication.
13.1.3. 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
Safety/EMCY parameters M2183
Failure operation M2241
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 <Positioner> function is activated.
