Interlock is active in operation modes:
The Interlock behaviour determines which selector switch functions (LOCAL, OFF)
require an additional enable signal.
Required user level: Specialist (4) or higher.
Customer settings M0041
Interlock M0664
Running dir. Interlock M0666
Default value: OPEN and CLOSE
Setting values:
The enable signal is only required for operation commands in direction OPEN.
The enable signal is only required for operation commands in direction CLOSE.
The enable signal is required for operation commands in directions OPEN and
CLOSE.
The Partial Valve Stroke Test (PVST) is used to check the actuator function. During
this test, the function of the valve is tested by means of partial opening or closing
within a defined period of time without interrupting the process. After successful
testing, integral controls operate the actuator to its initial position.
If the test was not successful, integral controls will generate the following signals:
PVST fault PVST abort. For monitoring the PVST, these signals must be evaluated
by a PLC.
Position transmitter in actuator.
If the actuator is in safe state (caused by the failure behaviour), the test will not
be executed.
The test can only be performed during OPEN - CLOSE control. For setpoint
control (modulating duty), a test cannot be performed.
Actuators with parallel interface: For the change-over, a digital input for the signal
Execute PVST has to be available and configured.
Execute PVST via fieldbus command
Actuators with fieldbus or communication interface: For control via fieldbus
interface, the tests are initiated via the PVST command.
Switching behaviour:
PVST = 0 (low active) = no test
PVST = 1 = test is initiated
If the test is not to be transmitted via a fieldbus command but using a binary signal,
(e.g. +24 V DC) via <Additional inputs> or via an additional <Parallel interface>, a
digital input has to be available and configured.
Configuration of digital input
Required user level: Specialist (4).
