AUMA ACV 01.2 User Manual

Setting values:
Active interface
Signals for triggering a PVST are sent via the active interface, i.e. changing the
command source also changes the failure source of the PVST.
I/O interface
Signals for triggering a PVST must be configured as binary signals (default: +24 V
DC) at a digital input.
Fieldbus interface
Signals for triggering a PVST must be enabled via PVST fieldbus command.
9.9.3. Operation mode for PVST
Required user level: Specialist (4) or higher.
Customer settings M0041
PVST M0852
PVST operation mode M0889
Default value: Stroke
Setting values:
Stroke
Stroke controlled PVST; operation across defined stroke (parameter PVST stroke)
within a defined time (parameter PVST monitoring). In this operation mode, the PVST
can be started in any valve position (even outside the end position).
End position test
Operating time controlled PVST; operation within a defined time (parameter PVST
operating time) after leaving an end position. In this operation mode, PVST can only
be started from one of the end positions.
9.9.4. Behaviour for PVST: define
The test can be performed in direction OPEN or direction CLOSE.
Customer settings M0041
PVST M0852
PVST behaviour M0853
Default value: OPEN
Setting values:
OPEN
Testing by operation in direction OPEN.
CLOSE
Testing by operation in direction CLOSE.
9.9.5. Partial stroke for PVST: set
During stroke controlled PVST execution (parameter PVST operation mode M0889
= Stroke), this parameter determines the partial stroke for a PVST.
Usually, the valve stroke amounts to 10 to 15 %.The amount of the partial stroke
depends on process requirements and the required diagnostic coverage rate.
Customer settings M0041
PVST M0852
PVST stroke M0854
Default value: 10.0 %
Setting range: 0.0 ... 100.0 %
9.9.6. PVST monitoring time: set
The actuator remains in the current position if the test could not be completed within
the pre-set time.
Customer settings M0041
PVST M0852
