Type of application
· Note: Section 7.8 contains details on the on/off valve.
h0 Type of application
No, [YES], ESC
No
Control valve
YES On/off valve
Depending on the adjusted type of application, the positioner re-
sponds differently in automatic mode and there are differences in
the diagnostic functions. See section 3.4.
h1 Operating point
0.0 to [100.0] % valve
position, ESC
Valve position if set point w > Operating point limit (Code 49 - h5)
h2 Fail-safe action limit
0.0 to 20.0 % [12.5 %]
of the set point, ESC
Limit of the set point w
A limit violation causes the valve to move to the fail-safe position.
h3 Lower limit to start test
[25.0 % of the set
point]
If the set point is between Lower limit to start test (25 %) and Fail-
safe action limit (Code 49 - h2), the valve remains in its last valid
position.
If the set point remains between Lower limit to start test (25 %) and
Upper limit to start test (50 %) for six seconds, a partial stroke
starts. After the partial stroke test is completed, the valve moves
back to the last valid position.
h4 Upper limit to start
test
[50.0 % of the set
point]
If the set point is between Operating point limit and Upper limit to
start test (50 %), the valve remains in its last valid position.
If the set point remains between Lower limit to start test (25 %) and
Upper limit to start test (50 %) for six seconds, a partial stroke
starts. After the partial stroke test is completed, the valve moves
back to the last valid position.
h5 Operating point limit
55.0 to 100.0 %,
[75.0 %] of the set
point, ESC
Limit of the set point w
A limit violation causes the valve to move to the Operating point
(Code 49 - h1).
