Reading/values
Description
P16
Switching threshold of
software limit contact 2
–20 to 120 % [98 %]
Software limit 2 is displayed or can be changed in relation to the
operating range (steps of 0.5 %).
The contact switches to the responded state (Code
P14
) when the
value
exceeds
the limit.
P17
Software limit contact
test
Executable test function for the software limit contacts 1 and 2
To start the test, keep
pressed for 3 s. Select
SLS1
to start the
test for software limit contact 1 or
SLS2
software limit contact 2.
Press
to confirm. The selected contact is switched five times.
P18
Position transmitter
[>>]/<>
Setting the direction of action of the position transmitter:
The direction of action indicates the assignment between travel/
angle position and output signal of the position transmitter based
on the CLOSED position.
The operating range of the valve is represented by as a 4 to
20 mA current signal. Values exceeding or falling below the limits
2.4 and 21.6 mA can be indicated.
If the positioner is not powered (signal <3.8 mA), the output signal
is <1.4 mA or 3.8 mA (when the positioner is not initialized).
P19
Fault indication function
[NO]/HIGH/LOW
The output signal of the position transmitter is issued independent-
ly from the valve position and can be set to indicate a fault as fol-
lows:
NO
: no signal
HIGH
: signal = 21.6 ± 0.1 mA
LOW
: signal = 2.4 ± 0.1 mA
P20
Position transmitter test
–10.0 to 110.0 %
Executable test function for the position transmitter:
Values from –10.0 to +110.0 % (based on the operating range)
can be entered in steps of 0.5 %.
To start the test, keep
pressed for 3 s, select the percentage
and confirm.
P21
Reading of set point w
When the positioner has been initialized:
Displays the external set point in 0 to 100 % corresponding to 4 to
20 mA. Press
to read the internally adjusted set point in the
positioner (adjusted set point in 0 to 100 % according to the set
-
tings in Code
P7
and
P8
).
When the positioner has not been initialized:
Displays external set point in 0 to 100 % according to the
4-20 mA signal.
