DIGITAL INPUT
DI Function
DI Default SP
DI Logic
Selection of functions or states that are executed or adopted if the "digital input" has been
activated.
ALARM OUTPUT
ALARM LOGIC
DO ALARM MASK
Alarm Simulation
Use this parameter to configure the alarm output via which a general alarm can be issued.
Depending on the activated Namur classification group, it is also possible for the general alarm to
be issued as an alarm current.
ANALOG FEEDBACK
Analog Out Min.
Analog Out Max.
Feedb. Charact.
AO ALARM MASK
AO Simulation
The current valve position (or the "back-calculated valve flow characteristic", if this option is being
used) is fed back as a current signal via analog position feedback.
Depending on the activated Namur classification group, it is also possible for the general alarm to
be issued as an alarm current.
DIGIT. FEEDBACK
SWITCH 1
SW 1 MASK MAP
SWITCH 2
SW 2 MASK MAP
Digital feedback can be used to configure two limit switches which are able to report when a
value is reached or exceeded, via a current signal. Additionally, diagnostics bits can be output via
the second switch.

DI Default SP
0 … 100%
The position defined using this parameter is approached when the "digital input" function has
been set to "Hold User SP" and the digital input has been activated.
Use this parameter to configure the contact logic for activating the digital input.
IMPORTANT (NOTE)
For the following parameters, the contact logic is always "active low" or "off":
—
Safety Position
