Parameters and possible parameter values
8 Parameters and possible parameter values
8�3 Parameters for the DCS
8�3�7 Control system – Analog input AI1
Setpoint at analog input 1 for positioner or pro-
cess controller setpoint or for speed setpoint.
Slope
Rising
Rising: 20 mA corresponds to 100 % OPEN,
refertog.2.
Falling
Falling: 20 mA corresponds to 0 % OPEN.
Range
4 – 20 mA
Detection of wire break is possible (live
zero).
0 – 20 mA
Detection of wire break is not possible (dead
zero).
8�3�8 Control system – Analog input AI2
Analog input AI2 is only displayed if the addi-
tional analog module is available. The setting of
the parameters is identical to 'Analog input AI1,
refer to previous chapter.
8�3�9 Control system– Binary outputs
All in all 8 signaling outputs are available for
the binary feedback signal of the actuator to the
control system. Each of these outputs can be
deactivated or assigned one of 21 status mes-
sages available, refer to menu overview on the
right.
Furthermore, the level of the feedback signal
can be determined: Normally Closed (NC) or
Normally Open (NO).
Normally Open (NO): Active for 24/48 V DC
signal.
Normally Closed (NC) Active for 0 V DC signal.
