Description
Input/Output / Digit. Feedback / Switch 2
Switch 2 Funct.
Position Info
Diagnostic State
Use this parameter to select whether the switch is to be used as a limit signal generator or for signaling
diagnostics messages.
• Position Info – Evaluate position
• Diagnostic State – Assess diagnosis status
Switch 2 Value
0 to 100%
Use this parameter to configure the position value as a limit signal generator. It is taken into account
when the ‘Switch 2 Funct.’ parameter is set to ‘Position Info’.
Switch 1 Logic
Active High
Active Low
Use this parameter to select the contact logic.
• Active High (active) = Output current I > 2.1 mA
• Active Low (active) = Output current I < 1.2 mA
Switch 1 Active
Fall below, Exceeding
Use this parameter to select the edge for activating the switch.
• Off
–
Deactivated
• Fall below – If down-scaled
• Exceeding – If up-scaled
Menu: Universal input
Menu / parameter
Value range
Description
Input/Output / Universal input
UI SP Value Max.
4.0 to 20.0 mA
Use this parameter to specify the upper current range limit for the universal input.
UI SP Value Min.
4.0 to 20.0 mA
Use this parameter to specify the lower current range limit for the universal input.
UI Damping
0 to 60 s
Use this parameter to set a damping value for the universal input signal.
UI Charact.
Linear, Custom
Use this parameter to select a function that adjusts the behavior of the positioner to the analog input
signal according to a predefined course. This linearizes the characteristic curves for the valves and
fittings and improves the behavior of the overall control loop.
• Linear
-
linear
• Custom - configurable by user
The user-configurable characteristic curve cannot be generated and saved in the device locally, however;
this can only be done via a PC with the appropriate configuration program (DTM / EDD).
UI Out Value Min
0.0 to 30000
Use this parameter to define which value is assigned to the minimum universal input signal ‘UI SP Value
Min.’.
UI Out Value Max
0.0 to 30000
Use this parameter to define which value is assigned to the maximum universal input signal ‘UI SP Value
Max.’.
