11 Configuration
11.1 Configuration principle explained
The SEZ220 signal converter comes with a number of preconfigured function
blocks. See the configuration diagram below. They comprise:
Configuration diagram,
contents
•
Inputs (input identifier, input function).
•
Function blocks MIN-MAX-AVR, ENTHALPY and 2X-INV.
Planning engineers use the configuration diagram to draw connections between
individual input and output functions (or their internal signals) and the assigned
terminals.

Physical inputs:
Designations
•
X
universal (for analog signals only in the SEZ220).
Physical outputs:
•
Y
DC 0...10 V
The following rules and properties apply to inputs:
Use of inputs Xx
•
Multiple use of inputs is possible.
•
Fault indication for inputs is active only if the input was connected prior to
commissioning.
•
All related settings change when you change an input identifier.
Order:
Configuration
procedure
•
Basic configuration (APPL ID) first, then extra configuration (CONF).
•
Input identifiers first, then function blocks.
Possible wiring:
•
From function block to input: "x" to "x".
•
From function block to output terminal: Analog "Y" to "Y".
The following applies to outputs:
Use of outputs Yx
•
Each output terminal can be used only once.
