Compact controller ER 2022S and ER 2022SA
8. Configuration
8.1 Analog inputs ”Inp”
Procedure
Apply two measurement points ((1), (3)), one after another, to the controller; they should
be as far apart as possible.
At these measurement points, enter the required display value (start value FtS, end value
FtE) in the controller. A reference instrument is most convenient for determining the
measured values M1 and M2.
Measurement conditions must remain stable during programming.
Programming
h Move to measurement point (1)
h Enter start value (2)
1
h Move to measurement point (3)
h Enter end value E (4)
1
If fine tuning is conducted without a reference instrument, the offset must be
taken in account when moving to measurement point (3).
To undo fine tuning the start and end values (EtS, FtE) must be programmed to the same
value. This automatically sets the start value to 0 and the end value to 1.
Any subsequent fine tuning will otherwise to be based on the corrected characteristic.
1.
If start value=0 or end value=1 is to be set, then the value must first be altered using I or D to enable
correction.
