Analog input 1

Settings for analog input 1.
Details
The analog input 1 can be used as setpoint source.
The following settings are possible for the analog input:
Definition of the input range
•
Filter time for low-pass filters
•
Definition of the setting range (min/max range)
•
Dead band for eliminating the smallest signal levels
•
Manual I/O control

Definition of the input range
The analog input can be configured as voltage or current input. Internally, the signal is always
converted to a value in percent.
Definition of the setting range
The setting range results from the set min and max value for the respective mode.
Manual I/O control
The analog input can be overridden manually. After the function is activated, the actual values
are "frozen". Afterwards, each analog input can be overwritten manually.

Info
Definition of the input range.
PT1 time constant for low-pass filter.
• By the use of a low-pass filter, the impacts of noise to an analog signal
can be minimised.
• For an optimum filter effect, first the noise frequency has to be deter-
mined. The time constant then has to be set so that it equals the
reciprocal value of the double frequency.
