Analogue inputs AI
AI1
Sign: Outdoor temp
Raw value: 18.4
Compensation:0.0
All analogue inputs are for Ni1000 or 0…10 V.
Input signals can be compensated e.g. for wiring resistance.
The raw value will show the actual, uncompensated input value.
If inputs have been assigned to pressure or flow control of fans, alternatively humidity

control, the following menus will appear:
SAF Pressure at
0V: 0.0 Pa
10V:500.0 Pa
Filter factor: 0.2
CO2 at
0V: 0.0 ppm
10V: 2000 ppm
Filter factor: 0.2
Set the parameter values that should correspond to the input signal levels
0 V and 10 V. The filter factor is the damping you want the program to work with in
order to reduce the influence of potential signal fluctuations on the sensor input. The
filter factor can be changed via the display or CASE flexotron® and is found after
’’analogue inputs’’ in ’’configuration’’. A new value is calculated using the following
formula:
New value = old value * filter raw value * (1 - filter factor)

Digital inputs DI

NO/NC: NO Signal:
Filter alarm 1
Status: No
To simplify adaptation to external functions, all digital inputs can be configured to be
either normally open, NO, or normally closed, NC.
The inputs are as standard normally open, i. e. if the input is closed, the function
connected to the input in flexotron®800 is activated.
Be careful when changing the input from NO to NC since some digital functions can be
configured to either NO or NC themselves. For example, you can choose if the Fire
alarm input should be activated when it is closed or opened. Therefore, there is a risk
that the signal is changed twice and the result is the opposite of the desired.
16.1.3
Universal inputs UI
On the largest hardware version, RDT828 there are universal inputs. These can
individually be configured as either analogue inputs or as digital inputs. When
configured as analogue inputs they can be bound to any of the analogue signals
described under Analogue signals.
When configured as digital inputs they can be bound to any of the digital signals
described under "Digital signals".
