8. Extension module
41
Analog inputs
Programmable functions of the analog inputs:
No use
Line pressure 1..8
Volume flow 1..8
Temperature 1..8
Dew point 1..8
Note that a line pressure sensor that is connected to an
extension module cannot be used to regulate the line
pressure. Pressure regulation and subsequent
switching of the compressors can only be done from
sensors which are connected at analog inputs AI-1 or
AI-2 of the GD Connect 12.
For the connection of a volume flow meter applies:
Detection of the volume flow and subsequent switching
of the compressors can also be done from a sensor
which is connected to an analog input of an extension
module.
The values measured at the analog inputs of an
extension module can therefore only be used for
monitoring.
Either active or passive sensors can be connected to
the analog inputs. Jumpers J1 and J2 must be set
accordingly. An overview of the jumpers can be found in
the annex.
