Determine volume flow
With this parameter the user can set how the
volume flow displayed is determined.
"Line pressure" setting
The volume flow will be calculated with the gradient
of the line pressure, on which the GD Connect 12
is regulating.
"Volume flow x" setting
The volume flow will be measured with a volume
flow meter, which is connected either to the analog
input AI-2 of the GD Connect 12 or to an analog
input of an extension module.
Timer control
The various timer control channels can be set here.
The current date and time can also be set in this menu.
Profiles
The various profile parameter settings can be
programmed here
In a profile the following parameters can be set:
Max./Min. pressure warning
These values are limits which trigger warning
signals.
Max./min. pressure
Pressure range within which the GD Connect 12
regulates the line pressure.
Receiver volume
Volume of the receiver into which the compressors
pump the compressed air. The volume of the pipes
is not included.
Compressor priorities
In a profile each compressor can be set to an
individual priority.
Events / Statistics
Here the various statistics counters and event lists can
be reset or deleted.
Inputs/Outputs
Here the inputs and outputs can be assigned to various
functions.

No use
Activate profile 1 / 2 / .. / 12
Warning Dryer 1..4

In addition, two further parameters are programmable
for the digitial inputs to each function:
A delay, which avoids, that the appropriate
message is indicated to early.
The condition of the digital input, which indicates
the programmed message (input open or closed).
