Further information about the air station can be
displayed by touching the "Info" key (see Fig. 5).
Here the information can be read but cannot be
changed.
Fig. 8 – Air station information
Overview timer control
The timer control programming is displayed here.
Each day of the week is represented by a horizontal bar
which is the same colour as the current profile displays.
Current profile
All parameters of the current profile can be displayed
here.
A profile is a set of parameters (i.e. pressure band and
compressor priorities) corresponding to different
operating requirements of the station.
Up to 12 profiles are definable and can be activated by
the timer control or a programmable digital input.
Events
Pressing this key displays a list of the last 50 events for
the air station.
This list includes all compressor events and any relating
to the air station, e.g. a fault in the GD Connect 12 line
pressure sensor.
The event list can be deleted in the "Adjustments GD
Connect 12" menu.
Measured values
The line pressure and volume flow values can be
shown here as diagrams.
Operating hours
The distribution of the compressor operating hours is
shown here rather than in the compressor information.
There are two types of operating hours:
Absolute operating hours
These are the total and loaded hours as listed in
the compressor controls.
Relative operating hours
These are the total and loaded hours since
a user-defined time.
This can be the time since the distribution of newly
added operating hours to individual compressors
the GD Connect 12, for example.
The relative operating hours can be reset in the
"Adjustments GD Connect 12" menu.
Statistics
Various statistical values since a user-defined time are
displayed here, e.g. the minimum and maximum line
pressures ever measured.
The statistical values can be reset in the “Adjustments
GD Connect 12” menu.
Software
The GD Connect 12 software versions are displayed
here.
Help
This gives the user access to various help topics, such
as wiring diagrams for compressor controls or how to
operate the GD Connect 12.
