Application Modes
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The application mode may be configured in the unit (refer to the Configuration Manual 37940 for more infor-
mation). This is only possible in code level 2. The most important features and differences of the three applica-
tion modes are illustrated in the following section. A description of the functions that are possible during each
application mode can be found in the configuration manual (manual 37940).
Util-Util Application Mode
This application mode has the following characteristics:
• The ATS controller monitors two mains sources and transfers the load to the secondary source in
case the primary source fails
• The ATS controller operates as Master controller
Util-Gen Application Mode
This application mode has the following characteristics:
• The ATS controller monitors a mains sources and a generator source and transfers the load to the
generator source in case the mains source fails
• The ATS controller operates as Master controller
This application mode has the following characteristics:
• The ATS controller monitors two generator sources and transfers the load to the other source in
case the regular source fails
• The ATS controller operates as Slave controller
• This application is not a stand-alone application and always combined with another ATS control-
ler in Util-Gen application mode, which operates as Master controller (refer to the Application
Manual 37942 for more information)
Engine operation special cases
In Util-Gen application mode and Gen-Gen application mode the ATS starts and stops an engine. Starting and
stopping is controlled by the state machine described above. However, in some rare situations the start/stop is af-
fected by the breaker state. These are
• If a breaker cannot be closed to a generator source (indicated by a corresponding alarm), then the engine
shall not run, it shall either not start or do a stop after cooldown
• If a breaker is connected to a generator source and cannot be opened (indicated by a corresponding alarm),
the engine shall continue to run.
• If a breaker closing to a generator source is inhibited, and the breaker is not already closed, the engine shall
not run or do a stop after cooldown.
