System layout
The possible system layouts supported by the ATL900 are listed below. The following information is provided for each one:

The code used for selecting the layout type in the parameter setting P02.01 of the GENERAL menu (example: B: 2S-1T-PL)

An example of synoptic

A truth table

A description of a typical application.
Codes are used by way of examples in these synoptic to identify the single elements. Note that the text of these codes can be freely programmed to make them
correspond to the real system. In our examples, the code indicate the following:

SRCx = SOURCE power line Corresponding to the SRCx power lines.

BRKx = Line breaker. Corresponding to the BRKn breakers.

TBx = Tie Breaker.

LOADx = User load.

NPL = Non-Priority Load.

Two sources with only one load. Two sources with one tie breaker.
Load split between priority and non ‐ priority (NPL).
Source 2 may power only the priority load (LOAD).
Two sources with one tie breaker.
Two independent loads normally each powered
by its own source.
If one of the sources is lost, the other source
powers both loads.

If source SRC2 is lost, SRC1 may power both loads while SRC2 can only power
its own load.
Three sources with only one load.
