Setting Switches Association
Switches Associations Concept
By default, switches outputs are autonomous.
Amethyst III lets you perform switches associations. In an assoc
iations,
the switches are positioned similarly, either all on their primary input or
all on their secondary input. Amethyst III then chooses the input (primary
or secondary in
put of the switches) that results in the least severity in the
association.
The primary input of a switch is always the one that has the lowest
number, whatever the order in which you added the inputs in the
configuration.
Switches Associations Configuration Principle
In the Switches association view you have to define for each association:
The switches you want to add
Whether the association may be disabled if it implies positioning a
switch with a
Redundancy
or
Main-spare
strategy on an input that is
in error although the other input’s state is better. In this case, each
switch will behave independently. This feature is called Disable
association on severity and requires that you define the level of error
that will disable the association (see example 4 below).
There are a few rules that should be followed:
In an association, you cannot mix switches with a
main-spare
strategy
and switches with a
redundancy
strategy. However, switches with a
manual
strategy can be mixed with another strategy.
In an association where the switch strategy is
main-spare
, the main
input must be the same in all switches, i.e. it must be either the first
primary or the secondary input of each switch.
Switches with a
manual
strategy do not contribute to the switching
decision, they follow the movement.
If you switch manually on one main-spare switch of the
association, this changes the main input of all main-spare
switches of the association
.
