6.3.5 Logic:
Each mainalarm area can be logically linked with the channel-own prealarm areas and
the mainalarm areas of the other channels. This results in a higher switch security and
ensures that temporal sequences are detected.
First of all the mainalarm area to
be defined is selected with the
timezone- and channel- buttons.
Afterwards the combination of the
additional areas can be done:
All edit fields, who stands in paral-
lel are together with the defined
area AND connected and consti-
tute a term.
Under it one more term can be
constituted.
If the conditions of one or both
terms are true, the defined area is
triggered.
The bar above the entry fields defines the condition ‚area is triggered„(bar is red), or
‚area is not triggered„(bar appears in grey).
In the example above the
mainarea
is only triggered,
-
if the green area
prealarm1
is triggered too ,
or
-
if the yellow area
prealarm3
is triggered too and the blue area
prealarm2
is not trig-
gered.
