Logical AND Connection
● Example with G9SX-AD322-@
The logical AND connection means that the Basic Unit (or Advanced
Unit) outputs a safety signal “a” to an Advanced Unit, and the
Advanced Unit calculates the logical multiplication (AND) of the safety
signal “a” and safety signal “b.” The safety output of an Advanced Unit
with the logical AND connection shown in the following diagram is “a”
AND “b”.
This is illustrated using the application in the following diagram as an
example. The equipment here has two hazards identified as Robot 1
and Robot 2, and it is equipped with a safety door switch and an
emergency stop switch. You may have overall control where both
Robot 1 and Robot 2 are stopped every time the emergency stop
switch is pressed. You may also have partial control where only
Robot 1, which is closest to the door, is stopped when the door is
opened. In that case, Robot 2 will continue to operate.
The actual situation using a G9SX for this application is shown in this
example.
(Note: The logical AND setting on the Advanced Unit must be set to
AND (enabled).)
● Example with G9SX-ADA222-@
The Advanced Unit G9SX-ADA222-@ is equipped with two logical
AND connection inputs. Therefore, it is capable of receiving two
safety signals, each from different Advanced or Basic Units. As
shown in the diagram below, the output of Advanced Unit
G9SX-ADA222-@ will be “a” AND “b” AND “c”.
Connecting Expansion Units
• The G9SX-EX and G9SX-EX-T Expansion Units can be connected
to an Advanced Unit (G9SX-AD322-@/G9SX-ADA222-@) to
increase the number of safety outputs. (They cannot be connected
to a Basic Unit.)
• A maximum of five Expansion Units can be connected to one
Advanced Unit. This may be a combination of G9SX-EX
Instantaneous types and G9SX-EX-T OFF-delayed types.
• Remove the terminating connector from the receptacle on the
Advanced Unit and insert the Expansion Unit cable connector into
the receptacle. Insert the terminating connector into the receptacle
on the Expansion Unit at the very end (rightmost).
• When Expansion Units are connected to an Advanced Unit, make
sure that power is supplied to every Expansion Unit. (Refer to the
following diagram for actual Expansion Unit connection.)
