ical AND Connection

A logical AND connection means that the G9SX outputs a safety
signal “a” to another G9SX, and that G9SX creates the logical AND of
safety signal “a” and safety signal “

b

.” The safety output of the

G9SX-NSA222-T0

@

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 Ro

b

ot 1

and Ro

b

ot 2, and it is equipped with Non-contact Door Switches and

an emergency stop

b

utton as safety measures. If the door to Ro

b

ot 2

is opened, only Ro

b

ot 2 is stopped (i.e., a partial stop). If the door to

Ro

b

ot 1 is opened or the emergency stop

b

utton is pressed,

b

oth

Ro

b

ot 1 and Ro

b

ot 2 stop (i.e., a complete stop).

The actual situation using a G9SX for this application is shown in this
example.
