Power supply
input
A1, A2
Connect the power source to the A1 and A2
terminals.
Connect the power supply plus (24 VDC) to the A1 terminal.
Connect the power supply minus (GND) to the A2 terminal.
Safety input 1
T11, T12
To set the safety outputs in the ON state, the high
state signals must
b
e input to
b
oth safety input 1
and safety input 2. Otherwise the safety outputs
cannot
b
e in the ON state.
Corresponds to Safety

Safety input 2
T21, T22
Corresponds to Safety
Category

(Cross fault
detecting mode (for safety
inputs))
Non-contact
Door Switch
input
D1, D2,
D
3
, D4
All Non-contact Door Switch inputs connected to
the G9SX-NS must
b
e ON as a required condition
for the safety outputs to
b
e ON.
Otherwise the safety outputs cannot
b
e in the ON
state.

T

To set the safety outputs in the ON state, the ON
state signal must
b
e input to T
33
.
Otherwise the safety outputs cannot
b
e in the ON
state.
Auto reset
To set the safety outputs in the ON state, the signal
input to T
3
2 must change from the OFF state to the
ON state, and then to the OFF state. Otherwise the
safety outputs cannot
b
e in the ON state.
Manual reset
Logical AND
connection input
T41, T42,
T51, T52
A logical AND connection means that one unit (Unit
A) outputs a safety signal “a” to a su
b
sequent unit
(Unit B) and Unit B calculates the logical AND (i.e.,
outputs the AND) of the signal “a” and safety signal
“
b
”, which is input to Unit B.
There
b
y the logic of the safety output “
b
” is output.)
To set the safety outputs of the su
b
sequent Unit in
the ON state, its logical AND connection preset
switch must
b
e set to AND (ena
b
le) and the high
signal must
b
e input to T41 of the su
b
sequent unit.
Cross fault
detection input
Y1
Selects the mode for the failure detecting (cross
fault detecting) function for the safety inputs of
G9SX corresponding to the connection of the cross
fault detection input.
Keep Y1 open when using T11, T21. (Cross fault detecting
mode (for safety inputs))
Connect Y1 to 24 VDC when not using T11, T21. (Wiring
corresponding to category 2 or
3
, or when connecting safety
sensors)
Instantaneous
safety output
S14, S24
Turns ON/OFF according to the state of the safety
inputs, feed
b
ack/reset inputs, and logical AND
connection inputs.
During OFF-delay state, the Instantaneous safety
outputs are not a
b
le to turn ON.
Keep these outputs open when not used.
OFF-delayed
safety output
S44, S54
OFF-delayed safety outputs.
The OFF-delay time is set
b
y the OFF-delay preset
switch.
When the delay time is set to zero, these outputs
can
b
e used as non-delay outputs.
Keep these outputs open when not used.
Logical AND
connection
output
L1
Outputs a signal of the same logic and at the same
time as the instantaneous safety outputs.
Keep these outputs open when not used.
Auxiliary
monitor output
X1
Outputs a signal of the same logic and at the same
time as the instantaneous safety outputs.
Keep these outputs open when not used.
Auxiliary error
output
X2
Outputs when the error indicator is lit or flashing.
Keep these outputs open when not used.
