Description of operation Wiring
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.
Non-contact
Door Switch input
D1, D2,
D3, D4
All Non-contact Door Switch inputs connected to the
G9SX-NS@ must be ON as a required condition for
the safety outputs to be ON. Otherwise the safety
outputs cannot be in the ON state.
Feedback/reset
input
T31, T32,
T33
To set the safety outputs in the ON state, the ON state
signal must be input to T33. Otherwise the safety
outputs cannot be in the ON state.
Auto reset
To set the safety outputs in the ON state, the signal
input to T32 must change from the OFF state to the
ON state, and then to the OFF state. Otherwise the
safety outputs cannot be in the ON state.
Manual reset
Logical AND
connection input
T41, T42
A logical AND connection means that one unit (Unit
A) outputs a safety signal “a” to a subsequent 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.
Thereby the logic of the safety output of Unit B is
(AND). (An AND of inputs “a” and “b” is output.)
To set the safety outputs of the subsequent Unit in the
ON state, its logical AND connection preset switch
must be set to AND (enable) and the high signal must
be input to T41 of the subsequent unit.
Instantaneous
safety output
S14, S24
Turns ON/OFF according to the state of the safety
inputs, Non-contact Door Switch inputs, feedback/
reset inputs, and logical AND connection inputs.
During OFF-delay state, the Instantaneous safety
outputs are not able to turn ON.
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.
