G9SX-NSA222-T03-@
Signal name Terminal
name
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.
Safety input 1 T11, T12 To set the safety outputs in the ON state, the high state
signals must be input to both safety input 1 and safety
input 2. Otherwise the safety outputs cannot be in the
ON state.
Safety input 2 T21, T22
Non-contact Door D1, D2, All Non-contact Door Switch inputs connected to the
Switch input D3, D4 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 T31, T32, To set the safety outputs in the ON state, the ON state
input T33 signal must be input to T33.
Otherwise the safety outputs cannot be in the ON state.
To set the safety outputs in the ON state, the signal in-
put 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.
Logical AND T41, T42, A logical AND connection means that one unit (Unit A)
connection input T51, T52 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 in-
put to Unit B.
Thereby the logic of the safety output "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.
Cross fault Y1 Selects the mode for the failure detecting (cross fault
detection input detecting) function for the safety inputs of G9SX corre-
sponding to the connection of the cross fault detection
input.
Instantaneous S14, S24 Turns ON/OFF according to the state of the safety in-
safety output puts, feedback/reset inputs, and logical AND connec-
tion inputs.
During OFF-delay state, the Instantaneous safety out-
puts are not able to turn ON.
OFF-delayed S44, S54 OFF-delayed safety outputs.
safety output
The OFF-delay time is set by the OFF-delay preset
switch.
When the delay time is set to zero, these outputs can
be used as non-delay outputs.
Logical AND L1 Outputs a signal of the same logic and at the same time
connection output as the instantaneous safety outputs.
Auxiliary monitor X1 Outputs a signal of the same logic and at the same time
output as the instantaneous safety outputs.
Auxiliary error X2 Outputs when the error indicator is lit or flashing.
