Description of operation
Connect the power source to the A1 and A2
terminals.
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.
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.
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.
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.
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.
Outputs a signal of the same logic and at the same
time as the instantaneous safety outputs.
Outputs a signal of the same logic and at the same
time as the instantaneous safety outputs.
Outputs when the error indicator is lit or flashing.
