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.

To set the safety outputs in the ON state, the ON state
signal must

. 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
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 of Unit B is
(AND). (An AND of inputs “a” and “
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.
Instantaneous
safety output
S14, S24
Turns ON/OFF according to the state of the safety
inputs, Non-contact Door Switch 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.
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.
