3-4 Safety Input Function

It is the function to control outputs 1 / 2 (OSSD 1 / 2) of this device with the safety contact con-
nected to safety input terminals SIN1 and SIN2 or the detection signal of the safety sensor.
When safety inputs 1 / 2 are OFF, control outputs 1 / 2 (OSSD 1 / 2) are forcibly OFF.
1 second or less. In case the time exceed more than one second, This device become lockout
status and control output 1 / 2 (OSSD 1 / 2) becomes OFF status.
