2) When using emission halt function
This device incorporates the emission halt function. Using this function, it is possible to
simulate the beam blocked status.
<Reference>
When the emission halt input is kept open, or connected to 0 to +1.5V, the emitter stops emitting light.
In this condition, if this device operates properly, the control output (OSSD 1, OSSD 2) of the
receiver turns OFF.

Notes: 1) The threshold where the control output (OSSD 1, OSSD 2) changes from OFF to ON is applied as
‘100% incident beam intensity’.
2) Since the color of the operation indicator changes according to the ON / OFF state of the control
output (OSSD 1, OSSD 2), the operation indicator is marked as OSSD on the sensor.
3) This is for emission in normal mode. In case of emission in short mode, lights up in orange.
