Functions
■ Interference protection (transmitted light frequency change)
When you install more than two products, there is a risk of mutual interference.
Change the frequency to prevent this interference. Set one sensor as frequency A and
the other as frequency B via the setting switch.
■ Emitter OFF
When 0 V is applied to the TEST input of the emitter, the light emission is forcibly
stopped and the external system can check whether the sensor is operating normally.
When the emission is stopped, the light is blocked. In the case of Light ON mode, the
control output turns OFF. In the case of Dark ON mode, the control output turns ON.
The red LED of the emitter flashes until the TEST input is released.

■ Operation mode change (Light ON / Dark ON)
It is available to select with user's preference.
- Light ON: The control output is ON when it is light ON
- Dark ON: The control output is ON when it is light OFF
■ Job indicator (ON / flashing)
Job indicator is lighting or flashing to make out work sensing operation more easily.
