Check the wiring connection.
Check the rated load capacity.
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.
■ Sensing distance change (Long / Short mode)
This function is to change the product detection distance by mode setting for the
installation environment.
When installing more than 3 sets of products closely, set as Short mode to minimize
mutual interference. Set this function via the setting switch of the emitter.
■ Operation mode change (Light ON / Dark ON)
It is available to select with user's preference.
Set this function via the setting switch of the receiver.
- Light ON: The control output is ON when it is light ON
- Dark ON: The control output is ON when it is light OFF
■ Picking indicator (ON / flashing)
Picking indicator is lighting or flashing to make out work sensing operation more
easily. Set this function via the setting switches of the emitter / receiver.
