and connect a condenser between 0 V and F.G. terminal to remove noise.
• When connecting a DC relay or other inductive load, remove surge by using diodes
or varistors.
• Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise.

Cautions during Installation
• Be sure to install this product by following the usage environment, location, and
speci󹃐ed ratings. Consider the listed conditions below.
- Installation environment and background (re󹃑ected light)
- Sensing distance and sensing target
- Direction of target’s movement
- Feature data
• If the installation environment has re󹃑ected light from the wall or 󹃑oor, a interval
distance of at least 0.3 m is required.
• When installing multiple sensors closely, it may result in malfunction due to mutual
interference. Install it by referring to the interference protection and the installation
method in the manual.
• Do not use in places where the light-receiving sensor is exposed to direct sunlight or
where the ambient illumination is higher than the speci󹃐cation.
• Do not impact with a hard object or bend the cable excessively. That could decrease
the product’s water resistance.
• Use this product after the test. Check whether the indicator works appropriately for
the positions of the detectable object.

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 󹃑ashes 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 / 󹃒ashing)
Job indicator is lighting or 󹃑ashing to make out work sensing operation more easily.

■For re󹃒ection from the surface of wall and 󹃒at
When installing it as below, the light re󹃑ected from the surface of wall and 󹃑at is not
shaded. Please check whether it operates normally or not with a sensing target before
using. (interval distance: ≥ 0.3 m)

■For protection of interference
It may cause interference when installing more than 2 sets of the sensor. In order to
avoid the interference of the sensor, please install as following 󹃐gures and use the
transmitted light frequency changing function.
• Transmission direction should be opposite between 2 sets.
