- When using switching mode power supply to supply the power, ground F.G. terminal 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.
- This unit may be used in the following environments.
– Indoors (in the environment condition rated in ‘Specifications’)
– Altitude max. 2,000 m
– Pollution degree 2
– Installation category II
Cautions during Installation
- Be sure to install this product by following the usage environment, location, and specified ratings. Consider the listed conditions below.
– Installation environment and background (reflected light)
– Sensing distance and sensing target
– Direction of target’s movement
– Feature data - If the installation environment has reflected light from the wall or floor, a interval distance of at least 0.5 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 specification.
- 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
In case of using 2 sensors in parallel in order to extend sensing width, it may cause sensing error because as light interference. This function is operating a sensor as MASTER and another sensor as SLAVE to avoid these sensing errors by the light interference. Connect ‘(TEST)M/S’ of SLAVE emitter to ‘SYNC’ of MASTER.
• Time chart for MASTER/SLAVE transmission pulse
• MASTER / SLAVE connections (NPN open collector output)
• MASTER / SLAVE connections (PNP open collector output)
Emitter OFF (external diagnosis)
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. If the emitting stops, sensor is in light OFF status and control output of receiver turns OFF.
• Connections for TEST input
• Control output pulse by TEST input
■ Optical axis misalignment alarm (low light intensity alarm)
This function outputs optical axis misalignment alarm, when front screen is contaminated with dust, optical axis is misaligned due to vibration, emitter is damaged due to the longterm usage, or light t is not received due to obstacle such as leaves and trash on the product. The control output is changed according to the degree of optical axis misalignment, and the red and green operation indicators of the receiver flash alternately in 0.5 sec, and the yellow operation indicator turns on.
■ Self-Diagnosis
If there is checked malfunction during normal operation by regular self-diagnosis, control output turns OFF and operation indicator displays the state.
For more information, see the “Operation Indicator”
- Break of emitter circuit
- Malfunction of MASTER / SLAVE line (operation in MASTER)
- Break of receiver
- Control output over current
- Noise of synchronous line
Installations
■ For direction of installation
Emitter and receiver should be installed in same up/down direction.
For reflection from the surface of wall and flat
When installing it as below, the light reflected from the surface of wall and flat is not shaded. Please check whether it operates normally or not with a sensing target before
using. (interval distance: ≥ 0.5 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 figures and use the transmitted light frequency changing function.
• Transmission direction should be opposite between 2 sets.
• It should be installed out of the interference distance.
: It may be a little different based on installation environment.
: Avoid using the unit in the place where the sensor is exposed directly to the fluorescent light with high speed start or high frequency.
