Ordering Information

Connection Cable (sold separately)

Function

Interference Protection

You can change transmitted light frequency to prevent interference from several units.
To change transmitted light frequency, input 0V for over 1 second to 4th terminal, (black) MODE, in installation mode.
Frequency type is displayed by frequency indicator.

| | Transmitted light frequency| Frequency indicator
---|---
Green1| Green2| Green3
Frequency A| | |
Frequency B| | |
Frequency C| | |
Frequency D| | |
Frequency E| | |

Installation Mod

This function is for stable installation.
Inputting 0V to 4th terminal of emitter which is (black) MODE, supply power to the product to enter to the installation mode.

Self-Diagnosis Output

This function outputs self-diagnosis signal, when front screen is contaminated with dust, optical axis is misaligned due to vibration, emitter is damaged due to the long-term usage, or light t is not received due to obstacle such as leaves and trash on the product.
It operates in the operation mode, and you can check the status through an external device which is connected to 4th terminal of emitter, (black) MODE.

Self-Diagnosis

If there is checked malfunction during normal operation by regular self- diagnosis, control output

● Diagnosis item

① Break of light emitting element ② Break of emitter
③ Break of adjacent emitting element more than 2. ④ Break of receiver
⑤ Emitter failure ⑥ Receiver failure
⑦ Malfunction of synchronous cable

Installations

For the first installation, enter installation mode.
①Entry method for installation mode: Supply power with inputting 0V to 4th terminal (Black) MODE.
②After entering installation mode, install the unit at the position where green LED of receiver operation indicator turns ON.
③After installation, re-supply power to the unit.

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

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.
