Workers Approach Warning System Yoshikawa Kogyo Co., Ltd. User's Manual 1. About this system ～ Be sure to read this section before use.～ ・ This system can provide only warnings to drivers and workers, and the braking operations such as braking of vehicles must be performed by the driver. ・ It is impossible for this system only to prevent all accident. You must confirm the safety by sight as before. ・ Consult with us if you have a heart pacemaker or a medical device such as a life support device installed. ・ Radio wave interference in the surrounding area may cause the range of radio waves to change. We recommend measuring the radio wave environment in advance in the vicinity of electronic devices, power supply panels, cranes, and other heavy equipment. ・ The detection range varies depending on the installation environment and surrounding conditions. ・ After installation, confirm that the unit is operating correctly by following the operation check procedure. ・ Confirm proper operation according to the daily inspection procedure in the User's Manual. ・ Use in extremely high or low temperatures may cause malfunction or failure. Use within the operating temperature. ・ Due to legal restrictions, this product is prohibited from being used for applications other than those related to Safety operation of the vehicle. ・ It is illegal to disassemble or modify TAGs. ・ Specifications and appearance are subject to change without notice for improvement.

Glossary NoTermMeaning 1 Detector It has a transmit function by a magnetic field, and an alarm function by receiving a radio signal from a TAG. It has a function to receive the magnetic field from the detector and a function to transmit radio waves. ALERT-TAG has a function to alert you. The magnetic field transmitted by the detector uses the 125kHz band. Stable sensing distance is achieved by using a magnetic field. The radio waves transmitted by the TAG use the 315MHz band. Transmitting radio waves from the TAG to the detector enables the detector to alert. They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc.) and moisture. As defined by International Standard EN 60529. IP6 * [0 to 6] Dust-proof 6: Dust does not enter the inside. IP*5 [0 to 8] Waterproof 5: low-pressure jets (6.3 mm) of directed water from any angle Noise that affects the radio waves received by the detector. In places where radio noise is present, the sensing distance that the detector alarms may be shortened. Noise affecting the magnetic field received by the TAG. In places where magnetic field noise is present, the detection distance of the TAG may be shortened. Ex. the power distribution boards, factory equipment and large motors.

What is Worker Approach Warning System? This is a system that alerts people and vehicles to "dangerous situations" , when they are in close proximity with the technology of magnetic fields and electromagnetic waves. 1. A magnetic field (125KHz) is being transmitted from the detector. The direction of the magnetic field is transmitted in all directions by 360°, and the transmission range is an oval shape with the largest longitudinal direction. 2. Radio waves (315MHz) including "Detection signal" and "Magnetic field strength" are transmitted from the TAG in the area where the magnetic field from the detector reaches (max. 8m). 3. The detector sounds an alarm by determining the distance based on the magnetic field strength from the TAG. If you use ALERT-TAG, you can also alert from a TAG. Notes Detection range The detection area is 360 degrees in an oval. The oval shape depends on the orientation of the detector. Depending on the vehicle shape and environment, the detection area may not be an oval. Maximum detection range (e.g., 8m version outside detection range) Long side direction of the detector case: Set distance Short side direction of the detector case: Approx. 80% of the set distance Distance Attenuation in the Environmental conditions The sensing distance may be slightly reduced depending on the environmental conditions (effects of magnetic field noise or radio wave noise, structure of the building including reinforcement, etc.). e.g. 8m may be reduced to 6m. In this case, the setting of the detection distance by dialing decreases proportionally.
