Introduction
This manual describes how the AD-4971
Metal Detector
works and how to optimize its performance. Read this
manual thoroughly before using the Metal Detector and keep it at hand for future reference.
The AD-4971
Metal Detector
detects metal contained within the product by measuring a change in the magnetic
fields surrounding the product. The methods it uses to detect metal are non-contact and non-destructive.
1.1.
Features
Display Unit
The AD-4971 is equipped with a 7-inch touch sensitive screen for easy operation.
The touch sensitive screen provides an interface which is simple to understand and operate.
Waterproof and Dustproof
The AD-4971 is equipped with a waterproof and dustproof frame in compliance with IP65.
Conveyor Belt
In comparison with timing belt drives, the gear-driven conveyor belt mechanism allows for easy maintenance
(removal, attachment, and tracking and tension adjustments).
Functions
The AD-4971 can divide products into ten groups and register a maximum of 100 products for each group (a total of
1000 products).
Product images can be uploaded from a connected USB flash drive.
The user registration function is provided to assign a management level appropriate for each user. This ensures safe
operation of the system.
Serial communication or TCP/IP communication allows communications with Modbus-enabled devices without a
communication program.
Interface
The AD-4971 is equipped with a rejecter control output, emergency input, alarm output and RS-232C interface.

1 Introduction - 1.2 Safety Precautions

1.2.
Safety Precautions
Read the precautions before using the AD-4971 for safe use.
CAUTION
Rotating Object Hazard
Keep hands and fingers away from the rotating parts while the AD-4971 is running.
When the product falls over, spills or starts accumulating in a pile up on the conveyor, stop the AD-4971 immediately,
turn off the power and take necessary actions.

Electrical Shock Hazard
Be sure to turn the power off before removing the display cover or I/O box cover for inspection.
Keep the power turned off during the inspection.
Only turn on the power after the installation has been completely finished.
If there is a short circuit, kill the breaker without touching AD-4971.

Precautions When Installing
Install the AD-4971 on a solid surface away from sources of vibration.
Install the AD-4971 in an area where it is not exposed to direct sunlight.
Install the AD-4971 in an area where it is not subject to drafts from windows, electric fans or air conditioners.
Be sure to install the AD-4971 on a level surface.

Grounding
Be sure to ground the AD-4971 to avoid electrical shock, fire or malfunction.

Precautions for Use
Do not apply shock or excessive external force to the conveyor belt.
Do not apply a load exceeding the weighing capacity of the conveyor belt.
Do not modify or disassemble the AD-4971. Do not change the parts and/or units.
Feed the product into the AD-4971 at constant intervals.

Cooling the Unit
To avoid overheating the AD-4971, leave a space between it and its peripherals.
If the temperature surrounding the AD-4971 exceeds the specified operating temperature range, cool the area down
(floor, wall, etc.) using a fan and/or air conditioner.
