I. Introduction to MDSC-1000B
Thank you for purchasing MDSC-1000B series metal double-sheet detectors
independently developed and manufactured by Atonm (Guangzhou) Intelligent
Technology Co., Ltd.. The product is mainly used in automatic feeding system of
various industries to detect the thickness difference of various kinds of metals (such
as aluminum sheets, iron sheets, copper sheets, stainless steel sheets, etc.) and can
effectively prevent double-sheet or multiple sheets together being sent to the next
process, so as to avoid the damage to the equipment. This product is composed of
two parts: detecting host and sensors.
This manual is mainly to describe the specifications, properties, and using
methods, etc. of MDSC-10000B series metal double-sheet detectors. Before using the
product, please carefully read this manual, so as to clearly know the properties of the
product and safely use it.

Notes: All the pressing keys can only be operated after long pressing the "Confirm"
key to enter the setting mode. Otherwise, it is void!
(3) LED indication
LED is used to indicate the real-time testing state of the sensors. When it is zero
sheet, the blue LED is on; when it is single sheet, both the blue and green LED lamps
are on; when it is double-sheet, all the blue, green and red LED lamps get
illuminated.
Under study mode, the corresponding LED indicating lamps flickering means
that they are undergoing study at their corresponding states.
V. Installation and wiring instructions
(1) Host installation
Open a rectangular hole of 121mm * 105mm in the equipment panel at the
installation position and put the testing host into it. Then insert the fixing clumps at
the hole opening position of the top and bottom sides of the host and tighten the
screws.
(2) Installation of sensors
It is suggested that the sensors for the metal double-sheet detector be installed
on the metal or plastic supports as shown in the diagram: the transmitting port T is at
the bottom and the receiving port R is at the top; the working sides (with black
circular plate) are installed at opposition. The distance between the working sides
allowed is 30~50mm and 40mm is recommended. When the testing sheet is relatively
thick (The magnetic material whose thickness is over 2mm.) or its area is relatively
small (Its diameter is less than 10cm), the distance can be adjusted to 30mm; when
the testing sheet is thin (such as the non-magnetic material is less than 0.5mm), the
distance can be adjusted to 50mm.
When material feeding is being tested, the testing metal sheets should pass

through the valid induction area (at least it should approximately align with the
internal edge of the sensor, or more deeper into the area). The installation position is
recommended as the following diagram.
Note: Net space is required for the sensors' facing area and can't be sheltered by
other metals.

VI. Host debugging procedures
Preparations: Install the testing host and sensors well as request and connect the
electric wires. Switch on the power, and the LCD displays normally, which means
that the host is under the working mode. If all the parameters have been set earlier
and the metal sheets conveyed remain unchanged, then the host can directly work.
Otherwise, the setting should be done as the following procedures.
(i)Auto adjustment

Place a metal sheet and Shortly press the Single-sheet Setting Key. Until the Double-sheet LED
flickers, move away the metal sheet.
不放片料，短按零张设定键，短按确定键保存，长按返回键退出：
Do not place the metal sheet, and press the Zero-sheet Setting Key. Shortly press the Confirm Key to
save and long Press the Return Key to exit.
①Long press the “Confirm”key for 3s until the LCD gets illuminated, and
then the setting mode is entered. Shortly press the “Auto Adjustment”key. At the
time the “Single-sheet”indicating lamp flickers and the automatic adjustment mode
is entered.
②Let the feeding control system convey one metal sheet to the middle of the
sensors and stop. At the time the largest area of the metal sheet lies in the center of
the sensors (If it cannot be realized by the feeding control system, the operator can
also manually take one metal sheet into the center of the sensors. The position where
the metal sheet being placed should be consistent with that made by the feeding
control system as much as possible.). Shortly press the “Single-sheet Setting”key
and only until the “Double-sheet”red indicating lamp flickers can the single metal
sheet be moved away. Then the single-sheet adjustment has been completed.
③Let the feeding control system convey two metal sheets together to the
center of the sensors (If it cannot be realized by the feeding control system, the
operator can also manually take one metal sheet into the center of the sensors. The
position where the metal sheet being placed should be consistent with that made by
the feeding control system as much as possible.). Shortly press the “Double-sheet
Setting”key and until the three LED indicating lamps get illuminated move away the
double-sheet. Then the double-sheet adjustment has been completed.
④Move away the metal sheets and let the middle of the sensors not be sheltered.
Shortly press the “Zero-sheet Setting” key, and at the time the “Zero-sheet”
indicating lamp flickers. Shortly press the “Confirm” key to save and then the

zero-sheet setting has been completed. Long press the “Return” key to exit the auto
adjustment mode and enter the working mode.
(ii) dynamic learning (not a must)
If the operation effect is not idea after the auto adjustment has been done, such
as too many wrong reports and missing inspections, etc. (especially when the metal
sheets appear up-and-down moving phenomenon during detecting, it is difficult to
control the dynamic learning.). Therefore, suggest increasing dynamic learning after
finishing the auto adjustment.

长按返回键 3秒，退出设置模式，进入工作模式：
Long press the “Return”key for 3s to exit the setting mode and enter the
working mode.
⑤Under the setting mode (Long press the “Confirm” key for 3s.), shortly press
the “Single-sheet Setting” key, and at the time the “Single-sheet” green indicating
lamp flickers. The feeding control system normally conveys a metal sheet to pass
though the equipment (under dynamic conditions to pass through the equipment).
Shortly press the “Confirm” key to save, and the single-sheet dynamic learning is
completed.
⑥Shortly press the “Double-sheet Setting” key and at the time the
“Double-sheet” red indicating lamp flickers. The feeding control system normally
convey two metal sheets that they are stuck together to pass through the equipment
(under dynamic conditions to pass through the equipment). Shortly press the
“Confirm” key to save and the double-sheet dynamic learning is completed.
⑦Completing the setting: Long press the “Return” key for 3s, and the backlight
of the LCD is power off, which means the setting mode has been exited and the
working mode enters. So far, the setting has been completed and the detecting work
can be done. Each time when the metal sheet has changed its specification or the
position of the feeding material appears big change, it is required to adjust the
equipment once more.

(iii) Manual setting (not a must)
If you feel single-sheet or double-sheet detecting is not sensitive enough or too
sensitive, then you can long press the “Confirm”key for 3s to enter the setting mode.
After that shortly press the “Confirm”key, then the numbers beside the
“Single-sheet”on the LCD will flicker. At this time, you can press “Up”or “Down”
key to adjust the sensitivity value of the single-sheet. The bigger the number, the
higher sensitivity. Then press the “Confirm”key to save the sensitivity setting of the
single-sheet and turn to the sensitivity setting for the double-sheet. At the moment,
the numbers beside the “Double-sheet”on the LCD flickers. The sensitivity
adjustment of the double-sheet can be done as that of the single-sheet. After finishing
adjustment, press the “Confirm”key to save. And during the sensitivity adjustment
for the single-sheet or double-sheet, you can press the “Return”key to exit
adjustment and resume the previous sensitivity setting.
Notes: During sensitivity adjustment for the single-sheet or double-sheet,
that is, when the numbers on the LCD are flickering, the seven steps ①~⑦
cannot be done. Non-professionals are not suggested to operate the manual
sensitivity setting.
