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
