a)
Before it is put into use, the instrument should be put in a horizontal place where there is
no vibration. It is expected to adjust the four boy-bolts until they support the instrument
stably and the four direction wheels disconnected with the ground. When the instrument
is in a horizontal position, fix the fastening bolts until they do not vibrate. Otherwise, the
conveyer belt will sway.
b)
The instrument is not allowed to install on an operating platform made of iron or beside
an iron frame.
c)
The instrument is not allowed to install beside a machine that will cause magnetic field
as it will cause electricity and interference of magnetic field, which may result in wrong
operation of the instrument. These machines include: motor-driven clutch motors, sewing
machines, tailoring machines, balers, air-conditioners, high-tension bus-bar ceiling fans,
and machines that have rotating mechanism.
d)
The instrument should be installed in a place far away from huge movable iron objects,
such as trains, motor vehicles, etc.
e)
The instrument should be far away from materials made of steel and iron, such as iron
doors, iron windows. The direction of the major parts of the instrument could be adjusted
so as to change the location of the instrument to avoid wrong operation.
f)
The instrument will cause a magnetic field. Operators should pay attention to the credit
cards, cards of drawing, telephone cards with them, and telephones around, etc that
might be affected by the magnetic field of the instrument.
g)
The instrument should be installed in a temperature surrounding from 0
°
C to 40
°
C , a
place that will never be lower that the frozen point.
h)
There should not be any flowing dusts, ferrous powder, and abrasive grits in the place
that locates the instrument. The place should not be moist and dew forming as well.
6.
The Adjustment and Installation of the Sensitiveness:
a)
The level of adjustment should be adjusted to “6-8” for sensitiveness. The level of
adjustment should be adjusted to “9-10” in order to detect trivial needle tips and iron
fragments. At this stage, higher demand is raised against the interference of the
surrounding metals and for the cleanness of the belt by the instrument
b)
Detection could not be made among the products until one has been sure that the packing
and the subsidiary materials such as paper bags, paperboards, nylon packing bags,
buttons, and zippers are inactive to the instrument.
c)
If the conveyer belt pause only because of the subsidiary packing materials, one should
adjust the button of sensitiveness from level “8-10” to level “5-7” so as to ensure that the
belt will no longer pause only due to the subsidiary materials.
Note
: If the button of sensitiveness is adjusted to level “4” or lower, it will be difficult to
detect trivial metal materials and needle tips.
d)
If the conveyer belt remains pause even after the adjustment of the button of
sensitiveness, one should: complete the detection of the packing and the subsidiary
materials first before one finalizes the selection of the packing materials so as to make
sure the packing and the subsidiary materials will pass the instrument normally.
e)
The power source should be switched off after the completion of the detection. The
power line should be extracted from the plug receptacle if the instrument will not be used
