1. The instrument
does not work
a) The current is not input
Check up on the plug receptacle to see
whether the hot line and neutral line are
in good condition or not, whether the
power is on or not, and whether the
voltage is normal or not.
b) Broken safety wire(s)
Change the safety wire 10A in the
power panel.
c) The problem(s) about the
switch of the current
Change the identical type of switches.
2. The conveyer belt
does not work
a) The conveyer belt is too
loose
Fasten the belt appropriately and stop
fastening when it works.
b) The triangle conveyer belt
loosens
Adjust it appropriately or change a new
one.
c) The inscribed wire of the
current panel loosens
Check up and connect the wire.
d) The electric relay is
injured.
Check up on the wiring of the plug
receptacle or change a new one.
e) The button is injured.
Check up on the button of “START”,
and change a new one if required.
3. The conveyer belt
stops
or
reverse
upon pressing the
button of “START”
a) Iron fragments and other
contaminants adhere to the
conveyer
belt
and
the
detection devices
a)
Clean both sides of the
conveyer
belts
and
the
detection devices;
b)
Change the belt if necessary.
b) There exists interference
around the instrument
a)
Eliminate the interference or be far
away
from
the
source
of
interference;
b)
Change the location of operation of
the instrument or the direction of
the instrument.
c) The instrument is not
installed well.
Place the instrument horizontally and
fix the boy-bolts.
d) The level of sensitiveness
is adjusted too high.
Adjust the button to “5-7”. Note: If it is
adjusted lower than “4”, it will decrease
the detection capability towards the
trivial needle tips.
e) The drum bearing bears
magnetism
Change a new bearing that is
demagnetized
and
imported
from
abroad.
4. Trivial iron tips
are undetected
a) They are smaller than the
standard
set
by
the
instrument
Adjust the level of sensitiveness higher
appropriately.
b) The button of the level of
sensitiveness is too low.
Adjust the level of sensitiveness higher
appropriately.
c) There exists strong of
electro-magnetism
interference
Eliminate the interference. Shift the
phase. Connect the earth wire or change
the location
5. The conveyer belt
can
not
work
properly
a) The conveyer belt is
deviated.
If the belt is deviated to the right, fasten
the screws on the side of the instrument
that has no electric motor or loosen the
screws on the left. Minute adjustment
for only half circle. If it still could not
return to the center, adjust the belt for
half more circle in accordance to the
direction of the belt.
The conveyer belt is edge Adjust the conveyer belt.
