Thedetector

(if
fitted)
shouldnow
becompletely
installed.
The
aim
of thissection
is to describe
how
to setupthedetector
for a particular
product,
including
automatic
setting
of detection
parameters
andcalibration
of timersfor
accurate
rejection.
Formoredetailed
explanation
ofthesoftware,
please
consult
thenext
sectioninthe
manual.
lf problems
areencountered
duringsetup,read
thetroubleshooting
section
ofthe
manual.
4.1 Detector
Display
and Keypad
Switch
onthe detector,butnottheconveyor.Thedisplayshould looksimilar
tothat
shown
below.
Figure: Detector displayandkeypad
Thedisplay
has
two
linesof20characters,
and
after
power
onorreset,
thetopline
shows
the current
product
name
andthe bottom lineshows
a "bargraph". The
bargraph
can
beusedtosee
how
good
a product setupis:
thecircles
showthesize
ofsignal

detected,
themorecircles
the
larger
thesignal.Solid
circlesindicate
that metalhas beendetected.Hollow
circles
indicate
product
effect
or metal
contamination
that
isnot large
enoughtotriggerthemetaldetector.
lf manyhollow
circles
are
displayed
eachtimea productpasses
thenthedetector
maybeat risk
from
false
triggering.
When
no
signalisdetectedtwocircleswill
be
displayedonthe
bargraph
toindicatethatthe

4.2 Initial
Test
Everydetector
is shipped
witha testsample
- a small
piece
of metal
to testthe
detector
with.
Thistest

beembedded
intheend
of a 30cm
grey
plastic
stick,
orina credit-card-sized,
plastic-laminated
card.
Before
thedetectoris
shipped,
it is setupto see thissamplewithout
false
triggering
(false
triggering
is
whenthe
detectorindicates
that
ithas
seenmetal
when
none
ispresent,
andis
due
to electrical
noise,
vibration,
large

This
setupis stored
onthe

under
thename
"FACTORY

With

Other
variationswillbe
discussed

parameters
areusedin

This

4.4.2 SynchronisingPhotocell
Thissystem
uses
a photocell to make
surethatthecontaminated

correct

Four
parameters
areusedin

Whenthe detector

situation.When
thedelay

anenabling
alarm
timeris started.
Therejectmechanismwillonly

thisalarm
timeris
active.
As each
product
passes
alongthebeltitbreaks
thesynchronisingphotocell

generates
a photocellpulse. A photocell delay
timer
isthen
started.
lfthis
expires
and
the
product
wasuncontaminatedthen
the
alarm
timerwill
not
beactive
so nothing
happens.Howeverif the product
was contaminated
then,
whenthe
photocell
delaytimerexpires,thealarm
timer
should
beactive.ln
thiscase
the
reject
relayis
activated.
ln orderto set
this
timer
up,set
thedelaytimeto 0.01s
andthealarm
time
to
something
large,e.g.
10.0s.
Set

i.e.
if the reject

andvice

Once

the

Attacha metal

and
pass
the

through
themetal
detector.
The

should
be
rejected.lncrease
thedelaytime
by
0.1s
and
pass
the

again.
Keep
doing
thisuntilthe

isnot
rejected.
Decrease
thedelay

0.15s
to allowa safety
margin.
(lf the system
has a variable
speedconveyor
decreasethe

Tosetthe
alarm
timea similar
procedure
isperformed. This
timethemetalsample
should
beplaced
onthe

ofthepack, andthealarm timedecreased
untilthe
