8) Select ’No’, display now reads:
Signal Delay # # # #sec
Reject Time # # # #sec
9) If inspecting individual product place the sample
pack with metal contaminant in the rear/trailing edge
(must be correct size sample) on conveyor belt and allow
it to pass through the detector without skewing or
slippage.
Press the ’Signal Delay’ soft key and adjust the Signal
Delay Time so that the reject mechanism operates just as
the front/leading edge of the pack reaches the reject
device.
If product is loose place metal sample on belt and allow it
to pass through the detector in a similar manner.
However, adjust the Signal Delay Time so that the reject
mechanism just begins to operate as the metal sample
reaches it.
10) Now position the metal contaminant at the
front/leading edge of the individual pack, pass the pack
along the conveyor and through the detector as before.
Press the ’Reject Time’ soft key and adjust the Reject
Time until the metal contaminated pack is rejected
accurately and consistently.
If the product is loose adjust the Reject Time so that
metal sample is consistently rejected with the minimum of
wasted product.
Press the ’Enter’ key to store the settings in memory.
11) Press ’Enter’ key again, display now reads:
tests using larger metal samples.
If product is loose test reject operation using large and
small samples, also check using two metal samples
spaced at different distances apart on belt.
If for any reason the settings at the timer are thought to
be incorrect repeat the whole of the setting up procedure
from step 1
tm2(G) Gated Yes/No
12) Select No, display now reads
Timer ’A/B/C’ Type tm2 Set/Updated
for five seconds and then returns to the main
menu.
13) For individual products further check the operation of
the reject mechanism by passing contaminated packs
through the detector. Check packs with small metal
samples placed first at the front and then at the rear of
the pack. Repeat the
