7) When asked to pass product through aperture
ensure the product is passed in the same orientation
and position each time.
8) When the auto-setup routine has finished it will
display the message ”Product adjustment completed’. The
phase and sensitivity have now been set passing the
product through the aperture should now give 2 to 3
segments on the bar graph display.
NOTE – If the message ’WARNING the phase setting may
be in error appears it may be necessary to trim the phase
and possibly the sensitivity manually (see ’Minimising
Product Effect Signal By Manually Adjusting The Phase
Discriminator’).
9)Test the sensitivity of the detector by passing metal
samples through the aperture of the detector (preferably on
or in the product) and note the results.
SELECTING TIMER A B or C
The timer setting A B or C controls the operation of the
reject device. There are three different timer settings
available however for most applications only one timer
setting will be required.
Possible circumstances which may necessitate different
timer settings are as follows.-
1) Photogated punch/push reject device with a wide
variation in pack length. Adjusting the timing will ensure the
pusher hits the pack in the most effective position.
2) Applications running at different conveyor speed that
necessitate different reject timer setting.
The settings of timers A B and C are set by the Engineer
when the detector is configured.
At this stage the objective is to allocate a previously set
timer to a particular product number as advised by the
Engineer.
1) Enter the supervisor or Engineers Access code
2) Press ’ETC’ key
3) The display asks for a selection A B or C. Select the
appropriate timer setting as advised by engineer.
4) Press ’Prog/Exit’ key and exit programme.
SELECTING INVERSE DETECTION
The action of the reject timer can be reversed such that
product containing no metal contamination is rejected whilst
metal contaminated product is not rejected.
This feature is often used to verify that a product contains a
metallic premium.
This option is only selectable in the engineers mode.
To select inverse detection:
1) Enter the Engineers Access code
2) Press ’ETC’ key until the inverse detection page
is displayed
3) Press the soft key adjacent to YES 4) Press ’Prog/Exit’
key and exit programme.
NOTE:-
a) This option can only be selected if the current timer is
gated (i.e. a tm2G or tm3G).
b) A gated timer can not have its parameters changed if
this option is selected. Inverse detection must be
deselected prior to adjustments.
If the user attempts either a) or b) above, the system
prevents its implementation and displays the required action
on the LCD display, i.e. in the case
of note a) – ”Timer must
be gated for this option’.
