Alarm If Overdue
(Alarm If Overdue – YES/NQ)
If Reject Confirmation hardware is fitted this option can
be selected to operate the system fault relay (See ’Power
Unit Electrical Connections’ in the Installation section)
when a performance check becomes overdue.
Note on module firmware version 2.02 and less the RCU
must be selected in the Engineers mode for this facility to
operate.
Change QA Operator Code (Change Cod” QA # ####)
Allows the setting of the nine QA operator codes.
Select the soft key adjacent to the arrowed line ( ^ – -) to
select the QA operator number (i.e 1 to 9).
Select the soft key adjacent to # # # # and enter the
required code Press ENTER to store the new code in
memory.
PERFORMANCE VALIDATlON PROCEDURE
A performance check may be carried out at any time.
The PVR may have been configured to automatically
prompt the user (normally authorised QA personnel) to
carry out a performance ctieck. This will occur at regular
intervals, determined by the pre-programmed test
interval.
If the test interval has been set the time of the next
performance check can be checked by pressing ETC
twice from the normal running display. the display will
show the ’Current Time” and the Next QA Test time .
NOTE5
1) If the PVR has been configured for timed
performance checks then the test interval time will be
restarted when-ever a performance check is carried
out
2) If the operator wishes to check the operation of the
reject mechanism to its highest level, to ensure correct
operation at the worst case extremes it will be necessary
to follow instruction
13) on Page 22 when passing through the sample or
contaminated pack Also refer to ’Sample Size’ on Page
21 to ensure that the correct size sample is used.
Carrying out a performance check;
The test sample(s) should be passed though the metal
detector with the product.
If inspecting individual products prepare a sample pack
(one for each> test sample) containing the test sample.
Position the test sample at the rear/trailing edge of the
product and in a position which places it as close as
possible to the centre at the aperture metal detector
aperture when the product is passed through the
detector.
1) Enter the QA access code (QA inspector or QA
Operator ).
2) It accessed by QA inspector code press ’TEST’, the
display reads
FERROUS NONE FERRQUS
EXIT STAINLESS STEEL
3) Select the material to be tested, the display reads -
Pass . #.#mm i Fe. / N-Fe. / S/S sample
PASSED
FAILED
4) The display prompts the operator to pass the’ selected
test sample through the metal detector.
If inspecting individual product place the sample pack
prepared earlier on the conveyor belt and allow it to pass
through the detector.
if the product is loose place the test sample on the
conveyor belt (or into the product flow) and allow it to
pass through the detector.
Ensure that the test sample is detected and (if applicable)
that the sample pack / test sample i-; successfully
rejected.
If note 2) is being followed it may be necessary at this
point to pass the contaminated product or test sample
through again.
Enter the result of the test by pressing the ’PASSED’ or
’FAILED’ soft key, the display reads as shown in 2).
If a LPU is installed, the result will be printed for
confirmation of the test.
If there are more test samples to be checked continue
from step 3),
If the performance check has been completed press the
’EXIT’ soft key or the ’PRQG/EXIT’ key.
