INSTRUCTION
4.8.3 Performing an automatic test
This function is available only with ‘Ejection Mode’ set to ‘F’.
It is possible to perform some tests in automatic mode (see MTI parameter); during the automatic
test, the Metal Detector simulates the transit of the test sample by generating the same signal
produced at the last manual test, verifying the correct activation of the alarm and the ejector. If the
manual test has been triple (Test Fe, Test NFe, Test SS), it is performed by simulating the lowest
signal among those related to the passage of the three test samples.
The first test after switching on the Metal Detector, a change in the Detection, Ejection and Current
Product Speed parameters or a Fault condition, must be carried out manually by the operator using
standard procedure. Any subsequent automatic tests, defined according to the programming of MTI
parameter, will be performed automatically by the Metal Detector.
Automatic tests are performed only if the signal provided by the samples during the previous manual
test is at least 3dB. Otherwise, at the next scheduled test request, the Metal Detector will require a
new manual test.
Check that the Metal Detector is calibrated to detect test samples with a minimum amplitude of 3dB.
The automatic test is performed only during belt movement (if present); otherwise, the automatic test is automatically
delayed.
