Installation Checks
The operating parameters of each detector are pre-selected in the factory, based on its application. In
general, installation does not cause any particular problems when the tips given in the “General Installation
Instructions” have been followed.
The final user is responsible for selecting the appropriate security level/sensitivity for their
application. After this selection has been made, and programming has been adjusted accordingly, it
is also the final user's responsibility to verify calibration using their selected test object.
Additionally, this test should be carried out periodically to insure no changes have been made to the
equipment.
There follows a guide to the sequence of operations to be followed if the
Metal Detector
is to operate at
maximum efficiency. After completing the detector’s mechanical installation and electrical connections, switch
it on and proceed as follows:
a) choice of optimum transmission channel (command CH ).
In the case of multiple installations, follow the
instructions in the section “Installation of coupled metal detectors: synchronisation”.
b) sensitivity adjustment
( command SE )
The sensitivity is pre-set in the factory according to the type of application. Generally, it is only necessary to check proper
detection of a sample supplied with the device or defined by security specifications
Procedure
•
Take the metal mass considered to be the smallest sample to be detected, and make several passages
through the probe. The mass must be passed along the centre line of the archway, changing the
orientation of the sample each time.
•
Carry out the test passing the sample at different heights, so as to find the sensitivity level that ensures
interception of the sample over the whole of the useful archway, as defined in the security specifications.
The correct sensitivity setting is the lowest which ensures detection of the sample at all heights and in all
orientations.
c) Specific security level (commands AU, IS and SE):
The detector is delivered pre-programmed in the AUTOSET configuration. If this configuration does not
permit detection of a reference sample defined by the customer, the sensitivity setting SE can be modified.
If a security level specified by international regulations is required, it can be selected via the IS command
(see Programming section). Thanks to CEIA Metal Detectors’ extreme consistency of performance, this
command allows adjustment of the detector to the specifications of the selected standard without having to
carry out the test procedure physically.
d) check for electrical noise.
Check that activation of electrical devices around the Metal Detector does not
cause interference:
the display should not show more than one asterisk in the green sector

.
e) check for mechanical noise.
Check that the movement of metal masses around the Metal Detector (metal
structures in general, doors, furnishings, trolleys, …) does not cause interference:
the display should not
show more than one asterisk in the green sector
