TFV Technical Functionality Verification
(this step requires the FGA-TFV kit be available)
Archway and operator’s condition are as for the FGA step.
The test procedure is detailed in the instructions included in the TFV kit.
FGA Adjustment and TFV Technical Functionality Verification steps are automatically skipped in case the specific model
or the customized configuration does not support these features.

Evaluation and Compensation of Environmental Interferences:
the equipment measures the
noise level due to possible interference sources of an electrical nature only present in the
environment and changes the settings, if necessary, to minimise it. At the end of the process, the
message ‘
ENA END
’ appears, together with the result (example: ‘
COVERAGE 100% NOISE
< 20%
’). The procedure ends with a noise verification. The noise measurement phase can be
prolonged indefinitely to capture a non-repetitive interference.
This step is automatically skipped if a customized security level is selected (see also IS parameter) or the specific
detector model does not support the ENA function.
GENERAL NOISE
ENTER
<general noise measurement>
ENTER
General Environmental Noise Measurement
: the equipment starts measuring the noise level
due to possible interference sources present in the environment, both of a mechanical and an
electrical nature. Pass through the MD in the following configuration:
Eliminate personal metal effects;
Actuate the whole access system;
Activate any electrical devices that may cause interference;
Subject the objects and furniture in the access system to normal and above-normal stress
(hit the furniture, drop a piece of luggage heavily onto the X-ray unit belt, … );
Subject the floor to normal and above-normal stress (walk heavily, change direction, …).
In case of strong gusts of air or wind
EVA function
can be useful to compensate archway vibrations.
If repetitive movements of innocuous big metal objects (f.i. a metal trolley) can occur near the archway
SENT parameter
can be adjusted to avoid false alarms (only if photocell modules are installed).
During the test verify the noise level shown on the display:
0…3
acceptable interference level.
4…8
above normal interference level: the equipment is operational, but a corrective
action on any possible interference source around the MD is recommended.
>8 or alarm indication
unacceptable interference level: the equipment is NOT operational: a corrective
action on any possible interference source around the MD is required.
ELECTR. NOISE
ENTER
<electromagnetic noise measurement>
ENTER
Environmental Electromagnetic Noise Measurement:
the equipment starts measuring the
noise level due to possible interference sources present in the environment, of an electrical
nature only. Activate any electrical devices that may cause interference (motors, monitors, …)
and verify the noise level shown on the display:
0…3
acceptable interference level.
4…8
above normal interference level: the equipment is operational, but a corrective
action on any possible interference source around the MD is recommended.
>8 or alarm indication
unacceptable interference level: the equipment is NOT operational: a corrective
action on any possible interference source around the MD is required.
OTS END
ENTER
End of the OTS procedure
Excessive Environmental Interferences
: in case ENA step results in a coverage less than 100% and/or an excessive
noise level is indicated by EN/GN functions, the installation compatibility should be improved. Apply the following
countermeasures:
- Carry out a corrective action on any possible interference source around the MD (see ‘Preliminary Layout Inspection and
Positioning’ section).
