Garrett MT 5500 User Manual page 16

Check all connectors; check for very large object near Panel A.
4.1.2.6 Error 6: No Line Sync
If unit is in Slave Mode, check synchronization cable; otherwise, verify that the unit is set to Master.
If an error occurs, follow the procedures noted above and press OPERATE to retest. You will be
prompted SELF-TEST OK when all functions are correct. If problems continue to occur, consult with
your supervisor or factory representative.
The self-diagnostic/reporting cycle described above will be carried out automatically by the unit any
time the OPERATE touchpad is pressed.
4.1.3 FATAL ERRORS
The system continuously performs several of the tests described above. Errors 1,4 and 5 severely
limit or prohibit acceptable performance of the MT 5500 and are considered Fatal Errors.
If a fatal error is encountered because of component failure, broken wire, etc., the audible alarm will
sound and the LED display will begin to flash. To remedy the situation, press the OPERATE touch-
pad, which will initiate the self-diagnostic routine. Note the error(s) that will appear on the LED and
follow instructions stated above. If a solution is not obvious, it will be necessary to follow the repair
procedure described in Section 9.2.
4.1.4 NON-FATAL ERRORS
Errors 2, 3, and 6 may also occur. These failures do not limit the system's detection capabilities and
the unit will continue to operate. Although the equipment is usable, it is important to identify and cor-
rect all problems as soon as possible in order to maintain full performance capabilities.
Another error indication is that of a warbling audio when a person is in the archway (or, for an extend-
ed time if the IR Analysis is switched off). This sound indicates that a large metallic object, such as
a wheelchair, stroller, or very large hand-carried object, has "overloaded" the equipment to a degree
that it cannot function accurately. If this sound is heard, the operator should see that the problem
object is moved away, and the person being inspected should be required to pass through the arch-
way again after the green READY light appears.
