MANTA 50 – 80
4. ADJUSTMENT AND TESTING
4.1 Adjustment and Testing
A built in electronic alignment, parameter set and test tool, is provided in the receiver head of the
MANTA barrier. This is a very useful system both for installation and periodical maintenance.
4.1.1 Transmitter Setting-up
•
To remove the radome unscrew the 3 screws until they turn loose, then release them out
gently without remove them completely.
•
Check the d.c. power voltage(13.8V
) at terminals 1 and 2 on terminal block MS2 (Fig. 8).
•
Select, one of the 16 modulation channel available, by the hexadecimal switch (within 0
and F). To increase the resistance to tampering actions, it is a good rule to preset different
channels for the different barriers installed in the same site. The use of different channel
doesn’t affect the detection ability of the barrier.
•
Remark
: if one RX receives MW signal from its own transmitter and from another
interfering transmitter (for example due to reflections or any other field reason), it is
necessary to synchronize the two transmitters, selecting one as Master and the other as
Slave. In this case the modulation channel, for the slave transmitter, is the same selected
on the Master regardless its own selection.
•
It is possible to
address
each Transmitter Head thanks to the selectors SW2 and SW3.
•
How to write the address in the TX head: it is enough to select a number between
01
and
99
(00 means barrier 100), by the two rotary switches
SW3
(units column) and
SW2
(tens
column).
4.1.2 Receiver Setting-up
•
To remove the radome unscrew the 3 screws until they turn loose, then release them out
gently without remove them completely.
•
Check the d.c. power voltage(13.8V
) at terminals 1 and 2 on terminal block MS2 (Fig. 9).
a. Be sure that the tamper switch
S1
is activated (Open circuit)
b. Select by the “function switch”
SW1 position 1
. The electronic alignment phase is activated.
c. Push
S3
button. This action adjust the signal level and freeze, after some seconds, the
Automatic Gain Control. In that condition the buzzer BZ1 will produce a pulsed sound, this
means that the field signal has reached the proper working level.
d. Unscrew lightly the bracket screws and move the horizontal alignment of the receiver, looking
for the maximum received signal.
e. If, during the alignment, the pulse frequency of the sound, produced by the on board buzzer,
increases, means that the received signal level is increased compared with the previous. In
this case push again the button S3 and when the pulse frequency of the sound becomes
again lower (proper working level), move horizontally the head in the same direction.
If during the movement for the alignment, the pulse frequency of the sound produced by the
buzzer, decreases, means that the received signal level is decreased compared with the
previous, so it is necessary to move back in the other horizontal direction and look for a better
received signal. If there is not a new maximum level, means that the present horizontal
alignment is the best.
