PYTHAGORAS 3
11.1.2
Operations at the Receiver
Open the column following the procedure described on the paragraph 2.1. Removing the top
c
over and opening the radome (front cover) will activate the “Tamper” switch connected to
CONNECTOR
J4
.
1
Connect the DC (13,,8
V
)
power supply cables to terminals 1 and 2 of MS5 of the
interface Receiver circuit.

To optimise the alignment of the barrier and to set the operating parameters without the use
of an instrument, using the integrated electronic system, after a preliminary optical
alignment, proceed as follows:
a. Ensure that the micro switch that monitors the opening of the cover, connected to
CONNECTOR J4, is open.
b. Rotate Function
SW1 to Position
1
. This activates the installation phase of the barrier.
c. Press push button
S1
. This activates the fast signal acquisition system and also activates
the buzzer, with an intermittent sound, which in this phase indicates the level of signal
received.
d. Release lightly the bracket screws and move the horizontal alignment of the receiver,
looking for the maximum received signal.
e. If during alignment there is an increase in the intermittent frequency of the buzzer this
means that there is an increase in the received signal with respect to the previous level. If
the increase in the received signal is significant the buzzer sound may be continuous. Press
push button S1 again and when the buzzer sound becomes intermittent again or with a
lower intermittent frequency (when the signal has recovered) reorientation the head again.
If during the alignment the intermittent frequency drops, instead of increasing, this means
that the received signal has reduced after the movement and the movement should be
reversed in the opposite direction to try and find a new maximum. If the frequency drops no
matter which direction the head is moved this means that the current position gives the
maximum signal..
f. Release lightly the bracket screws on the
transmitter
head and repeat the operation
described in “e”.
NB: during alignment of the transmitter to activate the signal recovery, rather than pushing
the button S1 on the receiver, mask temporary the radio frequency beam (for example by
placing a hand in front of the transmitter antenna) so that a single person can easily align
the PYTHAGORAS3 barrier.
g. Got the best alignment (maximum signal), lock the horizontal movement of the transmitter
and receiver.
h. Release the vertical movement of the receiver head and orientate it upwards. Push button
S1 and wait until the intermittent buzzer has stabilised. Rotate the antenna slowly
downwards looking for the maximum signal as described in “e”.
