PYTHAGORAS 3
11 MICROWAVE ALIGNMENT AND CONFIGURATION
11.1 Alignment and Configuration
The PYTHAGORAS3 barriers have an electronic alignment system, a system for parameter
adjustment and a test system which greatly simplify both the installation and routine
maintenance without the need for special tools.
11.1.1
Operations at the TRANSMITTER
Open the column following the procedure described on the paragraph 2.1. Removing the top
cover 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
Transmitter interface circuit.
2. Set the beam number. For each TX head there are two methods for setting the barrier
number.
a) Local assignment, not remotely modifiable;
Assigning
(writing) the barrier number:
Select a number from 1 to 99 on the proper decimal switches SW1(units) and
SW2 (tens). The value 00 means barrier 100.
If decimal switches SW1 (units) and SW2 (tens) should be positioned on 00, for the
first time it’s necessary to push the button S1 after setting up a barrier number
different from 00.
Reading
the barrier number:
It’s enough to read the setting up of rotary switches SW1 and SW2.
b) Local assignment with the possibility of remote modification.
Writing the barrier number
:
Rotate SW1 to position 0, rotate SW2 to position 0.
Push and then release reset pushbutton S1.
Select the barrier number required (from 1 to 99) using switches SW1 (units) and
SW2 (tens),
Close the
“Tamper” switch. In this phase the Fault (D7) and Tamper (D3) led
change function: they will come on for 3 seconds to confirm the acquisition of the
new number, then after will go off and return to their normal functions.
Read the barrier number
:
Rotate SW1 to position 0, rotate SW2 to position 0.
Push and then release reset pushbutton S1,
Rotate SW1 (units) until green led D3 is on
Rotate SW2 (tens) until green led D7 is on
The number from 01 to 99 represented by the switches SW1 (units) and SW2 (tens)
corresponds to the barrier number assigned to the barrier.
NB: if it is decided NOT to modify the barrier number displayed it is essential to
close the radome without changing the positions of switches SW1 and SW2
.
