POLITEC s.r.l
Perform an initial visual alignment between the two columns (TX and
RX).
Horizontal orientation:
Loosen the screws and turn the column.
Vertical orientation:
Loosen the screws of the handling system of the parable, and
rotate.
Verify that on the board RX the leds alarm and Channel are on. Otherwise proceed
with the electronic alignment, however, be made to obtain a precise alignment.
Electronic alignment.
1. Turn ON the dip of the "Selector Function" numbers 1,2 and 3, leaving all
others to OFF.
Align horizontally and vertically then the parable of the receiver for maximum
signal seen on "Led test alignment”.
If the signal is too strong or too weak to act on the knob of the "gain" so that
only the first four LEDs light up red.
Rerun the orientation of the parabola RX. Once the maximum orientate the
parable TX.
2. Goodness signal: Turn OFF the switching of the "selector functions" 1 and 2
and ON the numbers 3,5 and 10 for the Voltmeter display the gain value. The
optimal values are between 4.5 and 6.5 volts.
3. AGC: position ON the switches numbers 1 and 2 of the "Selector Function",
leaving all others to OFF. Check after about a minute that the 4 LEDs are lit
red and 2 yellow LEDs for "Led test alignment”,too.
4. Verify that on the board RX the leds alarm and Channel are on. Otherwise
proceed with the electronic alignment.
Walk Test To check the "sensitive area".
1. Turn the knobs "sensitivity" and "Delay" to the minimum and reposition to ¼
of winder.
2. Turn ON the microswitch of the "selector function" Number 4 leaving all
others to OFF. This operation is inserted to signal the buzzer will sound
continuously when there is an alarm (see pp. 11, 12), while with a variable
sound intermittently when in a sensitive area.
