Press again the button
S1
, the sound will has a lower intermittent frequency.
Now change again the horizontal orientation.
In the event that during the orientation operation, the frequency of the intermittent sound
decreases, means that the received signal is decreased, therefore move the head in the
opposite direction.
The operation of horizontal alignment will be finish when the maximum signal will be
found.
f. Slacken the bracket
‟s screws to orientate the
transmitter
horizontally, repeat the
operations explained in the “e” point.
N.B.
The transmitter
head doesn‟t have the
S1
button, therefore to activate the “fast
regulation system”, cover temporarily the radiofrequency emission ( for example, pass an
hand in front of the
transmitter‟s antenna) so that the alignment operation will be easy to
execute alone.
g. When the best alignment will be found (the maximum signal available) lock the
movement on the receiver and on the transmitter.
h. Unlock the vertical movement of the receiver head (Rx) and move it up. Press the button
S1
or cover temporally the radiofrequency emission, and wait the stabilization of the
intermittent sound.
Move down slowly the head and find the maximum signal (see point “e”).
i. Unlock the vertical movement of the transmitter head (Tx) and carry out the same
operations than the receiver. Finally lock the movement of the transmitter and the
receiver.
j. Turn the functions switch
SW1 in the position 2
, make sure that during this operation
nothing is within the microwave beam
, for example the operators don‟t walk between the
transmitter and the receiver.
Remember that this operation is very important because now the barrier acquire the
value of the modulation channel and the value of the microwave signal.
An alteration of the microwave beam in this moment will make incorrect the installation
therefore it will be NOT safe.
The acquisition operation starts some seconds after that the button S1 is pressed. When
the acquisition operation will finish the 3 leds will turn on together and the buzzer will
make some sounds (Beep) which indicate the quality of the alignment:
1 beep
= Excellent Quality
2 beeps
= Good Quality
3 beeps
= Poor Quality
4 beeps
= Insufficient Quality
5 or more beeps = Very bad Quality
In the event that the alignment quality is poor or less, verify that nothing, fix or moving, is within
the microwave beam and than repeat the alignment operations.
