Adjustments
1) Orientate at sight the device in the
direction of the transmitter and
connect a voltmeter betwen the ne-
gative (-) and
TP
terminal (Test
Point) on board
2) Orientate the device in horizontal
way, looking for the position giving
the max reading; in case it is over
7,3 Volt tthe signal level must be
reduced by use of
LEVEL trimmer
,
in such a way as to bring the signal
to the best point of working, that’s
to say 7,3 Volt
• It is possible to have a high value
also with receiver not aligned to
transmitter; in this case it could be
a reflection of the beam
transmitted, which must most be
taken into consideration.
• In case the signal does not reach 6,8 V having LEVEL trimmer at max, move the device in
vertical way within a limit of 10-20 cm.
• Shouldn’t it be possible to reach the min. value, it will be necessary to decrease the distance
between receiver and transmitter or look for a better alignement position
3) Check the quality of the signal received, keeping in mind that in absence of seeming
movements inside the protected area:
• Green Led on fix: there is no signal noise
• Green Led quick or slow flashing: the signal noise is low but
is anyway detected by the beam
• Green Led slow flashing (off for about 1 second) , the signal noise
is more important and it is near to the intervention threshold of the beam
In order to have a more precise indication on the quantity of noise and to have the possibility
of making adjustments according to the environmental context, we suggest to use the software
HPSOFT
4) after all tests, LEDs can be deactivated in order to reduce the consumption of the receiver
Note:
Thanks to the
digital trimmer
, the barrier has the possibility of self-calibrating the
signal
level
(LEVEL) and to compensate the environmental variations, guaranteeing the stability of
the signal. Fog, snow, gradual variations of the reflecting surface will be automatically
compensated by the barrier, both in positive and in negative, within certain values. Should
the requested variation be above that tolerated by the system, the disqualification signal
(FF) will be had.
