Oscilloscope function
This application enables checking the barrier signals in real time.
Timescale: it selects the timescale on the axis of ordinates.
Traces to display: it enables the displaying of traces.
Traces to display
White line: it indicates the signal received from the barrier
Red line: it indicates the set threshold alarm
Green/yellow line: it indicates the valid signal threshold; the signals inside the two lines do not
start the integration circuit of the signal (compensation)
Signal received
The quality of the signal depends on many factors, mainly
environmental. A stable installation passes through the research
for minimum disturbance on the barrier. For a correct installation,
it is important to keep away all those objects that might oscilla-
te in the presence of wind, for example, hedges, branches,
metal nets, etc. It is some times sufficient to slightly adjust both
pairs from the opposite side compared to the possible
disturbance to make the barrier stable, being careful that this
does not jeopardise the signal level.
EXAMPLES OF RECEIVED SIGNALS
Good signal
Slightly disturbed signal
Disturbed signal - it is necessary to check if, by
adjusting, the disturbance reduces.
Very disturbed signal - it is necessary to check there
are no oscillating objects within the zone of interest
of the barrier; it may be necessary to move the
barriers away from the disturbance.
Very disturbed signal with accentuated risk of
unwanted alarms.
Alarm signal.
