d) Rotate function switch
SW1 to Position 4
, and it is possible to read and/or modify
the
Alarm threshold.
The alarm threshold is used to determine whether, at the end
of the analysis process, there is a large enough signal to generate an alarm.
To Read
the alarm threshold value:
Rotate function switch SW2 (units) until the red led (DL9) comes on. Note the
position of SW2.
Rotate function switch SW3 (tens) until the red led (DL8) comes on. Note the
position of SW3.
The values read on these switches vary between 01 and 99 (
default of 50).
To Modify
the alarm threshold value:
Rotate switches SW3 (tens) and SW2 (units) to the value required.
Press S1 to confirm the setting and to acquire the new threshold value.
To increase the sensitivity set a lower value. To decrease the sensitivity set a
higher value.
During this phase (
SW1 in Position 4
) it is possible to make a
Walk-Test.
Any
disturbance in the protection field that exceeds the characteristics set up and
validated by the analysis process will activate the buzzer with an intermittent sound,
while led
DL1
DL6
will indicate the level reached by the alarm analysis process.
When this reaches the level that will generate the alarm the buzzer will activate
continuously and all six led will come on.
e) Rotate function switch
SW1 to Position 5
, and it is possible to read and/or modify
the
Upper and Lower Masking threshold.
The masking thresholds are set above
and below the field value, memorised during the acquisition phase.
To Read
the masking threshold values:
Rotate function switch SW2 (units) until the red led (DL9) comes on. Note the
position of SW2.
Rotate function switch SW3 (tens) until the red led (DL8) comes on. Note the
position of SW3.
The values read on these switches vary between 01 and 99 (
default of 20).
To Modify
the masking threshold values:
Rotate switches SW3 (tens) and SW2 (units) to the value required.
Press S1 to confirm the setting and to acquire the new threshold value.
f) Rotate function switch
SW1 to Position 6
, and it is possible to read and/or modify
the
Minimum Range (SR-FTD Short Range Fuzzy Target Discrimination).
The
minimum range creates an insensitive zone close to the detector, even if all the
conditions are met to generate an alarm. The value is expressed in metres.
Led
DL1
DL6
show the distance at which target movement will be detected.
To Read
the minimum range values:
Rotate function switch SW2 (units) until the red led (DL9) comes on. Note the
position of SW2.
Rotate function switch SW3 (tens) until the red led (DL8) comes on. Note the
position of SW3.
The values read on these switches vary between 00 and 12 (
default of 1m).
To Modify
the minimum range values:
Rotate switches SW3 (tens) and SW2 (units) to the value required.
Press S1 to confirm the setting and to acquire the new range value.
If a minimum range value greater than the maximum range value is entered by
mistake the default values will automatically be entered.
