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
Æ
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.
g) Rotate function switch
SW1 to Position 7
, and it is possible to read and/or modify
the
Maximum Range (LR-FTD Long Range Fuzzy Target Discrimination).
The
maximum range determines the sensitive area of the protection field and even if all
the conditions are met to generate an alarm, but the target is at a greater distance
than set, no alarm will be generated. The value is expressed in metres.
Using
Murena Plus Curtain as "Rain"
, the
maximum distance must be less or
equal to the height of sensor.
Led

will 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 01 and 24 (
default of 8m)
Murena Plus 24 default is 16m
.
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.
