4 SET-UP AND VERIFICATION
4.1 Calibration and verification on-board
The Murena has an in-built system for setting and reading the operating parameters which
simplifies the installation and periodic maintenance, without the need for any specific test
equipment.
4.1.1 Working on the board
To remove the radome (front cover) release the four screws without removing them.
Removing the radome from the back plate will open the “Tamper” micro-switch.
Connect the power supply (13.8 Vdc) to terminals 1 and 2 of MS2 (fig.3)
To set the operating parameters without using any test equipment proceed as follows:
a) Rotate function switch
SW1 to Position 1.
This activates the installation phase of the
Murena. In this phase it is possible to set the operating mode (Fan, Finger, Rain), the
default active modes are only fan and curtain (finger).
Rotate switches SW3 (tens) and SW2 (units) till
00
value for
Fan
version, or
01
value for
Curtain
(finger) version
Press S1 to confirm the setting.
Led
DL1
DL6
will display the signal level and, in the absence of movement, the
ambient noise of the area.
b) Rotate function switch
SW1 to Position 2,
Rotate switches SW3 (tens) and SW2 (units) till
0
value
ensuring
during this operation that there are no obstacles in front of the detector, to
ensure accurate acquisition. Press button
S1
to start the acquisition of the field
values and DL8 and DL9 will come on to confirm acquisition.
c) Rotate function switch
SW1 to Position 3
, and it is possible to read and/or modify
the
Pre-alarm threshold
. When the target dimensions pass the pre-alarm threshold
the Murena Plus will activate the fuzzy analysis of the signal.
Led
DL1
DL6
will display the level of the target dimensions, 3 led on indicating 50%
of the maximum dimensions achievable (the dimensions of an average size man is
equivalent to about 50)
To Read
the pre-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 varies between 01 and 99 (
default of 20).
Murena Plus Curtain default is 10
.
To Modify
the pre-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
minimum recommended 5
. During
normal operation the value of the pre-alarm threshold must not be higher the
value of the minimum target dimension threshold.
