BR100 is an accessory accepting up to
4 LCD W boards.
Chapter 19: BR100 Kit and LCD W (optional) signal remoting-device
LCD W is a Led and
display module
allowing the
c o n s t a n t
monitoring of
the BM M
signal to
which it is
associated.
This system of remoting the signal levels of the beams, is made of a Led/display module (LCD
W) for any couple of beams, to be contained into the BR100 housing.
Thanks to this system, it is possible to monitor constantly from 1 up to 4 couples of BM M.
On the front of BR100 module, for any couple of beams to monitor, there are:
•
the LCD W module for vizualising the signal
quantity received, expressed in Volt (the
display visualizes the units, the Led bar
visualizes the decimals). The value
shown is the same given by the TP
terminal (Test Point) of the receiver to
which it is coupled
• a yellow Led (FAIL) is especially
appointed to the Disqualification
indication
•
a red Led (ALARM) indicating the alarm
condition (it follows the condition of the
receiver red Led)
•
a green Led (STATUS) visualizing the
signal quality (it follows the condition of the
receiver green Led)
There also is a key-block which must not be
connected (for future uses)

The supplying of the BR100 panel must be separate from the beams supplying in order to
avoid that a possible short-circuit in the supplying line of the panel can cause the break of
the supplying to the beams. To this purpose, use the fuse-holder with its 500 mA fuse
given within BR100 panel.
