PIR motion detector and light sensor for the I-connection in glass design
The LCN-GBL is an indoor PIR motion detector with integrated light sensor in the LCN-GT
series design. Optionally a humidity sensor LCN-EFS can be inserted.
The PIR motion detector works on the passive infrared principal. The changes in human
body heat radiation are detected.
The integrated light sensor covers a very large measuring range of 5 decades
(1-100.000Lx). The measured value can be used for light dependant control or for a
constant light regulation.

Connection
The LCN-GBL is suitable for connecting to the I-ports from
LCN-UPx, -SH, -SHS, -LD and -HU Serial number 120C05
(Dec. 2008) or later. The connecting cable to the LCN module
can be optionally extended up to 50 m with an LCN-IV - see
LCN-GBL, mounting plate, 2 screws (3,2x25)
& I-connecting cable.

(www.LCN.de / downloads).

How the light sensor functions:
After connecting, the LCN-GBL will de detected automatically and its measured value
transferred into the second controller variable (R2-Var) of the module. You can control the
value in the status window of the LCN-PRO. The configuration of the light value is carried
out in regulator 2 and/or with the 4 thresholds - see also page 4. For the last mentioned, the
R2-Var must be copied into the T-Var. The measured light values will be logarithmised, to
make it better for presenting the large value range.

How the PIR motion detector functions:
When an object is detected, the connected module sends out a long command
(standard: key B4). The long command will only be sent once, even when the movement
lasts a very long time.
5 seconds after the movement has ended the LCN-GBL triggers off the release command.
If the movement lasts longer, the release command will come approx. 8 seconds after the
last movement.
Detecting range:
When needed four LCN-GBL´s can work on one module: for this every LCN-GBL must be
coded, so every PIR motion detector works on ist own key. Here you have to seperate the
marked circuit paths (see table and illustration on page 4).

Letting the PIR motion detector work on other keys
Through separating the circuit path, the light sensor will be
deactivated. Then there is only one light sensor per
module active!
The key B4 is reserved with the integrated motion detector.
As a result the fourth threshold cannot be used.
Additionally a binary sensor LCN-B3I can be connected to
the same LCN module.
The LCN-BT4H/-BU4L (4-way binary sensors) cannot
always be used on the same module.
(check the key mapping first!)
thumb rule: maximum 4 LCN-GBL´s on the I-connection
are allowed!

installing/Uninstalling
The LCN-GBL is delivered in a housing,
which can be installed on a light outlet box
(35 mm, e.g.: ). An
additional screw fitting is possible and often
useful.
when installing on ceilings: Check for a safe
fixing in every case, to avoid an injury
caused by a fallen off glass plate!
After screwing the installing frame on to the
wall and plugging in the I-connection, the
sensor housing from the LCN-GBL is simply
snapped on to the installing frame.
To uninstall the sensor, a screwdriver is
placed into one of the both (opposite from
one another) uninstalling openings and with
a light lever movement, the sensor housing
removed from the installing frame.

Installing the optional humidity sensor LCN-EFS
An optional humidity sensor LCN-EFS is available to be subsequently built into the LCN-
GBL. The use of the built in humidity sensor LCN-EFS is only possible with modules using
firmware 160A... (Oct. 2012) or later. To do this, the jumper bridge must first be removed
before inserting. A maximum of one further LCN-EFS may only be operated on one
module.
For later installation, please open the service cover on the LCN-GBL and stick the LCN-
EFS humidity sensor in. For a correct installation, the tick sign on the circuit board must be
visible.
