LCN-GBL
Local Control Network - building controls in perfection

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.

Lx
Relation between Lux values and LCN numerical values:
LCN value
1 - 100.000 Lx = 1 - 1152 (LCN value)
conversion formula
(LCN/100)
Lx = e
bzw. LCN = ln(Lx) * 100
