Duemmegi Contatto ModLC-WM Manual

ModLC-WM / WM-P: ambient light regulator
module with integrated sensors for Bright-
ness and Presence (-P version)
ModLC-WM module allows to transmit, over the Contatto
bus, the ambient brightness value detected by the sensor
integrated inside the module itself. This module provides a
PID algorithm for the automatic regulation of the ambient
brightness and some SMART modes, thus allowing to con-
siderably simplify the programming of the MCP controller
when realizing these kinds of applications. ModLC-WM-P
also features a built-in presence sensor.
ModLC-WM module can thus be well applied in the bright-
ness regulation of offices, stores and open spaces, allow-
ing to develop applications complying with the new
European norms about the energetic classification of the
plants (European Norm EN 15232).
ModLC-WM module is suitable for wall mounting; the sen-
sor detects the light reflected by the surface under it (for
instance the floor or a desk). The special integrated sensor
has the same spectral sensitivity of the human eye.
The module features a 7-way removable terminal block for
the connection to the Contatto bus and, if required, to
presence sensors (e.g. DUEMMEGI SRP) that must works
in parallel connection with internal sensor (if -P version).
ModLC-WM module, for its operations, can work only in
systems equipped with MCP XT or MCP 4. The housing is
plastic material with IP20 protection degree.
Note: this technical sheet applies to ModLC-WM and ModLC-
WM-P equipped with FW 2.5 or higher.
Address programming
ModLC-WM module takes one input address and, if en-
abled, one output address with the same value; the ad-
dress has to be assigned by the FXPRO programmer
through the proper programming cable inserted in the con-
nector placed inside the module.
Wiring diagram
The following schematic diagram shows the connections to
the Contatto bus.
The input (IN) may be used for the connection to one or
more presence sensors that, for -P version, will work in par-
allel connection with the internal sensor; the contacts of
these sensors, which must be potential free, must be con-
nected between the terminals +COM and IN.
Anyway, take in account that terminal 1 is a 24V voltage
output to supply the external contact, which, as said before,
must be potential free. The terminal 2 is the digital input of
the module and can be also activated by a continuous posi-
tive voltage, referred to 0V, inside the range 10 to 30V.
