Legrand Energy Management

Every bit counts Making energy usage visible SOLUTIONS FOR THE DISPLAY OF ENERGY CONSUMPTION  AND LOAD CONTROL MANAGEMENT

Saving energy has never been  this easy With Legrand SCS control systems it’s easy to see how much gas and electricity a residence is consuming. With a few simple components, property owners can view energy usage data in a user-friendly format on a colour touch screen. 10 inch colour touchscreen A complete consumption and  energy production check-up The user can display on the touchscreen not only the consumption inside their home (power and gas), but also the energy and hot water output obtained by solar panels. With a few simple steps, the user can select the type of consumption that needs to be checked, the type of display (instantaneous or graphs), and the period (day, month, year).  3.5 inch colour touchscreen CONSUMPTION  DISPLAY 

Consumption display - Visualisation Visibility drives savings An aware user is one that saves - decreasing their impact on the environment and reducing their costs. Studies have shown that displaying energy consumption results in users changing their routines or correcting faults which result in savings of 10-15%! Dedicated icon of the mainscreen of the touchscreen Energy selection screen Power consumption screen Monthly power consumption graph Daily power consumption graph The consumption can be displayed on the touchscreen as instantaneous or cumulative data in graphical or table format to make interpretation easy. By setting tariff values it is possible to display the data in the form of costs. The energy data collection devices enable electricity and gas consumption to be displayed on the touchscreen. It is also possible to display the energy produced on site from solar thermal and photovoltaic systems.  UP TO 15%   SAVINGS

The energy data collection devices can be integrated directly on the BUS of the automation/temperature control system, or be part of a dedicated system, as shown on the diagram below. In this case a power supply will be necessary to power the BUS and touchscreen to display consumption levels.

This display shows consumption of power and gas as well as heating data. Using the power meters and the pulse counter interfaces, it is possible, when a photovoltaic or a thermal solar system is installed, to monitor how much power is being generated.

The data is displayed on the touchscreens through the SCS BUS. The processing and accounting functions are: ■  Instantaneous consumption of 3 lines maximum ■  Cumulative hourly consumption for the last 12  months, daily consumption for the last 2 years and monthly consumption for the last 12 years The above described functions are also valid to save the data coming from solar thermal and photovoltaic systems. The device is supplied with 1 toroid and corresponding connection cable; it is suitable for installation inside distribution boards and switchboards and requires the space of 1 DIN module.

Load control management The end of the black-out The load control management system manages the maximum power used, by automatically disconnecting appliances in a prioritised order when a predetermined electrical consumption level is reached. The system:  ■  manages up to 63 loads ■  displays on touchscreens the instantaneous and  cumulative hourly, daily and monthly consumption of the controlled phase. In addition, the actuator with sensor, enables measurement of the actual consumption of the controlled load Energy management iconon the touchscreen Diagnostic icon Consumptiondisplay icon Load controlmanagementicon Power consumption screen (instantaneous/cumulative) Monthly power consumption graph Controlled load  consumption display screen Controlled loads  screen ■  Appliances or circuits can be disabled or  re-enabled through the touchscreen along with setting appliance priorities ■  The touchscreen enables users to check that the  electricity loads are operating correctly through measurement of any earth leakage ■  The actuation and control devices occupy only  one DIN module each therefore optimising space on the distribution board ■  By configuring the actuators of the load control  system in automation mode, it is possible to use the touchscreens to set the time delays for the activation of the loads at set times

Load control management Operation Using the external toroid, the central unit measures the power used by the loads connected and compares it with the value preselected during the installation (using the configurators it is possible to select powers between 1.5 and 18kW, with tolerances up to +/- 20%).  An actuator is associated to each appliance being controlled. The actuator receives the information from the central unit and disconnects the load from the network in case of overload. The disconnection sequence of the actuators is defined during the installation. This can be achieved by using a simple configuration operation to be carried out on the devices themselves. The central unit gives the possibility of managing up to 63 priority levels, and a number of devices depending on the available supply current. In the example shown, the oven, the microwave oven and the washing machine represent the loads controlled using actuators, while the refrigerator, the operation of which should not be interrupted, is connected to the socket without actuator. In case of overload, the first device that disconnects is the  Power meter Electric distribution board Mains Mains NOTE: Inside the electric distribution board the central unit for load management and actuator 16A are installed (see next pages) Central unitfor loadmanagement SCS BUS Doublepowerpoint Doublepowerpoint Doublepowerpoint Doublepowerpoint Non-controlled load Controlled load withpriority 1 Controlled load withpriority 2 Controlled load withpriority 3 one considered the least important by the user, in this example the oven, whose actuator has configurator no.1. The microwave is on the other hand the most important device, and the corresponding actuator has configurator no.3. This load therefore only disconnects after the oven and the washing machine. The user can reactivate the disconnected device at any time using the actuator pushbutton or the touchscreen. In this case, if the overload condition still exists, the central unit will enable the operation of the selected load, but will disconnect the subsequent loads starting from the least important, until the overload situation is resolved. The operating status of loads is notified both by the actuators and the touchscreens. By configuring the actuators of the load control management system in automation mode, it is possible to use the touchscreen to set the time delays for the activation of the loads at set times.
