ART . 20046821 - LOAD MANAGEMENT MODULE
The SimpleHome module 20046821 can be used to measure the power absorbed or produced over a single-
phase system with a voltage of 230 Vac. By installing this module in the SimpleHome system and connecting it
to the BUS, it will be possible to view the power value measured by the module on one of the supervisors (e.g.
Planux Manager, Serial Bridge, Minitouch, etc.). In addition to simply recording measurements, a list of loads can
be set for the disconnection of digital outputs on the SimpleHome modules (connected, for example, to controlled
sockets) if the recorded consumption value exceeds the limit set during programming. This application is useful
for ensuring the energy supplier's thermal switch is not triggered. The outputs are disconnected in accordance
with the specified order. After a certain period of time (which can be programmed), the module will attempt to
reactivate the outputs in reverse order. An absorption value can be set for each of the loads entered on the
control, so that reconnection only occurs at the very moment in which the power entered for that load is available
on the system.
A SimpleHome system output can be set so that when the load control intervenes, the output is activated to
signal excessive consumption and indicate any downtime caused by the disconnection of the outputs. It is also
possible to set an instant disconnection setpoint on the module; when this is exceeded the module will deactivate
all specified outputs instead of disconnecting each output one-by-one with the relevant control.
The module can be used to store information for the metering of recorded energy, and functions as a log. The total
sum of the recorded power values can be viewed by entering several devices on a single system. For this function
to work, a compatible supervisor must be fitted to the system.
Operation example:
Timed disconnection limit: 3500 W. Instant disconnection limit: 4000 W. Load 1: consumption 800 W,
disconnection time 5 minutes. Load 2: consumption 1500 W, disconnection time 5 minutes. When 3500 W is
exceeded, the module will begin by disconnecting load 1,
followed by load 2. When the set disconnection time has elapsed, the module will attempt to reactivate the load
disconnected most recently. If in that instant the module reads a value of 2500 W it will not reactivate load 2,
which has a consumption of 1500 W, to avoid exceeding the set disconnection limit (3500 W); it will, however,
reactivate load 1 as the consumption of this load will not cause the limit to be exceeded. The module will then
only reactivate load 2 when sufficient power is available on the system.
Tolerance and delta values must be taken into account, as they may cause the readings to vary by approximately
100 W.
