LED signals according to the status of the load control central unit:
Device status LED
Normal operation (below threshold with all loads enabled) GREEN
Current threshold exceeded RED
System not acquired ORANGE
Current system acquisition Flashing RED 100 ms/100 ms
BUS problem (BUS voltage insufficient, or voltage drop detected) Flashing GREEN 500 ms/500 ms
Installation error (230 Vac not detected) Flashing RED 100 ms/900 ms
Configuration error ORANGE flashing irregularly on GREEN
Not configured ORANGE flashing 128 ms/128 ms on GREEN
Procedure for the deletion of the cumulative energy data:
Load control actuators acquisition
MQ00360-c-EN 09/06/2014
Load control central unit
Once the installation stage has been completed, the central unit must acquire the
actuators on the bus; unless this operation is carried out, the device will continue
signalling lack of information (steady orange LED), and no load control function will be
carried out.
The procedure for the acquisition of the actuators on the BUS is as follows:
1. Press and hold down the button; after about 10 seconds, the red LED will light up;
release the button.
2. The red LED flashes quickly and the central unit interrogates the system to identify the
actuators installed.
3. Once the procedure has been completed, if no actuators have been found the
acquisition failed notification remains active (orange LED on steady), otherwise the LED
turns green, and the central unit starts operating correctly.
The procedure for the acquisition is inhibited if the central unit is not installed correctly
(voltage on the bus too low, or no 230V), or if an overload is present; it is therefore only
possible to complete the acquisition procedure if the LED is steady orange (installation
correct but no actuator acquired), or steady green (system already configured and actu-
ators acquired).
If the supply voltage is insufficient (below approximately 21V), the central unit will cause
the green LED to flash to signal the installation error: the device will work properly, but
will not guarantee correct saving and recovery of data in case of BUS failure.
1. Press and hold down the button; after about 10 seconds, the red LED will light up; keep
on holding down the button.
2 After another 10 seconds, the orange LED will flash quickly; release the button.
3. All the cumulative energy data are reset.
