6.3. ActiDIM mode
The ActiDIM operating mode is a stand-alone dimming system that simulates astronomical behaviour to provide
energy saving without the need to wire in a control line.
The automatic dimming algorithm controls the times at which a change of light level has to take place. It takes as a
reference the average night time duration point, calculated based on the average of the last three nights. The duration
of each night is defined as the time measured from when the street lighting is switched on to the time it is switched
off.
NOTE:
When the lighting is switched on for less than 4 hours (for example, to carry out maintenance tasks or during power outages) and in
cases where it is on for more than 20 hours, the control gear does not memorise that period as a ‘night’ and therefore does not take
it into account when applying the ActiDIM calculation algorithm.
This system is able to configure different dimming profiles, selecting up to maximum of 9 levels, their value, the
duration of the transitions and the changes between them.
6.8. ON/OFF mode
The driver can be configured in ON/OFF mode where no type of regulation is required.
If the user configures the driver with an output current below 350mA by means of the AOC functionality, the driver will
enter ON/OFF mode by default and no type of regulation will be allowed.
