2.4
Controller’s operation
The default state of the controller is the standby state when no inputs are active. In this state dimmable
lamps may be either off or on with gentle backlight; non-dimmable lamps are off. The controller is
awaiting a signal either at the DIS port (which will disable the controller and turn all the lights off) or
from any of the UP /DN inputs (which will start the lighting sequence).
2.4.1
Turning lamps on
The ‘turning-on’ phase consists of turning on consecutive lamps:
from the first to the last, if the signal came from the UP input;
from the last to the first, if the signal came from the DN input;
If another signal appears at the other input while the lamps are being turned on, the sequence will also
start from the other side.
If applicable, the Master lamp is turned on first, either before or at the same time as the first lamp in the
sequence. The smoothness of the turning on of the lamps can be set within a broad scope by setting the
Smoothness
parameter: from sharp to very smooth turning on.
2.4.2
Lights on
When the lights are on, they remain on for a time predefined by the
On time
parameter. The time
extends when a new signal appears at any of the inputs.
2.4.3
Warning
When the time determined by the
On time
parameter passes, either the lights turn off (if the
Number of
warnings
parameter is set to 0) or the controller enters the warning phase (if
Number of warnings
is
greater than 0). The warning phase informs the user that the lights are about to turn off. The phase
consists of a number of ‘warning–waiting’ cycles consisting of the warning and awaiting the user’s
reaction. The warning can be either a short dimming of all lights (a ‘blink’), alternate dimming of the
even and odd lamps (a ‘flicker’) or a dimming of one or two lamps moving back and forth (pendulum
effect).
2.4.4
Turning lamps off
Turning off the lamps is defined as dimming the lights from the full brightness to the backlight level
brightness.
The ‘turning-off’ phase is reversed with respect to the turning-on phase: the lamps are turned off either
as they were turned on or in the reverse order (depending on the setting of the
Off direction
parameter). The Master lamp (if set) is turned off last. The smoothness of the turning off is the same as
in the case of turning on, and set with the
Smoothness
parameter.
