If the regulator is on, upon receiving a short pulsation
it will turn off.
A short pulsation refers to any pulsation lasting be-
tween 50 ms and 400 ms.
LONG PULSATION:
If the regulator is off, upon receiving a long pulsation it
will turn on using the minimum level of light; then it will
increase it until the pulsation stops, or until it reaches
the maximum level of light. If the regulator is on, upon
receiving a long pulsation the regulation direction will
reverse: if the level of light has increased up to a cer-
tain point, it will diminish, and vice versa. Whenever
the maximum level of light is reached during a long
pulsation, the regulation will stop in the maximum
level, even if pulsation continues. However, when the
minimum level is reached, it does not stop and it starts
increasing.
A long pulsation refers to any pulsation lasting for
more than 400 ms.
