Functional behavior
0-10V Interface
The minimum output voltage is
MinVoltageLevel
(default
1.0V); the maximum output voltage is
MaxVoltageLevel
(default 10.0V).
Dimming below
MinVoltageLevel
or above
MaxVoltageLevel
is not possible.
Level and ramp percentage levels refer to the interval
between
MinVoltageLevel
(1%) and
MaxVoltageLevel
(100%).
An output level of 0% equals OFF state.
Switches only
Short click (<0.7s) on “I” button: Light comes ON and
brightens to most recent dimming value stored before
device was switched OFF or to the
FixedOutputLevel
value
(default=75%) if
EnableFixedOn
=enabled (default=disabled).
If a light level sensor is linked, then light will be set
according to its input (see below). The minimum initial light
level in this case is
MinVoltageLevel
(default 1.0V).
Double click (<0.7s) on “I” button: Light is switched ON at
MaxVoltageLevel
(default 10.0V).
Short click (<0.7s) or double click (<0.7s) on “0” button: The
current light level is stored, light is dimmed down to
MinVoltageLevel
and then switched OFF.
Ramp up (
RockerSwitchOnSpeed
) and ramp down
(
RockerSwitchOffSpeed
) speeds for rocker switch operation
are configurable (default 20% per second).
Press and hold “I” / “0” button: Light is brightened / dimmed
until button is released or
MinVoltageLevel
/
MaxVoltageLevel
is reached.
Ramp up (
RockerDimUpSpeed
) and ramp down
(
RockerDimDownSpeed
) speeds for rocker dim operation are
configurable (default 20% per second).
Rocker-based dimming can be disabled by setting
RockerDimEnable
= OFF. In this case light will be switched
ON / OFF immediately upon pressing the “I” / “O” button.
Light can be switched OFF automatically in absence of a
linked occupancy sensor if no user (switch) action occurs
during a period defined by
RockerSwitchAutoOffTimer
.
This feature can be disabled by setting
RockerSwitchAutoOffTimer
= 0. This feature is automatically
disabled if an occupancy sensor is present. In this case,
automatic switch OFF of the light will be performed based
on the input from the occupancy sensor as described below.
Occupancy Sensors only – Auto Off Timers
If at least one sensor detects motion, Light level is set to
Auto On Light Level
(default 100%). Default setting
(
OccAutoOn = disabled)
is disregarded in this scenario.
If none of the linked occupancy sensors reports motion for a
period defined by
Auto Off Time1
(default 10min) then light
is set to
Auto Off Level 1
(default 50%) and timer 2 starts
with Auto Off Time 2 (default 5min).
Auto Off Level 1
is
always relative to the current light level when timer 1 did
elapse. For instance, if the Auto On Light Level had been
changed to 80%, the resulting absolute light level for timer 2
is 40%, cutting the level in half (with
Auto Off Level 1
=50%
= default). If Timer 2 has elapsed, the light level will be
switched to
Auto Off Level 2
(default 0%).
Any motion detected by any linked occupancy sensor will
reset both timers and the light level back to timer 1 level.
Ramp up (
SensorRampUpSpeed
) speed for Auto ON and
ramp down (
SensorRampDownSpeed
) speed for Auto OFF
are configurable (default 20% per second).
Occupancy Sensors and Switches
Light can be switched ON / OFF manually, function as
described above. Time-based automatic switch OFF (as
defined by
RockerSwitchAutoOffTimer
) is always disabled if
at least one occupancy sensor is linked.
While no presence is reported by any of the linked
occupancy sensors and no switch input is received, both
Auto Off Timers will act as described above. Any input will
reset both Auto Off Timers.
Light will be automatically turned back ON to timer 1 value
if occupancy is reported within the
VacancyGraceTimer
period (default 45s) after such Auto OFF event even if the
Auto ON function is disabled.
The system can also be configured (
OccAutoOn =
Enabled)
to automatically switch ON the light as described above.
