With or without automatic relinquish
: If automatic relinquish is active any manual
override will be automatically relinquished when the room becomes unoccupied.
Manual-On/Auto-Off Mode
The MANUAL_ON_AUTO_OFF mode is a variation of the PRESENCE mode. However,
in this mode the constant light controller does not switch on the lights, when the room
becomes occupied. Rather, it switches the lights to the unoccupied level (see Section
8.2.8.8) when the room becomes unoccupied, using
nciHoldTime
similar to PRESENCE
mode.
Lights can be switched on (or off) using
nviCLOverride
or
nviCLSetting
or via some other
DALI master (e.g. a DALI push-button).
Ambient Mode
The AMBIENT mode is used if effect lighting (e.g. lights in a shop window, facade
lighting, floor lights etc.) has to be switched on or off depending on a measured light level.
Lights are switched to the value
nciPrimeVal
when the
nviLuxLevel
is below
nciLuxSetpoint
and to the unoccupied level (see Section 8.2.8.8) when
nviLuxLevel
is higher than
nciLuxSetpoint.
Updater Mode
The UPDATER mode has to be selected when a DALI light/occupancy sensor with constant
light controller functionality is installed on the DALI network. In this mode no light level
computation is performed. The controller simply forwards the parameters to the DALI
constant light controller and retrieves lamp setting from the DALI light sensor.
In general, LOYTEC does not recommend using UPDATER mode. Wherever possible use
REGULATOR or CONTROL mode instead and use DALI sensors only as lux level and
occupancy information source via the corresponding sensor objects. These modes allow
improved influence of the constant light controller’s parameters via the fieldbus side.
8.2.8.4 Prioritized Control
The network variable input
nviCLOverride
can be used to override the constant light
controller algorithm. Valid (
.state
=0/1) values received on this inputs are directly passed to
the
nvoLampValue
output.
Similar an override is possible via the network variable input
nviCLSetting
when setting the
.
function
field to SET_OFF or to SET_STATE. When using SET_STATE the value of the
.
setting
field is directly passed to the
nvoLampValue
output.
When internal CLC bindings are used to control DALI groups an override can also be
performed using a DALI push-button device controlling the same groups as the constant
light controller (see Section 8.2.8.9).
To return to automatic mode the following options exist:
When the network variable input
nviCLOverride
was used to override the constant light
controller, set the
.state
field to -1 (invalid).
Set the .
function
field of
nviCLSetting
to SET_ON.
When using one of the modes with automatic override relinquish (xxx_AUTO or
xxx_BEDROOM) the constant light controller will return to automatic mode when it
changes its state to unoccupied.
