L-DALI User Manual 283 LOYTEC
Version 5.2 LOYTEC electronics GmbH
nviSBOverride, nciOverrideValue: The nviSBOverride network variable of type
SNVT_switch can be used to switch on/off override mode. If the override mode is
active, the sunblind output is set to the value of the configuration property
nciOverrideValue (type SNVT_setting).
8.2.9.6 Museum Mode
For the museum mode of the constant light controller (see Section 8.2.8.11) a sunblind
controller must be linked to the constant light controller.
8.2.9.7 Output and Feedback
The L-DALI sunblind controller supports actuators with a control input of type
SNVT_sblnd_state (see Figure 225) as well as sunblind actuators with a control input of
type SNVT_setting (see Figure 226).
The configuration property nciDriveDelay defines the delay which the sunblind controller
waits until it updates its outputs. If different drive delays are configured for the different
sunblind controllers, the sunblinds will not drive at the same time avoiding a power peak.

The output network variable nvoSBStateFB can be used by e.g. a SCADA system to display
the current state of the sunblind. It includes status information from the sunblind controller,
which is merged with feedback information from the sunblind actuator, if available.
The event state (e.g. maintenance mode, rain condition, wind, etc) of the sunblind controller
is reported in the output network variable nvoSBMode.
