Planning and application
If it has been set in the parameters, the Room Controller can continue to
function normally on failure of the bus voltage and the functions in the room
are maintained.
Example: Conventional push buttons are connected to a Room Controller
via binary input modules. The Room Controller controls the
lighting in the room. On bus voltage failure, the lighting can still
be operated because the Room Controller is not supplied by the
bus.
On bus voltage failure, the constant lighting control of the Light Controller
Module LR/M 1.6.1 is deactivated. The current setpoint value of the constant
lighting control will remain unchanged.
Reaction on bus voltage recovery
Any output brightness can be set in the parameters. The setting
"unchanged" is likewise possible. Further information and parameter settings
you will find in in the description of parameter window "general".
Reaction on supply voltage failure
The supply voltage has failed if both the 115/230 V AC supply and the 12 V
DC auxiliary supply of the Room Controller have failed. The Room Controller
has no function in this case.
The Light Controller Module LR/M 1.6.1 and the Switch/Dim Actuator Module
SD/M 2.6.1 switch the control output to 100% (high resistance). The state of
the relay output remains unchanged.
The Universal Dim Actuator Module UD/M 1.300.1 switches off the output.
Note: Some stored preset and scene values are lost on failure of the
supply voltage. They are overwritten by the parameterised
default values.
Reaction on supply voltage recovery
The behaviour of the outputs is identical to the behaviour on recovery of the
bus voltage. It can be parameterised for each output. It is possible to restore
the brightness value prior to the supply voltage failure.
The constant lighting control of the Light Controller Module LR/M 1.6.1 is
activated if this function is enabled.
After programming, the device behaves in the same way as after bus voltage
recovery (see above).
The current setpoint value of the constant lighting control (Light Controller
Module LR/M 1.6.1) will remain unchanged.
