Commissioning
The reaction to another telegram value is described in the following telegram:
Value Bit 1 Bit 0
0 0 0
1 0 1
2 1 0
3 1 1
Both the following parameters are enabled with parameterised 2 bit
control:
Brightness while object value = 3 (forced operation = active, ON)
Options: 100 % (255)/99 % (252)...2% (5)/1% (3)/0% (Off)
The brightness value used to control the output when it is forced ON
is set with this parameter.
Setting force operation
after bus voltage recovery
Options: inactive (value 0)
switch off by force (value 2)
switch on by force (value 3)
This parameter determines which value the object Forced operation is
assigned, with bus voltage recovery.
•
inactive: The output is enabled after bus voltage recovery and is
no longer subject to forced operation.
If parameterised constant lighting control was activated before
forced operation it will be active.
•
switch off by force (value 2): The output of the Light Controller is
forced OFF and remains inhibited until forced operation is again
deactivated.
•
switch on by force (value 3): The output is switched on and
controlled with the parameterised brightness for forced operation
in the ETS.
State Description
If the object Forced operation receives a telegram with
Free
the value 0 (binary 00) or 1 (binary 01), the output is
enabled and can be actuated via different objects.
Free
If the object Forced operation receives a telegram with
the value 2 (binary 10), the output of the Light
Controller is forced OFF and remains inhibited until
forced operation is again deactivated.
Forced Actuation via another object is ignored as long as
OFF
the forced operation is active. Commands are run in
the background and the end values are saved.
After deactivation of forced operation the brightness
value which is continuously processed in
the background is set.
If the object Forced operation receives a telegram with
the value 3 (binary 11), the output of the Light
Controller is forced ON and remains inhibited until
forced operation is again deactivated.
Forced Actuation via another object is ignored as long as
ON the forced operation is active. Commands are run in
the background and the end values are saved.
After deactivation of forced operation the brightness
value which is continuously processed in
the background is set.
