51 TR80 - Installation and Operation Guide
3. 11. 1 Light Group 1 configuration
Set “number of scenes” to 0, to disable scene selection/activation for this group.
3. 11. 2 Light Group 1 control
‘Level Feedback’ and ‘Last Scene Feedback’ information typically comes from the DALI64 sen-
sor. When the user enters the setting mode for any light group these are the values that will be
displayed initially, and the user will start setting (incrementing / decrementing) from these val-
ues.
The scene settings 0-15 correspond to user scene selections 1-16.
If the DALI64 sensor is connected to port 2, the TR80 wall module will read the ‘Level Feedback’
and ‘Last Scene Feedback’ directly, without any dependency on a master controller. If DALI64
sensor is connected on port 1 (or a different lighting control system is employed) the master
controller will need to provide this information to the wall module.
The ‘New Level’ and ‘New Scene’ registers are used to convey user commands to the master
controller. These will normally be at an invalid value of 32767. If the user selects a new light
level or a new scene on the wall module, the relevant register will contain the newly selected
value. But as soon as it is read over Modbus, it will automatically revert to the invalid value of
32767. This scheme ensures all user commands are registered as a change-of-value and can
be acted upon by the master controller.
If a DALI64 sensor is connected to port 2, the TR80 will directly send light level or scene recall
commands to the DALI64. There is no need for the master to route values in that case.
