Master / slave programming
Connection of a light sensor informs the TRIOS DALI
controller that daylight-linked regulation is required.
By assigning channels 1 and 2, it is possible to obtain a
'master / slave' circuit.The ‘master’ luminaires nearest the
window will automatically dim as daylight increases.
The ‘slave’ luminaires, installed further from the windows
where the daylight penetration is less, will also dim but
not to so low a level as the ‘master’ luminaires.When
adequate daylight is available the ‘master’ luminaires will
automatically switch off and the ‘slave’ luminaires will be
dimmed further. Maximum energy saving is achieved
whilst a balanced lighting level is constantly maintained
over the whole room.
Setting the required value
Fast setting, can be changed at any time; using IR remote
control.
Preparations:
Obscure the windows. Measure the artificial light level
(illuminance) with a lux meter.
If it is not possible to exclude natural light, measure the
illuminance of the natural light on the working plane
below the light sensor with the artificial light switched
off. If the value lies above the required level of
illuminance, the measurements must be made again after
nightfall
With the artificial light switched on, measure the
illuminance on the working plane.
Setting:
If an IR remote control or RC5 Push button interface
+ switch is connected:
Set the required value by pressing the channel buttons
(light up / dim). Five seconds after the time the last
button is pressed,TRIOS DALI records the new
illuminance level set as the required level.This level can
also be recorded a PRESET: up to four different PRESET
levels can be recorded for push-button selection.

Programming the master / slave circuit
Channel 1 on / off Master / slave luminaires switch on or off
Channel 1 up / down This function can be used to set the reference light level
of the master (regulation is switched off during this
process)
Channel 2 on / off No function in this application
Channel 2 up / down This function can be used to set the level of the slave
luminaire relative to the master luminaire.The level can
be set as identical, lower, or higher. Generally it will be
higher
