Easysense With Multiple Sr Drivers (1:N Application) - Philips EasySense Design Manual

EasySense with multiple SR drivers
(1:N application)
May 2016
When a group of luminaires is in the same daylight
condition and needs to be operated at the same
level, it is possible to use one sensor to control
multiple luminaires. When EasySense is connected
to multiple Xitanium SR drivers with an enabled DALI
power supply, the maximum number of connected
drivers is limited to four. Each SR driver provides
approximately 55 mA of current on the DALI bus and
EasySense is limited to 250 mA.
EasySense sends commands to all connected
drivers (using broadcast command); it does not
have capabilities for addressing individual drivers.
The light commands are sent as a broadcast
command, so occupancy-/daylight-based lighting
control and task tuning operate the same on all
connected drivers. The readout of energy
information from the driver will not function.
The energy readout of multiple drivers is foreseen
for future sensor generations.
Warning:
i
Please note the DALI power supply can only be
turned on/off on the SR driver through
MultiOne configurator. For this application,
please also make sure all drivers that are
connected to the sensor have the same wiring
polarity. SR Drivers are shipped with the power
supply on as default.
