Code table Status sensors (no. 9)
The status of the 4 light sensors is visible with this communication object. If a light sensor provides a
changed sensor value within a time of 5 seconds, the DALI Light Controller assumes that a light sensor is
not connected or the light sensor is defective.
A missing sensor signal is indicated by a 0 in the corresponding bit of the communication object Status
Sensors (no. 9).
The lowest bit (bit number 0) indicates the status of light sensor A (1). The highest bit (bit number 7)
indicates the status of light sensor H (8).
The following code table shows you the status of all light sensors based on the hexadecimal or decimal
values read from the communication object Status Sensors.
