passing cloud), the detector has been designed with a delay of 10 s for light activation, i.e. it
will ignore any movement within the 10 s delay time. The red LED will be on steady as an
indication, but the detector will not react within this timeframe.
The ambient light level changes from dark to bright: if the ambient light level exceeds the
“Switch ON Lux value” for 5 min, there are different reactions according to the value of the
“Lighting delay time” parameter:
o
If Lighting delay time > 5 min: the light will be automatically switched off after 5 min.
o
if Lighting delay time < 5 min: the light will be automatically switched off when the set time
expires, if no movement is detected within the 5 min. timeframe. But if any movement is
detected within the 5 min timeframe, the time will be reset upon detection and the light is
switched off after 5 min.
13.9 2-level (Standby Lighting) function
In Auto mode and when Output type
is set to “Dimming”, when the ambient light level falls below the
pre-set
“Switch ON Lux value”, the detector will enter into 2-level mode function automatically.
if
“Standby Time” is set to “Infinity”, the detector will enter into 2-level mode when the “Lighting
delay time” is expired. In this situation, if a movement is detected, the load will turn on with
the setting illumination (100% or the dimmed
value according to the setting of “Standby
brightness) and then turn off if movement is no longer detected and the
“Lighting Delay time”
has expired. It will be cycled until the ambient light level is higher than the
“Switch ON Lux
value
” and it lasts for 5min, then turns off and the detector resumes to Auto mode function.
if “Standby Time” is set to other position except for “infinity”, the detector behaviour is
basically the same as above mentioned, but the duration is according to the selected
“Standby Time” value.
If “Lighting standby time” is set to “disable” (OFF), the load will be off when the “Lighting delay
time
” is expired.
13.10 Constant light control
According to the changeable ambient light level, if “Constant light control” is set to Enabled, then the
load can dim to bright or dark automatically to match the “Preset setpoint” Lux value.
13.11 Alarm
The alarm function can be set to behave in the same way in case of switching on or off, or in a
different way depending on the event.
The Alarm output (Communication Object 18) can be locked using CO 17 (Lock alarm).
Options for
“Behaviour at switching ON (or OFF) lock by CO are “no reaction”, “switch OFF” and
“switch ON”.
The number of detected movements
(“windows”) within a time frame (“Duration”) can be set.
