LIGHT LEVEL FEATURE
The Light Level feature holds lights off upon initial occupancy if adequate
ambient light exists. It will not turn the lights off if they are on. The default
setting is for maximum, meaning that even the brightest ambient light will
not hold the lights off.
Notes on Functionality
•
Avoid mounting the sensor close to lighting fixtures
•
Adjust during daylight hours when ambient
light in the area is at desired level.
•
Light Level cannot be enabled while Test Mode is active. Either
wait for Test Mode to expire or select any of the other Time
Delay settings before enabling the Light Level feature.
•
The ultrasonic occupancy indicator LED is disabled when the
Light Level feature is enabled. LED will also flash periodically
to indicate the sensor has Light Level enabled.
•
Light Level settings are only saved in the event of a
power loss. Disabling Light Level and then reenabling
it will not return it to previous settings.
•
If Test Mode is enabled after Light Level has been set, Light Level
functionality will cease to function throughout the duration of Test
Mode. When Test Mode period expires, the Light Level functionality
will resume, even if the Dip Switches remain set to Test Mode.
Setting Light Level
1. Make sure Test Mode is not active.
2. Toggle the state of the sensor, by briefly pressing the Light Level
button, to include or exclude the lighting load from the light
level calibration. Open the Front Cover and locate the LIght Level
pusbbutton. See Sensor Adjustment.
3. Press and hold the Light Level button between 2s and 5s. The green
LED will be ON showing 2s is reached and then be OFF showing 5s
has passed.* The sensor enters setup mode, as indicated by the
rapidly flashing LED. The LED will flash throughout the setup process.
Occupancy indications from the LED is disabled during setup.
4. Move away from the sensor to avoid interference with light level
detection. The sensor measures the light level for a 10 second period,
then averages the readings and automatically sets the level that will
be used as the new setting. The sensor will hold lights off when the
ambient light exceeds this setting.
