ULM-EZR module sensor placement guidelines:
Before adjusting sensor settings, check to make sure they have
been installed in accordance with the following guidelines:
Sensor SHOULD be located
• Between 6-10’ away from window
• Over work surfaces
Sensor should NOT be located
• Over very dark surfaces (e.g. dark carpet or furniture)
• Over highly reflective surfaces (e.g. polished floors or tables)
• Outside the daylit zone (typically beyond 15’ from window)
NOW, LIGHTOLIER makes DAYLIGHTING as EASY as
1-2-3
Install Lightolier recessed luminaires* which include a
0-10 volt dimming ballast and the
#EZR
option per
your Lighting Layout and connect to AC power
as you normally would any recessed
luminaire.
Install a ULM-EZR module in the ceiling, positioning it 6 to 10 feet from windows
and over a work surface (it must be within 10 ft of a luminaire).
Using the low voltage plug-in 12' long CAT5 cables provided with the
luminaires*, connect the luminaire and ULM-EZR module.
An additional CAT5 cable will be provided with each luminaire* to plug in
additional luminaires* as in a daisy chain. Up to 20 luminaires* can be
connected to a single ULM-EZR module.
ULM-EZR modules can be moved or added at any time merely by plugging or
unplugging the CAT5 cables.
Both ULM-EZR modules and fixtures have proprietary RJ45 dual receptacles for
the CAT5 cable with RJ45 plugs.
When there is no daylight, place a lightmeter on the work surface and take a
footcandle reading.
Adjust to desired footcandle level by rotating the sensor in the face of the
ULM-EZR Module.
The sensors are factory pre-calibrated to 45fc on the horizontal,
assuming standard reflectances (80/50/20), ceiling heights
(8-10’) and work surfaces (2.5’).
To return to the default setting, rotate the aperture until it ‘clicks’
back into place at the mid-point.
To get MORE light on desk from the
luminaire, close aperture by rotating
it counter-clockwise.
The lamps will get brighter.
To get LESS light on desk from
the luminaire, open aperture
by rotating it clockwise.
The lamps will dim down.
