0-10 volt dimming ballast and the #EZR option per
your Lighting Layout and connect to AC power

luminaire.
UL2F-EZR Module
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.
Ordering Guide:
The DL System is the combination of the ULM-EZR Module (UF2F-EZR) and a Lightolier recessed fluorescent fixture* with a 0-10 volt dimming ballast and
the #EZR option. This option includes integrated RJ45 receptacles and a 12 foot long CAT5 cable.
The Module and luminaire need to be ordered separately.
ULM-EZR Module: Catalog Number UL2F-EZR
DL System Fixture: Specify a Lightolier recessed fluorescent fixture* with a 0-10 volt, 2 wire, dimming ballast and then add suffix #EZR

footcandle reading.
Adjust to desired footcandle level by rotating the sensor in the face of the
ULM-EZR Module.
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)
To get MORE light on desk from the
luminaire, close aperture by rotating
it counter-clockwise.
The lamps will get brighter.
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 LESS light on desk from
the luminaire, open aperture
by rotating it clockwise.
The lamps will dim down.
