1) Variable Voltage Control
An analog 0-10V active dimmer may be connected to the two wires to control the light output of the
fixture. Multiple lights may be connected to the same dimmer, as long as the maximum current
rating of the dimmer is not exceeded.
The dimmer must be capable of sinking 0.5mA per light. Light output will vary approximately
linearly with control voltage, with 10V corresponding to 100% light output.
Note: If the control voltage exceeds 10V the light output will not increase beyond the normal
maximum brightness, but it is recommended that the control voltage be limited to under 15V.
Example Application of Adjustable Brightness Using Active Analog Dimmer
2) Step dimming
Simply shorting the two wires together will cause the light to dim to a low level, as shown below.
When this is done, the light will dim down to approximately 15% of its full light output, with a
corresponding decrease in input power.
Example Application of Step dimming using 0-10V Wires
Interfacing to an Occupancy Sensor:
The Dialight Low Bay fixture is ideally suited for control by an occupancy sensor in order to
maximize energy savings based on its instant-on behavior and low power consumption.
Instructions for connecting the High Bay fixture to an occupancy sensor are listed below.
WARNING: TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE
ELECTRICAL CODES AND REGULATIONS.
WARNING: CONTROLLING A LOAD IN EXCESS OF THE SPECIFIED RATINGS OF THE
OCCUPANCY SENSOR COULD DAMAGE THE UNIT AND POSE RISK OF FIRE, ELECTRIC
SHOCK, PERSONAL INJURY, OR DEATH. CHECK LOAD RATINGS TO DETERMINE THE
UNIT’S SUITABILITY FOR YOUR APPLICATION.
NOTE: SEE OCCUPANCY SENSOR INSTALLATION INSTRUCTIONS FOR ADDITIONAL
INFORMATION.
