Important Notes
•
The low voltage Dimming wires are connected to the grounded output section of the driver inside the
light. Never connect either one to the Hot or Neutral supply wires.
• The ‘-‘ wire (Black) is at ground potential.
• Never use these wires for any purpose other than dimming.
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 High 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
