TROUBLESHOOTING
The red LED will flash until both the Day and Night levels are properly adjusted. The Night level must always require more electric light
output than the Day level. If it does not, the red LED on the FD-301 flashes to indicate an invalid setpoint.
ON/OFF SWITCHING
To turn
OFF
fixtures, a manually operated switch, time clock, BAS, or occupancy sensor can be installed in conjunction with the
FD-301 and FS-PP. This instruction describes operation with an FS-series occupancy sensor and one option for using a switch. Contact
technical support for help with other switching applications.
Operation with an Occupancy Sensor
When an occupancy sensor is installed in the FD-301 system, the fixture turns
OFF
if no motion is detected in the area for the length
of time set in the sensor’s time delay, regardless of the light level. When the occupancy sensor detects motion in the area, the fixture
initially turns
ON
to full output, then the FD-301 reads the illuminance level and begins automatic dimming to maintain the target
illuminance level.
Operation with a Switch
When a switch is used to turn
OFF
power to the fixture and the FD-301 is wired as shown in Figure 6, the fixture and FD-301 system
turn
OFF
when the switch opens. When the switch is again closed, the fixture initially turns
ON
to full output, then the FD-301 reads the
illuminance level and begins automatic dimming to maintain the target illuminance level.
INSTALLATION IN THE FIXTURE
Mount the FD-301 so the fixture’s lamp output (candlepower curve profile) is outside the sensor’s peak sensitivity area.
1. Install the FS-PP as directed in the installation instructions provided with the power pack.
2. Determine an appropriate mounting location for the FD-301 inside the light fixture. Cut a 3/4” diameter hole through the sheet
metal in the bottom of the fixture.
A beauty ring and thumbscrew collar are supplied to secure the FD-301 lens through the fixture wall. Depending on the wall
thickness and curvature, you may need to use the thumbscrew collar on the inside or outside of the fixture, or not at all, as shown
in Figure 3.
3. Remove the beauty ring and thumbscrew collar from the FD-301 lens pipe.
4. Insert the lens from the inside of the fixture, through the hole in the bottom of the fixture.
• If the lens extends too far outside the fixture, use the thumbscrew collar to adjust the depth.
• Tighten it to the outside of the fixture or tighten it against the sensor body before inserting the lens through the fixture wall.
• Then put the beauty ring onto the lens pipe and tighten it securely.
WIRING
For daylight dimming control (see Figure 4):
1. Plug in the RJ-45 from the FD-301 into the TO SENSOR receptacle on the FS-PP.
2. Connect the violet and grey wires from the FD-301 to the 0-10V inputs on the dimming ballast.
To also provide
ON/OFF
control using an occupancy sensor, see Figure 5, or to provide manual
OFF
control using a local switch, see
Figure 6. For other control options, contact technical support.
Configuring the Optional Occupancy Sensor
Use the instructions supplied with the FS-series sensor to install the sensor in the fixture, connect the sensor to the FS-PP and to set the
time delay. Some FS-series occupancy sensors are equipped with a light level sensor. Be sure to set the light level on the occupancy
sensor to maximum, meaning that even the brightest ambient light will not hold the lights off.
