Window blinds:
If installed in the area, adjust them to maximize daylight while not allowing direct beam sunlight to enter the controlled
area. At night, adjust them so they block lighting from outdoor fixtures.
Lights from other areas:
If non-dimmed lights in adjoining areas contribute to the light viewed by the FD-301, these lights must be on
during both Day and Night adjustments.
Target Illuminance Levels
Determine the illuminance required in the controlled space. In some applications, a footcandle target may be specified for the controlled
space. If this is the case, use a light meter to take measurements before and during the commissioning process. Choose a reference
location in the controlled area that is most likely to have the lowest illuminance level when daylit, and is located farthest from the window
or skylight. If the illuminance level is too low, select another location, or measure the illuminance level on a brighter day. If no target
illuminance is specified, adjustments can be based on user perception or preferences.
Adjustment Procedure
Initial adjustments to the FD-301 are done using the LSR-301-S remote control. The LSR-301-S has 5 buttons. The
LED on the remote control should light every time you press a button. The FD-301’s green LED also flickers for the
duration of the press.
p
(up arrow) Press to increase light output.
q
(down arrow) Press to decrease light output.
Night:
Press to begin and end the Night adjustment process.
Auto:
Press to begin automatic dimming.
Day:
Press to begin and end the Day adjustment process.
Day Adjustment
Make this adjustment when daylight is providing illumination that is typical of the daytime conditions at the reference
location in the controlled area.
1. Press the
Day
button once. The FD-301’s green LED flickers.
2. Press
p
or
q
to adjust the electric lights to the appropriate light level.
If an illuminance target is specified by the lighting designer, use a light meter at the workplane to verify the
footcandle value.
3. Once the appropriate illuminance level is reached, press and HOLD the
Day
button for 3 seconds. The FD-301
acknowledges setting of the Day target setpoint by lighting the green LED twice for 3 seconds each time.
Night Adjustment
Make this adjustment when there is no daylight illumination at the reference location. To complete the night commissioning during the
day, the night environment must be simulated by blocking all sources of daylight.
1. Press the
Night
button once. The FD-301’s green LED flickers.
2. Press
p
or
q
to adjust light level.
If an illuminance target is specified by the lighting designer, use a light meter at the workplane to verify the footcandle value.
3. Once the target level has been reached, press and HOLD the
Night
button for 3 seconds. The FD-301 acknowledges setting of
the Night target setpoint by lighting the green LED twice for 3 seconds each time.
Begin Automatic Dimming
To immediately begin automatic dimming after the Night and Day adjustments are BOTH completed, press the
Auto
button. Otherwise,
ten minutes after the last adjustment keypress (Step 3):
• If only Night is done, the signal to the ballast remains at the level to which it was adjusted and the red LED continues to flash.
• If only Day is done, the signal to the ballast goes to full output (10VDC) and the red LED continues to flash.
• If Night and Day are done, the FD-301 begins automatic dimming.
USER DIMMING CONTROL
Using the LSR-301-P, the user can raise the target illuminance level by up to 25% of the target illuminance level set
with the LSR-301-S during commissioning, or reduce it to the lamp/ballast minimum. Pressing the
p
(up arrow) or
q
(down arrow) temporarily raises or lowers the target illuminance level. The FD-301 controls the lights to maintain the
new target level until another button is pressed.
Pressing
Auto
cancels the user adjusted target illuminance level. The FD-301 returns to automatic dimming using the
levels set with the LSR-301-S.
