pressing the ON/OFF/DIM button for another 10 seconds).
During the TEST mode, the controlled load turns ON for 5 seconds each
time the sensor that initiated the TEST mode detects occupancy.
2. Move out of the coverage area or stand very still. The controlled load turns
OFF after 5 seconds if no motion is detected.
3. Move into the coverage area for the unit that initiated the TEST mode.
The controlled load turns ON for 5 seconds each time the sensor detects
motion. After 5 seconds expire without motion detection, the load turns
OFF. The controlled load turns ON automatically with the next motion
detection and stays ON for 5 seconds.
4. Repeat as necessary to ensure that the desired coverage areas are within
detection range.
You can do this test for each RD‑250 in your multi‑way configuration. So
that you can determine the actual coverage area for each multi‑way switch
individually, only the RD‑250 that is in TEST mode will control the load.
REPLACING LAMPS
When replacing a lamp connected to a RD‑250, use the Air Gap Isolation
feature for safety. If you have more than one RD‑250 controlling one or
various loads in a multi‑way wiring configuration, apply the instructions
below to all RD‑250s for safety.
1. Push in the Air Gap Switch shown in Figure 5 so that it clicks and locks
into a depressed position below the surface of the rest of the RD‑250. This
engages the Air Gap, which stops electricity from flowing to the connected
load.
2. After replacing the lamp(s), press the Air Gap Switch so that it returns to a
position that is flush with the surface of the rest of the RD‑250. This allows
the dimming sensor to control the lighting load correctly.
3. The RD‑250 then calibrates its dimming range to the load's wattage
rating by briefly dimming the load up and down from its minimum output
(approx. 10%) to its maximum.
TROUBLESHOOTING
Check the position of the Air Gap Switch on all RD‑250s before beginning
troubleshooting.
Lighted switch is OFF, no load response to ON/OFF/DIM button(s) press or
to any of the RH‑253 momentary wall switches (if applicable):
• Make certain that the circuit breaker is on and functioning.
Lighted switch is ON, no load response to ON/OFF/DIM button(s) press or
to any of the RH‑253 momentary wall switches (if applicable):
• Check the controlled dimmable lighting load(s). Make sure that the load(s)
connected to the RD‑250s is (are) between 25‑ 500 watts.
• The lighting load (s) may not appear to be ON if the last used dimming
level was very low. To verify if this is the case, firmly tap the ON/OFF/DIM
button one time. The amber LED should turn off. Next, press and hold the
ON/OFF/DIM button to turn UP the lighting level. If the lights do not get
brighter, call technical support.
Load will not turn ON automatically when the area is occupied and the
sensors are in Mode 2 (lighted switch is ON):
• Press ON/OFF/DIM button(s). If the load turns ON, check the Light Level
setting. The light level can prevent the sensor from turning ON the load
automatically. Make sure the sensor lenses are not blocked and that you
are within the coverage area of at least one sensor.
• If the load does not turn ON when you press the ON/OFF/DIM button(s),
check the dimmable lighting load(s). Make sure that the load connected to
the RD‑250(s) is between 25‑ 500 watts.
• The lighting load may not appear to be ON if the last used dimming level
was very low. To verify if this is the case, firmly tap any ON/OFF/DIM button
one time. The amber LED should turn off. Next, press and hold the same
ON/OFF/DIM button to turn UP the lighting level. If the lights do not get
brighter, call technical support.
• If the load(s) does (do) not turn ON when you press the ON/OFF/DIM
button, check the light bulb.
Load will not turn OFF automatically:
• Press the ON/OFF/DIM button. If the controlled load turns OFF, go to next
step.
