LEGRAND Wattstopper FSP-211B Instrucciones De Instalación página 4

IR communication can be affected by the mounting height of the sensor
and high ambient lighting such as direct daylight or electric light such as
floodlights, and some halogen, fluorescent lamps, LED's.
When trying to communicate with the FSP-211B, be sure to be positioned
under the sensor without any obstructions. Every time the commissionng
tool establishes communication with the FSP-211B, the controlled load
will cycle.
Lights will not go to High Mode:
• Check all wire connections and verify the load and the ground wires are tightly secured.
• Make sure that the sensor is not obstructed.
• Check light level parameter, to find out the amount of light that the sensor is detecting. Cover the sensor lens to simulate darkness
in the room. If the lights come ON, the setpoint needs to be adjusted. If set for minimum, more than 1 fc at the sensor of ambient
light will cause the lights to be held OFF. See the new settings section for instructions.
• If lights still do not turn ON, call 800.879.8585 for technical support.
Lights will not go into Low Mode:
• The time delay can be set from a minimum of 30 seconds to a maximum of 30 minutes. Ensure that the time delay is set to the
desired delay and that there is no movement within the sensor's view for that time period.
• To quickly test the unit operation, enable test mode and move out of the sensor's view. Lights should fade to low mode after 5
seconds.
• If lights still do not fade to Low Mode, call 800.879.8585 for technical support
Lights will not turn OFF:
• Cut Off time may be set to "Disable."
• Ensure that the Cut Off is set to the desired time and that there is no movement within the sensor's view for that time period when
the lights are in Low Mode.
• To quickly test the unit operation, enable test mode and move out of the sensor's view. Lights should fade to low mode after 5
seconds and then turn OFF (if cut off is enabled) after 10 sec.
• If lights still do not turn OFF, call 800.879.8585 for technical support.
False Triggering may occur if the sensor is exposed to high ambient temperature conditions and the unit is set to maximum sensitivity
for PIR detection.
• If this occurs, reduce the PIR sensitivity setting from maximum to a medium point and re-check unit operation.
• If experiencing false triggering during fade down/Off, try increasing the fade time.
Lights do not turn ON:
Check for blinking red LED. If the LED blinks twice, the sensor has reached its Hold Off setpoint, if the LED blinks 3 times, the sensor
has reached its Photocell Light Level setpoint.
Lights suddenly turn off and will not come back on:
Check for blinking red LED. If the LED blinks twice, the sensor has reached its Hold Off setpoint, if the LED blinks 3 times, the sensor
has reached its Photocell Light Level setpoint.
There is no IR communication:
Perform a power cycle on the FSP-211B.
The first time the sensor is installed and powered, there will be 50 seconds of warm-up. The load will turn OFF after the warm up time if
no motion is detected.
