Time Delays - LEGRAND Wattstopper PW-311 Mode D'emploi

Auto ON
With DIP switch 1 in the OFF position, the load turns ON and OFF automatically based on occupancy. There is a 5 second re-trigger
delay. If the load is turned OFF manually, the enable/disable setting for Presentation Mode operation applies. See Presentation Mode /
Disable Presentation Mode for details.

Time Delays

The PW sensor holds the load ON until no motion is detected for the selected time delay. Select the time delay using DIP switches 2
and 3. Available time delays are 3, 5, 15, and 30 minutes.
When you set both DIP switches to the OFF position, the PW-311 enters Test Mode, and the delay is set to a short time delay of only 10
seconds. After 10 minutes, Test Mode cancels and the delay reverts to 3 minutes. Or, if you select a different value for either of the two
time delay DIP switches, Test Mode cancels immediately and the delay is set to the time specified by the DIP switch values. Moving both
switches back to OFF re-triggers Test Mode. See DIP SWITCH SETTINGS for specific setting values.
DIP Switches 6 through 9 provide access to a number of additional features. Each feature is selected by choosing a unique combination
of the DIP switches. Once you select the specific values, the red LED will blink, indicating you are in Setup Mode. While in Setup Mode,
the green LED blinks distinctively—once, twice, three times, or four times—to indicate the current value for that feature.
To change the current setting of the selected feature, press and release the UP or DOWN buttons. The current value for the feature will
advance to the next available higher or lower value. For example, if the green LED is blinking once, if you press and release UP once,
it will blink twice. If you press and release UP again, it will blink three times. Press and release the DOWN button to select a lower blink
value.
NOTE: For the High and Low Trim features, press and hold the UP or DOWN buttons till the light is at the desired trim level. The
Light Level Adjustment feature has its own specific method for changing the value. See that section for details.
Once programming is complete, return all four DIP switches to the OFF value. The PW-311 exits Setup Mode, saves the current values
for each feature, and resumes normal operation. The saved values are remembered in the event of a power loss.
NOTE: After 10 minutes, the PW-311 will exit Setup Mode even if the four DIP switches are not returned to the OFF value. This prevents
the PW-311 from being left in Setup Mode unintentionally. In this case, any changes will not be saved and the unit will revert to
its previous settings.
Following is a description of the additional programmable features. See the DIP SWITCH SETTINGS section, for a table showing the
switch combinations for each feature, as well as the specific values indicated by the blinking green LED.
Alerts
The PW can provide audible and/or visible alerts as a warning before the load turns OFF. By default, visible alert is disabled and audio
alert is enabled.
Walk-Through
The Walk-Through mode shortens the time delay to reduce the amount of time the load is ON after a brief moment of occupancy, such
as returning to an office to pick up a forgotten item then immediately exiting. If Walk-Through Mode is turned ON, the PW sensor turns
the load OFF three minutes after the area is initially occupied, if no motion is detected after the first 30 seconds. If motion continues
beyond the first 30 seconds, the set time delay applies. Walk-Through Mode is OFF by default.
PIR Sensitivity Adjustment
The PW sensor constantly monitors the controlled environment and automatically adjusts the PIR to avoid common ambient conditions
that can cause false detections, while providing maximum coverage. You can also manually select a sensitivity value. The default is
High, which is suitable for most applications. A value of Low reduces sensitivity by approximately 50%. This is useful in cases where
the PIR is detecting movement outside of the desired area (you may also be able to address this by masking the lens) and where heat
sources cause unnecessary activation.
High and Low Trim
You can adjust the maximum and minimum dimming amounts by adjusting the High and Low Trim (each trim value is adjusted
separately). By default, the values are set at 100% (10V) for High Trim and OFF (0V) for Low Trim. If set to Manual Adjustment, press
the Up or Down buttons to set the parameters to the desired level.
Ramp Up and Fade Down Time
You can adjust the amount of time it takes to Ramp Up from the Low Trim value to the High Trim value when motion is detected, or Fade
Down from High Trim to Low Trim after no motion is detected and the time delay has expired. The available values for ramp up are 1
(default),2½, 5, and 10 seconds. Available values for fade down are 2½ (default), 5, 15, and 30 seconds.
NOTE: The ramp up time will be scaled if the Preset On Level is anything less than the High Trim amount. For example, if the Low Trim
is set to 0V and High Trim is set to 10V (the defaults) and the Ramp Up Time is set to 10 seconds, that is one volt per second. If
the Preset On Level is set to Last Non-Zero Value and the on value was previously at 6V, then it will take 6 seconds to ramp up,
since is it one volt per second.
NOTE: These parameters do not affect the time to ramp up or fade down when pressing the Up or Down buttons to raise or lower the
light level. Instead, this is always set to 2 volts per second. So going from 0–10 volts when pressing the Up button will always
take 5 seconds.
