Mode D – Continuous Dimming Control with Daylighting (Separate Low Dim Levels when there is No Occupancy)
Features: Adjustable photocell level to set desired light level; a minimum light level is always maintained, with separate day time
and night time minimum levels
During the day time, when occupancy is detected and if the ambient lighting
is below the desired light level, the dimming level continually adjusts so that
the dimming amount combined with ambient light matches the desired light
level. Once the dimming level reaches 40% of the high trim level, the sensor
will consider it to be night time and will behave as described in the following
paragraph. If the ambient lighting is above the target photocell level, the
dimming level will adjust to the Day Time Low Dim level (20% of High Trim value).
Additionally, when there is no occupancy and the time delay expires, the load level
will fade down to the Day Time Low Dim level.
During the night time, when occupancy is detected, the dimming level adjusts to
the desired light level. When there is no occupancy and the time delay expires, the
load level will fade down to the Night Time Low Dim level (40% of High Trim value)
in order to maintain a safe light level. Once the dimming level is less than 40% of
the high trim operation, the sensor switches back to day time operation.
In this mode, the load will never turn completely OFF.
NOTE: If the photocell is disabled, then the day time/night time behavior does
not apply. In this case, after the time delay expires the lights will dim to
40% of the High Trim level, and then after an additional 1/2 of the time
delay amount, the lights will dim further to 20% of high dim level.
Mode E – Service/Setup Mode
Features: Allows visual adjustment of High Trim level
If the Time trimpot is set at maximum, the load turns ON at the current High Trim amount.
Adjust the Set trimpot to the desired amount. This amount will be the maximum amount of
light in Mode A and will set the High Trim amount for Modes, B, C, and D. If the Time trimpot
is set at minimum, the load turns OFF.
Note that after turning the Time trimpot to change the ON/OFF setting, the unit will not
respond to further changes for 3 seconds.
Test Mode
Test mode sets the time delay to 5 seconds to allow for testing the occupancy sensor.
Whenever Mode A is selected using the Mode trimpot, the HBP-212 will enter Test mode for 5 minutes. If the HBP-212 is currently in
mode A, selecting another mode and then returning to mode A will restart Test mode. During Test mode, daylight control is not active
and the value of the Time trimpot is overridden. When occupancy is detected the load will turn ON at the High Trim value. Once no
occupancy is detected, the load will got to the Low Dim level after 5 seconds, and then will stay at that level for 2.5 seconds, before
turning OFF. After 5 minutes, the unit will revert to normal Mode A operation.
