initial delay. For example, if time is set to 20 minutes, the load will go from ON to the Low Trim level 20 minutes after occupancy is no
longer detected. The the load will then turn OFF 10 minutes after it goes to the Low Trim level.
Fade Time – For all modes except Mode E and Test Mode, the fade up time from OFF to ON or OFF to High Dim Level is 2 seconds,
and the fade down time from ON to Low Dim Level or Low Dim Level to OFF is 10 seconds. For Mode E and Test Mode, fade up and
fade down time is 0 seconds.
Mode A – High/Low/Off Dimming for Indoor Parking Structure or High-Bay
Features: Transition between High, Low, and Off levels; Adjustable Hold Off Setpoint; High trim and low dim levels are
variable
This mode has a hold off light level set point, which can be adjusted to the desired light level
using Set trimpot, or disabled (when the Set trimpot is turned to the minimum setting).
Anytime occupancy is detected with ambient light level below the hold off set point, the load
turns ON (ramping up to the High trim level).
NOTE: In this mode, since there is no daylighting control, the High Trim level will be the
maximum amount of light for the load. (The High Trim level is set in Mode E.)
Once no occupancy is detected and the time delay expires, the load will fade down to the
Low Dim level which is 10% of High Trim level. As long as the area remains unoccupied, the
load stays at the Low Dim level for half the amount of the time delay, and then load turns
OFF.
When the hold off light level set point is enabled using the Set trimpot, once the Load turns
OFF, after 5 seconds if the ambient light level is more than the set point value, the load will
stay OFF even if occupancy is detected. But if occupancy is detected within the 5 seconds,
the load will return to the High Trim value, even if the ambient light level is more than the hold off level.
NOTE: When you select mode A, The HBP-212 will initially enter Test mode and stay in test mode for 5 minutes, after which it will switch
to mode A operation. (Test Mode is identical mode to A, with the exception of Time Delay, which is fixed at 5 seconds.)
Mode B – Continuous Dimming Control with Daylighting (Dim to Off )
Features: Adjustable photocell level to set desired light level when
occupied
When the ambient lighting is below the desired light level and occupancy
is detected, the sensor turns the loads ON. The dimming level continually
adjusts so that the dimming amount combined with ambient light matches
the desired light level. If the ambient lighting is above the desired light level
when occupancy is detected, the load will remain OFF until the ambient light
drops below the target level, at which point it will adjust the dimming level
appropriately.
Once no occupancy is detected and the time delay expires, the load fades
down to the Low Dim level, which is 50% of the High Trim level. As long as
the area remains unoccupied, the load stays at the Low Dim level for half the
amount of the time delay, and then load turns OFF. If the current dimming level
is less than half of the High Trim value, the load fades down to OFF without any
time delay.
NOTE: With the photocell enabled in this mode (as well as in modes C and
D), the High Trim is used only to calculate the Low Dim amount. It
can therefore be set to an amount lower than the maximum dimming
amount, which is set based on the desired light level. For example: if
the High Trim level is set to 8V, in Mode B the Low Dim level will be 4V.
But if the desired light level is set high, the lights might go up to 9V or
10V in order to reach the desired level.
NOTE: If the photocell is disabled in this mode (as well as in modes C and D),
the High Trim amount will be used to determine the desired light level,
as it does in Mode A.
Mode C – Continuous Dimming Control with Daylighting (Dim to
Low Level)
Features: Adjustable photocell level to set desired light level; a minimum
light level is always maintained.
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. If the ambient
lighting is above the target photocell level, the dimming level will adjust to the
Low Dim level (20% of High Trim value).
Once the area is unoccupied and the time delay expires, the load level will fade
down to the Low Dim level (20% of High Trim value). The load will never turn
completely OFF.
