time to wait before alarming if the above conditions
are not satisfied.
•
Llev Pr Delay
- Light level proofing alarm delay.
The Light Level Proof Delay is the amount of time
after sunrise or sunset that, if the light level sensor
does not cut ON or OFF appropriate to the light
level of a sunrise or sunset, generates an alarm. In
other words, if the Light Level Proof Delay is set
for 1 hour, the light level must fall below the cut-off
setpoint at least one hour after sundown, or an
alarm is generated. Likewise, if the cut-on Light
Level setpoint is not reached by at least one hour
after sunrise, an alarm is generated.
•
Dim Upper %
- Upper dimmer percentage.
•
Dim LL @ Upper%
- Light level at upper dimmer
percentage.
•
Dim Lower %
- Lower dimmer percentage.
•
Dim LL @ Lower%
- Light level at lower dimmer
percentage.
•
Dim Ramp Speed
- Ramp speed in percent per
minute.
•
Dim Fail %
- Percentage when light level sensor
fails.
•
Dim Shed %
- Percentage when a demand shed
event is present.
5.4.8 External Schedule
An input is provided to allow a time schedule
application to be connected to the Lighting Application.
5.4.9 Lighting Bypass Inputs
The application provides two bypass inputs:
•
Bypass ON
- When ON, this input will force the
digital lighting output ON.
•
Bypass OFF
- When ON, this input will force the
digital lighting output OFF.
5.4.10 Demand Shed Behavior
The application provides a demand shed input. When
this input is ON, the Lighting Application turns the
lighting output OFF. Generally, this input is connected to
the Demand Control application.
If the lighting application is configured to use
dimming, the lighting output is set to the “Dim Shed %”
value while a shed event is active.
5.5 Global Data
The Global Data application is the central location for
commonly used data values and limited data calculations
such as degree days and seasonal determination.
The following are the global data outputs:
•
SUMMER WINTER
- Summer/Winter indication
output.
•
COOLING DEGREE DAY
- Indicates the current
cooling degree day calculation based on the
“integration” method. The calculation starts over at
midnight for the new day and the previous day's
calculation is logged.
•
HEATING DEGREE DAY
- Indicates the current
heating degree day calculation based on the
“integration” method. The calculation starts over at
midnight for the new day and the previous day's
calculation is logged.
•
ENTHALPHY DEGREE DAY
- Indicates the
current enthalpy day calculation based on the
“integration” method. The calculation starts over at
midnight for the new day and the previous day's
calculation is logged.
•
DAY SCHED OUT
- Indicates current day of week
or holiday.
5.5.1 Location From
Sunrise and sunset times are calculated based on either
zip code or latitude/longitude. If
US Zip Code
is chosen in
the
Unit Location From
field, enter the zip code in which
the controller is located. If outside the United States,
choose
Lat/Long
and enter the latitude and longitude
values in which the controller is located. Once a value has
been chosen, the controller is able to calculate the sunrise
and sunset times. The Sunset output will turn ON at
sunset, and OFF at sunrise and can be connected to a
lighting circuit.
5.5.2 Sundown
Sundown is an output that calculates when the sun sets
based on latitude and longitude, and is ON when the sun
sets. (When a Lighting Schedule is configured to use
Sundown information, the Lighting Schedule application
automatically connects to the Sundown output).
