Time Clocks
There are three
Time Clocks in the system are used as conditionals in programs. They are used solely to define time periods
during the week when certain programs should be enabled or disabled to execute.
TIME CLOCK 1 ON
TIME CLOCK 1 OFF
Specify the on and off times for each
Time Clock - See Set Up Codes.
TIME CLOCK 1 ON TIME:
12:00 AM MTWTFSS #=CHNG
TIME CLOCK 1 OFF TIME
-- NEVER #=CHNG
For example, it may be desirable to have certain programs to execute only during a normal Monday - Friday 9:00 AM - 5:00 PM
work week. The default for
Time Clock 1 ON is 12:00 AM MTWTFSS, and the default for Time Clock 1 OFF is Never, so that
Time Clock 1 is always Enabled.
TIME CLOCK 2 ON
TIME CLOCK 2 OFF
TIME CLOCK 3 ON
TIME CLOCK 3 OFF
Time Clocks 2 and 3 is entered into the system and set for time and dates exactly like the settings for Time Clock 1 .
Latitude, Longitude, and Time Zone
The system automatically calculates the time of sunrise and sunset each day. Sunrise/sunset can be specified as the time a
scheduling command is executed, as an enable/disable time, or as a darkness condition on a scheduling command or event button.
To enable the system to properly calculate sunrise and sunset times, you must enter your latitude, location north or south of the
equator, longitude, location east or west of the Prime Meridian, and time zone.
These items should be set to the proper values for the location where the Lumina is installed. The latitude and longitude for a
particular location may be obtained from an almanac or map of the area. These values should be entered to the nearest degree.
The value entered for the time zone is the number of hours difference between local standard time at the Lumina location and
Greenwich Mean Time. The following values should be used for the standard time zones in North America:
ZONE NAME
4 ATLANTIC
5 EASTERN
6 CENTRAL
7 MOUNTAIN
8 PACIFIC
9 YUKON
10 ALASKA-HAWAII
11 BERING
The value specified for longitude may be adjusted to correct for areas, such as Nova Scotia, where the local time differs from
Greenwich Mean Time by a non-hourly amount. The calculated time of sunrise/sunset will change by four minutes for every
degree change in longitude. To cause the calculated sunrise/sunset to occur later, enter a larger value for longitude. Enter a
smaller value for longitude to cause the time to occur earlier.
