Astro
Enabling Astro Lights On commands the lights ON at
sunset (± the On Offset Time). Enabling Astro Lights Off
commands the lights
OFF at sunrise (± the On Offset
Time). (Note that for the sunset and sunrise times to be
correct, the longitude, latitude, Daylight Savings Time,
and UTC offset must be correct for the location of the
controller.)
Photocell Input
Allows the user to reference a binary (BI, BV, MI, MV) or
analog (AI, AV) input reference. The Lights On and
Lights Off checkboxes set the Schedule to trigger the LG
On Only, Off Only, On & Off, or neither Off nor On. If an
analog object is set as the Photocell Input, then the
“Lights On when equal/below” and/or “Lighting Off
when equal/above” threshold values must be entered to
define at what point LG should be command
ON or OFF .
Scheduling
Calendar (CAL) and Schedule (SCH) objects are used for
scheduling date and time events. Calendar objects allow
selection of days of the year. The Calendar object
transitions from
OFF to ON when the controller date
matches the date selected in the Calendar object.
Calendar (CAL) objects can be referenced to Schedule
(SCH) objects. Calendar objects are listed in Table 9.
Up to eight ON / OFF intervals per day for each day of the
week and two Calendar references can be entered into
Schedule (SCH) objects. When day-of-the-week and
entered
ON time equal that of the controllers, the
Schedule object transitions from O F F to ON . When a
Calendar is referenced to a Schedule object and the
Calendar is
ON, the Schedule will only execute the
Calendar ON / OFF times. Schedule objects are listed in
Table 10.
Events/Data Logging
The Compact Event Log (CEL) can record up to 2000
database events. The Binary Output (BO) Event Enable
checkboxes allow customization of which breaker events
can be generated. Viewing the kogged events and event
enable customization are functions available with the LCD
Programmer. The CEL records the following events:
• Command failure
• Breaker tripped
• Breaker
ON/OFF
• Reset device
• Device online or offline
• Undervoltage
• Load/save
Event log objects are listed in Table 11.

* Date format is year/month/day/week of day. If the current date matches an entry in
the Calendar’s date list, then the Calendar’s value is ON. A calendar object can
accommodate 90 dates and a 10-year span.

* A schedule consists of eight sets of time entries (Day 1 = Monday, 7 = Sunday, 8 = Calendar). Each
set of time entries consists of eight ON/OFF time pairs (1 st entry is an OFF time, 2 nd entry an ON
time, 3 rd entry an OFF time, and so on). The first entry is usually 00:00 to indicate an OFF time, in
case the previous day ended with an ON time up to midnight. If a day has fewer than eight pairs,
the empty pairs are filled with 0xFFFF. Only Function Code 06 can remove an entry (by writing
0xFFFF).

* The Compact Event Log stores system events. It uses a FIFO circular buffer of 2000 events. Event count
contains the number of events in the Log. Each event record is a block of eight registers.
