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.
