The definition of a scheduled relay state change will require configuration of the following 8
values:
•
Type of day
Weekdays, defined as Monday through Friday
Weekends, defined as Saturday and Sunday
•
Special days or holidays
If the current day is designated as a holiday, the weekday and weekend schedules will be
ignored and the holiday schedule will be followed.
The holiday day definition is the same as that defined for the Time of Use (TOU)
functionality.
•
The state of the relay time
The start time is entered in hours and minutes with the minutes restricted to multiples of 15
minutes (for example, 0, 15, 30, 45).
There is no end time defined for the relay event. Instead, the event will end when the next
scheduled relay event for the same designated relay commences. Thus, all times for
schedules are defined in this single time value with the “end” time for an event being the
next event “start” time.
•
Desired state of the relay
The relay can be set to the open state or the closed state.
•
Whether the relay is to be connected or armed, when the schedule event is designated for
the main supply relay
•
The relay identifier
The relay identifier includes selection of the main supply relay (100 A for direct connect
variants and 2 A for the CT meter variant).
The relay identifier includes selection of the first load control relay (32 A for direct connect
variants and 2 A for the CT meter variant).
The relay identifier includes selection of the second load control relay (2 A for direct
connect variants).
•
Minimum randomization delay
The minimum randomization delay time is entered in hours (0
–
23) and minutes, with the
minutes restricted to multiples of 15 minutes (for example, 0, 15, 30, and 45).
•
Maximum randomization delay
The maximum randomisation delay time is entered in hours (0
–
23) and minutes, with the
minutes restricted to multiples of 15 minutes (for example, 0, 15, 30, and 45).
A value of zero (0) implies that randomization is not to be applied.
