what is the self-learning matrix?
The self-learning matrix is a 7 day (7 x 24 hour), matrix with each 24 hour period divided into 48 30-minute periods. Each 30-
minute period has a state that ems controllers use to determine the mode as follows:
l
0 indicates no activity: ems controllers normally run in the
saving mode
.
l
1 indicates a change in activity: ems controllers run in the
ready mode
.
l
2 indicates activity: ems controller run in the
ready mode
.
For example, the self-learning matrix below shows the following:
l
Day 1 to day 3: the ems controller runs in the
ready mode
from 06:00 to 18:00.
l
Day 4 and day 5: the ems controller runs in the
ready mode
from 06:00 to 20:00.
l
Day 6: the ems controller runs in the
ready mode
from 08:00 to 14:00.
l
Day 7: the ems controller remains in the
saving mode
.
Note:
l
The self-learning matrix starts the moment the ems controller is first switched on and is not
synchronized with calendar days. However, the diagram below starts at 00:00 on Day 1 for clarity.

how a 7-day learning period works
ems controllers with a seven day learning period,
L P
set to 1, run in the
ready mode
for 7 days (7 x 24 hours), whilst the ems
controller learns the outlet activity pattern such as opening and closing times.
ems controllers start self-learning the moment the ems controllers are first powered-up.
At power-up, all the 30 minute periods are set to monitor (1) as shown in the following example matrix.
For periods set to monitor (1), ems controllers run in the
ready mode
.
