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.

Activity
EMS controllers learn when retail outlets are open or closed by monitoring activity. For example,
people opening and closing the cooler door to retrieve products or movements detected in front of
the cooler. EMS controllers detect activity as follows:
l
Door switch to detect door openings as customers open the cooler door to retrieve products.
l
Motion sensor to detect movement in the front of the cooler.
Note:
l
EMS controllers must be able to detect activity to work correctly. The motion detector should never be obstruc-
ted.
The diagram below shows the detection pattern of the motion sensor.
