Setpoint learning
Your meter can learn acceptable ranges or thresholds by monitoring normal operating values to
determine what constitutes a voltage sag, or swell to help identify high and low setpoints.
NOTE: To help your meter learn the most accurate values possible, it is important that learning
occur during a period of normal operation. Do not schedule learning during a period of unusual
operations in your system. Do not modify your meter's configuration during the learning period
as it may stop the learning process.
You can configure the meter so that learned values are applied automatically after the learning
period is complete or require that they are reviewed and manually applied. If a learned value is
invalid, the learned values are not automatically applied, but logged for review.
Setpoint learning can be used to identify the following values:
Feature
Setpoints (Alarms)
Sag
Swell
Learning installation mode and learning duration
You can configure learning for manual or automatic mode.
There are two learning installation modes:
1. Manual: The meter learns the applicable values but does not begin using the learned
values. The learned values are recorded for review, and you can decide to use the learned
values or adjust them as required before manually implementing the learned values.
2. Automatic: The meter learns the applicable values and begins using those learned values
automatically at the end of the learning period. If a learned value is invalid, the meter does
not apply the value, but the value is recorded in the event log.
You can configure the maximum learning duration. The actual learning duration may vary,
depending on the stability of the system. If the system is stable for a period equal to one quarter of
the maximum learning duration, learning is complete; otherwise, the learning period will be the
maximum learning duration.
Example: Setpoint learning duration in a stable system
In this example, the learning duration is 30 days. When the system is stable for 7.5 days (one
quarter of 30 days) learning is complete.
