Timer Functions & Learned Values
The lower right quadrant of the metering tab has two pages – Timer Functions and
Learned Values. You can toggle between these two displays by clicking on the button
located in the bottom right corner of the metering tab display.
Timer Functions: this section displays the current values of several internal timers
within the device. Most of these functions must be programmed in the relay in order
to function. Refer to the device manual for specific usage details.
Learned Values: this section displays items tracked by the relay. For full details on
their usage, consult the relay manual.
Backspin features – these are only enabled when the Backspin option is installed in
the relay.
Learned cool time constants – these are enabled only if the "Enable Learned Cool
Times" feature is programmed.
Learned k factor is only enabled by setting the unbalance biasing of thermal capacity
to on/learned.
Clearing Motor Data (see control tab) will set all these values to their defaults.
