DESCRIPTION
Learned motor thermal capacity used since last
start. See 3.21: THERMAL CAPACITY ALARM on
page 3–59 for details on using this value to adapt
the relay to the motor.
Learned motor thermal capacity used on start. This
value is learned after 5 successful starts. The start
thermal capacity for each of the last five starts are
added together and divided by 4. This allows a
margin of 24% to be built into the value. Each start is
limited between 10% and 70% of the thermal
capacity used on start.
This learned parameter is used with the start inhibit
function on Setpoints page 5. See Section 3.21:
THERMAL CAPACITY ALARM for details.

figures on pages 2–31 to 2–37 for details.
This message is displayed when the meter's VTs are
wired to measure for phase to phase voltage.
