Dynamic Reset
Dynamically tracks the thermal capacity
needed for a successful restart after an
overload trip. It averages the thermal
capacity consumed in the previous three
successful starts and calculates a
thermal capacity to Start.
On: If there is insufficient capacity to
start the unit it will be “inhibited” from
starting.
Off: If there is insufficient capacity to
start the unit it will not be “inhibited” from
starting
