Table 211 - Percent Thermal Capacity Utilization (Parameter 1)
Time to Trip
When the measured motor current exceeds the trip rating of the E300 Electronic
Overload Relay, Overload Time to Trip (Parameter 2) indicates the estimated
time remaining before an overload trip occurs. When the measured current is
below the trip rating, the Overload Time to Trip value is reported as 9,999
seconds.
Table 212 - Overload Time to Trip (Parameter 2)
Time To Reset
After an overload trip, the E300 Electronic Overload Relay will report the time
remaining until the device can be reset through Overload Time to Reset
(Parameter 3). When the % Thermal Capacity Utilized value falls to or below the
Overload Reset Level (Parameter 174), the Overload Time to Reset value will
indicate zero until the overload trip is reset. After an overload trip is reset, the
Overload Time to Reset value is reported as 0 seconds.
