Table 208 - L1 Over Current Trip Delay (Parameter 276)
L1 Over Current Trip Level
L1 Over Current Trip Level (Parameter 277) allows you to define the current at
which the E300 Electronic Overload Relay trips on a L1 Over Current. It is user-
adjustable from 10…100% of the FLA Setting (Parameter 171).
Table 209 - L1 Over Current Trip Level (Parameter 277)
L1 Over Current Warning
The E300 Electronic Overload Relay indicates an L1 Over Current warning if:
•
No warning currently exists
•
1 Over Current Warning is enabled
•
Current is present
•
The Over Current Inhibit Timer has expired
•
1 Percent FLA (Parameter 47) is greater than the L1 Over Current
Warning Level
When the L1 Over Current Warning conditions are satisfied, the:
•
TRIP/WARN LED flashes a yellow 11-short blink pattern
•
Bit 10 in Current Warning Status (Parameter 10) sets to 1
•
Bit 1 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Warning Alarm closes

IMPORTANT
The Over Current Inhibit Timer starts after the maximum phase of load current
transitions from 0 A to 30% of the minimum FLA setting of the device. The
E300 Electronic Overload Relay does not begin monitoring for an overcurrent
condition until the Over Current Inhibit Time expires.
