Protective Trip and Warning Functions
Chapter 6
•
Ground Fault Current is equal to or greater than the Ground Fault
Warning Level for a time period greater than the Ground Fault Warning
Delay.
When the ground fault warning conditions are satisfied, the:
•
TRIP/WARN LED status indicator flashes a yellow 3-short blink pattern
•
Bit 2 in Current Warning Status (Parameter 10) sets to 1
•
Bit 1 of Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Warning Alarm close
Ground Fault Warning Level
Ground Fault Warning Level (Parameter 246) allows you to define the ground
fault current at which the E300 Electronic Overload Relay indicates a warning
and is adjustable from 0.20…5.00 A.
Table 181 - Ground Fault Warning Level (Parameter 246)
Ground Fault Warning Delay
Ground Fault Warning Delay (Parameter 245) allows you to define the time
period (adjustable from 0.0…25.0 s) for which a ground fault condition must be
present before a warning occurs.
