Protective Trip and Warning Functions Chapter 5
• 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 will flash a yellow 3-short blink
pattern
• Bit 2 in Current Warning Status (Parameter 10) will set to 1
• Bit 1 of Device Status 0 (Parameter 20) will set to 1
• Any relay outputs configured as a Warning Alarm will close
Ground Fault Warning Level
Ground Fault Warning Level (Parameter 246) allows the user to define the
ground fault current at which the E300 Electronic Overload Relay will indicate a
warning and is adjustable from 0.20…5.00 A.
Table 77 - Ground Fault Warning Level (Parameter 246)
Ground Fault Warning Delay
Ground Fault Warning Delay (Parameter 245) allows the user 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.
