Table 113 - Line Loss Inhibit Time (Parameter 285)
L1 Line Loss Trip
The E300 Electronic Overload Relay will trip with a L1 Line Loss indication if:
•
No trip currently exists
•
L1 Over Current Trip is enabled
•
L1 Line Loss is activated via the appropriately programmed digital input
(see Input Assignments, Parameters 196-201, in Chapter 3)
•
Line Loss Inhibit Timer has expired
•
L1 Percent FLA (Parameter 47) is
•
equal to 0% for a time period greater than the L1 Line Loss Trip Delay.
If the E300 Electronic Overload Relay trips on a L1 Line Loss, the:
•
TRIP/WARN LED status indicator will flash a red 14-short blink pattern
•
Bit 13 in Current Trip Status (Parameter 4) will set to 1
•
Bit 0 in Device Status 0 (Parameter 20) will set to 1
•
Any relay outputs configured as a Trip Relay will open
•
Any relay outputs configured as a Control Relay will open
•
Any relay outputs configured as a Trip Alarm will close
•
Any relay outputs configured as a Normal Relay will be placed in their
Protection Fault state (if so programmed)
