Protective Trip and Warning Functions
•
L2 Line Loss Warning is enabled
•
L2 Line Loss is activated via the appropriately programmed digital input
(see Input Assignments, Parameters 196…201, in
•
Line Loss Inhibit Timer has expired
•
L2 Percent FLA (Parameter 48) is equal to 0%
When the L2 Line Loss Warning conditions are satisfied, the:
•
TRIP/WARN LED flashes a yellow 15-short blink pattern
•
Bit 14 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
L3 Line Loss Trip
The E300 Electronic Overload Relay trips with a L3 Line Loss indication if:
•
No trip currently exists
•
L3 Over Current Trip is enabled
•
L3 Line Loss is activated via the appropriately programmed digital input
(see Input Assignments, Parameters 196…201, in
•
Line Loss Inhibit Timer has expired
•
L3 Percent FLA (Parameter 49) is equal to 0% for a time period greater
than the L3 Line Loss Trip Delay.
If the E300 Electronic Overload Relay trips on a L3 Line Loss, the:
•
TRIP/WARN LED status indicator flashes a red 16-short blink pattern
•
Bit 15 in Current Trip Status (Parameter 4) sets to 1
•
Bit 0 in Device Status 0 (Parameter 20) sets to 1
•
Any relay outputs configured as a Trip Relay open
•
Any relay outputs configured as a Control Relay open
•
Any relay outputs configured as a Trip Alarm close
•
Any relay outputs configured as a Normal Relay are placed in their
Protection Fault state (if so programmed)
IMPORTANT
The L2 Line Loss Warning function does not include a time delay feature. Once
the Line Loss Inhibit Timer has expired, the L2 Line Loss Warning indication is
instantaneous.
