L3 Line Loss Trip Delay
L3 Line Loss Trip Delay (Parameter 288) allows you to define the time period an
L3 Line Loss condition must be present before a trip occurs. It is adjustable from
0.1…25.0 seconds.

L3 Line Loss Warning
The E300 Electronic Overload Relay indicates an L3 Line Loss warning if:
•
No warning currently exists
IMPORTANT
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and
Digital Module 4 Output Relays are defined by the respective parameters:
•
Output PT00 Protection Fault Action (Parameter 304)
•
Output PT00 Protection Fault Value (Parameter 305)
•
Output PT01 Protection Fault Action (Parameter 310)
•
Output PT01 Protection Fault Value (Parameter 311)
•
Output PT02 Protection Fault Action (Parameter 316)
•
Output PT02 Protection Fault Value (Parameter 317)
•
Output Digital Module 1 Protection Fault Action (Parameter 322)
•
Output Digital Module 1 Protection Fault Value (Parameter 323)
•
Output Digital Module 2 Protection Fault Action (Parameter 328)
•
Output Digital Module 2 Protection Fault Value (Parameter 329)
•
Output Digital Module 3 Protection Fault Action (Parameter 334)
•
Output Digital Module 3 Protection Fault Value (Parameter 335)
•
Output Digital Module 4 Protection Fault Action (Parameter 340)
•
Output Digital Module 4 Protection Fault Value (Parameter 342)

IMPORTANT
The Line Loss Inhibit Timer starts when L1, L2, or L3 Line Loss protection is
activated by a programmed digital input (see Input Assignment Parameters
196-201). The E300 Electronic Overload Relay does not begin monitoring for
Line Loss condition until the Line Loss Inhibit Timer expires.
