Protective Trip and Warning Functions Chapter 5
If the E300 Electronic Overload Relay trips on an under power factor lagging,
the:
• TRIP/WARN LED status indicator will flash a red 2-long / 9-short blink
pattern
• Bit 8 in Power Trip Status (Parameter 6) 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)
Under Power Factor Lagging Trip Delay
Under Power Factor Lagging Trip Delay (Parameter 411) allows the installer to
define the time period an under power factor lagging condition must be present
before a trip occurs. It is adjustable from 0.1…25.0 seconds.

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)
