Chapter 5 Protective Trip and Warning Functions
• 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)
Remote Trip
The E300 Electronic Overload Relay provides the capability to remotely cause
the E300 Electronic Overload Relay to trip via a network command or assigned
digital input on the Control Module (see
Chapter 3 for digital input
assignments). This feature allows the capability of tripping the E300 Electronic
Overload Relay from a remote source such as a vibration switch or external
monitoring relay.
The E300 Electronic Overload Relay will trip with a remote trip indication if:
• No trip currently exists
• Remote Trip is enabled
• A Control Module’s digital input with a remote trip assignment is
activated or the Communication Module receives a remote trip command
from the communications network
If the E300 Electronic Overload Relay trips on a remote trip, the following will
occur:
• The TRIP/WARN LED will flash a red 3-long / 5-short blink pattern
• Bit 4 in Control Trip Status (Parameter 7) 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
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)
