Protective Trip and Warning Functions Chapter 6
• 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)
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 4
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 trips 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
occurs:
• The TRIP/WARN LED flashes a red 3-long / 5-short blink pattern
• Bit 4 in Control Trip Status (Parameter 7) sets to 1
• Bit 0 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Trip Relay open
