Protective Trip and Warning Functions
Over Frequency Trip
The E300 Electronic Overload Relay trips with an Over Frequency indication if:
•
No trip currently exists
•
Over Frequency Trip is enabled
•
Voltage is present
•
Over Frequency Inhibit Time has expired
•
The voltage frequency is greater than the Over Frequency Trip Level for a
time period greater than the Over Frequency Trip Delay.
If the E300 Electronic Overload Relay trips on an over frequency, the:
•
TRIP/WARN LED status indicator flashes a red 1-long / 6-short blink
pattern
•
Bit 5 in Voltage Trip Status (Parameter 5) 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)
Over Frequency Trip Delay
Over Frequency Trip Delay (Parameter 374) allows you to define the time period
an over frequency 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)
