Protective Trip and Warning Functions
•
Over Current Inhibit Timer has expired
•
L1 Percent FLA (Parameter 47) is greater than the L1 Over Current Trip
Level for a time period greater than the L1 Over Current Trip Delay.
If the E300 Electronic Overload Relay trips on a L1 Over Current, the:
•
TRIP/WARN LED status indicator flashes a red 11-short blink pattern
•
Bit 10 in Current Trip Status (Parameter 4) 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)
L1 Over Current Trip Delay
L1 Over Current Trip Delay (Parameter 276) allows you to define the time
period an L1 Over Current 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)
