118 Rockwell Automation Publication 193-UM015B-EN-P - June 2014
Chapter 5 Protective Trip and Warning Functions
Current is present
Over Current Inhibit Timer has expired
L1 Percent FLA (Parameter 47) is greater than the L1 Over Current Trip
Le
vel 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 will flash a red 11-short blink pattern
Bit 10 in Current Trip Status (Parameter 4) 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
P
r
otection Fault state (if so programmed)
L1 Over Current Trip Delay
L1 Over Current Trip Delay (Parameter 276) allows the installer to define the
time period a 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)
