Protective Trip and Warning Functions
center enclosure is in a test position, and the E300 Electronic Overload Relay
detects motor current and/or voltage is present.
The E300 Electronic Overload Relay trips with a test mode trip indication if:
•
No trip currently exists.
•
Test Mode Trip protection is enabled.
•
The digital input that is assigned to read the Test Position feedback is
active. See Input Assignments (Parameters 196…201) in
.
•
Motor current and/or voltage is present.
If the E300 Electronic Overload Relay trips on a test mode trip, the following
occurs:
•
The TRIP/WARN LED flashes a red 3-long / 15-short blink pattern
•
Bit 14 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
•
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)
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)
IMPORTANT
Motor current is detected when a phase of load current transitions from 0 A to
30% of the minimum FLA setting of the device
