Protective Trip and Warning Functions Chapter 5
capability to put the overload relay into a Test Mode Trip state if motor control
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 will trip with a test mode trip indication if:
•
No trip currently exists.
•
Test Mode Trip protection is enabled.
•
The digital input assigned to read the Test Position feedback is active. See
Input Assignments (Parameters 196-201) in Chapter 3.
•
Motor current and/or voltage is present.
If the E300 Electronic Overload Relay trips on a test mode trip, the following will
occur:
•
The TRIP/WARN LED will flash a red 3-long / 15-short blink pattern
•
Bit 14 in Control Trip Status (Parameter 7) 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
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 device’s minimum FLA setting
