Protective Trip and Warning Functions Chapter 5
Phase Rotation Trip
The E300 Electronic Overload Relay will trip with a Phase Rotation indication
if:
•
No trip currently exists
•
Phase Rotation Trip is enabled
•
Voltage is present
•
Phase Rotation Inhibit Time has expired
•
The measured Voltage Phase Rotation (Parameter 63) does not match the
•
required Phase Rotation Type (Parameter 364).
If the E300 Electronic Overload Relay trips on a phase rotation mismatch, the:
•
TRIP/WARN LED status indicator will flash a red 1-long / 4-short blink
pattern
•
Bit 3 in Voltage Trip Status (Parameter 5) 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)
Phase Rotation Trip Type
Phase Rotation Trip Type (Parameter 364) allows the installer to define the
required voltage phase rotation for the motor application. E300 Electronic
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:
