Over Voltage Warning
The E300 Electronic Overload Relay indicates an Over Voltage warning if:
• No warning currently exists
• Over Voltage Warning is enabled
• Voltage is present
• Over Voltage Inhibit Time has expired
• The maximum phase voltage is equal to or greater than the Over Voltage
War n in g L e v el
When the Over Voltage Warning conditions are satisfied, the:
• TRIP/WARN LED flashes a yellow 1-long / 2-short blink pattern
• Bit 1 in Voltage Warning Status (Parameter 11) sets to 1
• Bit 1 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Warning Alarm closes
Over Voltage Warn Level
Over Voltage Warn Level (Parameter 362) allows you to define the voltage at
which the E300 Electronic Overload Relay indicates a warning. It is user-
adjustable from 0…6553.5 volts.

Default Value 500.0
Minimum Value 0.0
Maximum Value 6553.5
Parameter Type UINT
Size (Bytes) 2
Scaling Factor 10
Units Volts
The Over Voltage Inhibit Time starts after a phase voltage transitions from 0V
to 20V L-L. The E300 Electronic Overload Relay does not begin monitoring for
an over voltage condition until the Over Voltage Inhibit Time expires.
Default Value 490.0
