Protective Trip and Warning Functions
Table 231 - Over Voltage Trip Level (Parameter 361)
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
Warning Level
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.

IMPORTANT
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.
