Protective Trip & Warning Functions Chapter 3
• outputs will be placed in their Protection Fault state (if so programmed).
OVARC Inhibit Time, Parameter 253, allows the installer to inhibit an over
reactive power consumed trip from occurring during the motor starting sequence
and is adjustable from 0…250 seconds.
OVARC Trip Delay, Parameter 254, allows the installer to define the time period
an over reactive power consumed condition must be present before a trip occurs.
It is adjustable from 0.1…25.0 seconds.
OVARC Trip Level, Parameter 255, allows the installer to define the total
reactive power consumed in which the E3 Plus Overload Relay will trip. It is
adjustable from 0…32767.
Over Reactive Power Consumed Warning
The E3 Overload Relay will immediately indicate an over real power warning
condition if:
• no warning currently exists,
• Over Reactive Power Consumed Warning is enabled,
• OVARC Inhibit Time has expired, and
• Total Reactive Power is equal to or greater than the OVARC Warn Level.
When the over reactive power consumed warning conditions are satisfied, the:
• TRIP/WARN LED will flash an amber 2 long and 4 short blink pattern,
• bit 3 in PW Warn Status, Parameter 228, will set to “1”,
• bit 1 of Device Status, Parameter 21, will go set “1”
OVARC Warn Level, Parameter 256, allows the installer to define the total
reactive power consumed in which the E3 Plus Overload Relay will indicate a
warning and is adjustable from 0…32767.
Under Reactive Power Generated Trip
The E3 Overload Relay will trip with an under reactive power generated
indication if:
• no trip currently exists,
• Under Reactive Power Generated protection is enabled,
• UVARG Inhibit Time has expired, and
• Total Reactive Power is equal to or less than UVARG Trip Level for a time
period greater than the programmed UVARG Trip Delay.
When the under reactive power trip conditions are satisfied, the:
• TRIP/WARN LED will flash a red 2 long and 5 short blink pattern,
