Chapter 5 Programmable Parameters
E3 is Tripped
In the event of a protection trip, the state of an E3 Overload Relay output is
determined by the programmed settings of the corresponding Out_ Pr FltState
and Out_ Pr FltValue parameters.
When Out_ Pr FltState is set to “Ignore Fault”, output operation continues to
respond to message commands. When Out_ Pr FltState is set to “Go to FltValue”,
the output commanded states are determined by the settings of the Out_ Pr
FltValue parameters, regardless of the state of the firmware latch.
Series A product continues to update the firmware latch as new commands are
received while the E3 Overload Relay is in a tripped state.
Series B and later product sets the firmware latch to the Out_ Pr FltValue when
Out_ Pr FltState is set to “Go to FltValue” while the E3 Overload Relay is in a
tripped state.
E3 is Reset from Trip
After an E3 Overload Relay is returned to normal following a trip reset, operation
of Out A and Out B is determined by the state of the firmware latch. The output
state matrix below details this.
