Output Pt02 Assignment (Parameter 204)
Output Pt02 Assignment (Parameter 204) allows the user to assign this relay
output for the following functions:
Table 47 - Output Pt02 Assignment (Parameter 204)
Activate FLA2 with Output Relay (Parameter 209)
Activate FLA2 with Output Relay (Parameter 209) allows a user to activate the
value in FLA2 Setting (Parameter 177) for the current based protection
algorithms when the assigned output relay is in an energized state.

Expansion Bus Fault The E300 Electronic Overload Relay’s expansion bus can be used to expand the
I/O capabilities of the E300 Electronic Overload Relay with the addition of
digital and analog expansion I/O modules. The Expansion Bus Fault allows a user
to have the E300 Electronic Overload Relay go into a Trip or Warning state when
established Expansion Bus communications is disrupted between the Control
Module and any digital and analog expansion I/O modules.
The Expansion Bus Fault is used when the Option Match feature is not enabled
for the digital and/or analog expansion I/O modules. The Expansion Bus Fault
only monitors for communication disruptions between the Control Module and
digital and/or analog expansion I/O modules. Expansion bus communication
disruptions between the Control Module and Operator Station do not affect the
Expansion Bus fault.
Value Assignment Description
0 Normal Function as a relay output
1 Trip Relay
Function as a normally closed contact until the E300 is in a tripped state in which the relay
opens. The Trip Relay remains open until a trip reset is issued.
2 Control Relay
Function as a combination Normal and Trip Relay. The Control Relay is in a normally open
state until the relay is commanded to close by communications or via a DeviceLogix
program. When the E300 enters into a tripped state the Control Relay opens and remains
open until a trip reset is issued.
3 Trip Alarm
Function as a normally open contact until the E300 is in a tripped state in which the relay
closes. The Trip Alarm remains closed until a trip reset is issued.
4 Warning Alarm
Function as a normally open contact until the E300 is in a protection warning state in which
the relay closes. The Warning Alarm remains closed until the protection warning clears.
