CHAPTER 5: SETTINGS<br />
Note<br />
5.5.3 Force Output <strong>Relay</strong><br />
For example, serious trips such as Short Circuit and Ground Fault may be assigned to the<br />
2 AUXILIARY relay so that they can only be reset via the remote reset terminals (D18 and<br />
D23) or the communication port. The remote reset terminals should be connected to a<br />
keyswitch so that only authorized personnel could reset such a critical trip.<br />
• Assign only Short Circuit and Ground Fault to the 2 AUXILIARY relay<br />
• Program 2 AUXILIARY to “Remote Reset Only”<br />

The output relays can be independently forced in static or dynamic mode. In static mode<br />
the selected relay will operate as long as it is in the “Enabled” state. Only when the user<br />
enters “Disabled” will the selected relay reset. In dynamic mode the user specifies the<br />
operate time (1 to 300 seconds) and the selected relay will operate for the specified<br />
duration.<br />
The FORCE OUTPUT RELAY option is NOT allowed when the selected relay output is already<br />
active due to trip or alarm condition, when the <strong>469</strong> is in start block condition, or when the<br />
<strong>469</strong> is not in service.<br />
IMPORTANT NOTE: The forced relay will override any trip or alarm conditions. (i.e. when the<br />
relay is forced and trip occurs, the relay will still be enabled when the trip condition is reset).<br />
Control power loss in the <strong>469</strong> will reset all forced relays.<br />
