TEST OUTPUT RELAYS

[ENTER] for more
The test output relays setpoint may be used during startup or testing to verify that the output relays are functioning cor-
rectly. The output relays can be forced to operate only if the generator is offline, no current is measured, and there are no
trips or alarms active. If any relay is forced to operate, the relay will toggle from its normal state when there are no trips or
alarms to its operated state. The appropriate relay indicator will illuminate at that time. Selecting "Disabled" places the out-
put relays back in service. If the 489 measures current or control power is cycled, the force operation of relays setpoint will
automatically become disabled and the output relays will revert back to their normal states.
If any relay is forced, the 489 In Service indicator will flash, indicating that the 489 is not in protection mode.

These setpoints may be used during startup or testing to verify that the analog outputs are functioning correctly. The analog
outputs can be forced only if the generator is offline, no current is measured, and there are no trips or alarms active. When

4 to 20 mA or 0 to 1 mA. Selecting "Disabled" places all four analog output channels back in service, reflecting their pro-
grammed parameters. If the 489 measures current or control power is cycled, the force analog output function is automati-
cally disabled and all analog outputs will revert back to their normal state.
Any time the analog outputs are forced, the In Service indicator will flash, indicating that the 489 is not in protection mode.
