ALARM Output
The ALARM output contact signals an alarm
condition by going to its deenergized state.
•
The ALARM output b-contact closes for an
alarm condition; the ALARM output a-contact
opens for an alarm condition or if the relay is
deenergized.
•
The relay generates a STATUS report at the
serial port for failures.
•
The relay displays failure messages on the
relay VFD display.
Use the serial port STATUS command or
front-panel Status of Relay function to view the
relay self-test status.
