In the following malfunction responses of monitoring equipment are clearly listed.
Depending on the type of malfunction discovered, an annunciation is sent, a restart of
the processor system is initiated, or the device is taken out of service. After three un-
successful restart attempts, the device is taken out of service. The live status contact
operates to indicate the device is malfunctioning. In addition, if the internal auxiliary
supply is present, the red LED "ERROR" lights up on the front cover and the green
"RUN" LED goes out. If the internal power supply fails, then all LEDs are dark. Table
2-11 shows a summary of the monitoring functions and the malfunction responses of
the relay.
