Malfunction Responses
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 unsuccessful restart attempts, the device is taken out
of service. The operational readiness NC contact operates to indicate the device is malfunctioning. Also, the
red LED ”ERROR" lights up on the front cover, if the internal auxiliary voltage is present, and the green ”RUN"
LED goes out. If the internal auxiliary voltage fails, all LEDs are dark. Table 2-14 provides a summary of the
monitoring functions and the malfunction responses of the relay.
