2.22.1.4 Malfunction Responses
Depending on the type of malfunction detected, an indication is sent, a restart of the
processor system initiated, or the device is taken out of service. After three unsuccess-
ful restart attempts, the device is also taken out of service. The operational readiness
NC contact („life contact“) operates to indicate the device is malfunctioning. The red
„ERROR“ LED on the device front lights up, provided that there is an internal auxiliary
voltage, and the green „RUN“ LED goes off. If the internal auxiliary voltage fails, then
all LEDs are dark. Table 2-16 shows a summary of the monitoring functions and the
malfunction responses of the relay.
