Siemens SIPROTEC 5 User Manual

Supervision of the Device Hardware
Overview
The correct state of the device hardware is a requirement for the correct functioning of the device. The failure
or erroneous function of a hardware component leads to device malfunctions.
The following modules of the device hardware are monitored:
•
Base module
•
Expansion modules
•
Plug-in modules on the interface locations
•
SDHC memory card
The fault responses result, depending on type and degree of the error, as follows:
Hardware errors where the device remains in operation.
The error is indicated. The signals/data affected by the failure are marked as invalid. In this way, the affected
protection functions can switch into a secure state. Such errors are, for example:
•
Communication-module failure (module x)
•
Measuring-transducer module failure (module x)
•
USB interface
•
Integrated Ethernet interface
•
Real-time clock building block
•
A/D converter (fast current sum)
•
Battery voltage
•
Faulty or missing compensation values (magnitude/phase)
•
SDHC memory card (see also A.9 Troubleshooting SDHC Memory Card )
Failures which can partially be corrected by a restart of the device. The device goes briefly out of opera-
tion.
Such errors are, for example:
•
Memory error (RAM) in the base module
•
Faulty module
•
Module-connection error (PCB Link)
•
Control circuit error binary output
•
Outage of an internal auxiliary voltage

NOTE
If the error has not be rectified after 3 unsuccessful attempts, the system automatically recognizes it as a
severe device malfunction. The device goes permanently out of operation into a secure state (fallback
mode).
Fatal device errors with outage of central components: The device goes permanently out of operation
into a secure state (fallback mode).
Such errors are, for example:
•
Memory error (flash) in the base module
•
CPU/Controller/FPGA error in the base module
•
3 unsuccessful restarts in a row
