Fault Handling; Minute Pulse - Siemens SIMEAS R-PMU Manual

Fault Handling

Evaluate the log recorder (chapter 13) and the device status (chapter 12.1) for fault analysis in
the event of synchronization faults.
During fault handling, a distinction is always made between non-critical and critical
synchronization faults. A non-critical fault is logged, but does not trigger the message
„synchronization malfunction". A critical fault is logged and simultaneously triggers the message
„synchronization malfunction".
After the synchronization has failed (LED 13 is OFF or flashing), the SIMEAS R-PMU waits for
a valid synchronization signal. As soon as LED 13 starts flashing, a valid synchronization signal
has been detected. If LED 13 is permanently lits, the measuring system has locked to the
synchronization signal and the device is synchronized.
Note
Synchronization adjustment of the measuring system can take up to 45 minutes!
