Fault information
Behavior in the event of a
fault
If a fault is triggered in a synchronization station which
leads to an output stage inhibit, the entire synchroniza-
tion network will immediately switch to the status "Output
stage inhibit". The fault will then be displayed on the af-
fected station until it is reset.
Reset
You can find information about resetting a fault in the
MOVITRANS® TES31A Decentralized Supply Unit docu-
mentation in chapter "8.3 Fault reset". The master for-
wards a reset via edge change to all the slaves. Other re-
set types must be performed on the respective station.
When resetting a station, refer to the information in
chapter For your safety.
Behavior
Cause
A slave does not receive any readiness
message at input DI01, although the up-
stream station sends this report (output
DO01).
Check that the cabling on the units at in-
terfaces X5102_1 and X5102_2 is correct
and check for possible cable breakage.
A slave has the status "Not ready" al-
though all the conditions are fulfilled.
The slave has not yet received a valid
synchronization signal. Check the syn-
chronization cable for:
•
Correct installation at interface X5122
•
Cable breakage
•
Terminating resistors
