SIMOTRAS HD Operating Instructions
Fault Description
No. Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
Fault value: r047 Index 002 to 016:
1 Undervoltage has occurred
i002 Number of phase that has activated fault message
0 ... Phase UV
1 ... Phase VW
2 ... Phase WU
i003 Incorrect voltage value (normalized to 16384)
4 Undervoltage persists for longer than time set in
parameter P086 (if this is set to >0) -
F007 Overvoltage
(active in operating states of

Possible causes of fault
•
Line overvoltage
•
Monitoring values set too sensitively or incorrectly (P352, P078)
Fault value: r047 Index 002 to 016:
1 Overvoltage has occurred
i002 Number of phase that has activated fault message
0 ... Phase UV
1 ... Phase VW
2 ... Phase WU
i003 Incorrect voltage value (normalized to 16384)
4 Overvoltage persists for longer than time set in
parameter P086 (if this is >0) -
F008 Line frequency less than the minimum line frequency acc. to parameter P363
(active in operating states of ≤ o5)
This fault message is activated if the line frequency is less than the minimum line frequency
(for longer than the “restart time” set
in parameter P086).
Note: Up to software version 1.7 the threshold for activation of the fault message (minimum line frequency) is 45Hz.
Fault value:
1 Line frequency < minimum line frequency
4 Line frequency less than the minimum line frequency for longer than set in parameter P086 (if this is >0)
F009 Line frequency greater than the maximum line frequency acc. to parameter P364
(active in operating states of
≤
o5)
This fault message is activated if the line frequency is greater than the maximum line frequency (for longer than the “restart time”
set in parameter P086).
Note: Up to software version 1.7 the threshold for activation of the fault message (maximum line frequency) is 65Hz
Fault value:
1 Line frequency > maximum line frequency
4 Line frequency greater than the maximum line frequency for longer than set in parameter P086 (if >0)
10.1.2.2 Interface error
F011 Telegram failure at GSST1
when P780 = 2:
USS telegram failure at G-SST1
(active from the first receipt of a valid protocol in all operating states)
After the receipt of the first valid protocol, no further telegrams have been received within the time period set in parameter P787.
Possible causes of fault
•
Cable break
•
Error in USS master
