Fault messages

10.1.1 General information about faults
Fault message display:
On the PMU: F (fault) and a three-digit number. The red LED (Fault) lights up.
On the OP1S: On bottom line of operational display: The red LED (Fault) lights up.
Only one current fault message can be displayed at a time, i.e. other simultaneously active faults are
ignored.
Many fault messages (see List of Fault Messages) can only be active in certain operating states.
The system responses to a fault are as follows:
•
The armature current is reduced, the firing pulses are disabled and the SIMOREG unit switches to
operating state o11.0 (fault)
•
Fault message is displayed on the operator panel (PMU, OP1S)
•
B0106 ( = status word 1, bit 3) is set and B0107 cancelled (see also alarm bits for special faults
such as undervoltage, overtemperature, external faults, etc.)
•
The following parameters are refreshed:
r047 fault diagnostic memory
(The displayed values are decimal. For bit-serial evaluation, the values must be
converted from decimal to binary notation, e.g. to be able to determine the
relevant terminal in the case of F018)
r049 Fault time
r947 fault memory, see also r947 in Section 11, Parameter List
r949 fault value
(The displayed values are decimal. For bit-serial evaluation, the values must be
converted from decimal to binary notation, e.g. to be able to determine the
relevant terminal in the case of F018)
P952 number of faults
A text is also displayed for each individual fault in parameter r951 (fault text list). These texts can, for
example, be displayed on the OP1S.
If a fault is not acknowledged before the electronics supply voltage is switched off, then fault message
F040 will be displayed when the supply is next switched on.
10.1.2 List of fault messages
NOTE
Further information about the causes of fault messages
When a fault message is activated, values providing more information about the fault cause are
stored in parameter r047. Where the values can be interpreted by the user, they are included in
the following list of fault messages.
The value in r047.001 is referred to as the "fault value". This is also stored in r949 which also
contains the fault values belonging to older fault messages. The values in r047 are overwritten
when the next fault message occurs.
Values for r047 which are not included in the list below can help a SIEMENS specialist to locate a
fault cause. For this reason, all indices of parameter r047 should be read out whenever a fault
message occurs, even if the meaning of the individual indices of parameter r047 is not specified
for every fault message listed below.
Please note: Before you contact SIEMENS with any query regarding a fault message, please
make a note of the contents of all indices of parameter r047.
