4.4 Evaluation Computer Fault Types
4.4.2 Emergency Shutdown
S
SAFETY REQUIREMENTThe following times must be observed after an emergency shutdown:
After an emergency shutdown corrective maintenance (evaluation computer disconnected) must be carried out within 8 days!
If the evaluation computer is disconnected after an emergency shutdown for a longer time, the permissible out-of-service period is 5.5 months (only if supply voltage is switched off immediately after channel failure).
If these times are exceeded, special safety measures must be performed. The evaluation computer may only be put into operation again by Siemens specialist staff.

Figure 17 Front view of STEU board, display for emergency shutdown (TVDS 1 to 4) The EC has failed completely. An emergency shutdown results in all track vacancy detection sections being indicated as occupied. The cause of the fault
An emergency shutdown is indicated by LED 0 flashing on both STEU boards.
The faults that have caused the emergency shutdown can be identified using the following tables:

Description of fault codes
Fault code Description/cause Remedy
02 Serious system fault; interrupt INT 3 triggered –
0C During system start, the two channels of the reset buttons
(AzGrT or AzGrH) are not synchronous • Check if the buttons are connected correctly or if one of the buttons does not work properly (contact problems)
0E Stack overflow –
10 SOPP run not terminated in due time –
1C Time-out (time-out period of 70 ms) –
20 Checksum error during memory test (LED 5 on) –
