NOTE ALSO!
If the supply to a subrack is switched on before the DSBC 174 or
DSBC 176 is in place, the process outputs in the subrack can set
themselves in optional states!
You should carefully follow general instructions and the information attached each board/unit
type in Section 5.5.10.1, Board and Subrack Mounted Unit Exchange.
The consequences to the process controlled must also be considered.
Proceed as follows:
1. Note the halt code on the processor module character display and the red LED indicators,
throughout the controller and its I/O, which illuminate
2. Perform a warm start that is an initialization with the start mode selector in position
1 (AUTO). If not successful continue at step 3.
3. Reduce the system until only the following modules remain
– 5 V Regulator SR511
– Processor Module PM511 including a program card
4. Perform a new warm start. If the system does not start continue at step 5. If the system
starts the fault is probably in the communication or the I/O system. Continue as follows:
a. Expand the system by returning modules to their original location.
b. First add Backup Power Supply SB510/511, System Status Collector TC520 and
remaining submodule carriers with communication interface modules, then the S100
I/O boards, one at a time, until the fault reappears.
c. Replace the module in which the fault appears.
d. Perform a warm start.
5. Perform a cold start i.e depress the ENTER button with the start mode selector in position
3 (CLEAR). Please note that the program card with the system program must be in its
position.
If the system does not start continue at step 6. If the system starts the fault is probably in
the data base or the PC program. Continue at step 7.
6. Replace the processor module and the submodule carrier with program card interface and
the program card, one at a time, until the controller starts in 3 (CLEAR) mode. Perform a
cold start after each replacement that is depress the ENTER button with the start mode
selector in position 3 (CLEAR).
7. Load in an available application program backup
8. Expand the system to full configuration.
