6.1.5 Special cases for tightening results
Special cases sometimes occur, the results of which do not originate from the last performed step. These
cases are divided into the two variants described below.
6.1.5.1 Special cases with results output from the previous step
Here, the results (actual and set values) are not from the last performed step, but from the preceding step.
This takes place if, for example, the tightening has been ended in a step that does not deliver any "real"
tightening results, e. g. abort in a synchronization step.
In these special cases, if the results from the last completed step were output and stored, the torque/
angle of turn information from the tightening would be lost.
1 A+, T+, G+ mean that the upper limit for the angle, torque, or gradient has been exceeded.
A–, T–, G– mean that the lower limit for the angle, torque, or gradient has not been reached.
The entries in the table correspond to the condition upon delivery. The table can be changed in the BS350
operating system and transferred to CS, KE, or SE.

Example Sequence with sync step
An abort in the sync step (4A) produces the following result:
• Step number: 4A
• Quality code: QC 132, synchronization (sync), from step 4A
• Stopped by: SB 19
• Rework code for QC 132, depending on the configuration of the
quality code table
• Evaluation: OK/NOK from step 4A
• Tightening results from step 3A
• Tightening category from step 4A (always 0, as it is not configurable)
If a docu buffer is configured in step 3A, the tightening results are output
in both docu step 3A as well as result step 4A
The printer output, for example, would appear as follows (here, the data
from step 3A are shown in red and the data from step 4A in green):
