The compression plate shall now slow down and stop, when the preset
compression force is reached.
Decompression button
5
Check the decompression button on the separate control console for proper function,
i.e. that the compression plate moves upwards when the button is pressed.
Checking the OPCOMP
5
1. Decompress.
2. Set the compression force to 20 kg by using the presetting knob (5/Fig. 10) and
compress.
The compression movement must be interrupted by OPCOMP before
20 kg is
reached, i.e. at 5-15 kg depending on the material (4/Fig. 10) used.
Adapting OPCOMP
If the factory-set OPCOMP is not to the customer’s satisfaction, an adjustment can be car-
ried out with the tautness factors in the
Optimized compression dr table, see Service
Instructions ( Software, SPB7-250.816.02... ). A lower tautness value will increase the
compression force and vice versa.
•
Increase/decrease the tautness factor by e.g. 10 the first time. Let the customer use this
setting for at least two weeks before further changes are made.
During compression, the motorized vertical adjustment and the
rotary motion of the swivel arm system shall be blocked.
OPCOMP has been thoroughly tested by Siemens. If any factors
are changed, OPCOMP will no longer be an optimization of com-
pression force and image quality according to Siemens’ clinical
test.
