DSMI−...−B
Note
If the impact is too hard, it will cause the stop lever to rebound out of the end
position, resulting in a reduction of the service life.
If the stop lever can be heard to strike hard:
7. Interrupt the test run.
Causes of hard knocking may be:
Mass moment of inertia of the moving mass too high
Swivel speed of the moving mass too high
No compressed air cushion on the exhaust side
Insufficient shock absorption.
8. Make sure you remedy the above−mentioned causes.
9. Repeat the test run.
When all necessary corrections have been made:
10. End the test run.
Fine adjustment of the end positions
Note
An adjustment sleeve that is screwed out too far 5 or a shock absorber that is
screwed in or out too far results in the stop lever:
Either hitting the adjustment sleeve or the shock absorber at an
impermissible angle or
Hitting the shock absorber retainer without shock absorption.
In such a case there is a risk of the DSMI or the shock absorber being
destroyed.
· Make sure that you do not screw the adjustment sleeve or shock absorber in
or out any further than shown in the following table (è Fig. 26).
· Pressurise the desired end position on the DSMI.
The end positions can be adjusted under pressure.
