Carrying out commissioning
1. Start a test run at low swivel speed.
2. When conducting the test run, check whether the DRRD settings need to be corrected.
These could be:
–
swivel angle of the payload (
Tab. 3)
–
swivel speed of the payload.
3. Unscrew the one-way flow control valves (A) slowly again up to the desired swivel speed.
4. Interrupt the test run if the piston can be heard to strike hard.
Causes of metallic knocking may be:
–
mass moment of inertia of the payload too high
–
swivel speed of the payload too high
–
no compressed air cushion on the exhaust side
–
shock absorber unscrewed too far (maximum values
Tab. 4).
5. Make sure you remedy the above-mentioned causes.
6. End the test run when all of the necessary corrections have been undertaken.
