DNCKE/KEC
7 Operation
Before releasing the clamping:
WARNING
Unexpected movement of components.
Injury due to impact or pinching.
• Make sure that there is a balance of forces acting on the operating cylinder's piston.
There is a danger of the piston rod advancing suddenly when it is loosened due to
axial force (weight force) applied, especially with vertical installation.
Observe the following after each adjustment:
Note
• Check clamping unit for safe function after each adjustment
(è 6.4 Clamping force test):
If the clamping unit does not clamp the payload securely:
• Readjust the clamping unit (è 6.2 Adjustment of the clamping unit).
If there are changes in the payload or operating pressure:
Note
Payloads that have been increased at a later time and a changed operating pressure
change the clamping conditions and might impair operational reliability.
• Observe permissible maximum load limits (è 13 Technical data).
If the clamping unit does not clamp the payload securely:
• Readjust the clamping unit (è 6.2 Adjustment of the clamping unit).
In case of dynamic braking due to unavoidable irregular movement:
Note
Use of the product as a braking device does not conform with the intended use. De­
pendent on the braking load, dynamic braking can jeopardize the future operational
reliability of the clamping unit. Check clamping unit for safe function
(è 6.4 Clamping force test).
Note
A permanently pressurised clamping unit can jeopardize the operational reliability.
• Exhaust the clamping unit at least once per day.
