3. Intended use
The brake has been designed for use as a holding, control and stopping brake.
Use for any other purpose will be deemed improper.
4. Impermissible use
The brake must not be operated with a voltage higher than the value specified in the technical
data or with other media. In addition, unauthorized structural changes to the brake are not
permitted. RINGSPANN shall not be liable for any damage resulting from this; the user alone
bears the risk of such damage.
5. Condition as delivered
When delivered, the brake has a clamping gap of approx. 8.0 mm between the friction blocks.
When the electromagnet is actuated, the brake opens to the preset clamping gap of 13.1 mm =
brake disc thickness 12.5 mm and an air gap of 0.3 mm on both sides between the brake disc
and the friction blocks.
6. Handling and storage
The brake weighs between 7 kg and 10 kg, depending on the version.
The brake is delivered preserved and can be stored in a closed, dry place for 12 months. Make
sure that no condensation occurs. Humid storage rooms are unsuitable. If the brake is stored for
a longer period than 12 months, as well as after each transport, the brake must be applied once
to prevent the seals and wipers from sticking together.
7. Technical requirements for save operation
Fastening the brake to stable and low-vibration machine parts will ensure quiet braking without
squeak.
8. Installing the RINGSPANN brake
8.1 General instructions regarding assembly and installation
Before installing the brake, the brake disc must be cleaned with alcohol (e.g. spirit (ethanol) or
isopropyl alcohol) or with water-based tenside solutions (soapy water or the like).
If cleaning the brake disc with a diluent, acetone or brake cleaning agent, it must be ensured that
these agents and no residues of these agents come into direct contact with the friction blocks.
This must be ensured for pure holding brakes in particular, since no dynamic braking takes place
that would remove any diluent residues from the brake disc.
Important!
Residues from oil and anti-rust agent considerably reduce the coefficient of friction
and thus also the braking and holding torque!
