9. Commissioning
Only full-face contact of the two friction blocks (2) on the brake disc as well as a rapid heating of
the friction linings to approx. 200°C will ensure an optimal braking effect. It is therefore necessary
to brake several times and for a short duration when the brake disc is rotating. This process is
finished when the friction surface shows a contact pattern of at least 70 to 80%.
Important!
If the brakes are used as holding brakes, then the braking torques indicated in the
catalogue will not be reached. Reductions of up to 50% of the braking torque are
possible.
10. Disassembling the brake
Life-threatening danger!
When disassembling the brake it is to be ensured that the entire drive train is
secured against being switched on unintentionally. Rotating parts can cause
severe injury. Rotating parts (e.g. brake disc) must be secured by the operator
against unintentional touching.
Important!
Make sure that no electrical voltage is applied to the brake caliper.
Remove the rubber cap (9) and screw on the hexagon nut (8) until an air gap between brake pad
and brake disc is adjusted and the brake disc can be turned freely.
Remove the two screws M12 - 8.8 which serve to fix the brake. The brake caliper can now be
removed from the mounting surfaces.
11. Maintenance
11.1 General maintenance
The brake caliper must be serviced at intervals of 4 to 12 weeks, depending on the application.
The following points must be checked during maintenance:
•
Check the friction blocks for wear.
•
Check that the friction blocks do not rub against the brake disc when the brake caliper is
released, or that there is an even air gap of approx. 0.4 mm on both sides.
•
Check the screw connection of the brake caliper to the machine part and the screw
connection of the friction blocks for tight screw connection.
•
Check the screw connection and the tight fit of the inductive proximity switch (optional).
•
Check the screw connection of the electromagnet to the brake caliper lever.
•
Check both brake caliper levers for easy moving.
•
Clean the bearing and sliding points.
•
Check the electrical wiring and connections.
