3.1.5 Manual release (optional)
To temporarily release the brake when there is no electricity available, a manual release function is available
as an option (instead of the transport safety bolts otherwise used). The manual release system works on both
brake circuits together.
3.1.6 Optional cover ring
This design reduces the penetration of spray water and dust. It also prevents the spread of abrasive particles
outside the brake. This is achieved by a cover seal over the armature plate and rotor.
3.1.7 Noise reduction (optional)
In addition to the standard noise reduction, the armature plates can be fitted with noise reducers. This will
reduce the switching noises.
3.1.8 Project planning notes
❚ The brakes are dimensioned in such a way that the given rated torques are reached safely after a short
run-in process.
❚ However, as the organic friction linings used do not all have identical properties and because environ-
mental conditions can vary, deviations from the specified braking torques are possible. These must be
taken into account in the form of appropriate dimensioning tolerances. Increased breakaway torque is
common in particular after long downtimes in humid environments where temperatures vary.
❚
Check the braking torque if the brake is inserted on the customer's friction surfaces.
❚ If the brake is used as a pure holding brake without dynamic load, the friction lining must be reactivated
regularly.
NOTICE
❚ The manual release is designed for activation via a Bowden cable.
❚ Releasing an individual brake circuit is only possible electrically.
NOTICE
It is possible to retrofit the manual release system, 29.
