Responsibility and liability regarding functional safety
The responsibility and liability regarding the functional safety and its associated traceability is
completely transferred to the operating company:
• If the operating company damages the seal that was attached by Siemens AG.
• If the operating company carries out work in the area around the seal.
• If the operating company performs work on the rotary encoder or the brake and the

It is not permissible that the system is still operated if the maximum air gap s
The braking torque is significantly reduced if the maximum air gap is exceeded.
NOTICE
Improper maintenance
Only authorized qualified personnel may perform the maintenance and servicing. Only original
parts supplied by Siemens AG may be installed.
NOTICE
Working on the brake
Only Siemens service personnel or personnel trained and authorized by Siemens may carry out
the work on the brake.

Wear of spring-operated brakes
The friction lining and the mechanical components of the brake are subject to wear due to their
inherent function. For safe and fault-free operation, the brake must be regularly checked and
adjusted, and if necessary, replaced.
The following table describes the different causes of wear and their effects on the spring-
operated brake components. The important influencing factors have to be quantified in
order to calculate the service life of the rotor and the brake and determine the stipulated
maintenance intervals. Here, the most important factors are the work as a result of the
frictional force, the speed at the start of braking and the frequency of operation. If several of
