Maintenance
10.5 Corrective maintenance
For operational braking, the maintenance intervals depend on the loading on the brake in
the application. Take all causes of wear into account when calculating the maintenance
intervals. Siemens recommends a regular inspection at fixed time intervals for brakes that are
subject to low loads, e.g. holding brakes with an emergency stop.
Failure to maintain the brake can lead to operating faults, production outage or damage
to the plant. Specify a maintenance plan for each application that is appropriate to the
operating conditions and loading of the brake. The maintenance intervals and maintenance
work for the pneumatic brake are listed in the table.
