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. 4.8.2 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 operational braking, the maintenance intervals depend on the load on the brake in the specific application. Take all causes of wear into account when calculating the maintenance intervals. Siemens AG recommends a regular inspection at fixed time intervals for brakes that are subject to low loads, e.g. holding brakes with an emergency stop.
Ensuring functional safety 4.8 Service and maintenance Failure to maintain the brake can lead to operating faults, production outage or damage to the plant or system. Specify a maintenance concept for each application that is appropriate for the operating conditions and the brake load. The maintenance intervals and maintenance work for the L brake are listed in the table.
