Maintenance / Inspection
ROBA
®
-servostop
®
brakes are mainly maintenance-free.
However, the friction linings of the rotor (4) are subject to
operational wear. The friction lining pairing is robust and
wear-resistant. This ensures a long service lifetime of the
brake.
If the rotor (4) does become worn due to the high total
friction work, and the function of the brake can no longer
be guaranteed, the brake must be replaced.
12
Wear
The wear condition of the rotor (4) is determined by
measuring the release voltage. The release voltage may
be up to max. 90 % of the overexcitation voltage on a
warm brake (= maximum temperature in case of applica-
tion).
The amount of wear on the rotor (4) must be examined
during the regular inspection intervals:
Wear times are influenced by many factors and can vary
substantially. The required inspection and maintenance
intervals must be calculated individually according to the
system manufacturer's planning documentation.
12.1 Cleaning:
Do not clean the brake using compressed
air, brushes or similar devices!
Wear safety gloves / safety goggles.
Use a suction system or wet towels to clean off the
brake dust.
Do not inhale brake dust.
In case of dust formation, a dust mask FFP 2 is rec-
ommended.
13
De-installation
WARNING Load crash possible
The brake must be load-free.
Please check that it is load-free before
de-installation.
Provide security in the danger zone.
Support the load
De-installation takes place by following the "Installation
Procedure" section 9.3 backwards.

Information on the Components
The
friction material
contains different inorganic and or-
ganic compounds, which are integrated into a system of
hardened binding agents and fibers.
Possible hazards:
No potential dangers have been recognized so far when
the brake is used according to its intended purpose.
When grinding in the brake linings (new condition) and
also in case of EMERGENCY STOP braking actions,
functional wear can occur (wear on the friction linings); on
open brake designs, fine dust can be emitted.
Classification: Hazardous property
Attention: H-classification: H372
Protective measures and rules of behavior:
Do not inhale dusts.
Vacuum the dusts at the point of origin (tested suction de-
vices, tested filters acc. DIN EN 60335-2-69 for dust clas-
ses H; maintenance of the suction devices and filter re-
placement at regular intervals).
If local dust suction is not possible or is insufficient, the
entire work area must be ventilated using appropriate
technology.
Additional information:
This friction lining (asbestos free) is not a dangerous
product in terms of the EU Directive.
