Wear Monitoring (13)
(Option, dependent on Type)
Only one proximity switch for wear monitoring (13) is required
per ROBA-stop
®
-stage brake, which is mounted onto the brake 1
(Fig. 5).
The ROBA-stop
®
-stage brakes are supplied with a manufacturer-
side installed and adjusted wear monitoring unit (13).

Function
Due to wear on the rotors (6.1 and 6.2), the air gap “a” between
the coil carrier (3) and the armature disk (4.2) increases
(air gap measurement is performed when brake circuit 1 is
energized), or the distance between the proximity switch (13.1)
and the adjusting screw (13.3) decreases.
Once the maximum air gap of 1.0 mm has been reached, the
proximity switch (13.1) contact switches over, the signal is
interrupted.
The brakes must be replaced. Factory overhaul is possible.
The customer is responsible for a signal evaluation.
Proximity Switch (13.1) Wiring Diagram
For technical data of the proximity switch
(13.1), please see
section “Release Monitoring
(9)
” on page 12.
Proximity switches cannot be guaranteed fail-
safe. Therefore, please ensure appropriate
access for replacement or adjustment.
If a replacement or new adjustment of the
proximity switch (13.1) is required by the
customer, separate adjustment instructions
stating the article or serial number of the
respective brake can be requested from the
manufacturer.
