Fig.18: Brake pad wear measurement
In the example, the device is installed at the end of a brake cylinder.
The cylinder has a chamfer of 2x10 mm. This results in a transmission ratio of 5, meaning that when the
cylinder moves by 1 mm, the sensor signal changes by approx. 20 inc.
The device is configured in its new condition or after the brake pads have been replaced.
SSC1.1 issues a warning when the brake pads are worn by 3 mm, SSC1.2 issues a warning when the
brake pads are worn by 5 mm.

Parameter setting:
Install and connect the device.
Actuate the brake with the new brake pads.
Read the current process data value PDV and write it down (40 in the example).
SSC1.1 Config. Select Mode and set Single point.
Select SSC1.1 Config.Logic and set Low active. The output switches when the brake cylinder
moves too far away.
Manually set the switch point SP1 for switching channel SSC1.1: SSC1.1 Param.SP1 = 40 (PDV) + 60
(wear limit 1 = 3mm x 20inc/mm) – 10 (hysteresis) = 90.
SSC1.2 Config. Select Mode and set Single point.
Select SSC1.2 Config.Logic and set Low active. The device switches when the brake cylinder is not
detected.
Manually set the switch point SP1 for switching channel SSC1.2: SSC1.2 Param.SP1 = 40 (PDV) +
100 (wear limit 2 = 5 mm x 20inc/mm) – 10 (hysteresis) = 130.
Save the parameter set and write it to the device.
The reset point is taught according to the “Object Detection” function class and the Low ac-
tive logic.
