Switch S2 only shows the wear status reliably when the brake is activated (locked). If the brake is not activated
(unlocked), a statement about the condition of wear cannot be given.
The wear of the brake pad is only measured if the brake is activated. If the brake is not acti-
vated, the signal (2 - 3) is present.
„Resetting necessary“ is displayed as soon as the brake pad has worn off in that resetting
has become necessary.
!
The brake pad has to be reset as soon as the status of the signal (2 -
5) „re-adjustment ne-
cessary“ is activated.
Brake pads having a balance of pad height of less than 13.5 mm have to be replaced by re-
turn. Please note chapter 5.1 Replacement of brake pads.
Fail-safe operation
A proper operating condition is only ensured if the state/wear sensor is wired properly. This provides a signal
since a switch (NO) is locked which is normally unlocked.
!
In case of damages like, for example, faulty cables, bad connections, etc. the signals need
to disappear.

Illustration 20: Pin assignment of plug-in connection
•
Remove the screw plug (component 1.20) from the connection co-
ver (component 1.6).
•
Mount the sensor housing (component 4) in the housing cover
(component 1.6).
•
Hand-tighten the sensor in the sensor housing (component 4) first
(see illustration 21).
•
Tighten the sensor at the tightening torque T
A
= 20 Nm.
Illustration 21: Assembly of state/wear sensor
In case of heavy vibrations the sensor has to be
secured against working loose.
•
Provide for the electric connection according to the plug-in connec-
tion (see illustration 20).
