Operation of sensor
There are two micro switches in the housing of the
sensor. The spacer pin activates the switches in two
different positions.

status of the brake.

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, there is no signal.
„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 signal status „resetting necessary“ is acti-
vated.
Brake pads having a balance of pad height of less than 2 mm have to be replaced by return.
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.
