MOUNTING
4.3 Micro switch (option)
The micro switch can be used for anchor position monitoring or as wear monitoring.
4.3.1 Micro switch as anchor position monitoring (default)
A micro switch can be used to monitor the switching state of the armature (brake open/
closed). The user is responsible to connect the electrical equipment and to evaluate the
signals! The drive control must not allow the motor to start until the armature was attract-
ed by the magnet, i. e., the lining can rotate freely.
The micro switch is factory-mounted to the brake as well as factory-set and secured.
cAUTION
In the event of any malfunction affecting the switching function, check the micro switch
settings and, if necessary, replace the micro switch (see sections below).
4.3.1.1 Checking the micro switch setting for anchor position monitoring
cAUTION
By repeatedly switching the brake, check the two switching states:
► Brake energised: ON signal (micro switch closed)
► Brake de-energised: OFF signal (micro switch open)
4.3.2 Micro switch for wear monitoring
The wear of the brake can be monitored by a micro switch. The switching point of the
micro switch is set below the wear limit, by way the micro switch emits a signal before
functional failure of the brake.
The user is responsible to connect the electrical equipment and to evaluate the signals!
The micro switch is factory pre-assembled on the brake, preset and secured
4.3.3 Adjustment and change of the micro switch
Adjustment and replacement of the micro switch may only be carried out by qualified per-
sonnel!
brake malfunction!
Changing the settings of the micro switch may cause drive / brake mal-
functions.
Loss of braking efficiency!
Before checking the micro switch settings, mechanically secure the load
against unintended movements and disconnect the brake from load!
