Micro Switch (Option)

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 attracted 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.
Warning!
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).
