Electromagnetic Double Face Spring – Applied Brake
9.1
If the switching condition of the brake should be controlled, a micro switch (28) could be used.
When the armature disc (10) is moved against the coil body (1) as a result of the
electromagnetic force of the coil or the actuation of the mechanical emergency release device,
(chap. 4.3), it will operate a micro switch (28) via set screw (64). The micro switch (28) may be
included in the control circuit of the motor contactor as a normally open or normally closed
contact.
The micro switch is preset in our works and should not require adjustment. If
replacement of the micro switch is required this must be done by our agreed procedure
(096-701:181)
9.2
The torques given in the technical data
(chap. 1.1.) were obtained only by fully tightening
the adjusting ring (14). By turning the adjusting ring
(14) this changes the pre-load of the cylindrical
pressure springs (21) and the brake torque is
altered accordingly.
The
dimension X and the respective torque rating.
These are approx. figures only
