Application
ROBA
®
-brake-checker plus AC monitoring modules are
used to supply permitted ROBA
®
-stop safety brakes.
Motion monitoring of the armature disk for released ROBA-
stop
®
safety brakes is possible.
Monitoring module ROBA
®
-brake-checker AC
• Sensorless and contactless detection of switching statu-
ses
• Preventative function monitoring (wear recognition and
error recognition, functional reserve)
• Brake condition recognition (release and drop-out recogni-
tion of the armature disk)
• Continuous drop-out recognition
• Simple installation or retrofitting
• Electrical isolation on the output channels
• Maximum current I
max
= 3.5 A
Function
The ROBA
®
-brake-checker AC monitoring module is
designed for the connection to half-wave or bridge rectifiers
or to fast acting rectifiers based on half-wave or bridge
rectification which are supplied with alternating voltage
(50/60 Hz).
The module is switched between the rectifier and the
brake and it monitors the movement of the armature disk.
The determined switching condition is emitted via control
terminal 3 (output signal). Critical conditions (line breakages,
wear) can be recognised and the respective signal can be
emitted via control terminal 4 (output error).
The movement detection feature of the armature disk is
based on the detection of electromagnetic changes in
the brake. If, due to unfavourable external influences, the
secured detection cannot be ensured, it is possible that the
signal and error outputs do not correspond to the expected
state (plausibility).
