Function
The ROBA
®
-brake-checker plus AC monitoring module is
intended for use with an input voltage of 200 to 480 VAC.
The monitoring module supplies the connected brakes and
regulates to a permanently programmed overexcitation
voltage. After the overexcitation time ends, it regulates to
the permanently programmed holding voltage.
The overexcitation time is set automatically.
The monitoring module monitors the movement of the arma-
ture disk and emits the determined switching condition via
control terminal 3 (signal output).
Critical conditions (line breakages, wear) can be recognized
and the respective signal can be emitted via control terminal
4 (error output).
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).
CAUTION
The ROBA
®
-brake-checker cannot be used
in all applications (e.g. when operating
noise-damped brakes, it cannot be used
without additional measures). The product’s
suitability should be checked before use.
Application
ROBA
®
-brake-checker plus AC monitoring modules are
used to connect permitted ROBA
®
-stop safety brakes to AC
voltage.
Motion monitoring of the armature disk for released ROBA-
stop
®
safety brakes is possible.
