Release Monitoring
The brakes are supplied with manufacturer-side installed and
adjusted release monitoring device.
The microswitch (11.1) emits a signal for every brake condition
change: "brake opened or brake closed"
The customer is responsible for a signal evaluation of both
conditions.
From the point at which the brake is energized, a time span of
three times the separation time must pass before the switch
signal on the release monitoring is evaluated.
Fig. 10
Function
When the magnetic coil (2.1) is energized in the brake body (2),
the armature disk (14) is attracted to the brake body (2), the
microswitch (11.1) emits a signal, the brake is released.
When actuating the hand release (18), a
switching signal of the release monitoring
device (11) cannot be guaranteed.

Customer-side Inspection after Attachment
For customer-side connection as NO contact.
Brake de-energized
Signal "OFF",
Brake energized
Signal “ON”
For customer-side connection as NC contact.
Brake de-energized
Signal “ON”,
Brake energized
Signal “OFF”
Microswitches cannot be guaranteed fail-safe.
Therefore, please ensure appropriate access
for replacement or adjustment.
The switching contacts are designed so that
they can be used for both small switching
powers and medium ones. However, after
switching a medium switching power, small
switching powers are no longer reliably
possible.
In order to switch inductive, capacitive and non-
linear loads, please use the appropriate
protection circuit to protect against electric arcs
and unpermitted loads!
