Please note: this is a Fail Safe Brake and "fails to safety" when there is a power failure.
When locking handles are used this disables the Fail Safe system and we do not
recommend using them.
9.4
If strong temperature fluctuations are expected, a condensation heater (30) may be used to
prevent the generation of condensation water. A special feed line will be provided accordingly.
In case of questions please contact the manufacturer.
9.5
If a speedometer connection is required for the brake, the brake is provided with a tacho flange
(12) with connecting bores in accordance with „Euro dimensions" (Diameter 85/100).
It is recommended to connect the tachometer or the encoder to the shaft through a plug-type
coupling.
Caution!
The type of protection only maintains when the speed encoder is rigidly connected to the cover
by means of a flange gland which is sealed by round ring.

Optionally the brake can be equipped with a self -
locking hand lever release allowing the manual
release in case of emergency, e.g. current failure.
By pulling the hand lever (4) at approx. 30°
towards the back of the brake the armature disc
(10) is moved axially until it is lying against the coil
body (1) thus the friction disc lining may rotate
freely. The handle (4) must be screwed in at this
position to operate the locking mechanism. Please
ensure brake is fully released. Then screwed out to
release.
Please note: the cap screws (50) can be removed
and the emergency release screws can be fitted
(see chapt. 4.3) to release brake (this is
recommended method of brake release).
