Brake torque reduction (for the optional adjustable braking torque)
Fig. 39:
Reducing the braking torque
1. Use a hook wrench to turn the torque adjustment ring counter-clockwise. This reduces the braking
torque.
– Note the correct position of the tappet notches on the torque adjustment ring: Only the latched-in
positions are permitted. It is forbidden to operate the brake when the notches are adjusted between
these latched-in positions! (Refer to chapter Brake torques, Page 22 for the values for the braking
torque reduction for each latched-in position.)
– Observe the max. permissible protrusion (h
Emax
) of the torque adjustment ring over the stator. (Refer
to the table Rated data for braking torques, depending on the speed and permissible limiting
speeds for values of h
Emax
.)
DANGER
The reduction of the braking torque does not increase the maximum permissible air gap s
Lmax
.
Do not change the hand-release setting for designs with hand-release.
Increasing the braking torque by screwing in the torque adjustment ring is only permitted up to
the default (as delivered) torque value .

DANGER
The friction lining and the friction surfaces must never contact oil or grease since even
small amounts reduce the braking torque considerably.
