8.2 Torque Adjustment
Some models of the COMBISTOP have the option to manually reduce the braking torque
by adjusting the E-Ring or Set screws holding the springs in place. To reduce the braking
torque, adjust the E-Ring or Set screws away from the magnet by ¼ turn at a time. The
distances to adjust the E-Ring or Set screws for the desired torque reduction are given in
the graph below, as well as the maximum permissible adjustment distances.
•
COMBISTOP sizes 02 – 06 use an adjustable E-Ring to reduce braking torque. The
entire E-Ring can be rotated to adjust the torque.
•
COMBISTOP sizes 07 – 11 use set screws to reduce braking torque. All set screws
should be turned the same number of rotations to ensure even braking torque.

CAUTION
Imprecise Measurements
The torque measurements listed in the graph below are
approximations and will vary dependent on environmental variables.
Take care to measure actual braking torque when adjusting the E-
Ring or Set screws.
