Torque adjustment
Only possible with VAR03. The brakes are
delivered adjusted with nominal torque value.
Principle of torque reduction
(See table 3 and Fig. 4). Unscrew the
adjusting cap located behind the inductor
without exceeding the dimension M min.

* NOTE
: for ERD 6400 & 12800 and ERDD 12800 & 25600, the torque is reduced by removing the springs. This operation is carried out in our plants.
6.2
Detection kit
Mounting:
Check that the brake is correctly adjusted with
nominal airgap. Fit the M6 screw in the moving
armature and mount the nut (see Fig. 5), fit the
sensor with the M3 screws and washers.
Adjustment
Insert a feeler gauge in gap X (see table 4)
between the inductor and the moving armature.
Switch the brake on, and adjust the screw until
you obtain action on the sensor, then tighten the
locking nut. Check the unit works correctly with
successive pull-in and pull-outs.
