1.8Brake Assembly Instructions (Reference Drawing: 0040-0023-C)

IMPORTANT: Unless specified, the replacement brake assembly does not include a solenoid or a brake drum. If these items are required, they must be requested separately, please specify the motor voltage.

WARNING: DISCONNECT BARRIER POWER BY THROWING THE MAIN POWER SWITCH (S1) OFF BEFORE REMOVING THE OLD BRAKE ASSEMBLY.

Item numbers refer to the brake drawing included in the major components section of this handbook.

To remove the old assembly:

1.Remove the Brake Release Stub (Item 9) from its bracket.

2.Remove the Brake Drum (Item 2) set screw. The set screw is located on the side of the brake drum, even with the key in its center.

3.Pull the drum off of its shaft.

4.Disconnect the wires from the brake release solenoid (Item 5).

5.Remove the brake assembly mounting bolts, and lift off the brake assembly.

To mount the new assembly:

1.Place the new brake assembly on top of the motor, align the mounting holes, and tighten the mounting bolts.

2.Unless a new solenoid was requested, the brake solenoid from the old brake assembly will need to be re-mounted on the new assembly.

∙Disconnect the solenoid arm from the solenoid release rod (Item 7).

∙Remove the solenoid mounting screws.

∙Place the solenoid (Item 5) on the new brake assembly, align the holes and replace the mounting bolts.

∙Reconnect the solenoid plunger to the solenoid release rod.

∙Reconnect power wires to the solenoid.

3.Insert the brake drum onto the keyed shaft and tighten the set-screw.

4.Re-install the manual release stub onto its mounting bracket.

5.Re-apply power to the barrier, and test the brake by running the operator.

6.If the solenoid makes a loud buzzing sound, it is binding and needs to be adjusted.

∙Loosen the mounting bolts and activate the operator. The solenoid should seat itself properly.

∙Re-tighten the mounting bolts.
