MANUAL RELEASE

(See Figure 4)

To operate release, rotate two nuts (16) clockwise until stop

screw (14) hits pin. Brake will remain in released position until rods

are manually returned to original position, or until electrical power

is restored, automatically resetting the brake.

TORQUE ADJUSTMENT

(See Figures 2 & 4–Table 1)

Brake is factory set for rated torque per spring length "H". To increase

stopping time and lower torque, turn two locknuts (9) counterclockwise,

increasing dimension "H". Both springs must be set to the same length.

Do not decrease spring length "H" as this may cause coil to burn out.

MAINTENANCE AND SERVICE

WEAR ADJUSTMENT

(See Figures 2 & 4– Table 1)

Magnet gap "D" increases as friction discs wear. When gap approaches

"D" max., adjust gap to "D" min. dimension by turning nuts (23 and 24).

Magnet gap can vary from nominal + .005" between corners. After

setting gap, readjust torque spring length "H".

CAUTION: MAGNET GAP MUST NOT EXCEED

"D" MAXIMUM.

FRICTION DISC REPLACEMENT

(See Figure 4 & Table 1)

When the rotating friction disc (4) wears down to a thickness of 7/32",

replace disc. Remove brake from its associated equipment (reducer-

motor-etc.). Remove retaining ring (28) and press shaft (1) out of bear-

ing in brake case (25). A wheel puller, utilizing openings in side of

case, can be used. Continue disassembling in this order: two nuts (26),

brake case (25), roll pins (17), manual release knobs (16), manual

release screws (14), manual release washers (12), manual release

shims(13), two nuts (24), magnet mounting plate assembly (18), two

nuts (23), two nuts (9), torque spring washers (8), torque springs (7),

pressure plate assembly (6) and discs (4) (5).

Lay bracket (2) on a flat table. Place shaft (1) in center of bracket, with

a spacer under hub. Spacer thickness to be 13/16". Replace worn

friction discs (4) and reassemble disc pack. Continue reassembling in

reverse order, setting torque spring dimension "H," and magnet gap "D"

min. (Table 1.). When assembling manual relase, turn release rod (10)

counter-clockwise until screw (14) strikes pin. Wind torsion spring (11)

about 1/4 turn and hook spring over pin.

NOTE:

When assembling manual release mechanism, add only

enough shim washers (13) to obtain proper release action.

With too many shim washers, brake will not automatically reset when

electrical power is applied. With too few shim washers, motor shaft will

not turn freely with brake in manually released position.

IMPORTANT: Make sure release is working properly

before proceeding.

Place case (25) over shaft (1). Release brake by turning two nuts (16)

clockwise. Press bearing (in case) onto shaft by applying pressure to

bearing inner race. Complete assembly in this order: snap ring (28)

and two nuts (26).

NOTE::

Units with 1-3/8" dia. output shafts–remove brake case by

first removing outside retaining rin (41) and two nuts (26).

Then press shaft (1) out of bearing. Next remove remaining retaining

ring (41) and pull shaft out of brake.
