MANUAL RELEASE
(See Figure 4)
To operate release, rotate two knobs (18) clockwise until stop
screw (16) 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 (22) counterclock-
wise, 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 (28 and 29).
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 (3) wears down to a thickness of 7/32",
replace disc. Remove brake from its current mounting location and any
parts mounted to double shaft ends. Remove lock collar on bearing (23
or 37) on housing adaptor side only. Continue disassembling in this
order: two nuts (28), adaptor housing (7), roll pins (19), manual release
screws (16), manual release washers (14), manual release shims (15),
two nuts (19), magnet mounting plate assembly (6), two nuts (29), two
nuts (22), torque spring washers (11), torque springs (10), pressure
plate assembly (5) and discs (4) (3).
Replace worn friction discs (3) 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 (12) counter-clockwise until screw (15) strikes pin.
Wind torsion spring (13) about 1/4 turn and hook spring over pin.
NOTE:
When assembling manual release mechanism, add only
enough shim washers (15) 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 relase is working properly before proceeding.
Place adaptor housing (7) over shaft (8) and complete assembly with
two nuts (28) before tightening lock collar on bearing (23 or 37).
Release brake by turning two knobs (18) clockwise.
