Dings Dynamics Group 60 Series Coupler NEMA 2 - Manual (Page 3)

For models with one-piece shaft design:
1. Place 3/16” square key furnished into motor keyway.
Key must extend to, and be flush with, end of motor
shaft. For enclosed housing models (4-60000-553), place
gasket (34) on motor C face.
2. Place brake assembly onto the motor shaft, aligning
the brake shaft keyway with key in the motor shaft. If
the key wants to ride up at the end of the motor shaft
keyway, push the key into the brake shaft with a
screwdriver.
Do not use excessive force to seat the brake against the
motor. If excessive force is required, the key may have to
be filed.
Brake bracket (1) must be flush with the motor mounting
face and adapter housing (7) must seat against the
bracket (1).
NOTE: Arrow head on adapter housing should be in line
with manual release knob (15); see Fig. 10. The release
should be located at the top.
3. Screw in four 3/8-16 threaded rods (28) or (32) through
housing (7) and bracket (1) into motor C face (approx.
9/16” engagement or 9 turns).
4. If additional equipment is to be used, such as a gear
reducer, install a key into the brake shaft extension. For
enclosed housing models (4-60000-553), install gasket
(34) onto the brake C face.
Slide equipment onto threaded rods, aligning key in the
brake shaft with keyway in the equipment. Fasten with
lockwashers (29) and nuts (30).
5. If no additional equipment is used, fasten brake assembly
with items (29) and (30). The threaded rods may be cut
off to suit the application.
Connection of Coil Leads
After securing the brake to the motor, connect coil leads
for proper voltage per wiring diagram. (Fig. 2 shows dual
voltage coil). Incorrect connection can result in brake failure.
CAUTION: The voltage supplied to the coil must match
the voltage that the coils are connected for, or the coils
will burn out.
Single voltage coil:
Connect brake coil leads to any two line leads (single or three
phase) of same voltage and frequency as brake.
Dual voltage coil:
Connect leads 2 and 4 to any two motor line leads (single or
three phase) of same voltage as brake. Connect leads 1 and 3
as shown for voltage desired. Brake must be energized with
motor.
OPERATION
These brakes are spring set devices with an electrical
(magnet) release. They contain a rotating friction disc
that is driven by a hub mounted on the motor shaft. When
energized, the magnet compresses the torque springs,
removing the force pressing the stationary disc and friction
disc together. This permits free rotation of the shaft.
WARNING: Observe proper safety precautions in
applications where a brake failure would allow the load
to move in such a manner as to injure personnel.
KEEP PERSONNEL AWAY FROM LOAD AREAS.
If brake torque rating is higher than motor full-load torque
rating, use brake rating rather than motor rating when
selecting other drive components.
Take the following precautions when operating the brake:
1.
Do not operate the brake at higher than nominal static
torque capacity.
2. For applications with high inertia-type loads or rapid
cycling, the thermal capacity of the brake must be
considered.
3. High start-stop rates may damage motor. Consult motor
manufacturer if high cycling rates are expected.
4. Be sure power supply conforms to electrical rating of
brake.
Manual Release
The brake is equipped with a manual release. Turn the release
knob (15) clockwise to stop position to release the brake. The
brake will remain released until the release knob is turned
counterclockwise (approx. 65
o ) or until the brake coil is
energized, automatically resetting the brake.
