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
which 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 normal 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 (3) 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.
