Warner Electric Electrically Released Motor Brake Module for EM-MBFB and EUM-MBFB - Manual (Page 3)

3 Warner Electric • 800-825-9050 P-1337 • 819-0314
24 Volt Brake recommended controls are:
CBC-500-24, 24-30 VAC input
part no. 6024-448-002
CBC-550-24, 120/220/240/380/480 VAC input
part no. 6024-448-005
All Permanent Magnet type
Electrically Released Brake Modules are
polarity sensitive. See the service installation
sheet included with the control for connection
information.
Burnishing and Maintenance
No burnishing required, units are pre-burnished at
factory.
As with any friction-type device, some initial
concern should be given to wear rate.
Improper voltage setting can reduce the braking
life. Once the best release voltage has been
established, precautions should be taken to
prevent machine operators, or other personnel not
familiar with wear characteristics, from changing
the potentiometer setting arbitrarily.
To reach the normal wearing components, reverse
the installation procedure for the module assembly.
Wear Pattern
Wear grooves appear on the friction surfaces. This
is a normal wear condition, and does not impair
functioning of the unit. Never machine the friction
surfaces to remove grooves or score marks
resulting from normal wear.
Heat
Excessive heat and high operating temperatures
are causes of rapid wear. Units, therefore, should
be ventilated as efficiently as possible, especially if
the application requires fast, repetitive cycle
operation.
Step 2: Electrical Connections
The conduit hole in the motor brake is threaded
for standard pipe conduit connectors. The wiring
diagram included with each Warner Electric control
shows the proper electrical connections to be made.
Note: Controls used must have adjustable
output voltage.
Connect the red wire from the unit to the “+”
terminal of the DC supply and the black wire from
the unit to the “-” terminal of the DC supply.
Note: Refer to the brake release adjustment
process on page 4.
Control Requirements
All Permanent Magnet Type Electrically Released
Brake Modules are polarity sensitive. Therefore, the
(+) red wire must be connected to the (+) terminal
and the (-) black wire to the (-) terminal.
Potentiometer control will then provide adjustment
for the proper brake release point as described in
the “brake release” procedure.
See the service installation instruction provided with
controls for connection information.
