WARNING
Brake performance and features must be carefully matched to the requirements of
the application.
Consideration must be given to torque requirements, especially where an
overhauling condition exists, as well as thermal capacity, ambient temperature,
atmospheric explosion hazards, type of enclosure and any other unusual conditions.
Improper selection and installation of a brake and/or lack of maintenance may cause
brake failure which could result in damage to property and/or injury to personnel.
If injury to personnel could be caused by brake failure, additional means must be
provided to insure safety of personnel.
Do not operate manual release or energize brake coil before installation, in order to
preserve prealignment of rotating discs for ease of installation.
DESCRIPTION
This brake is direct acting, electromagnetically released and spring
set. It uses rotating and stationary disc contact to supply positive
braking action. It retains quick release and setting capabilities at all
times.
Simplicity of design has reduced maintenance to an absolute mini-
mum. As with any electromechanical equipment, however, periodic
inspection and adjustment will assure optimum performance. As the
friction disc wears, the magnet gap will increase. The magnet gap
should be check periodically and adjusted when necessary.
