Date 8/80
IMPORTANT
Read this bulletin carefully before installing or operating
this- brake. Failure to :comply with these instructions
cancels all warranties.
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 hot 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 minimum. As with any electromechanical
equipment, however, periodic inspection and adjustment
will assure optimum performance. As the friction discs
wear, the magnet gap will increase. the magnet gap
should be checked periodically and adjusted when
necessary.
INSTALLATION (see Figures 2,4 & 5
1. Remove hub (1) from brake and position on motor
shaft with key as illustrated in Figure 2. Stamped part
number on hub should face away from motor. Tighten
hub screws to shaft with 8-10 lb. ft. torque.
2. Remove two cover screws (32) and cover (31) and
position brake over hub on shaft. Bolt brake to motor
flange or floor mount.
3. connect coil wire leads as shown in Figure 4.
Replace cover and cover screws.
