NEMA 4 & NEMA 4X Enclosure

Bulletin No. BK4660 (8/07)

DESCRIPTION

These magnetic disc brakes are direct acting, electromagnetically released

and spring set. They use rotating friction and stationary disc contact to

supply positive brakeing action. They mount directly onto NEMA 56C,

143TC, and 145TC frame motors, on the end opposite the drive shaft.

Models 6-60000-543 and 6-60000-5115 are mounted directly to a motor

where a gasket between the brake and motor face prevents liquid media

from enering the brake.

Models 4-60000-530 and 6-60000-5116 are for TEFC motors or foot

mounting applications; brake design with hub seal prevents liquid media

from entering the brake through opeings in the motor fan cover or foot

mounting bracket.

Models 6-60000-543 and 4-60000-530 are standard end-mount series

NEMA 4 Enclosure.

Models 6-60000-5116 and 6-60000-5115 are washdown NEMA 4X end-

mount series (BISSC Std. #29).

WARNING: Do not install or use these brakes in

an explosive atmosphere.

Bulletin No. BK4660 (8/07) 60 Series End-Mount Brake Instructions NEMA 4 & NEMA 4X Enclosure Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage! Retain instructions for future reference. DESCRIPTION NEMA 4 NEMA 4X These magnetic disc brakes are direct acting, electromagnetically released and spring set.
PAGE 2
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.
PAGE 3
INSTALLATION CAUTION: To preserve pre-alignment of rotating discs for ease of installation, do not operate manual release or energize brake coil before installation. NOTE: The brakes are designed for horizontal mounting. Modification is required for vertical mounting. Brakes that are modified will have a prefix on the model number of VO (Vertical Over) or VU (Vertical Under). Numbers in parentheses refer to parts illustrated in Figs. 2, 4 and 10.
PAGE 4
Figure 4 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.
PAGE 5
MAINTENANCE CAUTION: Before attempting to service or remove any components, make certain that the power is disconnected and that the load is completely removed, secured or blocked to prevent injury or property damage. Wear Adjustment CAUTION: Load to be removed or blocked. Brake will be inoperative during this procedure. Refer to Fig. 4. Before air gap “A” reaches .100”, adjustment is required. Any delay in adjusting the magnet air gap will result in eventual loss of torque. 1.

Figure 5 Magnet Assembly Replacement Armature Replacement CAUTION: Load to be removed or blocked. Brake will be inoperative during this procedure. CAUTION: Load to be removed or blocked. Brake will be inoperative during this procedure. Refer to Figs. 4, 6, and 10. 1. Disconnect power supply. 2. Remove acorn nuts (23), washers (22), and pull cover (20) off. (You may have to tap lightly with a rubber mallet. 3. Remove two capscrews (15D), magnet assembly (15A), and shock mount (15B). 4.

Manual Release Assembly Manual Release Adjustment Refer to Fig. 7. CAUTION: Load to be removed or blocked. Brake will be inoperative during this procedure. The manual release (3) may require adjustment after replacing the operator assembly (15), magnet (15A), or armature (15J). It also may be required if adjustments are made on the pivot stud nuts (19).

TROUBLESHOOTING CHART SYMPTOM Brake does not release Brake does not stop properly Brake chatters or hums Manual release does not work 8 POSSIBLE CAUSE CORRECTIVE ACTION 1. Broken or damaged parts 1. Replace. 2. Wrong voltage 2. Check for correct voltage. Voltage must correspond to that listed on brake nameplate. If the voltage is more than 10% below the nameplate voltage, the magnet may not pull in. 3. Burned out coil 3. Replace magnet assembly (15A). 4.

VERTICAL MOUNTING Installation and adjustment of the vertically mounted brake is the same as on the standard model. Friction Disc Replacement When replacing friction discs, follow procedure outlined on page 5 with this addition: Care must be taken to insure proper insertion of disc separating springs. Springs are color coded for easy identification, and reference is made to spring color (see Table 1 and Figure 9).
