TROUBLESHOOTING
BRAKE DOES NOT RELEASE
Check for failure of power supply to brake.
Check brake visually for broken or damaged parts.
Check for broken leadwire or bad electrical connection.
Check for correct voltage. Voltage must correspond to that listed
on brake nameplate. If voltage is more than 10% below figure
stamped on nameplate, magnet will not pull in, causing coil to
burn out within minutes. If voltage is more than 10% above,
coil will overheat and burn out.
Check for burned out coils (coils may be charred or burned).
Check for excessive magnet gap (See WEAR ADJUSTMENT).
BRAKE DOES NOT STOP
Check manual release. Drive gear must be turned completely
clockwise.
Check thermal release. Release may have tripped.
Check brake visually for broken or damaged parts.
Check disc wear (See WEAR ADJUSTMENT).
Check for broken friction disc.
Make certain hub has not shifted position on shaft and that all
rotating discs are fully engaged on hub.
BRAKE CHATTERS OR HUMS
Clean magnet faces if dirty. Insert a clean sheet of paper between
magnet faces and energize brake. Move paper around between
faces to dislodge dirt. Finally, remove paper.
Check that magnet faces are parallel in closed position. If not
parallel along length of magnet, adjust (See WEAR
ADJUSTMENT).
Check if shading coil is cracked, broken or out of position.
Check for low voltage. Magnet will not pull in and coil will burn
out if voltage is more than 10% below figure stamped on
nameplate.
