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).
BRAKE DOES NOT STOP
Check brake visually for broken or damaged parts.
Check disc wear (see WEAR ADJUSTMENT).
Check for broken friction disc.
Check hub. Be certain hub has not shifted position on shaft
and rotating disc is fully engaged on hub.
BRAKE CHATTERS OR HUMS
Clean magnet faces if dirty. Insert a clean sheet of paper
between the magnet faces and energize brake. Move
paper around between faces to dislodge dirt. Finally,
remove paper.
Check if shading coil (23) 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.
MANUAL RELEASE DOES NOT WORK
Check for broken or damaged parts.
Check return springs (18). Replace if broken.
Check magnet air gap “A” with lever in the normal position.
Gap must be .060” at narrowest point. If gap is too small,
motor shaft will not turn freely.
Adjust to correct magnet gap as described under WEAR
ADJUSTMENT.
