TROUBLE SHOOTING
A. IF BRAKE DOES NOT RELEASE:
1.
Check brake visually for broken or damaged
parts.
2.
Check for broken leadwire or bad electrical
connection.
3.
Check for correct voltage. Line voltage must
correspond to the voltage for which the
brake coils are connected. If the line voltage is
more than 10% below the voltage for which
the brake coils are connected, the magnet
will not pull in, causing the coils to burn out
within minutes. If the line voltage is more than
10% above the voltage for which the brake
coils are connected, the coils will overheat
and burn out.
4.
Check for burned-out coils (coils may be
charred or burned).
5.
Check for excessive magnet gap. (See WEAR
ADJUSTMENT.)
6.
Check for failure or power supply to brake.
B. IF BRAKE DOES NOT STOP:
1.
Check brake visually for broken or damaged
parts.
2.
Make certain hub has not shifted position on
the motor shaft and that all rotating discs are
fully engaged on the hub.
3.
Check that the manual release is in the
normal position.
4.
Check disc wear. (See WEAR ADJUSTMENT.)

C. IF BRAKE CHATTERS OR HUMS:
1.
See that magnet faces are clean. To remove
dirt, insert a clean sheet of paper between
magnet faces and energize brake. Move paper
around between faces to dislodge dirt, then
remove paper.
2.
Check for low voltage. Magnet will not pull in,
and coils will burn out if line voltage is
beyond 10% below the voltage the brake coils
are connected for.
3.
See that magnet faces are parallel within
tolerance. Readjust magnet gap to "D" min.
(See WEAR ADJUSTMENT.)
4.
Check if shading coil (20) is cracked, broken
or out of position (single phase only).
D. IF MANUAL RELEASE DOES NOT WORK:
1.
Check for broken or damaged parts.
2.
Check return spring (11). Brake will not reset
automatically if this spring is broken.
3.
Check quantity of shim washers (13) under
release stop screws. (See MANUAL RELEASE
ASSEMBLY.)
