Introduction

When used with the Warner Octal Sockets, the
control meets the appropriate UL and CuL
certifications.

Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal injury to
personnel.

The CBC-802 is a solid-state clutch/brake control
designed for operation of all Warner Electric 90 volt
DC clutches and brakes with the exception of the
high torque series. It should not be used to directly
power Warner Electric permanent magnet electrically
released brakes as the units require an adjustable
current or voltage supply to provide optimum
release.

The CBC-802 clutch/brake control is a direct plug-in
replacement for the previous MCS-802-2 control.
The difference between the two versions is that the
CBC-802 has a potentiometer for adjustment of the
anti overlap between clutch and brake where the
MCS-802-2 was switch selectable for preset times
only. Additionally, the fuse changed for a 3AG type
for the MCS-802-2 to a 5mm type fuse on the
CBC-802. Also included in the CBC-802 are LED
indicators indicating when the brake or clutch is
energized.

The CBC-802 clutch/brake control is designed to
switch between a clutch/brake combination, two
clutches or two brakes, one unit on at a time.
Control design is such that on power up, the brake
channel energizes initially, with normal switching
inputs. The time delay feature is designed to
minimize clutch/brake interaction by reducing
clutch/brake torque overlap. Indicator LED’s on the
control show when the brake channel (RED) or
clutch channel (GREEN) is energized. An internal
fuse provides protection from overload conditions.
Additionally the control is protected against output
short circuit conditions. The control does not protect
from AC ground loops or faults on the DC output
side.
