Warner Electric CBC-802 User Manual

There are switching options that can be used with
the CBC-802 clutch/brake control. Determine
which switching option you will be using and wire
the switching inputs for that option.
Option 1 – Momentary Push Button Switches
1. Connect the normally open start switch
contacts to terminals 7 and 8 of the socket.
Tighten terminal 8 securely.
2. Connect the normally open stop switch
contacts to terminals 7 and 3 of the socket.
Tighten both terminals securely.
3. This completes the wiring of the CBC-802.
Double check all terminal wiring at this time
Proceed to the start-up section of this
manual.
Option 2 - 2-wire Maintained Switching
When using option 2 for switching input, the
switch wiring must be such that in normal state the
contacts are closed at power-up to insure brake
output is energized. Switching can be either
through a maintained type switch or relay contacts
as shown above.
1. Connect a jumper wire from terminal 7 to
terminal 8 of the socket. Tighten terminal 8
securely.
2. Connect the normally closed switch or
normally closed relay contacts to terminal 7
and terminal 3 of the socket. Tighten both
terminals securely.
3. This completes the wiring of the CBC-802.
Double check all terminal wiring at this time.
Proceed to the start-up section of this
manual.
Option 3 - Solid State Switching – NPN Open
Collector Logic
When using solid state switching,
the emitter or output common of the switching
device cannot be grounded. If the outputs are
grounded, then either different switching
devices must be used or an input isolation
transformer on the AC input to the CBC-802
must be used, or the CBC-802 will be
destroyed.
1. Connect the collector of the NPN output
transistor or switching device to terminal 3
of the socket for stop input. Tighten terminal
3 securely.
2. Connect the collector of the NPN output
transistor or switching device to terminal 8
of the socket for start input. Tighten terminal
8 securely.
3. Connect the emitter of the NPN output
transistors or switching device common for
both stop and start to terminal 7 of the
socket. Tighten terminal 7 securely.
4. This completes the wiring of the CBC-802.
Double check all terminal wiring at this time.
Proceed to the start-up section of this
manual.
