Introduction
Warner Electric's CBC-700 clutch/brake
control is a basic overexcitation control for
electromagnetic clutches and brakes.
Overexcitation, a momentary high voltage spike,
builds up electromagnetic flux very quickly in
the clutch and/or brake coil for quick
engagement and superior accuracy. The
CBC-700 works on the capacitive discharge
principle, boosting AC input voltage and storing
a high voltage pulse. No torque adjustment is
provided, so full torque is available from the
"on" clutch (or brake) by providing it with full
rated voltage. Two models of the CBC-700 are
available:
CBC-700-90 90 volt magnets
CBC-700-24 24 volt magnets
The CBC-700 requires only two adjustments.
Overexcitation pulse duration is adjustable in
seven ranges to custom tailor control function
for each application and to minimize coil
temperatures. A time delay between
clutch/brake engagement is also adjustable
between 0 and 100 milliseconds for the
CBC-700-90, and 0 to 50 milliseconds for the
CBC-700-24, by providing a rest period
between brake and clutch engagement. This
eliminates overlap and reduces heating and
wear of the clutch and brake units.
The CBC-700's sophisticated coil suppression
circuitry allows extremely short time delays and
quick response. Optically isolated switching
inputs promote full switching flexibility.
The CBC-700-90 incorporates several new
features:
A short circuit protection for the clutch and
brake outputs. If a short is present, an amber
L.E.D. will illuminate and the outputs will be
isabled. The short circuit L.E.D. is reset by
turning off the power to the control for 10
seconds.
• An O.E.X. on/off switch allows the user to
turn off the O.E.X. pulse for custom
applications.
• Two output L.E.D.s indicate when the brake
(red) or clutch (green) is on.

The voltages in this control can cause serious injury (even death). When installing
or wiring this control, make sure the input power is off, and main capacitors discharged. Do not
apply voltage to the control until it is securely mounted and completely wired in accordance with
local codes and all installation work, including cleanup, has been completed.

This is a floating-type control and is not referenced to AC ground. Under no circumstances should any of
the output wire leads be connected to earth or chassis ground
as the unit will be destroyed.

The chart below will be helpful when attempting to isolate problems which may occur in the control
system. It will also prove helpful when encountering problems during initial system start-up.
Symptom A: No output on either clutch or brake upon power-up.
Probable Cause Solution
Improper wiring Check wiring and correct if necessary.
No power available Check that AC power is available to control.
Blown fuse * See Fuse keeps blowing, Symptom C.
Faulty control Replace control.
Symptom B: Clutch activates upon power-up.
Probable Cause Solution
Improper wiring Check wiring and correct if necessary.
Faulty input switching circuit Check that input switching network is providing proper signal.
Symptom C: Fuse keeps blowing.
Probable Cause Solution
Improper wiring Check wiring and replace fuse.
Shorted brake/clutch coil Check coil resistance and replace if necessary.
Ground Fault Check coil to earth ground resistance.
Improper AC line voltage Check line voltage and correct if necessary.
Improper magnet voltage Check magnet voltage rating and replace with correct magnet if necessary.
Symptom D: Magnets do not appear to have enough torque.
Probable Cause Solution
Improper OEX switch setting Set pulse duration switch settings according to setup chart.
Magnets incorrectly sized Verify sizing by repeating the selection process.
Symptom E: Outputs don't switch; Inputs don't switch.
Probable Cause Solution
Incorrectly wired inputs Check wiring and correct if necessary.
Faulty switching device Check for proper operation and replace if defective.
Faulty control Replace control.
Symptom F: Switching time too long or too short.
Probable Cause Solution
Improper overlap pot setting Set overlap according to setup chart.
Symptom G: Amber L.E.D. illuminated *
Probable Cause Solution
Improper wiring Check wiring and correct if necessary.
Shorted brake/clutch coil Check coil resistance and replace if necessary.
Faulty control Replace control.
* Turn off power to control for 10 seconds to turn off amber L.E.D.
