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