Introduction
Warner Electric’s CBC-300 series Constant Current Clutch Brake Controls are solid-state electronic power supplies designed to operate any of the Warner Electric 90 Volt clutches and brakes, including fail safe designs. They can operate a single clutch or brake, two clutches, two brakes, a combination clutch and brake, or a combination clutch and fail safe brake, depending on the switching arrangement used and the application requirements.
The CBC-300 series controls operate from 120 VAC single-phase input power. They provide constant current output as set by the torque adjustment potentiometers on the front panel or remote potentiometer. Additionally, on some versions a level adjust can be used to set the operating level with the torque adjustment setting the maximum current level. On the CBC-300 series both outputs are adjustable. Output current ranges are selectable for the adjustable output channels in one of five ranges by the DIP switches located on the control’s printed circuit board.
Several versions of the CBC-300 are provided to handle a wide range of applications. These include both enclosed and chassis mount versions for mounting in an external enclosure
or control panel. The standard version is offered the same as before, but with the chassis version added. The CBC-300-1 and CBC-300-C1 versions are being offered where an external limit adjustment potentiometers are required. The CBC-300-2 and CBC-300-C2 versions maintain the limit adjust potentiometers on the PC board but allow for an external potentiometer for level adjustment of the output. This allows the output to be controlled from zero to maximum level on both the current adjusted output channels. The CBC-300-3 and CBC-300-C3 allow for both the current limit and level adjustment potentiometers to be mounted remotely.
Operations of all units are identical except for the method of the control potentiometer mounting. All units that have external potentiometer options have terminal blocks mounted on the PC boards for connection of the potentiometers.
The potentiometers used can be supplied either as optional accessory items or be obtained from a local electronic supply house.
No protection is provided for line to ground shorts because the unit is not isolated.
Two LED indicators are provided on the front panel of the control for "POWER" and "SHORT" indications. The green indicator marked "POWER" is illuminated whenever the AC input power is applied to the control. A red indicator marked "SHORT" is illuminated whenever a short circuit condition occurs in either of the outputs. To reset, power must be removed, the shorted condition cleared, and the AC input power reapplied to the control.
The enclosed version may be used with or without the cover. Removal of the plastic cover when the control is used in an enclosure will increase the operating temperature range of the control.
The chassis mount version does not have a cover and must be mounted in an enclosure or control panel.

Any vertical, horizontal, or angled surface is suitable for mounting the CBC-300-C, CBC-300-C1, CBC-300-C2, or CBC-300-C3 control.
Follow these procedures to mount your control:
q 1. Determine the mounting location where the
control will be placed.
q 2. Layout the mounting hole dimensions and
drill holes and taps using a 4-40 tap. Two options exist for mounting. The panel can be drilled and tapped for mounting or through holes can be used. (See Figure 2)
q 3. If the CBC-300-C1, CBC-300-C2 or
CBC-300-C3 controls are used, wire the external potentiometers to the appropriate terminal blocks as shown.
q 4. Place the faceplate over the PC board
assembly aligning the holes on the faceplate with the holes on the PC board.
q 5. Using the 4-40 screws supplied, mount the
PC board and faceplate assembly to the panel. Insure that the faceplate aligns correctly and does not contact any of the components on the PC board.
q 6. Tighten all four mounting screws securely if
the panel was drilled and tapped. Discard the nuts supplied with the screws. If the panel was drilled only, then use the nuts with the screws to secure the control to the panel.
q 7. If the CBC-300-C or CBC-300-C2 was
used, insert the knob on the internal potentiometer shaft.
q 8. Attach the switch setting label next to the
control as a reference for switch set up.
Note: Be careful not to pinch or crimp the potentiometer wiring to prevent shorting to the chassis or control components.
This completes the mounting of the control. The unit is now ready for final wiring. Refer to the wiring section for final wiring.

System Troubleshooting
A. Symptom: Green LED indicator marked “Power” does not come on when power is applied to the CBC-200 Controller.
Probable Cause Solution
No Power is applied to the Control • Check that AC power is applied to the control.
• Incorrect wiring on AC power to the control.
• Check for 120 VAC at Terminals 2 and 3 with an AC Voltmeter.
Optional line fuse is blown • Check for blown fuse – replace.
Indicator LED is defective • Check for 120 VAC at Terminals 2 and 3 of the control.
• Check for output voltage at output terminals for Channel 1 and Channel 2. If voltage is not present, replace control or board.
B. Symptom: Red LED marked “short” illuminates
Probable Cause Solution
Shorted magnet coil • Check resistance of magnet coil used and replace if necessary.
Wiring between control and magnet shorting • Check for shorted conditions in wiring between the magnets and
the control, and wiring to chassis ground.
Improper magnet coil voltage • Check magnet for proper coil voltage rating.
Transient noise • Check for source of transient noise and suppress. Wire control
using shielded cables. Segregate wiring runs.
C. Symptom: Magnets do not engage when power is applied.
Probable Cause Solution
External switching improperly wired • Check wiring and switch connections and rewire if necessary.
Torque adjust set to zero (0) • Set torque adjustment potentiometer to maximum level.
Current range switch improperly set • Check DIP Switch settings per chart and reset if required.
No power applied to the control • Refer to Symptom A above.
System incorrectly wired • Check wiring per the wiring diagram and rewire if necessary.
Fail safe brake used in place • Check to insure that a fail safe brake is not being used in place of of power applied brake a power applied brake. Replace brake with correct brake.
D. Symptom: Magnets do not disengage when power is removed
Probable Cause Solution
External switches incorrectly wired • Check wiring of switching circuits and rewire if necessary.
Fail safe brake magnet being used • Check to see if fail safe brake is being used in place of power
applied brake.
Faulty control • Replace control and see if problem is resolved.
E. Symptom: Magnets do not appear to have enough torque
Probable Cause Solution
DIP Switch improperly set • Check DIP switch setting per chart and reset if necessary.
Magnets incorrectly wired • Check wiring between control and magnets and rewire if required.
Torque adjust potentiometer set too low • Check setting of torque adjust potentiometer and set to maximum
if required.
Magnets are incorrectly sized • Verify sizing is correct by repeating selection process.
