9. Channel 1 input invert switch SW10 selects the
Channel 1 input for normal or inverted signals.
Set the switch for the desired response when
the control is operated in the pulse mode:
• “Down” position applies voltage for control
response.
• “Up” position removes voltage from control
response.
10. If an auxiliary input sensor such as a photo-
electric scanner is used, auxiliary input switch
SW11 must be set for either Channel 1 or
Channel 2 input:
• “Up” position inputs to Channel 1
switching.
• “Down” position inputs to Channel 2
switching.
11. Double check all switch settings to insure they
are in the proper position for the desired
functions.
12. Apply power to the CBC-750 control.
The
machine must not be running during
preliminary tests.
13. Observe the front panel indicator LED’s as
follows:
• With the torque adjust potentiometers set
at minimum, the output indicators should
be “off”.
• Check to insure that Channel 1 and
Channel 2 short circuit indicator LED’s are
not illuminated.
• If short circuit lights illuminate, press reset
button on front panel to clear the short
light(s). If short LED’s illuminate again,
immediately shut off AC power and follow
the instructions in the troubleshooting
section of this manual on page 14 to
located the short circuit.
14. Slowly rotate the Channel 1 torque adjust
potentiometer CW to maximum output, noting
that the Channel 1 output LED illuminates and
gradually brightens.
15. Activate the switching device to switch from
Channel 1 to Channel 2 output.
16. Observe that the Channel 1 output should also
be off. Slowly rotate the Channel 2 torque
adjustment potentiometer CW noting that its
LED illuminates and increases in intensity as
the maximum setting is approached.
17. If input inhibit functions are used, activate the
inputs. Check to insure that input inhibit LED’s
illuminate, and that switching inputs do not
affect the output state.
18. if any of the auxiliary inputs are used, check
that indicator LED’s illuminate and control
response is proper.
19. Set the system to cycle automatically between
Channel 1 and Channel 2 outputs. Observe the
front panel indicators for proper functioning
based on actual inputs and outputs. Check that
short circuit indicators do not illuminate.
20. Start the machine and observe the control and
the machine for proper operation.
21. Set the Channel 1 and Channel 2 torque adjust
potentiometers to the desired level.
Setting the torque adjustments too
low will cause excessive clutch and brake slip
leading to excessive magnet and/or rotor wear.
22. Shut down the machine and turn off the con-
trol.
23. Latch the top board assembly to the chassis by
pushing down on the plastic locking pins.
24. Install the cover (if used) on the chassis by
sliding the two clips upward, latching the
cover in place.
This completes the installation and start-up of the
CBC-750 control system. If problems are encoun-
tered during start-up and check-out, refer to the
troubleshooting section of this manual.
if any problems can not be resolved by following
troubleshooting procedures, and the control is
properly installed and wired, contact your local
Warner Electric Market Representative or our
Applications Engineering Group at (815) 389-3771
for further assistance.
