Warner Electric CBC-450 - Manual (Page 50)

Start up & Initial Check-Out
Start-up and check-out of the CBC-400/CBC-450 series of clutch/brake controls should be straight
forward and simple if proper hook-up and connections were made per appropriate installation
procedures.
Initial check-out can be accomplished statically without having the motor driving the system energized.
Checks will be made to insure proper switching and output operation of the clutch/brake, clutches or
brakes based on the operating mode and type of switching employed.
Refer to the following logic diagrams for proper switching and output functions based on various modes:
Alternate Mode, Three-Wire, Sinking................................Figures 13b thru 16b
Simultaneous Mode, Three-Wire, Sinking ........................Figures 13c thru 16c
Alternate Mode, Two-Wire, Sinking ..................................Figures 17b thru 20b
Simultaneous Mode, Two-Wire, Sinking ..........................Figures 17c thru 20c
Alternate Mode, Three-Wire, Sourcing ............................Figures 21b thru 24b
Simultaneous Mode, Three-Wire, Sourcing......................Figures 21c thru 24c
Alternate Mode, Two-Wire, Sourcing................................Figures 25b thru 28b
Simultaneous Mode, Two-Wire, Sourcing ........................Figures 25c thru 28c
1. Apply AC power to the control. Check that
proper outputs are activate based on
operating modes and appropriate logic
diagrams.
2. With the drive components still off-line,
activate the appropriate inputs and
determine that control switches output
channels accordingly. Refer to the
appropriate timing diagrams.
3. If using three-wire switching mode,
alternate switching inputs and ensure
outputs follow proper switching signals.
4. If Channel 2 override switching is used,
switch control using normal switching
inputs so that Channel 2 output is on
(alternate mode) and switch Channel 2
override input. Insure Channel 1 output
comes on when this occurs. If
simultaneous mode is used, both
output channels should switch off.
5. If all switching functions and output functions
operate correctly, system is ready for normal
operation. If problems are encountered or
system does not switch properly, refer to
hook-up and troubleshooting sections of this
manual. If this fails to correct the problem,
contact your local Warner Electric
Representative or the Technical Support
Department at 1-800-825-9050 for further
assistance.
6. This completes the preliminary check-out and
start-up of your control. Turn off power and
secure any enclosure or panel being used.
The system is now ready to run.
