Troubleshooting

For Bulletin 150 SMC   Smart Motor Controller technical support on
start-up or existing installations, contact your Allen-Bradley representative.
In the United States you can also call 1-800-765-SMCS (765-7627) for
assistance during the hours of 8:00 am to 12:00 noon and 1:00 pm to 4:30
pm (Central Time Zone) from Monday through Friday.

For safety of maintenance personnel as well as others who might be exposed to
electrical hazards associated with maintenance activities, the safety related work
practices of NFPA 70E, Part II, should always be followed when working on
electrical equipment.  Maintenance personnel must be trained in the safety practices,
procedures, and requirements that pertain to their respective job assignments.

WARNING: 

 To avoid shock hazard, disconnect main power before

working on the controller, motor, or control devices such as Start/Stop
push buttons.  Procedures which require parts of the equipment to be
energized during troubleshooting, testing, etc., must be performed by
properly qualified personnel, using appropriate work practices and
precautionary measures as specified in NFPA 70E, Part II.

!

CAUTION: 

 Disconnect the controller from the motor before

measuring insulation resistance (IR) of the motor windings.  Voltages
used for insulation resistance testing can cause failure of SCRs.  Do not
make any measurements on the controller with an IR tester (megger).

!

NOTE:

  The time it takes for the motor to come up to speed may be less than  the

Start Time setting and will vary depending on the frictional load and
inertial characteristics of the system.

NOTE:

  Depending on the application, the SMB Smart Motor Braking, Accu-Stop,

and Slow Speed with Braking options may cause some vibration or noise
during the stopping cycle and this may be minimized by lowering the
braking current.  If this is a concern in your application, consult the factory
prior to applying these options.
