SBS System – SB-1000 Operation
Trouble Shooting Guide
This guide is designed to help you if you experience problems with your SBS Balance System.
If the Power-On screen appears during an Auto Balance operation, the power supply to the SB-1000 is likely
below the required amperage specification.
Step 1
ERROR MESSAGES. If the balance Control Unit is displaying any error messages, refer to the
Error Indications section of this manual for explanation of the message(s) displayed. Contact Accretech SBS,
Inc. for assistance as required.
If reporting a service issue, please indicate the Error Code (letter) of any
displayed Errors.
Step 2
VIBRATION SENSOR. If no error messages are displayed, check the Vibration Sensor. Verify
that the Sensor is firmly seated on the machine, its magnet firmly tightened in place, and it is properly
connected to the Control Unit. Also check that the Sensor's position on the grinding machine accurately
reflects machine balance
(see: Vibration Sensor Location section)
.
As a final check, set the RPM manually on the Control Unit to the operating speed of the grinder, and verify
that there is an incoming vibration signal. To perform this Test the SB-1000 must be set to Automatic
Balance mode, and then press the button to set the RPM. If you receive a near zero reading from the
Sensor after manually setting the RPM, the Vibration Sensor and Control Unit should be returned for repair.
Contact Accretech SBS, Inc. for a return materials authorization (RMA) number.
Step 3
BALANCER (Automatic Balance mode only). If the Vibration Sensor is working correctly, the
next step is to perform an integrity check of the rest of the system. This test should be performed with the
machine running, but not during a grinding or dressing cycle. Press the MAN. button to enter the manual
control mode, and simply press each of the four manual buttons, one at a time, for a period of about 5
seconds. With each movement of the Balancer weights, the SB-1000 should register a change in the
displayed vibration level on the Control Unit. If this does not happen for any of the four buttons, there is a
service problem with the system. The Balancer, SB-1000, Vibration Sensor, and Balancer Cable should all
be returned as a unit. Contact Accretech SBS, Inc. for a return materials authorization (RMA) number.
Step 4
If the control unit’s self-check shows no service problem with the SB-1000, then investigate
environmental/application issues. The background vibration level on the machine should be monitored under
operation, and the Balance Limit setting checked against this level.
(see: Environmental Considerations
section)
The sizing of the Balancer to the application should also be checked.
(see: Verifying Balancer
Sizing section)
If you continue to have problems after following these four steps, contact Accretech SBS, Inc. or
your SBS Balance System source for assistance.
