  SBS System – SB-1000 Operation   

Automatic Balance Operation 

From the Main screen press the 

 Balance button to start an Auto-Balance cycle.  This screen displays for 

the duration of the balance cycle, showing the 

 symbol in the status area of the screen (below the RPM 

indication).  The Balance cycle can also be started or terminated from the hardwire inputs.  A Balance cycle 
may be run with an accurate Manual RPM value entered if there is no incoming RPM signal.   

The 

 symbol will rock back and forth during the balance cycle to indicate activity, and the   Weight 

indicators will show + / - to show weight activity and direction.  The balance cycle continues until the Limit 
setting is reached, or the cycles fails and times out. 

Press 

Cancel to end the balance cycle at any time.  Upon completion or termination the display returns to 

the Main screen. 

 
Manual Weight Movement - Automatic Balance Mode 

The SB-1000 in Automatic Balance also allows the weights in the SBS Balancer to be operated manually.  
The  ability  to  move  the  balance  weights  is  useful  for  performing  diagnostic  tests  and  allows  operators  to 
manually balance machines where needed.  From the Main screen press the   Manual button to display the 
Manual Weight Movement screen, showing the   symbol in the status area of the screen. 

 

If an incoming RPM signal is not detected, then this screen will 
request a “Manual RPM” value be entered.  The RPM value is 
changed using the arrow keys. 

Press 

 Manual, 

 Setup,  or 

 Cancel  to  go  on  to  balance 

mode (

 Cancel will not save the new RPM). 

The Manual RPM value will be used until an actual RPM signal 
is detected, which will then replace it. 

 

The Manual Weight Movement screen can be used to move the weights in a balancer. 

The 

buttons will move one of the balancer weights in the indicated direction.  The 

buttons will 

move  the  other  balancer  weight  in  the  indicated  direction.    Pressing  a  button  will  cause  a  30  ms  motion 
followed  by  a  short  pause,  and  then  the  weight  will  move  continuously  until  the  button  is  released.    The 
displayed arrow will fill in to show weight activity.  Only one weight can be moved at a time. 

 Cancel  will  exit  setup  mode  and  return  to  the  Main  screen, 

 Setup  will  go  to  Setup  Mode,  and 

Balance will start an auto balance cycle.
