SBS System – SB-1000 Operation
Manual Balance Overview
Important
- Performing a Manual Balance will only be successful if the user is very careful in following
each step of the process, and making certain that weight movements and additions are performed accurately.
Both the mass of weight used and the positioning of weights used will determine the accuracy of the Balance
achieved.
Press
Balance to start a complete Manual Balance operation. There are three phases for each balancing
cycle:
Zero
phase. The vibration level is measured and saved.
Test
phase. The test weight is measured so its effect can be calculated.
Solution
phase. The balancing solution is given. The
Trim
phase is just an iteration of the Solution
Phase, performed if more adjustment is needed.
Four Parts of Each Phase:
1.
Stop spindle. The control indicates that the spindle needs to stop.
2.
Apply weights. Once stopped the operator must adjust the weights.
3.
Start Spindle. The spindle must be started.
4.
Measure. The vibration can be measured for calculating the next phase.
Information is not remembered through a power cycle. The hardwire interface output relays will remain
active during the balance operation. Except where noted, the
Cancel button will stop the balance
operation and return to the main screen.
Trim Phase
The first two phases of the balance cycle (Zero and Test) allow the SB-1000 to determine and save essential
information regarding the condition of the grinder and how changes in balance weights will effect machine
balance. Assuming the conditions on the machine do not change (RPM, wheel size, etc.) then subsequent
balance operations can be successfully performed without re-running these two phases. If machine
conditions do change, then performing balance operations based on the saved results of the Zero and Test
phases will produce inaccurate results.
Trim phase balancing can be performed at any time that vibration levels rise above a satisfactory balance
condition. Press Manual to start a Trim Balance operation. This skips the Zero and Test phases of the
operation and starts at the Solution phase. To do this the SB-1000 must have saved results from a previously
completed Zero phase and Test phase. If the Manual button is pressed when these two phases have not
been completed, then the
FPI indication will display for 1.5 second, and the Solutions screen will not be
displayed.
Balancing Problems -
If successive Trim balance attempts are unsuccessful, this is an indication that either
machine conditions have changed, or an error has occurred in weight placement (inaccurate position(s) or
mass changes). In this case the operator should verify the Scale Direction setting is still accurate, then press
to start a new complete Manual Balance operation.
Three sections follow to describe the operation of the different balancing types.
