260/316 Bosch Rexroth AG | Tightening Technology 10 Working with the System10.1 Settings in the BS350Figure 10–6:Graph display with primary and redundancy transducersCarry out a tightening with the tightening program where the correction factor should be determined andcompare both of the displayed graphs. Enter a suitable zoom range and compare both graphs in detail(Fig. 10–7).Calculate the necessary Cred correction factor from the graphs:Cred=T prim. System 350-------------------------------------------------------T red. System 350Enter the correction factor for the tightening program, send the tightening program to the controller, andcarry out another tightening. Repeat this procedure until both graphs are practically identical.12 3221Figure 10–7:Enlarged section of the tightening graph(1) Maximum torque of the redundancy measurement transducer(2) Maximum torque of the primary measurement transducer(3) Difference between (1) and (2)System 350 | 3 608 878 040/05.2008
