The tightening step is evaluated at the endof the step. The tightening step is evaluated as NOK if the tolerance limits have been violated (T ≤ TA–or/and T ≥ TA+) and otherwise as OK.This monitoring function cannot be selected as switching.Torque range[Nm]Tmax MmaxT[– M[–T[ M[ T[+ M[+Tmin MminTF:A ZF: W[o]Figure 9–25:Torque range monitoring function where T = f(A)System 350 | 3 608 878 040/05.2008
