Abstract

A method is provided for controlling auto-cycling of a hydraulic torque wrench system (1). The method comprises: setting a target pressure (Pmax) for a tightening; receiving a signal indicative of said hydraulic pressure; and detecting if any one of certain conditions a)-c) occurs during a trial cycle (TCO) performed as an initial cycle of the tightening. The method further comprises: in response to detecting condition a) or c), estimating an exit pressure of the performed trial cycle and continue the tightening by further auto-cycling; and/or in response to detecting condition b), commanding termination of the tightening. With the present method, an estimation of which state the joint is in at the beginning of the tightening is provided and action may be taken accordingly.
