The method includes configuring the fixed part of the control module to be attached to a pressure supply line for receiving a fluid under pressure; providing in the fixed part a valve manifold that houses a hydraulic activated valve; detachably attaching the removable section of the control module to the fixed part; fluidly connecting an electrically activated valve of the removable section to the hydraulic activated valve such that the electrically activated valve controls the hydraulic activated valve; and configuring the electrically activated valve to electrically connect to a control section. ## Claims ### Claim 1 A method for assembling a control module having a fixed part and a removable section, the method comprising: configuring the fixed part of the control module to be attached to a pressure supply line for receiving a fluid under pressure;
