<p>The system has valves (3a, 3b, 4a, 4b) regulating volume flow of a pressure medium and arranged in a pressure line system of a control valve arrangement (16). The valves are electrically controllable by an electronic control and regulation unit (5). The valves are formed in such a manner that an actual adjusted operating condition i.e. disengaged or engaged operating condition, of a clutch (2) is achieved during power supply failure and loss of the control of the valves by the electronic control and regulation unit.</p> |
