Abstract

Arrangement comprises a control block arranged between a hydraulic pump and a cylinder. The control block has channels for hydraulic lines and electrically controlled hydraulic valves that have sensors for monitoring their positions. To guarantee hydraulic safety an electrical circuit arrangement (30) is provided that supplies safety input signals (X) corresponding to an algorithm for valve setting signals (y18a, y18b, y19a) to the valves (18, 19). The electrical circuit is hard-wired to the control block.
