WIRING DIAGRAM FOR RECTILINEAR HYDRAULIC MOTOR'S ELECTRO-HYDRAULIC SWITCHBOARD CONTROL CIRCUIT

摘要

The invention concerns a circuit for controlling the connection of a linear hydromotor electrohydraulic switchboard fitting to be used primarily in equipment for centring cut-outs before the veneer peeling machine. The fundamental part of this solution is the fact that a photo-sensing unit (6) as well as an incremental sensor (3) are connected to inputs of an electronic change-over switch (12) one output of which is connected to a reverse reader (14) directly and the other output through a veneer parting machine (13) into two parts. Each reader (sensor) (14) is connected through an amplifier (15) to the input of the controlled electrohydraulic switchboard (16).<IMAGE>
