5 2 Control Unit TECHNICAL DOCUMENTATION For the PS-500 are different Control Units available Manual Control Unit, P/N Pneumatic Control Unit, P/N Electrical Control Unit, P/N These Control Units are delivered with separate technical documentations. 2.1 Electrical Control Unit Connection: Connection P (Pressure) and T (Tank) are connected with hydraulic power unit. Connection D is connected to air supply. Connection A, B, C and D are connected to the Powerslip. Connection S4 and S5 are electrical control lines (S4 = Slips up, S5 = Slips down). Connection S5 is connected also to the grease intervall counter. Connection S7 is connected to the grease interval counter. Functional Description The control unit controls the Powerslip with an electrical controlled 4/3 way valve (Pos. 5) Two safety valves (Pos.4) are installed to avoid damage on the Powerslip Between set-slip operation and raise-slip operation the 4/3 way valve has to stay in middle position by de-energizing the solenoids at least for a short moment. Otherwise the hydraulic pressure is not able to release. This causes problems with the feedback signal. A time limit relay has to be installed in both control lines, if there is no central position provided by the electric control for the 4/3 way valve (Pos.5). Ball valves on connections P and T allow depressurised connection and disconnection of hydraulic hoses (Pos. 6). The return line C is set under pressure from the Powerslip (Feedback signal), if the slip is set or raised completely. Only one line A or B in the control unit is under pressure, depending on slip is set or raised. With help of the 3/2 way valve between signals S6 and S3 the slip position is differentiated (S3 = Slips are set, S6 = Slips are raised). The optional available grease intervall counter counts the actuations of the slip. After a predefined number of actuations (adjustable) the grease intervall counter gives a signal to connection S7 of the control unit. The pneumatic pressure to the grease pump is activated through the 2/2 way valve. The Powerslip is greased. 5
