TIC Liner 3000 with Communicator Overall Hydraulic System Connection to tractors with load-sensing system and a Power Beyond port The quick release coupling 801-2 is connected directly to the pump via the Power Beyond port P. The quick release coupling 801-3 is connected to port T (pressureless return line) of the tractor. The quick release coupling 801-4 (LS, working hydraulics signal) is connected to the tractor's "LS signal" port when using this connection option. The system screw (handwheel) 634 is turned in up to the stop so that the input pressure balance 763 is blocked. The tractor's hydraulic pump regulates as a function of the attachment's load signal.
Test points/Characteristics When no function is active on the attachment, the attachment must not load the tractor hydraulically (The tractor engine speed must not be reduced). The allowed temperature of the tractor's hydraulic system must not be exceeded; see also the Operator's Manual of the tractor. Important! The pressure relief valve 706 must be set approx. 20 bar higher than the tractor's pressure protection (oil will heat up!). Block pressure relief valve 706 if necessary. 12/03 Lin-h-Kap1 1-13
