TIC Liner 3000 with Communicator Individual functions Description of function: No volume flow flowing, the solenoid valves are not actuated Due to the two face-end pressure springs, the spool is positioned so that port P is blocked (see diagram). The consumer port is blocked by the non-return valve (732). Solenoid coil (Y158) is active The solenoid coil (Y158) is actuated by the CCU (CLAAS Control Unit). The active solenoid coil (Y158) actuates the spool to the left against the face-end pressure spring. Volume flow flows from channel (P) via the spool, opens the non-return valve (732) and reaches the left-hand consumer port.
Solenoid coil (Y159) is active The solenoid coil (Y159) is actuated by the CCU (CLAAS Control Unit). The active solenoid coil (Y159) actuates the spool to the right against the face-end pressure spring. Volume flow flows from channel (P) via the spool to the closed consumer port. The pressure which now builds up opens the non-return valve (732) via the ram (s). The left-hand consumer port is now connected to the tank (T) via the opened non-return valve and the spool. 12/03 Lin-h-Kap2 2-11
