    Life time recommendations Linde high pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using high-quality hydraulic fluid.

  • Page 9: Linde Lsc-System

    Linde LSC-System. The Linde Synchron Control System (LSC-System) for open loop hydraulic circuits enables demand-orientated pump volume control based on load sensing technology (LS technology). A LSC-System compensates the effect of varying loads, varying numbers of actuators and different load levels at different actuators. This happens automatically, thereby making machine operation more convenient since, unlike in other systems, continuous corrective action is no longer required.

  • Page 20: Controllers

    All controllers equipped with load sensing function are fully compatible with the Linde Synchron Control System (see section <<Linde LSC-System>>).

  • Page 21: Ls. Load Sensing

    Controllers. LS. Load Sensing Linde pumps with load sensing control enable the movement speed required of the selected actuator, e.g. of a boom, to be spe- cified via the valve opening. The measured pump and load pressures are continuously balanced by the load sensing controller of the hydraulic pump.

  • Page 22: Lp. Ls With Hydraulic Pressure Cut-Off

    Controllers. LP. Load Sensing with hydraulic pressure cut-off In addition to the load sensing function the LP-controller offers maximum pressure limitation. Once the system pressure reaches the set pressure of the pressure cut-off valve, the LS-controller is overridden and the pump swashes back, whilst maintaining the system’s regulating pressure.

  • Page 23: E1L/H1L. Ls With Electric/Hydraulic Override

    Controllers. E1L/H1L. Load Sensing with electric / hydraulic override In addition to the load sensing function, HPR-02 pumps with H1L or E1L controllers offer the possibility of overriding the ∆p LS-signal hydraulically or electrically. This enables a so called mode control for selecting different operating points or enables a power limit regulation (underspeed control).

  • Page 24: E1L. Ls With Electric Override

    Controllers. E1L. Load Sensing with electric override In addition to the load sensing function, the HPR-02 E1L offers an electric override for mode selection and power limit regulation (underspeed control). The integration of all functions in the pump controller enables direct signal transfer without delays. The controller-specific data are independent of the nominal pump size.

  • Page 25: H1L. Ls With Hydraulic Override

    Controllers. H1L. Load Sensing with hydraulic override In addition to the load sensing function, HPR-02 pumps with H1L-controller offer the possibility of overriding the ∆p LS-signal hydraulically. This enables either a so called mode control for selecting different operation points or establish a power limit regula- tion (underspeed control).

  • Page 27: Pump Controllers With Position Feedback

    Pump controllers with position feedback TL2-, LEP- and ETP-controllers offer a feedback of the swashplate position. Therefore they are – unlike LP-, E1L- and H1L-controllers – not mounted on the valve plate housing, but on the pump housing. Besides their individual characteristics, these controllers have some similar features.
  • Page 28 Pump controllers with position feedback T-Axis (TL2/ETP): hydraulic movement of the regulation begin Controllers of the TL2 and ETP type offer a power limitation with a hyperbolical characteristic. The controller is set ex works to a customer specific power limit value. The volume flow is restricted, when this limit is exceeded. By means of control ports at the controller, the point at which the power limiter sets in can be raised, as well as lowered during operation.

  • Page 29: Tl2. Ls With Hyperbolic Power Limitation

    Controllers. TL2. Load Sensing with hyperbolic power limitation The control principle with power limitation is used to optimize power utilization of the prime mover in applications where less than the full power capacity is available for the hydraulic system. In addition to the load sensing function the HPR-02 TL2 offers hyperbolic power limitation.

  • Page 30: Limitation And Pressure Cut-Off

    Controllers. LEP. Load Sensing with electro-proportional flow limitation and pressure cut-off The HPR with LEP-controller offers an on-demand load sensing flow control. The actual volume flow, delivered by the pump can be restricted by an electrical signal in certain points of operation. A pressure cut-off function protects the hydraulic system from overload.

  • Page 31: Hyperbolic Power Limitation And Pressure Cut-Off

    Controllers. ETP. Electro-proportional flow setting, power limitation and pressure cut-off The HPR with ETP-controller delivers a volume flow which is exactly proportional to the electric control signal. Superposed, the controller offers a hyperbolic power limitation, which optimally exploits the power of the prime mover and also protects it from overload.
