Load-sensing control block (LS control block)
The load-sensing control block is attached to the side frame of the base frame by
means of an angle.

At the LS control block, 3 hose couplings for P (pump) and 2 hose couplings for
T (tank) are in each case provided for the connection of hose lines for diverse
set-ups and functions.
If the LS pressure is taken from port P1, the pump behaves like a pressure-
controlled pump. The regulated pump pressure is set to 50 bar using
the LS pressure relief valve.
The 3/2-way ball valve allows for the depressurized unloading of the system to
the leakage oil with simultaneous blocking to the pump.
