DRS – Pressure controller with load sensing
For description of load sensing, see page12.
Notes
▶ For versions with controller DRS, a drain line is
needed from port T
1
to the reservoir.
▶ The pressure controller overrides the load-sensing
controller, i.e. the load-sensing function operates
below the set pressure.
