positioners with filtered oil.
Dump valve 1

• To prevent high pressure and thereby unnec-
essary heating of the oil there is an automatic
dumping function. When no lever movement
has been made for 3 seconds SPACE system
opens the dump valve and the oil is returned
directly to the hydraulic tank. As soon as the
operator moves a lever the valve closes.
Dump valve 2
[cranes with base controls]
• Allows operation of the stabiliser extensions
and legs only when this valve is activated.
The dump valve 2 will be placed between the
main control valve and the stabiliser control
valve. The dump valve 2 must be activated
from the SPACE interface before the stabilis-
er system can be controlled.
