Two-section switchboard external hydraulic circuit controlling levers function

Lever (a) function
N -Neutral position. Outlets to a quick-coupler (1) and (2)
are closed and oil in the connected hydraulic device is
locked. Lever (a) is locked in this position.
1 - Pressure in quick-coupler (1). Quick-coupler (2) is
connected with waste. After release, lever returns to
position (N).
2 - Pressure in quick-coupler (2). Quick-coupler (1) is
connected with waste. After release, lever returns to
position (N).
P -Floating position. Both quick-couplers (1) a (2) are
connected with waste and oil can freely flow in them in
both directions. Lever (a) is locked in this position.
Lever (b) function
N -Neutral position. Outlets to quick-couplers (3) and (4)
are locked and the oil in the connected hydraulic device
is blocked. Lever (b) is locked in this position.
3 - Pressure in quick-coupler (3). Quick-coupler (4) is
connected with waste. After release, lever returns to
position (N).
4 - Pressure in quick-coupler (4). Quick-coupler (3) is
connected with waste. After release, lever returns to
position (N).
Quick-coupler (0) is directly connected with the area of
final house driving and is designed for returned oil from
external hydraulic devices (e.g. from rotation hydro
engines etc.).
