9.3.4 Control valve "simultaneous operation"
Two levers are tted on this valve. Each lever is assigned to one pressure port. The pressure
application of the relevant pressure hose is controlled by turning the relevant lever.
There are 2 switching stages for each lever:
0 = circulation at static pressure (no pressure supplied to the hydraulic hose)
1 = pressure supply to the pressure hose
9.3.5 Controlvalve"triple-owoperation"
Three levers are tted on this valve. Each lever is assigned to one pressure port. The pressure
application of the relevant pressure hose is controlled by turning the relevant lever.
There are 2 switching stages for each lever:
0 = circulation at static pressure (no pressure supplied to the hydraulic hose)
1 = pressure supply to the pressure hose
Case 3: Two hose pairs and one rescue device are connected (at connection A):
If two hose pairs are connected and there is only one rescue device at the hose pair of
connection "A", the following instructions are important:
1. The control lever for switch positions must be in position "A".
2. The hydraulic uid supply of the connected rescue equipment and switching to circulation
at static pressure take place by switching the control lever for the outlet valve. ("1" = uid
supply; "0" = circulation at static pressure)
Case 4: Two hose pairs (with quick-disconnect couplings) and one rescue device are
connected (at connection B):
If two hose pairs are connected and a rescue device is only connected at the hose pair of
connection "B", the device works neither in switch position "A" nor in switch position "A+B".
The second hose pair at connection A without a connected rescue device indicates to the
valve that a device is connected at connection A that has to be supplied with maximum
operating pressure. This switches off connection B, which is no longer supplied with hydraulic
uid.
To exclude this possibility, you should either connect a second rescue device or join the
supply and return hoses of the connection that is not used (short-circuiting).
Case 5: Two hose pairs (with mono-couplings) and one rescue device connected (at
connection B):
If two hose pairs are connected and a rescue device is only connected at the hose pair
of connection "B", the device only works in switch position "A+B". This is made possible
by the female mono-coupling halve, which enables an internal uid circulation when not
connected.
