For the switching position shown in Figure 3, it has been
assumed that the solenoid 1 is energized and the
solenoid 2 deenergized.
The energization of the solenoid 1 causes the solenoid
armature 3 to be drawn against the spring 5 into the position
shown; the duct 17 is closed, and the duct 7 is
opened. This causes the upper side of piston 14 to be
pressurized via the ducts 16, 7 and 21. The piston 14
and 12 accordingly move into the position shown. The
duct 21 is linked to P, pressure build-up to A is prevented
by the piston 13. The duct 23 is exhausted via duct 20 to
A or R. There is thus no possibility of pressurizing

The valves therefore monitor themselves during each
switching operation.
If the leak at the seal of duct 20 is larger than can be
compensated by the clearance between the piston 12 and
the body 11, the duct 8 is exhausted. The result is the
same as described under the heading "Malfunction".
If faulty switching takes place, the start procedure must
be repeated, i.e., the two-hand safety valve must be
released and re-actuated.
