When the 3/3 way raise front attachment solenoid valve is actuated on
the forage harvester, the Reed switch*75 connects earth to relay 15,
terminal 85 and relay 12, terminal 85.
Relay 15 cuts the current to the lock-up valve unit 109.
Relay also cuts the current to the lock-up valve units 89 and 99 (the lock-
up valve units are closed when deenergized).
When raising is complete, the mower unitsí weight generates a pressure
of > 85 bar in the cylinders of the Jaguar front attachment.
The oil pressure switch 94 connects earth to relay 12, terminal 85 as long
as the pressure in the lift cylinders is > 80 bar.
Relay 12 switches and cuts the power supply to the lock-up valve units
89, 99 and 109.
This is necessary to make the mower units remain in their position when
lifting is complete on the turning area. When the pressure in cylinders 90
and 100 rises to above 140 bar, the oil pressure switches 96 open briefly.
Earth connected to relay 12, terminal 85 drops out and the relay connects
the current supply to the lock-up valve units 89 and 99.
The lock-up valve units open and the accumulators receive oil from the
ram rod end (from the front attachment cylinders on the Jaguar) so that
there is no oil loss and no oil can flow from the system into the tank
(pressure relief valve 104).
* On the Jaguar 800, the Reed switch connects earth.
On the Jaguar 600, earth is supplied directly from the 3/3 way ÑRaiseì
solenoid valve.
