Crouzet 81 series 8bar Pneumatic Logic Controller

Operating principle: The appearance of the "X1" pressure signal causes the valve to move. The "x" output is pressurised. This status is stored in memory until the "X0" pressure signal is received. This pressure
signal causes the valve to move in the reverse direction. The "x" output is pressurised. This status is also saved in memory.
- the "x" pressure output indicates that the information saved in memory is "X1",
- the "x" pressure output indicates that the information saved in memory is "X0".
