Страница: 20 / 120

To adjust the second sensor, the process valve must be moved once to its end
positions by an external solenoid valve.
3.2.3 Control Top with Solenoid Valves
The control top with solenoid valves acts as a control top. The signalling takes
place in the same way as with the control top without solenoid valves. with the
difference being that the solenoid valve integrated in the base is operated in
accordance with the control signals. Depending on the design of the process
valve, up to 3 solenoid valves can be installed in the control top.
To provide compressed air support to the actuator spring, a pneumatic NOT logic
element can be used.
The control signals are given by the user's process control system or by
operating the solenoid valves manually. To do this, use a screwdriver to turn the
screw (S) from 0 to 1, see figure.
