The control signals are given by the user's process control system or by the
microprocessor in the control top during automatic end position programming.
In manual mode, the main actuator can be controlled using the buttons in the cap
in order to move the process valve to its end positions or by operating the
solenoid valves manually. To do this, use a screwdriver to turn the screw (S) from
0 to 1, see figure.
