V5422L / V5422E ACTUATED BUTTERFLY VALVES
EN0B-0319GE51 R0104 4
Modulating Control (V5422E)
The V5422E series is equipped with a printed circuit board
(see Fig. 4). This board (together with a feedback potentio-
meter) is situated under the cover, where the angle indicator
is likewise located. To access the printed circuit board,
remove the cover.

Microswitch Positions
Fig. 5 shows the settings of the microswitches located on the
printed circuit board (see Fig. 4) at delivery-time.

Microswitches 1, 2, 3, and 4 are used to set the input signal
range (0/2...10 V or 0/4...20 mA) and the corresponding
output signal (see Table 2).

Terminals for Input/Output Signals
An external modulating controller controls the actuator of the
V5422E by means of an analog signal provided at terminal
70/71. An analog output signal for position indication is
provided at terminal 71/72.
Adjusting the Input/Output Signal Offset
The offset of modulating actuators is adjusted at the factory
and should not be changed. If you wish to change the offset
(using offset potentiometer P2; see Fig. 4), note that a
excessively small offset will result in oscillation of the
actuator.
Reversing Rotation Direction
In the case of the V5422E, it is possible to reverse the
direction of rotation of the valve by adjusting the feedback
signals. The feedback signals are adjusted by resetting the
microswitches and replugging the feedback potentiometer's
cables. To do this, proceed as follows:
1. Turn the power off.
2. Reset the microswitches as shown in Table 2, but with
microswitch 7 in position B.
3. Replug the feedback potentiometer's cables as shown in
Fig. 6.

4. Apply the desired control signal (10 V or 20 mA, as the
case may be) for the closing position.
5. Turn the power back on.
6. Using a small screwdriver, adjust the potentiometer P1
(located on the printed circuit board; see Fig. 4) until the
valve closes completely.
Valve Mounting
Install the actuated valve in the pipe according the following
steps (see also Fig. 7).
1. Spread the valve's flanges to facilitate installation. The
valve's disc must be partially open.
2. Set all stay-bolts while keeping the valve's disc slightly
open and without tightening the nuts.
3. Open the valve's disc completely. Ensure that the piping
is aligned. Tighten diagonally opposite the nuts until the
flanges are in contact with the body of the valve. Never
use gaskets or grease. Never weld the flanges after the
valve has been installed.
