PULSTRONIC
PROPORTIONAL GAIN (potentiometer P5)
The gain can be adjusted in a range between 5 and 50 with potentiometer P5.
The proportional gain is factory-adjusted to its maximum (50).
The proportional gain can be adjusted to reduce oscillations and overshoot:
• To increase the gain, turn P5 clockwise.
• To decrease the gain, turn P5 counterclockwise.
There are 14 turns between the maximum value and the minimum value (there is no limit stop).
OPTION : PRESSURE SWITCH
The PULSTRONIC valve is also available with a PNP pressure switch (option no. 2: 6 t h d i g i t i n t h e o r d e r c o d e ) .

: Window size of pressure switch
This window size can be adjusted between ±2,5 % and ±10 % at maximum with potentiometer P6.
The maximum output current at pin 4 is 500 mA at 24 V DC.
Pressure switch adjustment
1 - Connect the PULSTRONIC (see chapters on pneumatic and electrical connection).
Do not yet apply pressure to the valve.
2 - Turn potentiometer P6 clockwise to its maximum value. There are 14 turns between the maximum value and the minimum value
( t h e r e i s n o l i m i t s t o p ) .
3 - Connect a LED with a resistance of 4.7 KΩ i n s e r i e s
between pin 4 and GND.
4 - Apply a setpoint equivalent to half of the desired total window size (without supplying pressure to the valve).
Example: If you need a pressure switch window size of ±300 mbar for a PULSTRONIC of 0 - 3 bar, a setpoint of 1 volt (10 %) is
required (0.3 bar = approx. 10 % of 10 volts).
5 - Turn potentiometer P6 counterclockwise until the LED status is changed.
