ZERO POINT ADJUSTMENT (potentiometer P4)
Example 1
: At a setpoint of 1 volt, the output pressure should be 3 bar: Apply a setpoint of 1 volt and turn potentiometer P4 clockwise
until 3 bar are reached.
Example 2
: At a setpoint of 2 volts, the output pressure should be 0 bar: Apply a setpoint of 2 volts and turn potentiometer P4
counterclockwise until 0 bar is obtained.
In order to avoid damaging the pressure sensor,
the supply pressure must always be less than the maximum input pressure
defined above

SPAN ADJUSTMENT (potentiometer P3)
Example for a valve adjustment with a maximum output pressure of 6 bar.
At a setpoint of 0 - 10 Volts the output pressure should be 0 to 5 bar:
Apply a setpoint of 10 Volts and turn potentiometer P3 counterclockwise until 5 bar are reached at the valve output.
Turn potentiometer counterclockwise.
Turn potentiometer clockwise.
The span can be adjusted between 75 and 100 % of the maximum output pressure.
The factory setting is 100 %.
