Zero Point Adjustment; Span Adjustment - joucomatic PULSTRONIC 605 series Bedienungsanleitung

INSTALLATION
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 u n t i l 0 b a r i s o b t a i n e d .

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.
