4.2 Pressure monitoring / switching function OUT1 changes its switching state if it is above or below the set switching limits (SP1, rP1)� The following switching functions can be selected: • Hysteresis function / normally open: [OU1] = [Hno] (→ fig. 1). •...
4.3 Pressure monitoring / analogue function The analogue output can be configured� • [OU2] defines whether the set measuring range is provided as 4���20 mA ([OU2] = [I]) or as 20���4 mA ([OU2] = [InEG])� Scaling can be set by means of the teaching process or by entering a value for the ASP and AEP parameters�...
4.4 Customer-specific calibration The customer-specific calibration changes the curve of measured values compared to the real measured values (shifting / change of the gradient; (→ 9.4.6) [CAL])� • Two calibration points can be defined (CP1, CP2)� The two points are independent of each other�...
5 Installation Before installing and removing the unit: make sure that no pressure is applied to the system� Note: If 0% is displayed and no pointer is visible, this does not mean that no pressure is applied to the system! We recommend horizontal installation for high medium temperatures�...
