3.1 Switching function OUT1 changes its switching status if it is above or below the set switching limits� Hysteresis or window function can be selected� Hysteresis function Window function T = Temperature T = Temperature SP1 = set point FH1 = upper limit value rP1 = reset point FL1 = lower limit value HY = hysteresis...
3.2 Analogue function • The unit converts the measured signal into a temperature-proportional ana- logue signal� Depending on the parameter setting the output signal is at: 4���20 mA [ou2] = I 20���4 mA [ou2] = I 0���10 V [ou2] = U 10���0 V [ou2] = U •...
In case of internal fault, the output signal behaves according to the parameter set in [FOU2]: [FOU2] = On [FOU2] = OFF [ou2] = I 21 mA 3�5 mA [ou2] = I 3�5 mA 21 mA 3.2.2 Voltage output Maximum measuring range at [ou2] = U Measuring range scaled at [ou2] = U U [V] U [V]...
3.3 Display colour change The colour of the characters in the display can be set via the parameter [colr]� With the parameters rED (red) and GrEn (green), the display is permanently set to one colour� Via further parameters, the colour of the characters changes according to the measured value: OUT1 OUT1 and OUT2...
3.3.2 Parameter r-cF, G-cF Colour change if the measured value is within definable limits� 3.4 IO-Link 3.4.1 General information This unit has an IO-Link communication interface which requires an IO-Link-capa- ble module (IO-Link master) for operation� The IO-Link interface enables direct access to the process and diagnostic data and provides the possibility to set the parameters of the unit during operation�...
