Important note Non-compliance can result in malfunction or interference. Information Supplementary note. 1.2 Warning signs used CAUTION Warning of personal injury. Slight reversible injuries may result. 2 Safety instructions • The device described is a subcomponent for integration into a system. - The manufacturer is responsible for the safety of the system.
CAUTION For medium temperatures above 50 °C (122 °F) some parts of the housing can heat up to over 65 °C (149 °F). Risk of burns. ► In this case do not touch the unit. ► Protect the housing against contact with flammable substances and uninten- tional contact.
4.1 Switching output OUTx changes its switching status if it is above or below the set switching limits (flow or temperature). Hysteresis or window function can be selected. Example of volumetric flow monitoring: Hysteresis function Window function SP = set point SP = upper limit rP = reset point rP = lower limit...
4.2 Frequency output The unit provides a frequency signal that is proportional to the volumetric flow quantity and the medium temperature. Up to the limit value set under [FEPx] (for OUT2 = TEMP: between the limit values set under [FSP2] and [FEP2]) the frequency signal is between 0 Hz and the fre- quency value set under [FrP 130 % 120 %...

8.1.1 Explanation main menu Switching output with hysteresis function Set point 1 = upper limit value at which OUT1 switches. Reset point 1 = lower limit value at which OUT1 switches off. Set point 2 = upper limit value at which OUT2 switches. Reset point 2 = lower limit value at which OUT2 switches off.

9 Parameter setting Parameters can be set before installation and set-up of the unit or during opera- tion. If you change parameters during operation, this will influence the function of the plant. ► Ensure that there will be no malfunctions in your plant. During parameter setting the unit remains in the operating mode.
Display Type Description [UL] Warning Below the detection zone: Measured value lower than -20 % of the final value of the measuring range. [OL] Warning Detection zone exceeded: Measured value greater than 120 % of the final value of the measuring range. [SC1] Warning Switching status LED for OUT1 flashing: OUT1 short circuit.
