Operating Manual ILM-4 Application / Intended use • Inductive measurement of specific conductivity and concentration of fluid media in the range of 0…1000 mS / cm • For use in hygienic applications of the food, beverage, and pharmaceutical industries • Not suitable for use in explosive atmospheres •...
Operating Manual ILM-4 Special features / advantages • The sensor structure is based on a modular device platform which can be tailored to re- quirements and is easy to exchange if faulty • Wear-free, inductive measurement procedure • In contrast to conductive measurement procedures, there are no problems due to elec- trode deterioration or polarization.
Operating Manual ILM-4 Requirements for hygienic installation Conditions for hygienic installation according 3A and EHEDG • The ILM-4 / ITM-4R is designed for CIP/SIP cleaning. The sensor can withstand a maximum of 150 °C / 60 min. • The mounting position must guarantee self-draining properties.

Operating Manual ILM-4 Not permitted mounting positions Installation from top or from bottom should be avoided. This can lead to incorrect measurement due to accumulation of air or deposits. Disregarded flow direction The device should be aligned so that the "FLOW" label on the bottom of the de- vice in the direction of flow.

Operating Manual ILM-4 Concentration: Two predefined ranges for common CIP media (NaOH or HNO3) are available for se- lection. In addition, there is the possibility of entering up to 8 customized media specific points (each for conductivity and concentration). A self-defined range is entered by specifying at least 2 points with values >...
Operating Manual ILM-4 Electronics (Signaling interface): • Signal selection for the 4…20 mA signal: Selection between conductivity 1 or 2, concentration and temperature • Set value for 4 or 20 mA signal: By default, the lower range limit is used for the 4 mA signal and the upper range limit for the 20 mA signal.

Operating Manual ILM-4 Settings using the User Interface The software structure of the User Interface is like the structure of the PC version. The system is operated using two control buttons to the left and right of the display. These two buttons can be used to navigate through the tree structure of the User Interface to change param- eters.

Operating Manual ILM-4 Installation of the „Large User Interface“ (LUI) Remove the plastic cover (continue with step 4), or remove the puck with the mounted small display (continue with step 2) Remove the small display Install the puck in the sensor head Mount large display Hot-plug function: The large display can be installed while the sensor is energized, but this re- quires the usual precautionary measures when working with electronic components.
Operating Manual ILM-4 7.2 Retrofitting the display if a small display (SUI) was already installed First the puck with the mounted display needs to be removed using the puck puller tool (Fig. 4). To do so, detach the wires from the cable terminal. Then insert the five arms of the puck puller in the plastic tabs of the puck (Fig.
Operating Manual ILM-4 Dimensions For all process connections, the conductivity sensor can be ordered with a submersion length of L20 (20 mm) or L50 (50 mm).

Operating Manual ILM-4 Repair and maintenance The conductivity sensor described here is maintenance-free. However, if it should become nec- essary to calibrate the sensor, the offset (zero point) and the span of the sensor can be set in the "Calibration " mode (via the software). For this purpose, navigate to the following window via the user interface (for example, for con- ductivity 1): "Conductivity Measurement →...
