6Installation and Connection
6.1 Mechanical installation
Mechanical connection / installation notes
•The device must be installed such that the submersible body is fully surrounded by
the medium and no air bubbles can form in the sensor area. It therefore is advisable
to install the device in rising pipes.
•The device must be aligned such that the lettering "FLOW" is at the bottom of the
device in the direction of flow.
•Very strong vibrations can lead to false measurements (e.g. if installed near a
pump).
•Use the Negele CLEANadapt system to ensure that the measuring point functions
properly.
•When installing the device, adhere to the maximum tightening torque of 20 Nm.
•To correctly install CLEANadapt weld-in sleeves, use a suitable welding mandrel.
Follow the weld-in and installation instructions in the CLEANadapt product infor-
mation.

ILM-4 in horizontal pipe
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.
•The mounting position and gasket need to follow the actual 3A or EHEDG stand-
ards and guidelines.
•When using Tri-Clamp process connections, observe the requirements of the cur-
rent 3A and EHEDG regulations regarding installation position, process connec-
tions and approved seals.

Operating Manual ILM-4 6
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.
The ILM-4 inductive conductivity meter is set to operate without requiring special adapta-
tions. In isolated instances, some parameters may need to be adjusted. The parameterization
may be changed using the PC-based MPI-200 programming adapter or the User Interface di-
rectly on the sensor. This can be performed either directly on location or in the office in a dry
simulation.

Operating Manual ILM-4 7
The sensor is delivered with the following default settings:
Analog Output 1 (X45 on terminals 4 and 5)
conductivity 1 with measurement range 0…200 mS/cm
Analog Output 2 (X67 on terminals 6 and 7)
temperature with measurement range 0…150 °C
The parameter list accompanying the sensor contains the sensor settings for output 1 (terminals 4
and 5) under X45a and for output 2 (terminals 6 and 7) under X67.
The sensor can be parameterized either via the PC-based MPI-200 programming adapter, IO-link
or directly on the sensor using the User Interface.
The ILM-4 inductive conductivity meter features a modular design with a “tree structure”, which
can be tailored to meet requirements and can be easily exchanged in the event of a fault.
This tree structure is also used by the MPI-200 programming adapter software for the PC and the
User Interface in the sensor. The software is subdivided into Display, Electronics (signal inter-
face) and Sensor (conductivity measurement).
Sensor (conductivity measurement): Up to two analog outputs of the sensor for conductivity, con-
centration and temperature can be freely configured.
Conductivity: Two different conductivities can be set here, independently of one another. The upper
range limit can be freely selected. In addition, the customer can freely adjust temperature compen-
sation and damping.

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 > 0. This customized entry of support points is only possible in the “Setup” level
or higher. The temperature compensation, damping and upper range limit can also be set.
Temperature: Output of the medium temperature measured at the tip of the PEEK part on the sensor.
The temperature unit and response time can be adjusted here.

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. This can be adjusted as necessary.
•"No Media" warning signal: Current loop signal when the sensor is not immersed in a medium
→dry running.
•"Outside Spec." warning signal: Current loop signal if an operating state is outside of the spec-
ified range. The measurement accuracy can no longer be guaranteed.
•"Global Failure" error signal: Current loop signal if a malfunction occurs, for example if the
device fails.
•Signal limit for under range and over range: Lower or upper limit of the current loop signal
that is still valid and linear when output below 4 mA or above 20 mA.
•"Underflow/overflow" error signal: Current loop signal is below or above the under range or
over range limit.
•Signaling Simulation: Simulates the current loop signal, where the entered parameter value
briefly replaces the source value.
•LED configuration: These two LEDs can be configured as required. The procedure is described
in section 6.3.
A list of the parameters set in the conductivity sensor is included with the delivery. These param-
eter values, as well as those changed by the users themselves, can be printed out using the MPI-
200 programming adapter via File →Parameter Data →Print and can also be exported as a file
to the PC (via File →Parameter Data →Export Data File (*.xml)).
When making the settings, note the help texts in the MPI software for each parameter. They
provide useful information on changing the selected parameter.
6.3 Settings using the MPI-200 programming adapter
The MPI-200 programming adapter is connected to the ILM-4 conductivity meter via the external
MPI-200-F adapter piece. It must be ensured that the ILM-4 conductivity meter is permanently con-
nected to the supply voltage while the parameters are being set.

After the sensor is connected to the PC and the user software is opened, the following window ap-
pears:
1. Information on the current process value
2. Buttons for changing the parameter setting
3. Information on the current source value
4. Adjustable PC parameters
5. Adjustable sensor parameters
Clicking on the + in the menu opens a submenu
in which parameters can be adjusted.
Note:
For further settings, please see also the description in the MPI-200 product information.
To set or change parameters directly in the sensor (see section 6.2 "Settings using the Simple User
Interface"), you need the ID codes contained in the table below. This table only lists the most im-
portant ID codes.
Further ID codes can be found in the user software. To view these, right-click on "Info" by the pa-
rameter name. An info box appears with the respective ID (see graphic below):
Because the search number must have 6 digits, an additional digit is always added in front of the
five-digit ID (30034 in the graphic above). This digit depends on the node as follows:
4for changes to the display
3for changes to the signal interface
0for changes to the conductivity measurement
Because the signal selection is in the single interface node, the ID code for the "Signal selection"
example above is: 330034.
A list of all ID codes can be printed out via the PC user interface. To do so, click on File →Parameter
Data →Print to open the corresponding window and print out the complete list of ID codes.
