around by media and no bubbles can occur. It therefore is advisable to install the
device in rising pipes. Refer to the drawings below for reference.

Operating Manual ITM-51/ITM-51R 5
6.2 Hygienic installation requirements
Dimensions for hygienic installation with Tri-Clamp
Tri-Clamp: T < D
Tri-Clamp extended: T < (D-d).
Recommended mounting positions
ITM-51 in vertical pipe
ITM-51 in horizontal pipe
Conditions for hygienic installation according 3A and EHEDG
•The ITM-51 / ITM-51R is designed for CIP/SIP cleaning. The sensor can withstand a
maximum of 140 °C / 120 min.
•The mounting position must guarantee self-draining properties.
•If mounted with a Tri-Clamp connection the mounting tee, mounting position and
gasket need to follow the actual 3A or EHEDG standards and guidelines.

Operating Manual ITM-51/ITM-51R 6
Not permitted mounting positions using Tri-Clamp
Installation from above or below should be avoided with Tri-Clamp. This can lead to
incorrect measurements due to air accumulation or deposits.
6.3 Configuration
The ITM-51 relative turbidity meter is set to operate without requiring special adapta-
tions. In isolated instances, some parameters may need to be adjusted. The parameteri-
zation may be changed using the PC-based MPI-200 programming adapter, IO-Link or the
User Interface directly on the sensor. This can be performed either directly on location or
in the office in a dry simulation.
The sensor is delivered with the following default settings:
Analog Output 1 (X45 on terminal connection 4 and 5):
turbidity 1 with measurement range 0…100 %TU
Relay Output (X67 on terminal connection 6 and 7): switching output with 10 %TU set point
The parameter list accompanying the sensor contains the sensor settings for analog output 1 (ter-
minals 4 and 5) under X45a and for relay output (terminals 6 and 7) under X67.
The ITM-51 relative turbidity 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 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 interface) and
Sensor (turbidity measurement).
When setting the parameters, please note that a hierarchy of authorization levels exists (0 Mon-
itoring, 1 Adjustment (QuickSetup), 2 Setup 3 Calibration):

Operating Manual ITM-51/ITM-51R 7
Sensor (turbidity measurement):
The analog output of the sensor for turbidity can be freely configured.
Turbidity: Two different turbidity ranges can be set here, independent of each other. The upper
range limit can be freely selected. Switching between the both ranges can be done with the A53/I53
signal module while using the digital switching input X3. This function is not available with the
A42/I42 and A52/I52 signal modules.
Switching output (only applicable for A52/I52 and A53/I53 electronics): A setpoint for turbidity as
well as the working direction of the switching output can be selected.
Electronics (Signaling interface):
•Signal selection for the 4…20 mA signal: Selection between Turbidity 1 or 2 and the applica-
ble turbidity category
•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 underrange and overrange: 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 underrange or
overrange limit.
•Signaling Simulation: Simulates the current loop signal, where the source value is briefly re-
placed by the entered parameter value.
•LED configuration: These two LEDs can be configured as required. The procedure is described
in section 6.2.2.
A list of the parameters set in the turbidity sensor is included with the delivery. These parameter
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.
6.4 Settings using the MPI-200 programming adapter
The MPI-200 programming adapter is connected to the ITM-51 turbidity meter via the external MPI-
200-F adapter piece. It must be ensured that the ITM-51 turbidity meter is permanently connected
to the supply voltage while the parameters are being set.

Operating Manual ITM-51/ITM-51R 8
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 User Inter-
face"), you need the ID codes contained in the table below. This table only lists the most important
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 turbidity measurement
Because the signal selection is located 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.

6.5 Settings using the User Interface
The software structure of the User Interface is similar to PC software version.

Operating Manual ITM-51/ITM-51R 12
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. The button functions are as follows:
Notes on setting using an ID number
1) Press and hold the right button, the display jumps to the menu.
2) Confirm right key 2x briefly to position "ID search".
3) Press and hold the right key and select the desired item "ID Search
4) Press and hold the right key, then enter the ID number from right to left.
Proceed as follows:
a) Select the desired position (navigation with right/left - press the left key): Change position
to the left, press right key, change position to the right.)
b) Press and hold the right-hand key at the desired position until the field is highlighted in
grey, then enter the numerical value with the right/left keys and confirm with the right-
hand key for a long time until the number is no longer stored. Then enter the next digit.
c) When all digits have been entered, press the left or right key until all digits are highlighted
in gray.
d) Next, press and hold the right key. The system then jumps to the selected parameter and
this can now be entered / changed in the same way. Start here - again, press and hold the
right button.
e) For some system-relevant parameters, a confirmation prompt will appear asking whether
the change should be saved or not.
5) The input can be aborted by pressing and holding the left button. The setup can be canceled by
pressing and holding the left button several times.
•Pressing the right button means that the parameter is changed or saved.
•Pressing the left button means leaving the setting without changing it.
6.5.1 Screen display
After the sensor parameters have been adapted/changed, or after the sensor is switched on and
no change is made, the sensor switches to the display mode after a certain period. In the display
mode, the main measurement value is shown as described in the picture below. If a second output
option is available (only for electronic versions A52, A53) the actual value is shown in the bottom
line of the display.

6.5.2 LED configuration
The display unit features 2 LEDs that can be individually configured. The LED to the left of the
display is LED 1 while the one to the right is LED 2.
The following options can be selected when setting the LEDs:
•Signal Selection: The following signals can be selected: turbidity 1 and 2.
•Output function, direction of action, switch point entry method, switch point, hysteresis
•Switch ON Delay, Switch OFF Delay: The digital output is switched on or off with the delay
set here. Values can be set between 0...30 s.
•Warn-S: no Media, Warn-S: Outside Spec., Err-Sig: Underflow, Err-Sig: Overflow, Err-Sig:
Global Failure: The effect of each parameter on the LED display can be set. The following
can be selected: "No Effect on Output", Output Fast Blinking" (0.4 s interval), "Output Slowly
Blinking" (1 s interval), "Output ON" (LED on continuously) and "Output OFF". "Output" refers
to the LED here.
•Signaling Simulation: The source value is briefly replaced by the entered parameter value.
The following situations can be simulated: "Output OFF", "Output ON", "Output Slowly Blink-
ing" and "Output flashes rapidly". "Output" refers to the LED here.
The turbidity sensor is delivered with the following factory settings for the LEDs:
•LED 1 (left LED)
If the sensor is in a normal state, this LED is off.
Err-Sig: Overflow: The LED flashes every second if the sensor registers an overrange error. If
the sensor is in a normal state, this LED is off.
Err-Sig: Temperature Error: The LED is permanent on if the sensor registers a medium
temperature above 130°C permanent.
All other errors are indicated while the LED flashes in short intervals.
•LED 2 (right LED)
Condition of the switching output: LED lights up continuously if the presetted turbidity
range is attained. The working direction of the switching output and therefore the behavior
of the LED can be changed.

6.6.3 Setting of customer-specific turbidity / %solids curve via PC software
After the PC software is started, a customer-specific curve for the turbidity can be entered via the
following node: Turbidity Measurement →% solids →(+). Values need to be entered for at least
2 X and Y points. Up to 8 support points for X and the associated Y values can be entered to estab-
lish the relationship between turbidity (X) and % solids (Y). The Y values together with the associ-
ated X values form coordinates that act as support points for the linearization curve. If 0 is entered
for any of these points, that support point is deactivated.
X-Point 01...X-Point 08 (Turbidity): This parameter is used to define the customer-specific meas-
urement range of the turbidity. Values can be entered from 0…300 kNTU.
Y-Point 01...Y-Point 08 (% solids): This parameter is used to define the customer-specific meas-
urement range. Values can be entered from 0...100%.

Operating Manual ITM-51/ITM-51R 17
7Installation of the “Large User Interface”(LUI)
1. Remove the plastic cover (continue with step 4), or remove the puck with the mounted small
display (continue with step 2)
2. Remove the small display
3. Install the puck in the sensor head
4. Mount the 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.
If the display is being installed while energized, it is necessary to press both buttons simultane-
ously for > 10 s after the display is installed to activate the display.
7.1 Retrofitting the display if a display was not yet installed
After removing the plastic cover, the large display can be inserted in the head of the sensor. The
tabs (Fig. 2) must be inserted in the appropriate openings on the puck (Fig. 1). Then the display can
be easily pressed onto the puck. No wiring is required.
Note: After the Large User Interface is mounted, the sensor can only be operated on this display
since the display conceals the connector for the MPI-200 adapter. If operating the sensor using the
programming software is preferred, the display must be removed. Then the connector of the pro-
gramming adapter can be plugged in.
Fig. 1
Fig. 2
Fig. 3
Attention: The connector of the programming adapter (Fig. 3) must be connected in the correct
direction →the green spacer must face the cable exit (M12 connector or PG).
Remove the plastic cover: To do so, bend the tabs
slightly inwards with a screwdriver to be able to
remove the cover easily.

Operating Manual ITM-51/ITM-51R 18
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. 1). 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. 2).
Push the puck puller all the way into the sensor head and push
the disk as far as possible toward the sensor head so that the
arms of the puck puller firmly grasp the puck.
Pull the puck with the display out of the sensor housing and
finally pull off the small display from the puck.
Now the puck without the display can be properly positioned and installed back in the sensor head
and the wiring can be reconnected to the cable terminal. Then the large display can be mounted →
see "Retrofitting the display if a display was not yet installed".
7.3 Operating the large display
The large display (LUI) is operated in the same way as the small display (SUI). It is operated using two
operating buttons below the display:
After the sensor is started, the screen saver appears in which the process values of the sensor are
displayed one after the other. To reach the start page from here, press one of the two buttons briefly.
