•The ITM-51 / ITM-51R is designed for CIP/SIP cleaning. The sensor can withstand a maxi-
mum of 140°C/120min.
•The mounting position must guarantee self-draining properties.
•If mounted with a TC 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
7Parameterisation
The ITM-51 relative turbidity meter is set to operate without requiring special adaptations. 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 directly on the sensor. This can be per-
formed either directly on location or in the office in a dry simulation.
The sensor is delivered with the following default settings:
Output 1 (terminals 4 and 5): turbidity 1 with measurement range 0…100 %TU
Output 2 (terminals 6 and 7): switching output with 10 %TU set point
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 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 Monitoring, 1
Adjustment (QuickSetup), 2 Setup 3 Calibration):
0 “Monitoring”:The parameter cannot be changed in the ITM-51 sensor.
1 “Adjustment”: The main parameters for turbidity measurement can be adjusted/changed.
The farther up you move in the hierarchy, the more parameters can be changed at the customer site.
Sensor (turbidity measurement):
The analog output of the sensor for turbidity can be freely configured.
Turbidity: Two different turbidities can be set here, independently of one another. The upper range limit can
be freely selected. Switching between the both ranges can be done with the A53 electronics while using the
digital switching input E1. This function is not available with the A42 and A52 electronics.
Switching output (only applicable for A52 and A53 electronics): A setpoint 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 applicable turbid-
ity 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 specified
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.

Operating Manual ITM-51/ITM-51R 7
•Signaling Simulation: Simulates the current loop signal, where the source value is briefly replaced by
the entered parameter value.
•LED configuration: These two LEDs can be configured as required. The procedure is described in sec-
tion 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.
7.1 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.
After the sensor is connected to the PC and the user software is opened, the following window appears:

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 Interface"), 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 parameter
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.

7.2 Settings using the User Interface
The software structure of the User Interface is similar to that 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 parameters. The button
functions are as follows:
7.2.1 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 meas-
urement 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.
To leave the display mode and create settings on the sensor, press the right button next to the display
twice to enter the menu. The sensor then displays the start page, from where the settings can be created.

7.2.2 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 fol-
lowing situations can be simulated: "Output OFF", "Output ON", "Output Slowly Blinking" and "Out-
put 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.
7.3 Examples of sensor settings
Several examples of settings that can be created on the User Interface or on the user interface of the PC
follow.
The device is operated using two operating buttons on the left and right next to the display. When the sensor
is in display mode, the right button must be pressed short to leave the display mode. To reach the start page
of the menu the right button needs to be pressed long. The buttons function as follows:

7.3.3 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 establish the relationship between
turbidity (X) and % solids (Y). The Y values together with the associated 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 de-
activated.
X-Point 01...X-Point 08 (Turbidity): This parameter is used to define the customer-specific measurement
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 measurement
range. Values can be entered from 0...100%.

Operating Manual ITM-51/ITM-51R 16
8Installation of the „Large User Interface“ (LUI)
1. Remove the plastic cover (continue with step 4), or remove the puck with the mounted small display (con-
tinue 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 requires the
usual precautionary measures when working with electronic components.
If the display is being installed while energized, it is necessary to press both buttons simultaneously for
> 10 s after the display is installed to activate the display.
8.1 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 soft-
ware is preferred, the display must be removed. Then the connector of the programming adapter can be
plugged in
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 17
8.2 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 pull the
small display off of the puck.
Now the puck without the display can be properly positioned and installed back in the sensor head and the wir-
ing 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".
8.3 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. Further information on
operating the display can be found in the quick start manual and in the operating manual for the modular sen-
sors (ITM-51, ILM-4,…).
