1.2 Documentation
The following documentation types are available in the Downloads section of the Endress
+Hauser website (www.endress.com/downloads):
For an overview of the scope of the associated Technical Documentation, refer to the
following:
•W@M Device Viewer (www.endress.com/deviceviewer): Enter the serial number from
nameplate
•Endress+Hauser Operations App: Enter the serial number from the nameplate or scan
the 2D matrix code (QR code) on the nameplate
2 Basic safety instructions
2.1 Requirements for personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill the
following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Personnel must be authorized by the plant owner/operator.
‣Be familiar with federal/national regulations.
‣Before starting work: personnel must read and understand the instructions in the manual
and supplementary documentation as well as the certificates (depending on the
application).
‣Personnel must follow instructions and comply with general policies.
The operating personnel must fulfill the following requirements:
‣Personnel are instructed and authorized according to the requirements of the task by the
facility's owner-operator.
‣Personnel follow the instructions in this manual.
2.2 Designated use
Application and media
The measuring device described in this manual is intended for the continuous moisture
measurement of a wide variety of materials. Because of its operating frequency of approx.
1 GHz, the device can also be used outside of closed metal vessels.
If operated outside of closed vessels, the device must be mounted in accordance with the
instructions in the "Installation" section. The operation of the devices does not present any
health risk. If the limit values specified in the "Technical data" and the conditions listed in the
manual and additional documentation are observed, the measuring device may be used for the
following measurements only:
• Measured process variables: material moisture, material conductivity and material
temperature

Basic safety instructions Solitrend MMP42
6 Endress+Hauser
To ensure that the measuring device remains in proper operating condition throughout the
operating period:
‣Use the device only for media to which the process-wetted materials are sufficiently
resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Clarification of borderline cases:
‣For special materials and media used for cleaning, the manufacturer is happy to provide
assistance in verifying the corrosion resistance of medium-wetted materials, but disclaims
any warranty or liability.
Residual risks
Due to heat transfer from the process as well as power dissipation within the electronics, the
temperature of the electronics housing and the assemblies contained therein may rise to
70 °C (158 °F) during operation. During operation, the sensor can reach a temperature close to
the medium temperature.
Danger of burns from contact with surfaces!
‣In the event of elevated medium temperatures, ensure protection against contact to
prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
2.4 Operational safety
Risk of injury!
‣Operate the device only if it is in proper technical condition, free from errors and faults.
‣The operator is responsible for interference-free operation of the device.
Hazardous area
To eliminate the risk of danger to persons or the facility when the device is used in the
approval-related area (e.g. explosion protection, pressure equipment safety):
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of this manual.
2.5 Product safety
This device is designed in accordance with good engineering practice to meet state-of-the-art
safety requirements, has been tested, and left the factory in a condition in which it is safe to
operate.

4.4 Storage, transport
4.4.1 Storage conditions
• Permitted storage temperature: –40 to +70 °C (–40 to +158 °F)
• Use original packaging.
4.4.2 Transporting the product to the measuring point
Transport the device to the measuring point in the original packaging.
5 Installation
5.1 Installation conditions
• The device must be installed at a point in the process in such a way that ensures a relatively
constant material density, as the material density is directly related to the water content.
Where necessary, a bypass should be created or structural measures may be needed at the
place of installation to ensure that the material flow, and therefore the material density,
over the sensor is relatively constant.
• The measuring field of the device should be completely surrounded by material and the
material height must exceed the minimum sensor coverage (depending on sensor type and
moisture).
• The flow of material over the surface of the sensor should be relatively continuous. The
electronics module offers ways to automatically detect and bridge gaps in material in
intervals of seconds.
• No material deposits or buildup may form on the sensor surface, as this would falsify the
readings.
Longer averaging times increase the stability of the measured value.
5.2 Round sensor, short / middle
The short / middle round sensor can be installed using a mounting flange.

8 Commissioning
8.1 Analog outputs for measured value output
The measured values are output as a current signal via the analog output. The sensor can be
set to 0 to 20 mA or 4 to 20 mA.
Output 1 can be scaled at the factory, or can be subsequently scaled individually (user-
defined setting) using the remote display (optionally available), e.g. 0 to 10 %, 0 to 20 %
or 0 to 30 %
• Output 1: moisture in % (variably adjustable)
• Output 2: conductivity 0 to 20 mS/cm or temperature 0 to 100 °C (32 to 212 °F), this also
applies for the high-temperature version.

Commissioning Solitrend MMP42
20 Endress+Hauser
It is also possible to divide output 2 into two ranges to output both the conductivity and the
temperature, namely the 4 to 11 mA range for temperature and the 12 to 20 mA range for
conductivity. Output 2 automatically switches between these two windows every 5 seconds.
8.1.1 Possible settings for analog outputs
Therefore, there are several possible settings for analog outputs 1 and 2:
Analog outputs
Options:
• 0 to 20 mA
• 4 to 20 mA
The current output can also be set inversely for special controllers and applications.
• 20 to 0 mA
• 20 to 4 mA
Channels of the analog outputs
The analog outputs can be set differently to the following possible options:
Moisture, temperature
Output 1 for moisture, output 2 for material temperature.
Moisture, conductivity
Output 1 for moisture, output 2 for conductivity in the range from 0 to 20 mS/cm
(factory setting)
Moisture, temperature/conductivity
Output 1 for moisture, output 2 for material temperature and conductivity with
automatic window changeover.
Moisture range
The moisture range and the temperature range can be individually configured for outputs 1
and 2.
The moisture range may not exceed 100 %.
•Moisture range in %
• Maximum: e.g. 20 %
• Minimum: 0 %
•Temperature range in °C
• Maximum: 100 °C, this also applies for the high-temperature version.
• Minimum: 0 °C
•Conductivity in mS/cm
• Maximum 20 mS/cm
• Minimum 0 mS/cm
The sensors can measure conductivity in the range from 0 to 2 mS/cm, depending on the
sensor type and moisture. The output is set to 0 to 20 mS/cm at the factory.
