2. Function

The M-Sens 2 FD sensor functionality is based on precise high-frequency measurement and direct digitalization of measured values, where from results a high resolution. As the material surface and capillary moisture inﬂuences strongly its speciﬁc conductive capacity, the moisture can be measured exactly by a constant averaged bulk density. By way of support, any ﬂuctuations of the measuring value caused by the bulk density are balanced through an internal ﬁlter function. Temperature-related ﬂuctuations of the measuring value are automatically compensated by the sensor. On the installed system, the calibration is a matter of pushing a button and entering the moisture reference value.

2.1 Flow detection function

The M-Sens 2 FD is also able to detect if the material in front of the sensor is ﬂowing or not. This function can help you to validate the accuracy of the moisture measurement and quickly detect process failure such as a defective screw conveyor.

If activated, the ﬂow detection function will create an alarm via the relay. See “Alarm” menu.

4. Mounting and installation

4.1 Delivery range

• Evaluation unit in DIN Rail housing or ﬁeld housing

• Sensor

• Operating instructions

• C1-Box or C3-Box

• Welding ﬂange

4.2 Auxiliary

• Screw driver 2.5 mm

• Allen key 5 mm

4.3 Mounting of the sensor

M-Sens 2 FD is designed for continuous moisture measurement. Most important conditions for correct measurement is the right choice of the mounting place of the sensor. That is, when using chutes or conveyor belts, it is very important to have a almost even material height in front of the sensor window.

• The ﬂange is welded without sensor and dummy plate in the opening at determined mounting place. Sensor and dummy plate are mounting by means of plumbing lubricant. For applications without overpressure it is possible to renounce the 2 sealing rings.

Attention!

The ﬂange mustn’t be welded together with the sensor or dummy plate (incl. the sealing rings).

APPLICATIONS - PRACTICAL EXAMPLES

• Installation in a screw

The installation of a moisture sensor in screw feeders proved to be very advantageous, since the material passes by the sensor window in even intervals and with relatively constant bulk density.

• Installation on a conveyor belt

By means of the online moisture measurement of solids on a conveyor belt, the operator can react in due time if the material is too humid or too dry. In consequence, plugging of subsequent aggregates can be prevented.

• Installation in a bin

Another installation alternative is to mount a sensor at a bins outlet. Due to constant bulk density in case of a ﬁlled bin, the sensor ﬁnds an almost unchanging measuring ﬁeld for monitoring the residual moisture. Thus, M-Sens 2 FD avoids that too damp material reaches the next production level or arrives into the loading.

• Control of dryer by means of moisture measurement

After the material, lying on the belt, has passed through the dryer tunnel, it gets withdrawn from the hot air zone. At the end of the belt the dried material falls in a screw conveyor which transports it to the processing. The operator queries the following points: Has the material reached really the desired residual moisture value? That is, has he chosen the right cycle time and temperature?

M-Sens 2 FD provides accurate and reliable online moisture values for the process control, by which constant moisture in close tolerances of the output material can be met. This process optimization enables the operator to manage high savings and quality improvements.

• Moisture measurement in a mixer

M-Sens 2 FD can be installed, even later on, in all types of mixers. The measuring values logging is done by within the moving material during the mixer procedure. With the measured moisture value of the material in the dryer process parameters like detention time and dosage quantity can be controlled. For this purpose M-Sens 2 FD is connected to a PLC or another process control system.

4.4 Mounting of the transmitter

The transmitter can be installed at a maximum distance of 300 m from the sensor. A cable of type “Ölﬂex Classic 110 CY” is recommended. The cable should be four wired, twisted and shielded. A minimum cable cross-section of 0.75 mm² should be observed. For distances more than 150 m the cable cross-section should be adjusted.

The housing is prepared for DIN Rail mounting according to DIN EN 60715 TH35.

6. Commissioning

At the ﬁrst commissioning of the M-Sens 2 FD it is necessary to calibrate the sensor.

Please consider:

• Correct connection between sensor, C1-box and evaluation unit.

• Correct installation of the sensor in the process.

In case of negative results in spite of consideration of the points as stated above, please contact SWR.

Commissioning of the M-Sens 2 FD

After the delivery the sensor is not calibrated to the product(s), so each calibration and parameterization has to be executed during the commissioning. Therefore it is necessary to assign the measured moisture to the desired display and to the initial value. The menu functions are very self-explanatory. In the following a short introduction to the menu overview:

Menu are accessible via PC software or the touch screen (ﬁeldhousing unit only) – See Operator Interface Basic function For the measurement using the sensor, at least 2 measuring points should be

calibrated as a reference point and the corresponding moisture value should be entered. To do this, the reference point measurement is started in the calibration. After the measurement, the analysis device expects the input of the moisture content determined in the lab. While the material is conveyed (in the loading state), the 2nd point is set to a known moisture value and the calibration is also carried out. If only one material moisture value is available, then minor moisture ﬂuctuations and corresponding ﬂuctuations in the moisture values determined in the lab can be used to save at least 2 calibration points.

Adjustment Alarms The user can select operation modes “None”, “Min”, “Max” or “FLOW” in the

menu Alarms (3.1). A shortfall or exceeding of an adjustable measuring value can be output via the alarm relay as “open” or “close” (3.5). The Flow Detection function is available by choosing “FLOW” in the alarm menu. This alarm will trigger when selected “Noise” value is reached.

In menu Sensor Alarm (3.6), the user can select “OFF” “ERR” or “Proc”. By choosing “ERR”, alarm will be on in case of sensor error, by selecting “PROC”, alarm will be on in case of fatal sensor errors/failure and process indicators.

Analog output is modiﬁed in menu 4 and can be adjusted to user requirements here (e. g. 0… 20 mA). The setting of the minimum and maximum output current can be setup on 4.1 and 4.2. The alarm value can be deﬁned on 4.3 and alarm type on 4.4. The exact calibration of the 4 mA and 20 mA value are done via menu

4.5 and 4.6 and 4.7. This operation require the use of a calibrated multimeter. The measuring range ﬁlter makes it possible to adapt to slower recording

devices or continuous output at the analogue output (power output).

Calibration points The measurement can be checked for linearity based on varying moisture values. To improve accuracy, these should be determined respectively. In case of deviations, the non-linearity can be corrected through a table of support points. Based on the points that are selected and speciﬁed in menus

2.4.1 etc. (a minimum of 2 during ﬁrst commissioning), a correction value can

now be entered for the actual moisture value. (This value can be changed later.) A maximum of 5 support points are available.

Saving changes After changes are made, they can be saved using the menu item program

device. The change is carried out once Overwrite calibration is conﬁrmed.

C1-Box Is only used when the distance between sensor and analysis unit exceeds 2 m.

For the adjustment of user requirements with regard to material, measuring units etc.

C3-Box Is only used when 2 or 3 sensors are connected.

The current output can be calibrated so that the zero point (output of 4 mA) is set to the background noise of the measuring point. If the background noise decreases due to process changes, sensor wear or other ageing effects, a signal of less than 4 mA can be output at the analogue output. In this way, a zero offset can be detected (zero point drift). If this function is not desired for process engineering reasons, the zero point must be speciﬁed for the calibration to a raw value of zero and/or the 4.1 MIN limit set to 4 mA.

If the settings of the 4 mA or 20 mA signal are changed, the checkbox Overwrite calibration must be set. If the checkbox is set the changed parameters can be sent to the transmitter by clicking on Device program.

8. Operator interface

The transmitter is a multi-sensor transmitter. It is therefore strongly recommended to check before commissioning whether the correct sensor is selected in menu System.

The operator interface differs depending on the system design:

• DIN Rail housing without touchscreen, operation via PC software only

• Field housing with display, operation via PC software or touchscreen

8.1 Differences between the DIN Rail and ﬁeld housing transmitter

The transmitter in the DIN Rail housing is only a part of the functions available in the ﬁeld housing. The following overview clariﬁes the differences between the two versions.

Function Field housing DIN Rail

Menu system

• via PC software yes yes

• via display yes no

Measurement value display current output yes yes

Pulse output for control of solenoid valves yes no

Alarm system relay output yes yes

Remote control digital input yes no

Autocorrect analogue input yes no

Error output

• on current output yes yes

• at relay yes yes

• via PC software yes yes

• via display yes no

• on status LED no yes

The transmitter in the DIN Rail housing is conﬁgured exclusively via a USB connection or RS 485 ModBus connection and a PC program. For the transmitter in the ﬁeld housing, all functions can be conﬁgured via the touch-sensitive display. The PC conﬁguration is also possible with the transmitter in the ﬁeld housing.

The menu items on the display and in the PC software are numbered in a uniform manner so that they can be referred to later on.

8.2 Display

The display is touch-sensitive. Available keys are displayed directly in context. When the measuring system is ﬁrst started, a query is initiated to select the language and sensor. If no selection is made, the initialization disappears and the German language with a SolidFlow 2.0 sensor is selected.

For reasons of simplicity, a further display menu screen has been dispensed with. The display screens are directly derived from the menu structure in section 6.4.

Protection against unauthorised use:

If a password has been entered in menu 7. System in 7.6 Password, which is different to the “0000” default setting, you will be asked to enter a password when attempting to access the menus. After the password has been successfully entered, the menus will be unlocked for approx. 5 minutes (from the last menu entry).

8.3 PC interface

Communication with a laptop or PC is carried out on the DIN Rail as in the ﬁeld housing version optionally on the terminals via an RS 485 or on the front side via a USB interface.

✔ The RS 485 connection is attached to the transmitter in the ﬁeld housing at the ModBus A (+)

and ModBus B (-) terminals. On the DIN Rail version, these connections are nos. 12 and 11, accordingly. RS 485 is a bus connection; the ModBus address and the baud rate can be set on the device. Upon delivery, the communication parameters are set to:

8.3.1 ModBus address 1

8.3.2 Baud rate 9600, 8, E,1 An RS 485 to USB adapter can be purchased from ENVEA - SWR engineering.

✔ For the USB connection to the DIN Rail version is a standard USB-A-B cable included.

The USB connection is a point-to-point connection that is not BUS-capable. The ModBus address and the baud rate for the front-side connections cannot be changed and are always:

8.3.1 ModBus address 1 (or the device answers to all addresses)

8.3.2 Baud rate 9600, 8, E,1 When connected to the PC for the ﬁrst time, any interface drivers enclosed with the transmitter must be

installed. After starting the software, the communication parameters must ﬁrst be entered accordingly.

These can be found in the top left of the program window. The COM port to be conﬁgured is displayed in the device manager.

Communication is established by clicking on “Read device”. The acknowledgement message “Parameter read in” is displayed. If an error message is displayed instead, check the communication parameters and cable connections between the PC and the transmitter.

The edited data is transmitted to the transmitter via “Device program”. Critical data concerning the ModBus communication and the calibration must be conﬁrmed before the parameters are transmitted to the transmitter:

✔ If, when saving the parameters in the transmitter, the system calibration data is changed, this action

must be conﬁrmed by checking “Overwrite calibration”.

If, when saving the parameters in the transmitter, the system interface parameter are changed, this

✔

must be conﬁrmed by checking the selection “Overwrite baud r./address”.

8.3.5 On-Line representation

By clicking on “On-Line representation” button you will make a new windows appear. It will display: Sensor RAW value

Measured value Sensor electronic temperature Sensor(s) status Noise value

Datalogger is enable when ticked.

In addition, with the PC software,

• the transmitter parameters of the transmitter can be saved in a ﬁle (Save conﬁguration)

• the transmitter parameters can be loaded from a ﬁle (Load conﬁguration)

• the transmitter parameters can be printed via the Windows standard printer (Print conﬁguration)

• the measured values can be logged in a data logger ﬁle (enter the ﬁle name and storage rate, and activate the data logger on the online display)

The software language can be set by right-clicking the “Sprache/Language/Langue” ﬁeld in the bottom program line on “Deutsch/English/Français”.

Protection against unauthorised use:

The PC interface does not have a password prompt as it is assumed that only authorised personnel will have access to the PC and the software. The password to operate the display can be read and changed in menu
