First steps

Unpacking the device

•  Unpack the device.
•  Next, make sure that it is not damaged and that no parts are missing.
•  DO NOT remove the transport protection from the device.

Checking the delivery content
Use the following list to check if the delivery is complete:

•  MF-P-HTD Paper moisture sensor with installed IR temperature sensor and paper guide roller set
•  connection cable for power supply (1.9 metres) with 5-pole plug
•  user manual
•  transport protection

Options:

• Modbus TCP interface
• Analog output
•  PC-Software MF-P-HTD Sense Ware – Software for moisture calculation, type calibration, measured value display and measured data management (only possible in connection with Modbus TCP interface!)
•  Power supply Power over Ethernet (PoE) (Only possible in connection with Mod-bus TCP interface!)

Installation instructions
Please follow these instructions:

•  The installation position has to be chosen so that the sensor does not condense when operating. Be careful if installing in a cool environment, where the paper or cardboard is very warm!
•  Avoid strong mechanical impacts or loads.
•  Do not install the device near strong electromagnetic radiations.
• Ensure that the paper lies on the paper guide rollers of the MF-P-HTD sensor dur-ing operation.
• The sensor must always be installed above the paper web.
•  Do not place any objects under the sensor! There must be a free space of 300 mm!

Mechanical installation
ATTENTION
Sensitive sensor plate
The white sensor surface consists of a thin ceramic plate. This can be destroyed by mechanical pressure!

• When installing the sensor, remove the provided transport protection as late as possible!

The MF-P-HTD sensor has to be fastened with the mounting plate to the machine. For this, different holes are placed on the mounting plate. Use four screws (M8 or M6) to attach the sensor to the machine.
The sensor can also be installed on a linear guide.

• Please ensure that the sensor has to be mounted always above the paper web and that there must be a free space of 300 mm below the sensor!

1.  The sensor has to be installed in such a position, that the two paper guide rollers always touch the paper web .

   • For this, the sensor must be tightened against the paper web.
     Installation height of the sensor
     Ensure the correct installation height of the sensor.
     If the paper guide rollers do not always touch the paper web, incorrect measu- rements will occur.

2. For an easier installation, the mounting plate can also be completely unscrewed from the MF-P-HTD sensor .

   • Therefore, the four lowest M8 nuts have to be released .

3. The height of the sensor can be adjusted with the four M8x50 hexagon screws.

   • First, release the two marked M8 hexagon nuts for each screw.
   • With these nuts the desired height can now be adjusted.
   • Then tighten all the nuts again.

4. The contactless infrared temperature sensor has a 10:1 optics.

• During the measurement, there must always be paper in the measuring field of the temperature sensor.

Sketch MF-P-HTD Pin assignment power supply and analogue output (option)

ATTENTION
Electronic damage caused by incorrect cable connection
Incorrect assignments can cause serious electronic damages.

• Connect all cables correctly.

Electrical damages caused by extension problems
Extension problems can cause electronic damages.

• The cross-section of the extension may not be under 0.25 mm2.

ATTENTION
Measuring signal interference caused by missing potential equalization
A missing potential equalisation can transfer interference signals to the measuring signal.

• The potential equalisation GND (shielding) must be connected.

Pin assignment Modbus TCP (option)
A 4-pole M12 connector with D-coding (M12-D) is required here.

• A CAT6 or higher type cable is recommended.
•  Every cable type must be equipped with a shielded M12 round plug D-coded on the sensor side.
• The cable shield must be earthed in this installation setup!

Laying the power supply or transmission line

• The cable cannot be laid in the range of interference fields.
•  The transmitter cannot be used near electromagnetic interference fields.
•  The cable should not be strongly bent.
•  Permissible cross-sections for installation have to be considered.
• The cable length must be kept as short as possible.
• Should an extension be necessary, the cross-section of the extension may not be under 0.25 mm².
•  The potential equalisation GND ( shielding ) must be connected.

 Measurement

Requirement: The sensor is powered and running (the red LED flashes in 5 second intervals). An adjustment (adjust) was successfully completed in the last two weeks.

MF-P-HTD with Modbus TCP option and Humi Sense Ware software

With these options it is possible to calculate, visualize and document the water content of the paper. However, this requires a paper calibration and the correct paper
classification (grammage) in the HumiSenseWare software. The paper calibration is stored in the HumiSenseWare as well. This software also automatically compensates the different paper temperatures.
The HumiSenseWare manual can be found as a help file in this software.

MF-P-HTD with analogue output option

To calculate the water content with the analogue output option, a separate PLC programme is required. The value of the MF-P-HTD analogue output is not the water content, it is the internal value of the MF-P-HTD sensor!

 Care and maintenance

Regular cleaning and maintenance will ensure that your device remains in perfect condition as long as possible.

ATTENTION
Sensitive sensor plate
The white sensor surface consists of a thin ceramic plate. This can be destroyed by mechanical pressure!

• When installing the sensor, remove the provided transport protection as late as possible!

Adjustment of the device

Every two weeks an adjustment must be run (adjust). This procedure guarantees a long term stability of the moisture measuring.
Requirement: The device must have a temperature between 20.0 °C and 26.0 °C and must be on for at least 30 minutes.

1. Remove the paper or cardboard under the sensor surface
   •  Make sure there is nothing under the sensor sur-face.
2.  Press the button with the red LED until the LED lights up constantly .
   •  When you release the button, the adjustment begins!
   • During adjustment, the red LED flashes every second.
3.  Once the adjustment is completed, the red LED goes out for a moment and then flashes again every 5 seconds.

Reset

• Press the button with the green LED.
• The button with the green LED lights up for one second and the button with the red LED flashes rapidly for this period.
• The device will now restart.

Cleaning the device

ATTENTION
Device damage caused by wet cleaning
Water or cleaning products can damage the device if they get into the device.

• Only dry cleaning (compressed air) is recommended.

ATTENTION
Sensitive sensor plate
The white sensor surface consists of a thin ceramic plate. This can be destroyed by mechanical pressure!

• Take care of the sensitive sensor surface during cleaning!

ATTENTION
Scratching the IR temperature sensor
Cleaning the optical system with a tissue could cause scratches and irreparable damages.

• Clean only with dry compressed air!
