ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 1.3 Personal protective equipment Wear your personal protective equipment during all activities. Depending on the type of work to be carried out or if required by country- specific regulations, you must choose additional protective equipment.
EC guidelines. These are listed together with the applied standards in the corresponding EC declaration of conformity. ACO confirms the successful testing of the sensor by affixing the CE mark. RoHS The moisture measuring sensor complies with the substance restrictions of the Directive on the Restriction of the Use of Certain Hazardous Substances 2011/65/EU (RoHS 2).
The BMMS moisture measuring sensor is used to measure material moisture, mainly of bulk materials, in a production process. The BMMS moisture measuring sensor may only be used in a technically flawless condition, as intended, with an awareness of safety and dangers and in compliance with the manual! Malfunctions that could affect safety must be eliminated immediately.

ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de Assembly The BMMS moisture measuring sensor is mounted with a clamping ring as standard. The clamping ring is attached to a wall with three M6 screws. The moisture measuring sensor can be moved in the clamping ring over the entire length of the housing and can therefore be individually adapted to the wall thickness.

ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de Electrical connection 9.1 Sensor connection The BMMS moisture measuring sensor is connected via the connection box, ConBox. All incoming and outgoing signals and the supply voltage must be connected within the ConBox. The connection between the moisture measuring sensor and ConBox is pluggable.
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 9.2 Power supply For optimal operation of moisture measuring sensor, we recommend a single-phase power supply that delivers an unearthed, stabilised and galvanically isolated SELV/PELV/ES1 output voltage with 24V DC and approx. 1.5A.
• Integrated calibration data memory • Continuous or batch measurement • Temperature measurement • Temperature compensation of the electronics Moisture measuring sensors of the BMMS type enable full reproducibility of the data when replacing the sensor. Recalibration is not necessary.
Each moisture measuring sensor must therefore be calibrated individually to the material to be measured and the measuring application. The BMMS moisture measuring sensor is put into operation using the BMMScontrol software and calibrated within the process. Note:...
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 12 Maintenance, cleaning and repairs 12.1 Maintenance Check the moisture measuring sensor at regular intervals for deposits, caking and damage to the housing and the measuring surface. If damaged, the sensor must be replaced.
Take the device directly to a specialised recycling company and do not use the municipal collection points for this. You are also welcome to send the moisture measuring sensor back to ACO. We take care of the proper disposal.
15.1 Installation Installing the BMMScontrol software on your Windows PC is a simple process. It allows you easily to put the BMMS moisture measuring sensor into operation or calibrate. Take the installation file from the included USB stick. Double-click the installation file to start the installation process.
15.2 Programming cable and drivers The BMMScable is required to establish a connection between the Windows PC and the BMMS moisture measuring sensor with ConBox A. The parameterisation cable is a USB cable with an integrated RS485 interface. There is a USB A plug on the PC side and a Mini DIN plug on the sensor side.
To operate the BMMScontrol software, a licence is required, which is included with every software purchase. The license is hardware-bound and non-transferable. After installing the software, the license must be requested from ACO using the automatically generated request code. Please proceed as follows: Open the BMMScontrol software and open the “License”...
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 15.4 Structure of the BMMScontrol software The software is clearly structured and user-friendly. It allows the user to easily navigate through the sensor settings via tabs. The toolbar is visible at the top, the current sensor values are visible at the right edge and the most important settings are visible in footer.

ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de The counts and moisture can be evaluated directly in the respective graphs. To do this, pause the graphs by clicking on the “Pause” button, then click on the “Pen” button to delimit the area to be measured with two vertical lines.
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 15.7 “Sensor” navigation tab The Offset, Filter and Current Loop Interface settings are made in the “Sensor” navigation tab. With the input field "Offset," the moisture sensor is calibrated to 0.00 Counts in the removed state and with the measuring surface exposed to air.
Calibration and material switching are carried out in the “Calibration” navigation tab. The BMMS moisture measuring sensor can store eight calibration curves. Each of these calibration curves can be named with 8 ASCII characters. A calibration curve can consist of a maximum of eight points.
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de With the “Material Switch” button you can alternate between the eight individual materials during operation. The material that is currently active is displayed in the footer. With the “Send Points” button, changes to the calibration are transferred to the moisture measuring sensor.
ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de 15.10 “Batch“ navigation tab The “Batch” navigation tab is used to activate batch mode and set the required parameters. If the batch mode is active, material batches are automatically recorded based on the measured values and the average calculation is started and stopped.

ACO · Feuchtemessung · Moisture Measurement · www.acoweb.de The “Stop Delay” field is used to set the time after which the batch measuring stops. The batch measuring stops after the measured value has left the measuring window and the time has expired. Fluctuations and interruptions that are smaller than the set time are ignored.
