4. System summary
The DIGISYS with intelligent bus sensors is an independently operating moisture-measuring system, without
the necessity of installing indication and operating units. It is thus ideally suited for controls featuring a visu-
alisation system. The Interchange and evaluation unit can be installed compactly in a switch cabinet. A multi-
tude of interfaces can be realised for the overriding systems. An easy-to-use PC-software allows a quick and
precise calibration of the measuring channel.

ACO AUTOMATION COMPONENTS DMMS moisture sensor
5. DMMS moisture sensor
The DMMS sensor is a so-called "intelligent sensor", thus, the installed µ-processor allows complete solving
of the problem in one component, as well as an expanded functionality.
•Direct digital measuring procedure
•Calibration data memory
•Linearisation
•Inspection of thresholds
•Start / Stop control
•Mean value calculation
•Temperature measurement
•Temperature compensation
•Material-specific adjustment
•Digital interface / networking
•Error report
A precise calibration at the factory allows complete reproducibility over a wide temperature range. The costly
material-specific adjustment therefore is also possible for wider measuring channels and no readjustment is
necessary, in the case the sensor is replaced.
The sensor receives a measuring task from the DIGISYS Interchange and evaluation unit and makes avail-
able the ready-processed measuring result available at the precise required time. The data transfer is re-
duced to a minimum and the resources of controls which have a higher priority are less burdened.
Sensor assembly
The sensor can be installed in a container, guide shoe carriage, batching table or in a material chute using
the mounting flange. The sensor can be installed flush on wall thicknesses of 1 to 25 mm by shifting in the
flange.
•Open up a mounting hole in the wall partition - see master gauge
•Loosen the straining screw (E)
•Fix the mounting flange (C) with 3 countersunk screws (a) on the rear side of the wall partition, leav-
ing the nuts (d) loose
•Adjust the sensor in the flange until it is flush with the wall partition.
•Tighten the straining screw (E) first, and then the fastening (B)
•Clamp the sensor cable to the bus connection socket and tighten the cable gland

ACO AUTOMATION COMPONENTS
CAUTION Damage to the system.
•Do not open the cable clamp on the sensor.
•Do not strike the ceramic wear shield directly with a hammer.
•Install the sensor flush to prevent material encrustations or premature wear.
•Hot water from evaporation in the silo damages the sensor or leads to measuring discrepancies.
•The temperature inside the sensor housing may not exceed 80°C.
•The sensor may not be installed in immediate proximity to vibratory discharge aids (vibrators).
•When replacing sensors, do not cut away the connecting cable of the old sensor.
•When filling the silo for the first time, ensure that the sensor is protected against falling rocks.
•A mounting flange installed at a tilt in the sensor can fall out if it becomes overloaded.
•The 3 fastening screws (a) and the straining screw (E) must be made of stainless steel.
Maintenance
•Correct functioning of the measuring channel (s) must undergo a daily inspection.
•The wear shield made of ceramic must be examined for damage and wear
•Remove any material which adheres to the ceramic wear shield.
•An even flow of material with sufficient over-layer (>50mm) must be present.
•The moisture measuring value must be verified via a laboratory test. A sufficient quantity of material,
representative of the mix, is extracted and at the same time the moisture measuring value or the digit
value is recorded. If the deviations prove too great, the calibration curves can be adjusted. (see PC soft-
ware or indication and parameterisation module)
Replacing the sensor
Electric shock!
Connection of the plant and all tasks to the electrical equip-
ment may only be carried out by an electrical specialist.
DANGER Moving machine parts!
The sensor can be fitted in the immediate proximity of mov-
ing machine parts. Switch off the machine!
1. Cut the voltage supply to the measuring system.
2. Open the bus connection socket, loosen the cable clamp and unclamp the sensor cable.
3. First loosen the fastening (B) and then loosen the straining screw (E) until the mounting flange releases
the sensor.
4. Install a new sensor in the mounting flange, adjust. and tighten the straining screw (E).
5. Tighten the fastening (B).
6. Clamp the sensor cable, tighten the cable clamp and connect the bus connection socket.
7. Clean and dry the surface of the sensor.
8. Start up the measuring system once again
9. Read off the digit value for the air and carry out an offset. A recalibration of the measuring channel is
then not necessary. (see PC software or APM)

7. DIGISYS interchange and evaluation unit
The ACO_DIGISYS interchange and evaluation unit is comprised of a WAGO - I/O - SYSTEM 750. A de-
tailed description of all components can be obtained from the company, WAGO Kontakttechnik GmbH, Min-
den, or alternatively, from the internet site from WAGO Kontakttechnik GmbH: http://www.wago.com.
The field bus controller 750-833000-002 includes a ACO-specific Firmware, comprising the complete ACO-
DIGISYS - approach:
•Communication with overriding system (PROFIBUS)
•Issue of measured values via diverse interfaces
•Start-Stop control mean value calculator
•Distribute measuring orders
•Storage of measuring channel configuration, curves, thresh-
olds etc.
•Summarisation of measured values from several sensors
•Material curve changeover
•Error report
7.1 Measuring operation
Moisture measuring is initiated automatically following activation of the DIGISYS.
No operation is necessary in this operating mode.
This operation is not discontinued, even within the service functions, thus the measurement continues to run
in the background.
7.2 Configuration and programming interface
The configuration and programming interface is located behind the cover flap. It is
used for communication with the PC-software, the indication and parameterisation
module and for transmission of the Firmware. The communication cable is con-
nected to the 4-pin port (1).
The switch for the operation mode (2) is also located behind the cover flap. The
switch (2) is a push-slide switch featuring three positions and a key function.
Functions of the operation mode switch
Operation mode switch (2) Function
From the middle to the upper
position Activate program processing (RUN)
From the upper to the middle
position Stop program processing (STOP)
Lower position Bootstrap for booting the Firmware, not necessary for the user.
Hardware-Reset
Press down (using a screwdriver,
for example) All outputs and flags are reset; Variables are set to 0 or to FALSE or to an initial
value. The Hardware - Reset can be initiated with STOP, as well as with RUN in
each position of the operation mode switch!
A change in operation mode occurs internally at the end of a PFC-cycle.
