3.4. INSTALLATION OF PROBES IN DRYING CHAMBER
3.4.1. Installation of probes for measuring equilibrium moisture content in the dryer
This probe is placed in DS-04t and RF-EMC boxes. The paper holder is made of aluminum and is mounted on it according to the instructions
given (Figure 3.4.1). The measuring sample has rectangular shape and it is made of hygroscopic paper.
Placement of EMC paper into holder: Unwind 4 nuts on the sample holder so that the springs become free. The sample is placed between 2
sets of plates. Wind up rolls tighten so that the tiles are well attached to the sample and the make contact between them.
NOTE:
This sample is used for ONLY ONE drying cycle. After each drying cycle, the paper is thrown away and renewed as written above.
In case of RF-SHT probe instead of RF-EMC, no need for papers, since built-in SHT sensor unifies temperature and EMC se.

3.4.2. Installation of probes for measuring wood moisture content
The whole process of drying sawn lumber is conducted on the basis of the measured average moisture in the wood, which was obtained from
eight measuring spots (probes). That is why it is extremely important to properly place and arrange the probes in the lumber stock. The same
stainless steel probes are used to connect to the DS-04t boxes as for the RF-MC1 probes. Sometimes it is necessary to use stainless steel
screws instead of stainless steel nails, for thin wooden materials (eg. lamellas).
The probes are made of INOX (rust-proof, stainless steel). After drying, the probes are removed with special tool and will be used for next
drying. The recommended dimensions of the nails for measuring wood MC are:
30 mm for lumber up to 40 mm thick (thinner lumber) and
45 mm for lumber over 40 mm thick (thicker lumber)

Figure 3.4.2. Proper drilling of holes and hammering of INOX probes into the lumber
One pair of probes is used for one wood MC measuring spot.
First at all, drill two holes in a wood board with Ø 3.2 drill bit (3 ÷ 3.5 mm), up to half the lumber thickness.
Further, the probes are hammered into prepared holes, where the depth of penetration must not be less than 1/3 thickness of the lumber, and it
is best to be up to 1/2 thick of lumber.
Probes are placed cross-board at a distance of 30 to 35 mm (ideally 32 mm). Thinner and softer lumber does life is minimal twonot need
drilling, but probes can be hammered directly.

A pair of stainless steel screws are used to measure the moisture in the lamella as shown in the following figure, with the recommended
dimensions of the screws 4.8 x 13 mm. The screws are placed transversely on the lamella at a distance of 30 mm to 35 mm (ideally 32 mm). .
A couple of holes are first drilled in the board with a Ø 3.2 mm drill bit. A nickel-plated ring pedal (Ø 4.8 - 1mm2) is placed on the screw as
an adapter for connecting the probe cable. Then, a rubber 3 ÷ 5 mm thick, 15 ÷ 20 mm in diameter is placed (sealing plumbing rubber rings are
used). After that, the screws are screwed into the prepared holes until the rubber is slightly sunken. With thinner and softer material, you do
not need to drill holes, but the screws are screwed directly into the material. The following figure gives an example of placing probes. After
drying, the screws have to be removed and a new pair of screws is needed for the next drying.

3.5. WIRELESS PROBE BATTERIES
Additional safety warnings for non-rechargeable batteries:
Don't open the batteries.
Do not store batteries at a temperature higher than 40 °C, do not heat them or expose them to flames.
Empty and damaged batteries store under WEEE directive and local laws.
Under extreme conditions, there may be a leak of electrolytes from the battery. In that case, wipe the battery and the interior of
probe with dry cloth, while avoiding contact with the skin.
The battery meets the standards IEC60086-4, IEC60079-11, UL1642 and directives RoHS and REACH.
Table 3.6. Battery technical specifications
Wireless probes run on batteries at all times and send measurements to MKM-RF. Despite
constant work, consumption is low and battery life is minimal two years. If the probe has not
been used for a long time, it is advised to remove the batteries from the probes. It also advises
replacing batteries every two years to avoid miscalculation results.
It is preferable to replace batteries before drying process starts, but if the battery runs out or leaks
during drying, passivise probe on controller screen. A more detailed description follows.
Disconnect RF-MC1 probe from the silicon cables or disconnect RF-EMC and RF-SHT probes
from the chamber wall. Remove a cover and replace a battery (see below for more details). Close
the cover and restore the silicone cables to the RF-MC1 probe or return RF-EMC and RF-SHT to the wall. Activate probes on MC-3000 unit
and check measures after a few minutes. Put the batteries in adequate packaging to avoid short-docking and take them to the recycling service.
3.5.1. Battery replacement in RF-MC1
- Pull out 2 silicone cables from the side of RF-
MC1.
- Remove 8 screws from the top of probe and
remove cover.
- Use a sharp tool to press the tooth in each white
battery contact holder to release the contact.
- Replace the battery with a suitable one, paying
attention to the poles, using a sharp tool.
- Return upper cover, making sure that the silicone
rubber is well fitted and that the opening on the
cover matches LED from PCB and tighten screws.
- Connect 2 silicone cables.
- Return RF-MC1 on the wood, if the battery is
changed during drying process.
3.5.2. Battery replacement in RF-EMC and RF-SHT
-Remove probe from a wall of the dryer chamber.
-Remove 4 screws on the back of the box and remove
front cover.
-Replace battery with suitable one, paying attention to the
poles.
-Return front cover, tighten the screws on the back.
-Return the probe on the wall of the dryer chamber.

3.6. CONNECTING THE COMMUNICATION LINE
The communication of the machine with a PC allows monitoring and control of the drying process via a computer. Supplied as an option at the
request of the customer.
Communication between the computer (PC) and the control unit is performed by the communication standard RS - 485. The drying process
control unit and the computer are connected with an S / FTP CAT7 cable. The length of this cable can be up to 1000 m.
This equipment is used not only to connect the machine to the computer but also to connect communication boxes, frequency regulators,
sterilization boxes, etc ... The last device on the line must have a terminating resistor between communication connections A1 and B1 or A and
B. A resistor of 120 is used Ω. The devices supplied by NIGOS-elektronik have terminals for communication with the factory-mounted
resistor. If the controller unit is connected somewhere in the middle of the cable, the resistor is removed. If the controller unit is located at the
end of the cable, the resistor must remain connected between A1 and B1.
Figure 3.6. shows the connection method where the MC-3000 unit is placed first on the master (and on the slave) line and the resistor is
removed, the next controller unit continues on it and so on. Terminal resistor lefts on the last unit.
As for grounding, it is enough to connect the shield to the ground only at one end of the cable. Cable shield connects only to the ground of the
PC (housing), and no need to connect with other devices on the line, just passes through the cable. At the cable break point, the shield is short-
circuited as shown in the cable joining scheme between the two MC-3000 units.

4. OPERATIONS OF AUTOMATIC CONTROLLER UNIT
After switching on the machine to the power supply, the software first automatically performs an internal memory check, resets the equipment
in the dryer and displays the home screen - main menu.
4.1. MAIN MENU ON PANEL OF MC-3000
The MC-3000 is equipped with a touch screen. All settings are made by a short and light touch on the field with the desired symbol or the
desired text displayed on the screen. In case of damage on the sensitive layer, the contoller can no longer be used.
From the main menu, selectables are: graphic view , textual view , history , regimes , settings and access level .

4.2. HUMIDITY CALCULATOR
Touching the field "Humidity calculator" opens new pop-up windows on the center of
main menu, as presented on figure on the left. Main function of the calculator is
conversion of psychonometric values, relative humidity and equilibrium moisture content
in the air. This can help the user to create new drying regimes or to translate older regimes
based on psychonometric measurements.
Each of the 4 sizes (dry probe temperature, wet probe temperature, relative humidity and
mixed humidity) has its own sliders to change the value. By changing one, the other
values are calculated automatically. The fifth slider, at the bottom of the window, is used
to change the temperature scale from Celsius to Fahrenheit and vice versa.
To exit the humidity calculator, touch one of the 4 visible fields of the main menu screen,
beside the calculator.
