Installation of the unit is performed exclusively in KRO. Provide a dry, lighted and ventilated room for cabinet installation.
Be sure to conduct the earth wire to KRO, along with conducting of phase and neutral wire of voltage and correctly ground automate.
It is mandatory to bring 20 ÷ 24V ac / dc as written in the declaration and on the label of unit. Pay most of attention not to
connect high alternating voltage to digital nor analog inputs.
To avoid danger of fire or electrical shock, never exposed any unit nor KRO to influence or rain, snow or humidity. KRO
cabinet is transported wrapped in stretchable, waterproof foil. If any part of the machine is damaged or there is any doubt about its
correctness, use of KRO and drying system are prohibited.
Be sure to disconnect the unit from the power supply (term.clamp 2) before installing or opening the MC-3000 . All interventions
on the unit must be performed by persons authorized for service or trained technical personnel. Necessary replacements are made to
the original spare parts. For help, information and repair services, contact an authorized servicer or manufacturer NIGOS-elektronik.
Access is banned for children and unemployed persons!
Do not install the KRO cabinet near a device that produces strong electromagnetic or mechanical interference (except for
frequency regulators, which have to be electromagnetically compatible) , as is not in the areas with exploding atmosphere.

4Automatic control unit MC-3000 (version 1.1.1)
Additional security measures for correct and safe installation of system:
The HMI panel unit and the relay board are intended for installation on the KRO cabinet in a room with operating conditions
0 ÷ 50°C, without moisture and dust.
Pay attention to installation of other equipment in the KRO in order to avoid interference from mutual influence.
Measuring--communication module MKM is mounted outside, on the rear wall of the dryer, above the auxiliary door. As it is
exposed to external influences, it is mounted under the tin cover ( “roof”).
Installation of probes is described in section 3.4. INSTALLATION OF PROBES IN DRYING CHAMBER
To connect the measuring-communication module MKM, use communication cable with a shield that must not be placed in
parallel with power cables at a distance of less than 30 cm . An intersection at a right angle would be ideal.

2. LITHIUM BATTERY REPLACEMENT IN MC-3000 PANEL
Table 2. Battery technical specifications
MC-3000 unit contains a real-time clock circuit and a button battery, which provides the
necessary energy to provide this circuit independence of external power. Despite constant
work, consumption is low and battery life is about three years. If the drying system is often
shut down, it is advised to remove 3V battery and set the time and date for the next use of the
unit. It also advises replacing the battery every 3 years to avoid miscalculations of time and
errors in the history records.
Figure 2. Remove of metal cover on rear side of unit (up) and main printed circuit board of unit with 3V battery (down)
- Pull out both terminal clamps (K1 PC and K2 KILN/BUS) from the rear side of unit.
- Remove 4 screws from the rear side (one at each corner) and remove metal cover.
- Battery is located in a battery holder on the main PCB of unit.
- Push the flat screwdriver under the battery and remove the battery from the battery holder.
- Use lithium battery CR2032 of 3V only as replacement !
- Replace the battery with the suitable one. Pay attention to the poles !
- Put the cover back on and tighten all screws.
- Connect both terminal clamps (K1 and K2) with the automatic controller unit.
- Put the battery in adequate packaging to avoid short-docking and take the battery to the recycling service.

Figure 3.2.3. Block schematics of connecting equipment of dehumidifying dryer to RB-3000 relay board
NOTE: Figures represent examples of connection of output devices, directly connected to 230 Vac power supply. The user can use
devices with different power. It is recommended that user use voltage-free contacts for work with output devices !
3.2.1. Fuse replacement of relay board RB-3000
In case that RB-3000 is connected to power supply, but POWER LED does not glow, fuse marked with POWER FUSE needs to be replaced.
In case that RB-3000 can not turn on output devices, but their LED glow, fuse marked with RELAY FUSE needs to be replaced.
- Only a trained person (electrician) can replace the fuses !
- It is mandatory to pull out clamps: K4 (power supply) and K9 (relay outputs) before any replacement !
- Insert a flat screwdriver into the slot under the FUSE sign, press it and turn it to the left for about 60°.
- The fuse carrier's loose. Pull the carrier up from RB-3000 and pull the fuse out of the carrier.
- Discard old fuse, replace it with suitable one, which is given together with RB-3000 in certain quantity.
- Use T3,15A/250V fuses only as replacement! Be sure that the same type is given with RB-3000.
- Put a new fuse in the fuse carrier and return the carrier back in the fuse case in RB-3000.
- With a flat screwdriver, press the carrier into fuse case and turn it to the right for about 60°.
- Re-connect loosed clamps back to RB-3000.
