MC-1000/MC-1000P automatic control
unit for wood dryers is a device intended for drying process control in conventional (steam) dryers
and dehumidifying dryers produced by “NIGOS – elektronik”. It is
produced in 2 models. MC-1000 is fitted in plastic case suitable
for wall mounting, while model MC-1000P is produced in aluminum
housing which must be installed in electric board.
Model
MC-1000P is panel version of the controller. It is delivered
already installed in power electric switch board. User connects
equipment in the chamber to appropriate clamps in the switch
board.
MC-1000 set consist of 2 parts: automatic control
unit MC-1000 and relay box RK-08 which are connected together,
but if required, can be delivered and installed separately.
Cable glands for command and communication cables are fitted
on bottom part of MC-1000. Alarm, digital and analogue
inputs and communication with PC, MKM-08 and RK-08 are connected
to MC-1000. Power supply and equipment in the chamber (fans,
dampers, valves, compressor, etc...) are connected to RK-08A.
Additional cable glands are installed when necessary.
Front cover of the controller is transparent and can be opened
when controller adjustment is required. Picture on the
right shows connection of controller MC-1000 with MKM-08 and
DS-04 boxes. |

MC-1000 receives information about temperature and humidity from the
measurement module MKM-08 via communication line. Temperature and
Equilibrium Moisture Content (EMC) are measured at 2 measurement points
and wood moisture content (MC) at 8 points. Measurement module MKM-08
receives these data from 2 measurement boxes DS-04, transforms them and
then transfers the data to MC-1000 controller. Controller controls the
drying process based on these data.
It can operate in automatic
or semi-automatic mode, depending on settings made by user. When in
automatic control mode, MC–1000 follows the chosen drying regime and
achieves optimal drying conditions in the kiln automatically. Automatic
control is carried out through the unit’s relay outputs. In
semiautomatic control mode, user can set desired setpoints for air
temperature and humidity, based on the personal experience, and the unit
only maintains those values inside the kiln at the desired point.
The unit can be connected to a PC, which enables control of drying
process from distance (from the office or suitable operating room).
Additional capability of the MC-1000 controller is manual control of
the drying process. User can use switches and buttons, placed on the
relay box RK-08A, for manual control of relay outputs. During this time
the controller only displays the measured values.
In all other
cases, the MC-1000 controls relay outputs automatically. All output
adjustments are built-in, so the user has no influence on their
operation during drying process. Most irregular situations that may
occur are registered and resolved within the controller's program
options. User intervention is required in certain situations that cannot
be resolved by controller, or in case of unknown conditions.
Main
feature which makes MC-1000 different than other controllers is built in
program for thermal treatment of the wood, i.e.. wood sterilization
according to ISPM-15 standard. Sterilization is a thermal process which
is used to disinfect wood. Temperature of 56°C and above must be
measured in timber core for 30 minutes for successful sterilization.
Verification of the process is possible when measurement box MKM-08 is
connected to MC-1000 and PC computer. Specially designed software for
process surveillance and verification is used to verify and print report
for each sterilization batch.
MC-1000 is delivered with following
equipment (standard configuration):
- Automatic control unit MC-1000/MC-1000P: 1 unit
- Measurement box MKM-08: 1 unit
- Measurement boxes DS-04 with built in temperature probes (Pt1000): 2
units
