MC-100RM achieves optimum conditions for wood drying
inside the chamber through air temperature and humidity control. MC-100RM
controls its relay outputs automatically, semi-automatically or user can
do it manually based on data obtained from temperature and EMC probes (in
2 points) and MC probes (obtained from 6 points). In addition, control of
drying process is adjusted according to user settings.
In automatic operation mode, MC-100RM follows
chosen drying schedule (regime). There are 12 invariable (built-in)
schedules which are inserted in unit's memory by "NIGOS"
during production and which can not be changed. User has an ability to
make its own schedules. These schedules are memorized in unit's memory,
always available and can be altered at any time. There is a pre-reserved
place in the units memory for 8 user schedules.
In semi-automatic operation mode user set the
desired values for temperature and EMC based on personal experience and
measured wood MC and automatic control unit MC-100RM only tries to
maintain this values inside the chamber.
In manual operation mode, buttons and switches
on the lower part of device are used. Switches give the user an ability to
choose manual control of heating valve, servo-controlled flaps and
sprinklers for spraying. Buttons are used to turn the equipment for which
manual mode is selected ON or OFF. These buttons have no function if other
mode is selected. While in manual operation mode, the MC-100RM unit only
displays measured values for T, EMC and MC, but it has no influence on the
relay outputs. User himself must control temperature and humidity by
pressing the appropriate buttons.
After power failure, if it was started, drying will
automatically continue when power is reconnected starting from measured
wood MC.
Automatic control unit is delivered with following
equipment included (standard configuration):
- Automatic control unit MC-100RM: 1 pcs
- Measurement unit MKM-01: 1 pcs
- Measurement boxes DS-03 with fitted temperature probes: 2 pcs
- EMC paper holder which is fitted on DS-03 box: 2 pcs
- EMC paper in quantity sufficient for 2 years drying: 1 set
- Set of wood MC probes for different wood thickness: 1 set
- Cables for boxes connection
- Tephlone cables for wood MC measurement: 8m x 6 pcs
In case of user's special request, or if it is
necessary for quality drying in specific dryer, additional equipment is
delivered. Since 1 or 2 measurement units MKM-01 can be connected to
MC-100RM unit, each with different number and type of measurement boxes
(DS-03, DS-04, D-02 and others), there is a possibility of making several
specific system configurations and achieve wood MC measurement in 8 point
maximum.
Warranty for automatic control unit MC-100RM is
5 years.
