Fully automatic control system in microprocessor technology An intelligent and progressive solution for fully and semi-automatic control both of conventional and dehumidification-type timber drying kilns. The outstanding features of this proven dryer control system are its versatility, its unsurpassed procedure of controlling kiln-drying timber as dictated by the drying behaviour of the wood, its compact design, its very simple operation, and its competitive price. Control Proportional and ON-OFF control selectable for the heating system and the venting according to the individual requirements. Control of humidification selectable for steam or water spraying. The software contains proven drying schedules for over 250 species of wood and for timber thickness from 20 mm to 140 mm. Control of the drying cycle can be governed by reading of any of the available wood moisture measuring points, or by the peak or average value of the selected measuring points. Standard Equipment • Illuminated 4-line LCD matrix readout. • 16-key membrane keypad. • Control cabinet with lockable glazed front door. • Separate signal amplifier casing for easy installation of the control cabinet away from the drying kiln in a control room or the operator's office. • 4 wood-moisture and one each EMC and temperature measuring point. • Manual control of all final control elements via keypad inputs possible in case of need. Optional Equipment • Package of four additional wood-moisture measuring points. • Supplementary equipment for reversing type dryers, with the option to set fan reversal interval via keypad input. • Interface for connection of a matrix printer. • Interface for centralisation together with other computerized GANN controllers. • Variable fan-speed control if the dryer has been equipped with a frequency converter. • Supplementary equipment with up to four additional wood temperature measuring points for control and documentation of heat treatment of timber designed for packing purposes.
