3.3 Conveyer furnaces DTC CONFIGURATION All Conveyor Furnaces require the Controller Unit and either the Program and Display Unit or the Touch Screen Display . The difference in configuration depends on the heated length (number of control zones) and the width of the zones (whether or not side zone control is used). This will not only affect the number of boards in the Controller Unit, but also the type of Output Expander Unit used and the number of boards therein. If zones 13, 14 and 15 are not used as control zones, they can be used for profiling or temperature measurement. 3.3.1 Small band conveyors The system configuration is solely dependent on the number of control zones used: a) For 1 to 6 Control Zones The system will consist of the Controller Unit and the Program and Display Unit or the Touch Screen Display , containing one or two, 3 channel input boards and one or two, 3 channel output boards. The number of input boards will be the same as the number of output boards. For example: To control 2 zones, one input board and one output board is necessary. b) For more than 6 Control Zones Besides the Controller Unit fitted with an Output Expander Interconnection board and the Program and Display Unit or the Touch Screen Display. An Output Expander Unit A has to be added to the configuration. The Controller Unit will contain the appropriate number of input boards (1 board for every 3 control zones) and an Output Expander Interconnection board placed in the first output board slot. The Output Expander Unit A will contain between 3 and 5 output boards depending on the number of control zones. There must be the same number of input and output boards. 3.3.2 Broadband conveyors For the broadband conveyors or small band conveyors with accurate crossbelt temperature control, gain control on the two side zones is needed. The system requires the Controller Unit fitted with an Output Expander Interconnection board and either the Program and Display Unit or the Touch Screen Display;, and the Output Expander Unit B. The differences in configuration stem from the number of control zones used. a) For 1 to 9 Control Zones The Controller Unit is fitted with one to three input boards (1 board for every 3 control zones). Output Expander Unit B contains an output board for each zone, which triggers the main zone and it's 2 side zones. b) For more than 9 Zones The Controller Unit is fitted with four or five input boards (1 board for every 3 control zones). Output Expander Unit B contains the maximum nine output boards. It is, therefore, necessary that Output Expander Unit C is used, containing one board for each zone greater than nine.
