FC Kiln Control System

The following is a short description of a typical kiln control system. Our kiln controls are customized to meet the requirements of any kiln. We customize our software to meet your demands.

 

FC Controller (FCC) - Main Features

      Automatic shutdown according to lumber MC not schedule time

      Up to 48 Isolated Digital Temperatures per Kiln

      Single FCC controls up to 5 kilns

      Single PC communicates with up to 4 FCCs

      Triple Processor Computer System

      Battery Back Up and Real Time Clock

      Power Fail Monitor and Watchdog Timer

      Independent from PC - Kiln keeps drying when PC hangs up!

      RS232 communication to PC

      RS232 communication to Allen Bradley PLC

-80 inputs, 32 outputs, and 32 analog outputs

Each cabinet is customized depending on the customers needs

The FC Controller, using an industrial microprocessor (Z80), provides the main process control. An Allen/Bradley SLC/503 is the basic PLC option to handle the kiln I/O and is installed in its own panel or in the kilns MCC. The customer has the option to upgrade to an A/B PLC5 in place of the A/B SLC. All I/Os in the FC Kiln Control System are handled by the PLC, except the (DTS) Digital Temperature Sensors.

The DTS is an accurate and reliable temperature source. The DTS has a physical appearance like an RTD probe, but the difference is the digital process. The DTS provides an accurate reading for consistent controlling, compared to an RTD probe, which measures temperature by resistance and often fluctuates due to wire connection faults from the humid kiln environment.

An IBM desktop computer acts as a user command center and offers an easy to use graphical interface. Some features of the control center are trending, report generation and historical databases. The IBM compatible computer is provided with an un-interruptible power supply (Smart UPS) to prevent data loss or file corruption in the event of power failure.

The complete FC Kiln Control System provides a fully automatic dynamic process-drying mode. The operator has an option to dry lumber in a static schedule-mode although optimum-drying quality is achieved when the operator uses and maintains the process-drying mode. In this mode the control will remove the free water from the lumber in the fastest time physically possible without damaging the lumber. The dynamic process-drying mode will increase lumber grade quality, while reducing the amount of energy required for drying.
