The 2-Speed Control Scheme
In the 2-speed control scheme, you enter the following parameters:
• The low metering roll speed
• The high metering roll speed
• The grain temperature setpoint
As shown in the figure that follows, the metering rolls turn at the high speed setting if the grain temperature
is 1°F (0.56°C) above its setpoint, or they run at the low speed setting if the grain temperature is 1°F (0.56°
C) below its setpoint. The 2-speed temperature control scheme is a precursor to the more comprehensive
5-speed schemes in continuous flow. See
Setting the 2-Speed Temperature Scheme in Continuous Flow,
page 59 for details on how to set up this control scheme.
