Expansion Comm Bd
Some Genetix controllers are provided with an auxiliary communications card (also
called a “daughter card”) that is plugged into the expansion header on the GCM.
This provides for certain special serial communications features, such as
Bluetooth.
If you have such a card, this feature must be turned on to enable it.
Use Head Load
This is a feature that allows the translation of the belt load from the suspension
(where it is actually measured) to the head pulley (where it is actually discharged).
In some applications, such as Stopped Belt Batching, this can have a very
important affect on accuracy.
Note: you must enter the distance from the suspension to the head pulley (see
Main Menu > Advanced Setup > Load Cells > Numeric Data > LC to Head Pulley)
for the Genetix to know how to make this translation. This menu item will appear if
this feature is enabled.
To take advantage of Head Load translation, this feature must be enabled.
Disable Outs in Cal
This option disables the external totalizer and the analog feedrate outputs while a
Calibration procedure is running. This prevents other process equipment from
being affected by the data that would otherwise be presented at these outputs.
To enable this feature (disable the outputs), turn this feature on.
Infeed Flow Monitor
Some feeder are equipped with a device that monitors the flow in the pipe or chute
at the inlet to the feeder. Often this is an Acoustic Flow Monitor that actually listens
for this flow and sets an output when it stops, for example if the material in the silo
forms a bridge or an arch. By connecting this output directly to a Genetix digital
input certain operations can be made to automatically take place when a loss of
flow occurs. This can be very important, for example on a pressurized coal feeder
that must maintain a column of material in the infeed to form a seal. Loss of this
seal can allow hot gases into the silo and cause a fire.
To take advantage of this functionality, this feature must be enabled.
Drive Feedback
In a typical belt feeder application the Genetix controller is connected to the
variable speed drive which allows it to control the belt speed. The minimum
number of signals that must be used for this connection is an analog signal that
tells the drive how fast to go (called “Belt Speed Demand”) and a digital signal that
