MIX indicates the TIME that the mixer will run after the weigh bin
dump valve opens. The number is the mix time in seconds. Adequate
mixing can be accomplished in a short time. Additional mixing may
cause separation and may create a static problem with the material.
The default value is (00015), allowing an initial mix time of 15
seconds. A maximum setting of 29999 is possible, for a mix time of
over 8 hours. Setting the mix time to 99 (MIX 00099) will cause the
mixer to run 360 seconds (6 minutes).

JOG
JOG indicates the number of times the blade will jog after initial
mixing is ended, plus the time interval between these jogs.
After mix TIME is complete, the mix blade is jogged about 1 turn
every 1/2 minute. These jogs serve to level the pile of material in
the mix chamber, insuring that the sensor does not remain covered for
too long. The first 3 digits (030xx) of the parameter indicate how
many jogs will occur. The last two digits (xxx30) indicate the
frequency (or interval) in seconds.
The default setting of (03030) produces a jog every 1/2 minute for
up to 30 jogs. You may lengthen or shorten these numbers as required.
A maximum setting of (29999) produces a maximum jog time of over 8
hours.

FCV (Delays opening and closing of the flow control valve)
FCV controls three different items:
1) Digit 1 can reverse the output logic of the computer.
2) Digits 2 and 3 set the time delay before closing.
3) Digits 4 and 5 set the time delay before opening.
The most important and primary use of FCV is to set the TIME, in
seconds, that the flow control valve delays before opening (4th and 5th
digits (FCV 000xx). If your unit is equipped with a Flow Control
Valve, under the mix chamber, it is programmed to open whenever the
sensor is covered. It will close again immediately when the sensor is
uncovered. This assures that material has time to mix before dropping
into a bin below. When a batch is dropped into the mix chamber the
sensor is covered. To prevent unmixed material from dropping
immediately out the bottom, the mix valve is delayed for a time to
allow mixing to occur first. This parameter controls the time that the
Mix Chamber Valve remains closed after a batch has been dropped.
The primary function of the valve is to assure mixing. As such it
seems best to keep as high a level as possible in the mix chamber.
However, if the chamber gets too full (over the blades), mixing is not
as good. To allow the chamber to empty to a lower level after the
sensor is uncovered, we can also DELAY the CLOSING of the flow control
valve. This is done by using the 2nd and 3rd digits (FCV 0xx00) to
specify a delay time. (FCV 00206) delays closing by 2 seconds.
If the first digit is set to a 1 (FCV 10006), the signal output to
the air solenoid is reversed. Normally, the computer puts out a
