Mixer Control
MIX Change this to run the mixer for a longer timed period
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.
MPO For Micro Blender air driven reciprocating mixer.
MPO sets the timing, in tenths of seconds the clockwise and counterclockwise timing of the mix
blade. MPO 00010 is 1 second for each direction.
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 5
th
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 voltage to open the valve. With this flag set the computer puts out a
voltage to close the valve. For this reverse logic to work correctly, you must reverse the air lines to
the flow control valve air cylinder.
