you wish to restrict use of this mode to only yourself, you may make up your own number and

Precision Ratioing - Additives
With Precision Ratioing, natural dispenses occur after the selected additive dispense or the selected
additive is introduced in between the natural component. With *82 enabled, natural is calculated to assure
the most exact percentage ratio for the smaller selected precision component. Because the Natural
dispenses are larger, this method allows for more exact ratio of the one selected precision component.
To enabled Precision Ratio press (*,8,2).
Pressing the CE key will toggle between:
PRECISION RATIOING DISABLED, PRECISION RATIOING
COMPONENT 1-12 (additives) . Only one Additive component can be selected for Precision Ratio. With
Precision Ratioing enabled on a specific component, press the * key to change the LAYERING options
then press CE to toggle to change the LAYERING option . Layering options are LAYERING (default) or
STANDARD . LAYERING will dispense ½ of the NATURAL first then the ADDITIVE, and then the 2
nd
half
of the NATURAL. This option is designed for application such as liquid color creating better dispersion and
a lesser chance of the liquid color adhering to the weigh bin while still offering more precise ratioing of the
selected additive.
STANDARD Layering will dispense the specified additive BEFORE the Naturals, instead
of after.
When finished, press Exit to save changes, then press Exit again to exit out of
Programming Mode.
Progressive Metering
Press (*,8,3) to select "Progressive Metering" option. Progressive Metering allows for more accurate
dispenses of selected components. However, cycle time will be extended by a few additional seconds.
In normal operation blenders target a dispense of the full requested amount in one try. This almost always
works, and generally will fall within acceptable upper and lower error limits. Making the dispense in one try
allows for high throughput rates while still achieving a level of accuracy acceptable for most processors.
When the accuracy of one particular component is critical, or the process depends on maintaining a tighter
tolerance of this component, customers may lengthen the blend cycle time slightly to achieve this higher
level of accuracy.
The *83 function is used to turn on the progressive metering function for a selected component. This sets
parameters which will cause the dispense to occur in several progressively smaller dispenses. This results
in a more accurate dispense.
The first dispense targets only 85 percent (the default percentage) of the full required amount. After careful
weighing, each successive dispense targets 50 percent of the remaining shortage. This continues until the
amount reaches, or is within 1 percent of, the target. In this manner the software "sneaks up" on the target,
providing the maximum achievable accuracy possible.
When a component is selected and turned ON, the corresponding PT and RP parameters are set to PT
00085 and RP 00001.
The keypad sequence:
Press *,8,3. Display will say <instruction 83> COMP: 1T.
Use the "*" key to walk through all the components.
Use the "CE" key to toggle a component ON or OFF.
When ON, Display will say
COMP: # T: 85
You may change the 85 by entering a different number. Too low a setting will just add time. Too high will
cause occasional overshooting.
Press EXIT when done to save new settings.
Backdoor Password
Press (*,8,6) to select a new "Back Door" password for your controller. Display will say
BACKDOOR
PASSWORD Select (0-9): 00000 . Enter 00000 through 00009 to select one of ten backdoor passwords.
Backdoor passwords are not published, and you must contact Maguire Products for the actual number.
Blenders are pre-programmed with two default passwords; (22222) is the default password for the
PROGRAM mode, and (11111) is the default password for the MANUAL mode. You can alter these
passwords to any 5-digit number. Also see *78.
