To enabled Precision Ratio press (*,8,2).
Pressing the CE key will toggle between:
PRECISION RATIOING DISABLED, PRECISION RATIOING
COLOR, PRECISION RATIOING ADDITIVE . Only one component (Color or Additive) 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.
When finished, press Exit to save changes, then press Exit again to exit out of Programming Mode.
Backdoor Password
Press (*,8,6) to select a new "Back Door" password for your software. Display will say BACKDOOR
PASSWORD Select (0-9): 00000 . Enter 00001 up to 00009 to select one of nine new backdoor
passwords. Contact us for the actual number. If you just want to kill the use of a backdoor password
altogether, just enter a number from 1 to 9, and don't call us. Then no one in you plant will know the
number. But we still will, just in case. Then your own selected regular password will work and as long as
you don't forget it, your ok.
Blenders are pre-programmed with two normal passwords; (22222) is the default password for the
PROGRAM mode, (11111) is the default password for the MANUAL mode. You can alter these passwords
to any 5 digit number, but you must know the current PROGRAM password to change it. If for some
reason the password has been altered and you can not remember it, we have a special "backdoor"
password that will let you in no matter what. For obvious reasons, we do not provide that password in this
manual. You must call us. However, there is a problem. If the wrong person in your factory obtains this
password, then he will always have access to the Program mode of the blender no matter what.
Now, with this star function, you have the option to select from 10 different "backdoor" passwords. If your
current "backdoor" password is known to the wrong person, you can call us for a new one. We will not give
these backup passwords to just anyone. In fact, since only I know them, it is not that easy to obtain these
numbers.
