17 CHAPTER 3
Filler
refill can occur at any time during the fill-
ing process. (See Fig. 3-22)
FIG. 3-22 REFILL DISPLAY
NOTE: The Autozero function is selectable and can be
turned ON or OFF. If Autozero is turned OFF
during setup, than the instrument checks for
motion and autotares the scale before filling.
FIG. 3-23 WAITING ON DISPLAY
NOTE: From this point on the filling process is automatic
and under normal conditions does not require
operator intervention. The displays provided are
to illustrate the procedures the instrument goes
through and the displays associated with these
procedures. It is highly unlikely that you will be
required to manually intervene except where the
Alarm conditions might occur. A list of the
Alarm conditions and remedies are provided after
this section.
Step 8. If the “OK to Fill” function is turned ON, in addi-
tion to the motion, autozero, and autotare, the
instrument checks to see that the system is ready to
fill. This means that the instrument can check a
proximity switch for container positioning, a sensor
detecting that a valve is open or closed, an OK to
Fill instruction sent from a PLC or DCS and so on.
• If it is OK to Fill, the Filler/Dispenser
starts filling and returns to the fill Display.
(See Fig. 3-24)
• If it is NOT OK to Fill, an alarm appears in
the display. (See List of Alarms Not OK to
Fill Alarm)
FIG. 3-24 FILL DISPLAY FAST FILL ON
NOTE: The “Fast Fill” appears for both Single or Dual
Speed Filling.
• Ingredient = flour
• Current filled amount = 9 lbs out of 225
lbs. gain in weight for cycle number 1.
• Cycle = 1 out of 56 cycles.
• Filler Status = FAST FILL ON
Step 9. When the weight reaches the Target Window, the
Filler/Dispenser goes into a wait sequence to allow
the material to settle before checking to see if the
fill weight is correct. (See Fig. 3-25)
NOTE: The Target Window is reached when the net
weight on the scale is equal to or greater than the
target weight minus the preact value.
FIG. 3-25 WAIT DISPLAY
Step 10. The Filler/Dispenser automatically checks to see if
the fill is within the target window.
• If the fill is within the target window and
you do not have the Discharge Function
turned ON (See Discharge Function
below), the instrument returns to the Wait-
ing On Display, repeats the motion check,
autozeros, autotares and/or checks the OK
to Fill processes and begins fill cycle num-
ber 2, then 3, 4 and so on. (See Fig. 3-26)
NOTE: It is important to note that if Auto Preact is ON,
the Filler/Dispenser will automatically adjust the
Ingredient Pre-Act parameter insuring that
“UNDERFILL” and “OVERFILL” conditions do
not occur. The new Pre Act value is saved for the
