Hardy HI 3010 Filler/Dispenser Controller - Manual (Page 50)

37 CHAPTER 4
Operating Procedures/Dispenser
Auto Refill ON - The configuration is the same with a Refill
High set point and Refill Low set point. The Refill Low set
point is based on the required dispense weight. However the
Dispenser checks the Refill level before each cycle and if
there is not enough material it refills to the Refill High set
point for the ingredient selected.
• If the Auto Refill function is turned ON,
the instrument begins checking to see if
there is enough material in the vessel for
the current cycle. The Auto Refill is user
selectable. For configuration information
see the HI 3010 Service Manual for
instructions.
• If the material in the vessel is below the
high level mark or is not equal to the target
weight for this ingredient, the instrument
begins the refill sub-routine.
1. The Refill On display appears. Unlike
the Filler, the refill function is only
activated at the beginning of a cycle.
(See Fig. 4-23)
FIG. 4-23 REFILL ON DISPLAY
2. Refill begins.
3. When the Refill reaches the high level
mark it shuts off.
4. Press the Start button. The dispense is
restarted
NOTE: From this point on the dispensing process is auto-
matic and under normal conditions does not
require operator intervention. The displays pro-
vided are to illustrate the procedures the instru-
ment goes through and the displays associated
with these procedures. It is highly unlikely that
you will be required to manually intervene except
when an Alarm condition occurs. A list of the
Alarm conditions and remedies are provided after
this section.
Step 8. If the “OK to Dispense” function is turned ON, in
addition to the motion and autotare, the instrument
checks to see that the system is ready to dispense.
This means that the instrument can check a proxim-
ity switch for container positioning, a sensor detect-
ing that a valve is open or closed, an OK to
Dispense instruction sent from a PLC or DCS and
so on.
• If it is OK to Dispense, the Filler/Dis-
penser starts dispensing and returns to the
Dispense Display. (See Fig. 4-24)
NOTE: The “Fast Dispense” appears for both Single or
Dual Speed Dispensing.
• Ingredient = Berries
• Current dispensed amount = 0.00 lbs out
of 20 lbs. loss in weight for cycle number
1.
• Cycle = 1 out of 23 cycles.
• Dispenser Status = FAST DISPENSE ON

Step 9. When the net weight on the scale is equal to or
greater than the target weight minus its preact
value, the Filler/Dispenser goes into a wait
sequence to allow the things to settle before check-
ing to see if the dispensed (loss-in-weight) material
is correct. (See Fig. 4-25)
FIG. 4-25 DISPENSE WAIT TIMER DISPLAY
Step 10. The Filler/Dispenser automatically checks to see if
the dispense is within the target window.
• If the dispense is within the target window
and you do not have the Discharge Func-
tion turned ON (See Discharge Function
below), the instrument returns to the
Standby Display, repeats the motion
check, autotares and/or checks the OK to
Dispense processes and begins to dispense
cycle number 2, then 3, 4 and so on.
