4.2 Sequence of Operation for System 108 (Receiving Mode)
The following instructions explain a basic sequence of operation for the 920i Flexweigh Systems 108 (Receiving
Mode operation).
4.2.1 Setup
The Flexweigh Systems 108 (Receiving Mode) is designed for basic receiving mode bulkweighing applications. In
receiving mode, a scale is loaded and discharged repetitively until there is no more product to receive. Use the fol-
lowing steps to set up the operating sequence for System 108.
Not
The front panel E-Stop button must be in the stopped position (pushed in) to enable any of the following
keypad entries:
If the fill weight, discharge weight, preact weight*, draft weight, empty weight, ID#1, or ID#2 settings need to be
changed, use the following steps.
1. Push the E-Stop button in.
2. Press the
Presets softkey to display the presets menu for fill weight, preact weight, discharge weight and over-
fill weight.
3. Press one of the following softkeys and enter a desired weight value:
• Draft weight
• Empty weight
• Discharge weight
• Fill weight
• Preact weight*
4. Press the Done softkey when finished to return to the main screen.
5. Press the ID softkey to enter the ID number setup if the IDs are to be changed.
6. To disable an ID, press the corresponding ID Off softkey.
7. To enable an ID, key in the ID number and press the proper ID On softkey.
8. To change an ID value, key in the new ID number and press the selected New ID softkey.
9. Press the Exit softkey when finished to return to the main screen.
*Preact: Preact may be selected as off, fixed, or learned. The learned preact is a design that provides some scale
overfill protection on the first draft of a cycle when the upper garner may be full and the surge of flow on the first
draft might be overwhelming. The preact value entered may be exceptionally large and is the fixed value for every
first draft that occurs after pressing
Start or after recovering from a stop by pressing Resume . On subsequent fills
during the cycle, the preact self learns and makes automatic adjustment corrections of 50% whenever the final fill
weight is more than 2% of the fill weight preset.
4.2.2 Operating Sequence
Use the following steps to run through an actual operating sequence.
1. Ensure that the E-Stop button is in the out position and Presets and ID# data entry are inhibited.
2. Press the
Start/Resume button.
3. The system checks for the following inputs to all be in initial ON state: fill gate closed, discharge gate closed,
surge hopper not full, weigh hopper not overfilled, printer online. If any inputs fail the initial start test, an
appropriate error message flashes and the sequence defaults to step 2.
4. The system clears the indicator display of the accumulated total weight and draft count remaining for view
from the previous cycle*.
5. The system prints the ticket header with the time/date and ID#1 and ID#2, if enabled.
6. The system waits for scale out of motion and captures the empty weight value*.
7. While the printer is online, the system prints the empty weight.
8. The system turns on the fill output and keeps it on until the draft preset weight has been achieved.
9. The system turns off the fill output, and pauses during delay after fill.
