Rice Lake 920i Bulkweigher 107 - 108 - 109 - Manual (Page 21)

Sequence of Operation for System 107 17
4.0 Sequence of Operation
While all three systems operate much the same way, there are subtle differences between their setup and in the
actual operating sequence. For that reason, this manual has been divided into three sections to address each system.
4.1 Sequence of Operation for System 107
The following instructions explain a basic setup and sequence of operation for the 920i Flexweigh Systems 107
Bulkweigher.
4.1.1 Setup
The Flexweigh Systems 107 (Shipping Mode) is designed for basic shipping mode bulkweighing applications. In
shipping mode, a scale is loaded and discharged repetitively until a desired accumulative weight is achieved. Use
the following steps to set up the operating sequence for System 107.
Note
The front panel E-Stop button must be in the stopped position (pushed in) to enable any of the following
keypad entries.
If the load-out target, fill weight, discharge weight, target weight, draft weight, empty weight, preact 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 draft weight, empty weight, preact weight, and target
weight.
3. Press one of the following softkeys and enter a desired weight value:
• Draft weight
• Empty weight
• Preact weight*
• Target weight
• Load-out target weight
• Fill weight
• Discharge weight
4. Press the Exit 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 corresponding 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.
4.1.2 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 preset 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 faults 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*.
