Rice Lake CB-2 Concrete Batch Controller Version 1.0 - Manual (Page 55)

Batching 51
8.0 Batching
There are two basic modes of operation. The simplest is a load-based approach when the operator enters only a
mix, truck, and load quantity. This method is best when the CB-2 is not used for generating billable tickets or
tracking at the order level. In contrast, if order-based loading is selected, each order is entered in the CB-2 as the
order is taken. Order information that may be entered in the CB-2 includes: Customer ID, total ordered amount,
mix design, when required, slump, delivery address, special instructions, and job IDs.
In load based batching, the
Prepare Load
softkey appears on the main menu of softkeys.
Figure 8-1. Prepare Load Softkey
Assuming that all the setup and configuration procedures have been accomplished successfully, a load can be
started by following the instructions listed below.
1. Press the
Prepare Load
softkey on the 920i display.
2. At the
Mix Design ID/Code
prompt, enter the numeric mix ID or alphanumeric code and press the
enter
key.
The mix design database is first checked for a matching mix code. If no matching mix code is found, the
mix database is searched for a matching mix ID. If neither is found, the following message appears,
Mix
ID/Code not found
, and the prompt is closed. The operator then needs to press the
Batch Load
softkey again
after figuring out the correct mix code or ID.
3. After a valid mix code or ID has been found, the operator is then prompted with
Truck #
. Enter the
number of the truck that will be loaded. The truck database is searched for a matching truck ID. If found,
the capacity, loading ratio, and driver name data are retrieved and used in the loading process. If not, the
truck number is just printed on the ticket.
4. Next, at the
Quantity
prompt, enter the load quantity. The value entered must meet the following criteria:
• The quantity must be able to fit into the selected truck as configured in the capacity field of the truck
database, provided the entered truck ID was found in the database.
• The quantity entered may be larger than the maximum plant capacity (see application parameters -
batching limits - max plant capacity setting), provided split-batching is enabled (see application
parameters - batching preferences - split batching allowed setting).
• The quantity entered must be larger than the minimum plant capacity (see application parameters -
batching limits - min. plant capacity setting).
After these three critical values have been verified, the message
Preparing...
will appear while the load and batch
calculations are being made. If no problems were encountered with the plant configuration, database data, and
calculations, the
preview load
screen is displayed.
5. Once all of these parameters are successfully entered into the CB-2 the
Preview Load
screen is displayed.
The
Preview Load
screen is automatically displayed so the user can:
• Confirm the mix design, quantity, and target values for each material in the mix.
