Application Examples
Drum Filling Application Utilizing Two Relay Outputs
In this drum filling application, the Laureate pulse-
input batch controller utilizes uses its two relays to
control a pump. The Prewarn relay slows down the
pump near the preset to avoid overshoot. The Batch
relay stops the pump at the preset.
Controlling Chemical Mixing of Materials
Multiple Laureate batch controllers can be used
in combination to control the mixing of materials in
the proper ratio. Each feed line is equipped with its
own pump, flowmeter, and Laureate.
Controller setup and monitoring of the mixing
operation are facilitated by optional serial com-
munications. RS-485 allows a single data line to
handle multiple controllers.
Up-Counting & Down-Counting Batch Control
In up-counting batch control, the Laureate counts up
from zero to a preset maximum. A prewarn level is
available to slow down filling near the preset to
avoid overshoot. A time delay can be programmed
from the end of each batch to the start of the next
batch.
In down-counting batch control, the Laureate counts
down from the preset maximum to zero. A prewarn
level is available to slow down filling or emptying
near zero. Again, a time delay can be programmed
from the end of each batch to the start of the next
batch.
Discrete Filling and Batch Counting
The Laureate batch controller is ideal for discrete
manufacturing as well as repetitive fill operations. In
this example, the Laureate counts bottles which it
then groups into sixpacks. Its Grand Total capability
can be used to track bottles or sixpacks.
