1.1 Product Description & Applications
The Scale Interface Box is a controller designed for use in the control of fermentation,
cell culture, and similar applications. In addition to the supplied components, this
controller requires the use of a computer with the Windows

operating system.
NOTE:
In this manual, the Scale Interface Box is referred to interchangeably
as “the box” and as “the controller”.
This controller supports eight independent control loops in applications using
BioCommand Plus supervisory software. There are eight independent input connectors at
the rear of the controller for the connection of serial signals from scales or load cells. The
controller provides users with the ability to determine the weight of any liquid added, or
the weight of the entire vessel. The functionality, further enhanced by an onboard
algorithm, is used to determine the flowrate of any addition pump, mounted on a scale,
based upon the rate at which the mass of the addition vessel changes.
NOTE:
This Scale Interface Box supports (1) Mettler Toledo scales that use the
SICS level 0 communication protocol and (2) Sartorius balances. No
other serial communications are supported.
A Windows

-based user-interface software package is supplied with the controller. A
user-supplied external computer is required to run this package. All of the tools required
to configure the controller and display the process status are provided in the interface
software.
Controller features and settings for specific applications may be user-configured with the
interface software:
•
Setpoints, alarm levels, P-I-D values (controller response characteristics) and control
modes are all user-defined and easily changed.
•
Process conditions can be displayed as virtual gauges or trend graphs.
•
Password security can protect against accidental or unauthorized process or controller
changes.
