GENERAL DESCRIPTION
The Legend unit (LGB) is a two input,
microprocessor-based device which features
process, batch, and total counting, as well as a time
interval rate indicator. Four presets are available,
two of which are assigned to the process counter
and the other two assignable to the batch, total or
rate indicator. The internal count precision is
maintained to 9 digits.
The RS485 serial communication port provides
for computer and printer interface that extend the
capabilities of the unit. It can be used for data
retrieval and for programming various data values.
Optional Legend Programming Software
(SFLGP) for IBM ® compatible PCs is available to
program all of the Legend configuration
parameters, such as User Inputs, Count modes, etc.
The software allows unit configurations to be
created, uploaded, downloaded, and saved to a file
for rapid programming of the Legend unit.
Application flexibility is provided through the
two-line by eight-character alphanumeric display.
The display features English language menus for
easy viewing and simplified programming. The
four scroll-through indication displays can be
programmed to show various parameters and to
automatically scroll, if desired. A program disable
DIP switch used with an external User Input can be
utilized to protect the settings and guarantee that
no unwanted changes occur during operation.
The five Programmable User Inputs can be set
for a variety of functions. Three user inputs are
located on the upper rear terminal block and the
