LEGEND SERIES
MODEL LGS -Single Preset Counter/Rate Indicator
MODEL LGD - Dual Preset Counter/Rate Indicator
MODEL LGB - Four Preset Batch/Counter/Rate Indicator
MODEL LGM - Six Preset Counter/Rate Indicator
DESCRIPTION
The Legend Series consist of four different models that are multi-function
count and rate indicators. There can be up to six presets and six programmable
outputs depending upon the unit. The count and rate displays have separate
programmable decimal point settings. The unit also has rate peak and valley
displays that show the highest and lowest rate readings since they were reset
(peak and valley readings are not retained when power is removed). There are
five Programmable User Inputs, three external remote inputs and two front
panel function keys, which allow the user to select from a variety of functions.
The two line by eight character alphanumeric display with English menus,
allows for easy viewing and simple programming of the units. The four scroll
through indication displays can be programmed to show other parameters and if
desired, automatically scroll at one of the two programmable rates. 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 standard RS485 serial communication feature provides the capability of
two-way communication between the Legend unit and other compatible
equipment such as a printer, a programmable controller, or a host computer.
The Baud Rate is programmable and ranges from 1200 to 9600. The unit
address number can be programmed from 00-99. Up to thirty-two units can be
installed on a single pair of wires, each with an individual address. The Count
value(s), Preset(s), Rate, Peak, Valley, etc can all be interrogated or changed.
The output(s), counters(s), rate and peak readings can be reset, by sending the
proper command codes via serial communications or by activating a
programmable user input. When a user input, selected for the print request
function, is activated, the values specified in the Program Print Options module
can be transmitted to a printer.
Optional Programming Software (SFLGP) for IBM
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.
The Legend offers a choice of seven programmable counting modes for use
in applications requiring Bi-directional, Anti-coincidence, and Quadrature
counting. A separate external inhibit terminal can be used in conjunction with
any of the count modes. The input circuitry is switch selectable to accept signals
from a variety of input sources. A unit may be programmed to register counts on
both edges of the input signal providing frequency doubling capability.
A Legend unit will indicate an overflow condition when the capacity of a
Count display (Process, Batch, or Total) is exceeded, by flashing the word
"OVERFLOW" in the appropriate display.
All count values and program setting are retained when unit power is
removed in nonvolatile memory.
