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.

DESCRIPTION (Cont’d)

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.

The choice of several reset cycle modes along with the compatibility of count
and control inputs to other RLC products, provides added versatility for stand­alone and system counter needs.

The rate input uses the time interval method (1/tau) to calculate the rate
value. This method insures high resolution at all input rates. The unit counts
input pulses and after the programmable minimum update time elapses and the
next count edge occurs, the unit will take the number of edges that occurred
during the elapsed time to calculate the rate value. The minimum update time
can be as low as 0.1 second per update, enabling quick response to rate changes.
At slower rates, averaging can be accomplished by programming the Minimum
and Maximum Update Time for the desired response. Extensive scaling
capabilities allow practically any reading at very slow input rates.

The construction of the Legend series is a light weight high impact plastic
case with a clear viewing window. The sealed front panel with the silicone
rubber keypad meets NEMA 4X/IP65 specifications for wash-down and/or
dusty environments, when properly installed. Plug-in style terminal blocks
simplify installation and wiring change-outs.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.

Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit.

MODELS - LGS & LGD

The single preset unit has one NPN open collector output and the dual preset
unit has two outputs which are activated from presets 1 and 2 respectively. Each
output can be assigned to either Rate or Count display. An optional relay board
can be installed that operates in parallel with the solid state output(s).

MODEL - LGB

The process counter is used to monitor the progress of the count within the
batch. Presets 1 and 2 are assigned to the Process Counter and activate relay
outputs 1 and 2 respectively.

Presets 3 and 4 can be assigned to either the Batch Counter, Totalizer, or Rate
indicator. Presets 3 and 4 activate the NPN open collector outputs O3-SNK and
O4-SNK respectively.

MODEL - LGM

The Multi Preset unit has six Presets (1-6) which control NPN open collector
outputs 01-SNK to 06-SNK respectively. Preset one through four are assigned
to the count display. Presets 5 and 6 can be assigned to either the Rate or Count
display.

PROGRAMMING

The Legend Series provides an easy to use, menu driven programming

interface. The English prompts, the front panel keypad, and the flashing display
aids the operator during programming. In the normal run mode, the main
display loop allows the user to scroll through the four programmable indication
displays, using the direction keys. From the main loop, presets and scale factors
can be accessed directly for changing parameters. All other parameters are
accessed through the programming loop. In the programming loop, parameters
can be viewed or changed and the operator can exit anywhere in the loop.
Shown to the side is part of the main display loop and part of the programming
loop of a Dual Preset Legend (LGD) unit. Also shown are four different views
of the indication displays.
