LGB00100 - Four Preset Batch Legend with Red Backlighting & Relay Board
Four Preset Batch Legend with Red Backlighting & Relay Board
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 other two inputs are front panel function keys.
When power is turned off, the unit automatically saves the settings and data in its no-power memory. When power is restored, the LGB restores the parameters it had at power down. The EPROM’s life expectancy is at least 100,000 power cycles. The LGB offers a choice of seven programmable counting modes for use in applications requiring Bi-directional, Anti-coincidence, and Quadrature counting. A separate inhibit terminal can be used for any of the count modes.
Input A accepts a signal for the Count (Process & Total) and Rate displays. Input B accepts a signal for the Count (Process & Total) display or direction control. In the Anti-coincidence mode both inputs are monitored simultaneously, so that no counts are lost, and the final count can be chosen as the sum or difference of the two inputs. Rate and Count (Process & Total) displays have separate scaling and decimal point placement, for the readouts in different units.
The Counter Load feature enables the operator to modify the count value under circumstances that occur when flawed material has been counted and it is necessary to adjust the count value accordingly. The rate operates in the time interval method (1/tau) to calculate the rate value. This method insures high resolution at all input 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 plug-in relay board operates with the Process counter and has two, 5 amp, 240 VAC relay outputs. The open collector outputs can be assigned to either the Batch count, Total count, or Rate indicator. The programmable outputs can be set for a variety of functions.
The construction of the Legend LGB unit is a lightweight, 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.
