"STANDARD INPUT" 4000 Series models are preconfigured at the factory, prior to shipment, to perform general measurement and display functions.  They let the user control basic instrument setup and operation solely by means of the six front-panel push buttons.  

NO FURTHER PROGRAMMING OF A "STANDARD INPUT" INSTRUMENT IS NORMALLY REQUIRED—except, in some cases, for specification of input range and a few other essential parameters (see the "standard configuration" to which each standard input model is initially set*).

Every standard 4000 Series instrument can be rapidly and easily reprogrammed in the field, to provide a variety of unique application solutions.  Such reprogramming is accomplished by issuing simple English mnemonic commands to the instrument.  This may be done either via an external computer or terminal, using Daytronic's convenient StartPAC 100 software, or via an optional Model 10P80D Extended Keyboard that plugs directly into the rear of the 4000 instrument.  A System Instruction Manual is available for users interested in advanced instrument programming.

The third and forth digits of a 4000 Series instrument's model number identify the "type" of signal source and, in a few cases, the number of allowed inputs, as follows:

[Back ]

	"10" = Type B, E, J, K, R, S, or T Thermocouple (up to four inputs)
	"30" or "32" = AC LVDT (one or two inputs)
	"40" = Frequency (AC or pulse input signal) (one input)
	"60" = Miscellaneous DC/AC Analog Voltage (one input)
	"62" = Miscellaneous DC Analog Voltage (one or two inputs)
	"77" = DC-Excited Strain Gage Transducer (one input)
	"78" = AC-Excited Strain Gage Transducer (one input

"SPECIAL FUNCTION" 4000 Series models are preconfigured for specific measurement and control tasks.  These models include

	transducer-dedicated "4K/SPC" Statistical Process Control Instruments
	the Model 4K/HP Horsepower Instrument
	the Model 4K/WT-77 Industrial Weighing Instrument
	the Model 4K/PM-77 Peak Monitor

"CUSTOM" 4000 Series models can also be ordered.  These instruments are fully preconfigured by our Customer Service Department on the basis of your specific application requirements.

The following 4000 Series options apply to all standard input models except the Models 4010, 4040, 4078, and 4K/HP:

	RS485 (network) data communications (a standard feature of all "4K/SPC" models)
	DC-powered (vehicle) operation)

A 4000 instrument's internal scan cycle typically produces 1000 finished engineering-unit answers per second (this includes linearization, "y = mx + b" scaling, limit comparison, cross-channel calculations, and other numeric processes).  16-bit A/D resolution with multipole per-channel analog filtering and selectable per-channel digital filtering yields rock-solid stability and a typical overall accuracy of 0.02%, following calibration by the user (see Specifications).

A number of calibration techniques are available, including "absolute," "actual" or "simulated" two-point ("deadweight"), and "calculated."  The best calibration method to employ will depend both on the conditioner model and on known characteristics of the measured test or process.

A nonlinear input (such as that produced by an LVDT or Eddy-current proximity sensor) can be calibrated by using one of the instrument's eight internal "look-up" tables.  By entering a zero point and up to 15 subsequent linearization points, you can easily define the ideal linear output for the channel in question.

For batch weighing and other applications that require auto-taring, and appropriate offset value can be automatically applied at the touch of a button, by external command.

The 4000 front panel has been carefully designed for optimum readability and visual annunciation.  The large, backlit LCD DIGITAL DISPLAY is enhanced by a 51-segment ANALOG BARGRAPH, scalable by the user.  The LCD can be adjusted for the user's particular viewing angle via front-panel buttons.

The digital and analog displays may each be independently set to represent a selected channel's current "live" data, or the "maximum" or "minimum" value detected since the last "peak reset."  In addition, the bargraph can be converted to a "needle" (single segment) indicator, or can be easily programmed to represent a number of useful values, including absolute "max minus min."

Shown in the diagram below, there are two DUAL-LIMIT DISPLAYS immediately above the bargraph—one to indicate upper and lower "CAUTION" zones (yellow), and other to indicate upper and lower "DANGER" zones (red).

Along with the bargraph, these displays let the operator see immediately which of seven distinct limit zones the current data reading occupies (there are six "VIOLATION" zones and one "SAFETY" zone).  Any one limit violation or logical combination of multiple violations can be made to trigger an isolated TTL-level logic control output or the automatic execution of one of more 4000 Series mnemonic commands—including flashing of the digital display.  See, for example, the use of the Model 4030 in Dimensional Classification of Parts.

In the "standard configuration" of each "standard input" model, some or all of the unit's eight negative-true TTL-level LOGIC I/O PORTS (shown in the rear-panel diagrams below) are initially dedicated to specific limit-triggered control outputs.  As such, they can be used to actuate solenoid valves, illuminate panel displays, sound alarms, start and stop motors or pumps, initiate and control safety shut-down sequences, and perform many other automation tasks that require "intelligent" switching, even of substantial amounts of power.  See, for example, the Model 4077's complex logic-controlled operations involved in the Automatic Sorting of Springs.

Logic I/O ports can be easily reprogrammed, if desired, for a number of useful input functions, such as "reset max/min," "auto zero," "lock data," and "print enable."

Every user-specified limit value may be either fixed (constant-valued) or continuously equal to the current reading of another data channel.  The latter feature allows continuous comparison of individual channels.

A user-scalable ±10 VDC ANALOG OUTPUT is generated for strip-chart recording, input to other systems, or general-purpose signal monitoring.  The analog output can also be used as feedback for a PID control loop.  See Specifications for full output characteristics.

Special channels can be set up to represent standard mathematical functions of one or more other channels—including absolute value and square root.  Such "CALCULATE" channels permit real-time computation and display of process variables like Efficiency, Horsepower, Specific Fuel Consumption, and Power Factor.

Other special channels can be set up for

	downloading fixed numeric values to the 4000 instrument
	creating shift registers and "block" transfers of data (also allows remote control of limit values, gains, etc.)
	automatic incremental or decremental counting of process events
	representing the maximum or minimum value experienced by a given data channel since the last "peak reset"

Each 4000 instrument lets you load, in advance, up to 16 different sequences of standard mnemonic commands.  Each command sequence will be executed immediately and automatically on detection of a predefined internal logic event—specifically, on detection of predefined LIMIT CONDITIONS or upon receipt of an externally sourced LOGIC INPUT.

Automatic "EXECUTE" functions let you set up any number of process-interactive control strategies (see, for example, how the Model 4077 uses internal "calculates" and "executes" in the Leak Testing of Hydraulic Hoses).  In response to a specific process condition or event, a 4000 instrument can, for example,

	send a prespecified warning message to the supervisory computer
	activate multiple logic outputs in a given pattern—including BINARY, BINARY CODED DECIMAL (BCD), and HEXADECIMAL
	redefine limit setpoints "on the fly" for ramp-soak operations
	rescale the analog output or switch it to a difference source channel
	"lock" or "unlock" specific measured or calculated data values

You can also customize any of the first five FRONT-PANEL BUTTONS, so that one or a sequence of standard commands are executed whenever the button is turned either ON or OFF.

The 4000 unit's front-panel buttons greatly simplify the basic setup procedure.  Provided that a SECURITY CODE (SCD) command is not in effect, they let the operator quickly review in sequence the existing numeric "configuration parameters" of a selected channel (and of the instrument itself).  At the same time, any displayed parameter may be reset to any allowable value.  All setup values are automatically stored in battery-backed memory, for complete poweroff protection.

Many users "program" their own unique and imaginative 4000 instrument configurations from the basic repertoire of functions outlines on this page.  Often the developer of an application-specific configuration will wish to protect this configuration from deliberate or inadvertent alteration and/or "cloning."  All 4000 models except the 4010, 4040, 4078, and 4K/HP now have the ability to protect the current instrument configuration from both interrogation and modification.  By specifying a unique password, the programmer in effect disables the instrument's standard responses to almost all mnemonic command issued by an external command source (optional keyboard, computer, or terminal).

Single-Node (RS232) Communications

Each 4000 instrument's 9-pin Computer Interface Port permits full-handshake RS232 data interchanges of up to 153.6K baud with a host computer, PLC, printer, recorder, or other RS232 device.  In this mode of operation, a supervisory computer can control the unit completely via simple ASCII mnemonic commands.

Depending on the application requirements, a 4000 instrument can be commanded by the operator or computer to output data from its Interface Port for one, all, or a selected range of channels, as retrieved from the instrument's continuously updated DATA RAM.

Time-coherent data "snapshot" transmissions are possible when you need to eliminate time skew within a data set.  In this case, all or selected data values remain frozen until the transfer is complete.

An intertransmission delay of up to 0.1 second can be invoked to avoid overrunning the computer input buffer when full handshake protocols are not observed.  Any user-entered "message" of up to 32 ASCII characters can also be transmitted on command from the Interface Port.  Optional output formatting includes columns, channel-number "echo," and channel limit-zone indication.

Single-node IEEE-488 or RS422 communications are made possible by an optional interface adaptor (Model CIF488A or Model 10E422, respectively).

Multinode (RS485 Network) Communications

When a 4000 unit is equipped with the "N" Option, its Interface Port can be configured for either "single-node" (RS232) or "multinode" (RS485) communications.

In multinode operation, the 4000 instrument can be a member of a high-speed multidrop network of up to 99 3500 Series and "N"-Option 4000 Series data-collection instruments, mixed as desired.  For an example of a plant-wide 4000 network, see Monitoring the pH Levels of Remotely Stored Liquids.

Network interchanges take place over simple twisted-pair RS485 "daisy-chain" linkage, at standard baud rates from 300 through 153.6K.

In a multinode network like the one shown above, the host computer can "open" any selected node by issuing an OPEN (OPN) command to the entire network.  Only one node can be "open" at any one time.  The currently "open" node (only) will respond to all subsequent commands issued to the network—including all requests for "local" measured and/or calculated data.

Simple polling routines let your computer optimize network transfer speed as it interrogates a sequence of nodes and receives appropriate response inputs.  For computers with limited input buffering, the Daytronic Model PC-HSICA High-Speed Interface Card is available.

For easy configuration and monitoring of a multinode network, Daytronic's StartPAC 100 software is available free of charge.
