The Model 4040 is a single-channel conditioner for measurement of

flow, rpm

, and other phenomena that can be sensed by pulse trans-

former transducers with two-wire isolated windings (tachometer

pickups, turbine flowmeters, etc.), transistor or logic-circuit drivers,

"zero-velocity" (true digital output) sensors, and similar frequency-

generating transducers. A "tare" function is preprogrammed for the

frequency input, and may be activated by a front-panel push button.

Via front-panel buttons, you can also display and reset MAXIMUM,

MINIMUM, and "MAX minus MIN" values for the "tared" analog input.

Unless otherwise specified at the time of order, your Model 4040 has

been set, prior to shipment, to a

standard configuration

. THIS CON-

FIGURATION IS FULLY ADEQUATE FOR MOST APPLICATIONS,

AND LETS YOU CONTROL BASIC INSTRUMENT SETUP AND

OPERATION SOLELY BY MEANS OF THE SIX FRONT-PANEL PUSH

BUTTONS AND THE EIGHT REAR-PANEL LOGIC I/O. A full listing of

your 4040's standard configuration is given in Appendix A.

Like all 4000 Series instruments, however, the 4040 can be rapidly and

easily reprogrammed in the field, to provide a variety of unique

application solutions. For such reprogramming you can use either

• an optional Model 10P80D Extended Keyboard that plugs directly

into the rear of the 4040 unit, or

• the optional StartPAC 100 Software (Model GS-SP100).* This

software applies to ALL Daytronic RS-485 networkable instru-

ments, and offers a number of valuable utilities for terminal

emulation, node configuration, network monitoring, data display

and logging, etc. IT IS SUPPLIED FREE OF CHARGE WITH ALL

4000 SERIES MODELS. For details on the installation and

operation of StartPAC 100, see the

StartPAC 100 Instruction

Manual

StartPAC 100 lets a connected computer serve as a "dumb" terminal

for entry of the specific MNEMONIC COMMANDS required to repro-

gram the 4040. These commands may also be issued directly to the

4040 via the optional Extended Keyboard. Commands which are

common to all 4000 Series models are described in detail in the

1.2

Model 4040 Description and Specifications 1.a

* Alternatively, you can use any of a number of commercially available

terminal emulation programs

to issue commands directly to the 4040.

System Instruction Manual

. IT IS RECOM-

MENDED THAT YOU STUDY THE

SYSTEM INSTRUCTION

MANUAL

BEFORE YOU ATTEMPT ANY RECONFIGURATION OF

YOUR MODEL 4040 BEYOND THAT DISCUSSED IN THE

APPENDICES OF THE PRESENT MANUAL.

See Appendix B of the present manual for direct RS-232-C connections

between the 4040 and a computer or printer.

The 4040's "live" input is initially configured for a full-scale transducer

range of

32000 Hz

and an input sensitivity range of

100 mV to 15 V.

you require a different transducer-range or sensitivity-range setting for

your 4040, see Appendix D. INPUT AND SENSITIVITY RANGES

SHOULD BE SET

BEFORE TRANSDUCERS ARE CONNECTED.

Note too that the active low-pass filter for the 4040's "live" analog input

is initially set for the response characteristics given as "3" under

Specifications, below. To change this response, see Appendix E.

Unless otherwise specified, every 4040 comes with the standard

engineering-unit legends

and

button-function indicators

shown in Fig. 1.

Different legend/indicator films may be optionally obtained. Via optional

keyboard or computer, you can instruct the 4040 to light any one or a

combination of given legends and indicators. See Appendix C for

"Legend and Indicator Annunciation." Note that under the "standard

configuration," the "F2" indicator will

always

be on when the 4040 is in

"RUN-TIME" mode.

When using the 4040 to measure

frequency itself

, you can apply a

simple "ABSOLUTE" CALIBRATION technique via the SCALING

FACTOR (EMM) command. The procedure is given in Appendix F,

which also describes an alternative "COMPUTED" CALIBRATION

method using the FREQUENCY CALIBRATION (FRQ) command.

NOTE: WITH THE EXCEPTION OF APPENDICES C THROUGH F,

THE PRESENT MANUAL WILL ONLY TREAT PROCEDURES AND

CONSIDERATIONS WHICH ARE RELEVANT TO THE 4040 "STAN-

DARD CONFIGURATION" AND WHICH DO NOT REQUIRE A

CONNECTED COMPUTER OR KEYBOARD. FOR INFORMATION

ON THE FULL FUNCTIONALITY OF YOUR MODEL 4040, SEE THE

OPTIONAL
