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.
If
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
SYSTEM INSTRUCTION MANUAL
