1.3 What is the ACCU-GAGE?

Sensotec ACCU-GAGE Digital Pressure Indicators combine a pressure transducerand a digital signal-conditioner into a single enclosure. These high-accuracy instru-ment are designed for use in both laboratory and industrial applications. A wide vari-ety of pressure ranges are available. The operation of an ACCU-GAGE instrument isbased on digital technology to provide improved accuracy, superior ease of setup, anda wealth of features.

1.3.1 Features The main features of ACCU-GAGE instruments are:

• Four alarm limits with open-collector outputs and versatile setup• Wide variety of pressure ranges from 15 to 60,000 PSI.• Up to 50,000 part resolution• Field selectable display and calibration engineering units• RS-232 communications standard (RS-485 optional)• Local or remote setup using the RS-232 or RS-485 port• Push-button on/off tare feature• Peak/Valley value capture

1.3.2 Models Several models are available with various accuracies and available pressure ranges.See “Chassis Specifications” on page 22 for details of each model.

1.3.3 OptionalVirtual Channels

The pressure transducer is connected to a hardware Input channel of the digital signalconditioner. This channel is referred to as “CHANNEL 01”. Virtual channels are soft-ware based devices that occupy a channel number, but not a physical slot, in theinstrument.

Several different types of optional Virtual channels are available in order to customizean ACCU-GAGE instrument for a particular application.

• Split Display Virtual channels allow the displaying of any two channel’s track, peakor valley values at the same time.

• Mathematics Virtual channels run small programs written in an interpretive lan-guage called SensoCode. This provides great flexibility which allows the ACCU-GAGE to do many jobs which otherwise requires a personal computer or PLC.

Chapter 2Getting Started Quickly

2.1 Pressure Connection

Before connecting to the instrument’s pressure port, verify that the correctthreads are being used.

On 1/4” NPT pressure fittings, the use of a pipe thread sealant (such as Teflon®tape) is recommended to ensure a leak-tight seal.

Always use a backing wrench when connecting to the instrument’s pres-sure port.

2.2 Turn on the Instrument

ACCU-GAGE instrument are calibrated at the factory and need no further calibra-tion prior to initial use.

Connect the power cord between the instrument power source and the instru-ment, and turn the On/Off switch on the back of the instrument to the On position.

The instrument enters its INITIALIZE mode that lasts a few seconds per channel.

When the instrument enters its normal operating mode (RUN mode), you will seethe following format on the front panel display:

1111•••• 00000. P00000. P00000. P00000. PSISISISIGGGG """"

where:

• Channel number: “1” is the channel number.• Value type: The next character indicates the nature of the following value.

A blank character indicates the tracking value. The instrument is “tracking” thesignal, continuously updating the display in response to the input pressure.

Chapter 3Operating Modes

3.1 Operating M odes

ACCU-GAGE instruments have four modes of operation:

• INITIALIZE, to test the digital signal conditioner and transducer upon powerup

• RUN, normal operation• ERROR, which indicates that an abnormal situation has occurred that

stopped the operation of the instrument• SETUP, a menu which allows setup and calibration of the chassis and its

channels.Each of these will be described in this chapter.

3.2 INITIALIZE Mode

When the instrument is powered up or otherwise reset, it enters the INITIALIZEmode. As the instrument enters this mode, all segments of the display and allfront panel indicator lights (if available) illuminate momentarily. Next, each chan-nel in the instrument is checked for proper operation.

If a problem is detected, the instrument may enter the ERROR mode.


3.3 RUN Mode

After the INITIALIZE mode finishes, the instrument enters the RUN mode, its normalmode of operation.

3.3.1 Display

Upper line The display will show a channel number on the far left, followed by the channel’s oper-ation messages.

For example, Channel 01, the Pressure Input Channel, will use the format below:

1111•••• 00000000000000000000.... PSIPSIPSIPSIGGGG """"

where:

• Channel number: “1” is the channel number.• Value type: The next character indicates the nature of the following value.

A blank character indicates the display is being continuously updated by “tracking”the input signal to the channel.A “••••" character indicates the peak value (highest value seen since the [CLEAR]button was last pressed).A “––––" character indicates the valley value (lowest value seen since the [CLEAR]button was last pressed).

• Data value: “00000.” displays the value from the transducer in engineering units.• Units label: “PSIG” indicates the engineering units being used (up to 4 charac-

ters).• Tare indicator: A “""""“ symbol indicates tare is off; a “ËËËË“ symbol indicates tare is on.

Lower Line The content of the display’s lower line is selected with the “DDDDIIIISSSSPPPPLLLLAAAAY MY MY MY MEEEENNNNUUUU -> LLLLOOOOWWWWEEEERRRR MMMMODODODODEEEE”menu item as either displaying an additional Virtual channel or indicating the status ofLimits. See “Indicator Lights” on page17.

3.3.2 [VALUE]button

After the channel number, the next characters indicate which data value for the dis-played channel is shown. There are three (possibly four) data values available fromeach channel:

• (blank), tracking data value• “••••", peak data value, (highest value since the peak/valley detector was cleared)• “––––", valley data value, (lowest value since the peak/valley detector was cleared)• “Û", percentage of the Analog-to-Digital converter’s full-scale digitizing capability.

This data value is only available when the channel’s “DDDDIIIIAAAAGGGGNNNNOOOOSSSSTTTTIIIICCCCSSSS->DDDDIIIISSSSPPPPLLLLAAAAYYYY ADADADADCCCC”menu item is set to “ON”.

Pressing and releasing the [VALUE] button cycles though the available sources fordata values for the displayed channel.

3.3.3 [CLEAR]Button

Pressing and releasing the [CLEAR] button will reset the peak and valley values of thechannel being monitored by the display to the track value. Additionally, any limits inthe instrument that are “latched” will be reset.

To clear the peak and valley values of all channels (including optionally installed Vir-tual channels) simultaneously, use the System connector’s Function Input #2 pin. See“System Connector” on page29 for details.

To clear the peak and valley values of Channel 01, the Pressure Input Channel,regardless of which channel is being monitored by the display, use the channel’sAUX1 or AUX2 control pins on its connector. See “Wiring” on p age62.

3.3.4 [CHANNEL]button

If the configuration of the instrument contains more than one channel, the leftmost characters of the display indicates which channel the display is monitoring.Pressing and releasing the [CHANNEL] button will cause the next channel to bedisplayed.

The [CHANNEL] button cannot be used to change which channel the lower line ismonitoring. That is selected with the “DDDDIIIISSSSPPPPLLLLAAAAYYYY MENMENMENMENUUUU -> LLLLOOOOWWWWEEEERRRR CHANNECHANNECHANNECHANNELLLL” menu item.

3.3.5 [TARE] button To reset the channel’s display to zero, press the [TARE] button while in RUNmode. To restore the tare value, press the [TARE] button again. The “Tare” indica-tor will illuminate when tare is on.

To tare all channels (including optionally installed Virtual channels) simulta-neously, use the System connector’s Function Input #1 pin. See “System Connec-tor” on page29.

To tare the Pressure Input Channel regardless of which channel is being moni-tored by the display, use the channel’s AUX1 or AUX2 control pins on its connec-tor. See “Wiring” on pag e62.

3.3.6 Indicator Lights A “""""“ symbol on the right side of a channel’s display indicates tare is off for thatchannel; a “ËËËË“ symbol indicates tare is on.

If the lower line of the display is configured with the “DDDDIIIISSSSPPPPLLLLAAAAY MY MY MY MEEEENNNNUUUU -> LLLLOWOWOWOWEEEERRRR MMMMODODODODEEEE”menu item as “LLLLIIIIMMMMIIIIT 01T 01T 01T 01----00004444”, then the lower line will monitor the status of Limits 1, 2,3 and 4. A “""""“ symbol indicates a limit is deactivated; a “ËËËË“ symbol indicates a limitis activated. For example:

LLLL1111"""" LLLL2222"""" LLLL3333ËËËË LLLL4444ËËËË

indicates that Limit 1 and Limit 2 are deactivated and Limit 3 and Limit 4 are acti-vated. See “LOWER MODE Menu Item” on page53.

These indicators may be overridden by the operation of a Mathematics Virtualchannel in special applications.


3.4 ERROR mode

The instrument enters the ERROR mode when a critical error occurs that prevents theinstrument from operating. The display alternates between displaying a two-digit codein the form “ERROR xx ON CH.yy” and a short description of the error. The first twodigits “xx” hold the error code. The last two digits, “yy” is channel number that causedthe error. For example, “EEEERRRRRRRROOOORRRR 66660000 OOOONNNN CCCCHHHH....00001111” indicates that error number 60 occurred onchannel 1.

While the instrument is in the ERROR mode, no other operations are taking place.See “Error Message List” on page 86 for a list of error codes and their probablecauses.

Chapter 4Chassis Models

4.1 Introduction

Sensotec ACCU-GAGE instruments are available in several different models. Allinclude one built-in Pressure Input channel and can be ordered with optional Vir-tual channels for application specific applications.

The Pressure Input channel is a printed circuit board that occupies a physical slotinside the instrument’s chassis. A 12-pin connector are located on the rear panelto connect to the Pressure Input. This channel is identified as channel 01.

A Virtual channel exists in software only; it does not occupy a physical slot insideof the instrument’s chassis. There is no rear-panel connector for a Virtual chan-nel. However, a Virtual channel does require a channel number.

5.3 Function Input Pins

5.3.1 Overview To use a Function Input pin (9, 10, 11 or 21), connect it to the DGND (pin 19) momen-tarily. This can be accomplished by a push button switch, relay contact closure, orPLC output.

Usually, the Function Input pins perform the default actions described in the “SystemConnector Pinout” on page30. However, a SensoCode program running on a Mathe-matics Virtual Channel may replace these default actions. Consult the CustomerInformation Sheet included with your instrument for details.

5.3.2 Example For example, assume that you wish to use Function Input #3 to tare all channels in theinstrument simultaneously. Connect a push-button switch as shown below.

Figure 5-1: Function Input Example


5.4 Limit Output Pins

5.4.1 Overview An open-collector output is a transistor logic output that can be used to control DCloads, drive opto-isolators or relays, or interface directly to logic circuitry. They actvery much like switches: low resistance when turned on and high resistance whenturned off. You can use them as you would a dry relay contact, with the followingrestrictions:

• The voltage applied must be DC• The polarity of the DC voltage must be observed• Maximum voltage: 50VDC• Maximum power: 2.0W

When Limits 1, 2, 3, or 4 are activated, the corresponding open-collector Limit Outputpin on the System connector will be connected to the DGND (Digital Ground) pin.However, a SensoCode program running on a Mathematics Virtual Channel mayoverride this behavior. Consult the Customer Information Sheet included with yourinstrument for details.

5.4.2 Example For example, assume that a remote indicator is to be lighted when Limit 1 is activated.An external 24 VDC power supply connects to the indicator.

When Limit 1 is deactivated, there is high resistance between the Limit 1 Output pinand the DGND (Digital Ground) pin; little current flows in the circuit and the light is off.When Limit 1 is activated, there is low resistance between the Limit 1 Output pin andthe DGND (Digital Ground) pin; the light turns on.

The resistor limits the current flowing in the circuit when the light is lighted to 48 mA.According to Ohm’s Law:

Lights or other indicators have voltage, current, and/or power ratings that must beobserved in order to avoid damaging them.

Chapter 7Serial Communications

7.1 Overview

ACCU-GAGE Series instruments are designed to communicate with a remotecomputer system or terminal for the purpose of transferring data values from theinstrument to the remote system. The remote computer or terminal also can con-trol many of the functions performed by the instrument.

Since the Model AG400 and AG401 instruments are very similar to Sensotec’s SCSeries instruments, refer to document p/n 008-0610-00, “SC Series Communica-tions Guide” for details regarding serial communications. This document can bedownloaded from Sensotec’s web site, www.sensotec.com. The “SC SeriesCommunications Guide” assists with the hookup and wiring for data communica-tions and provides detailed information of all the available commands.

7.2 Rear Panel Connector

The System connector on the instrument’s rear panel is used, among other things,for serial communications. See “System Connector” on page 29 for wiring infor-mation.

All of the serial communications pins on the 25-pin System connector have 500Vof electrical isolation from all other pins and connectors on the instrument. Addi-tionally, all serial communications pins are protected against electrostatic dis-charge (ESD).


7.3 Communications Protocol

7.3.1 RS-232 vs.RS-485

ACCU-GAGE instruments are available with either of two communications protocols,RS-232 or RS-485. Only one of these can be installed at a time at the factory.

• RS-232 provides for only one receiver and transmitter per loop, and a loop lengthof no more than 50 feet.

• RS-485 allows up to 32 devices per loop, and a loop length of no more than 4000feet. All devices receive messages in parallel on the line, the so-called “multi-drop” system. To avoid garbled transmissions, only one device should respond toa particular message. Therefore, every device on the loop must have a uniqueaddress.

If you have an instrument with more than one channel, transmission must beaddressed to the appropriate channel within the instrument.

7.3.2 Parameters All ACCU-GAGE instruments use no parity, 8 data bits, and 1 stop bits (“N,8,1”) forserial communications. Baud rates available are 300, 600, 1200, 2400, 4800, 9600,19200 and 38400. As shipped from the factory, all instruments are set at 9600 baud.The baud rates are selected via the RS-232 or RS-485 and not though the front panel.

7.4 Serial Com. Menu

7.4.1 Overview The Serial Com menu allows you to examine the settings for serial communications aswell as test the communications link. You cannot change the settings for serial com-munications through the menus; these settings can only be changed via serial com-munications.

Detailed instructions on operating the instrument in the SETUP Menu mode can befound in “SETUP Menu mode” on page 19. A diagram of all menus is located in“Setup Menu Reference” on page 91.

7.4.2 INTINTINTINTEEEERFACERFACERFACERFACE

Menu ItemThis menu item indicates which serial communications interface is installed in theinstrument: “RRRRSSSS----222233332222” or “RRRRSSSS----444488885555”.

7.4.3 ADDRESADDRESADDRESADDRESSSSS MenuItem

This allows you to examine the two-character address that the instrument will respondto. The default address of “00” (ASCII codes decimal 30, decimal 30). Please see the“SC Series Serial Communications Guide” for information on using the “W4” com-mand to change the address.

7.4.4 BAUD RATEBAUD RATEBAUD RATEBAUD RATE MenuItem

This allows you to examine the baud rate that the instrument uses for serial communi-cations. The default baud rate is 9600. Please see the “SC Series Serial Communica-tions Guide” for information on using the “W1” command to change the baud rate.

7.4.5 AUAUAUAUTTTTO LINEO LINEO LINEO LINE----FEEDFEEDFEEDFEED

Menu ItemThis allows you to examine the setting (on/off) of the auto line-feed function. Whenset to “on”, a line-feed character (ASCII code decimal 10) is transmitted just before thecarriage return (ASCII code decimal 13) that signifies the end of the instrument’sresponse.

If the instrument is connected to a dumb terminal or printer, inserting a line feedbefore the carriage return will make each message sent by the instrument appear on aseparate line and thus be easier to read.

The default setting is “on”.

7.4.6 TTTTRRRRANSMITANSMITANSMITANSMIT TESTTESTTESTTEST

Menu ItemWhen this menu item is selected, the instrument immediately transmits the message“AAAADDDDDDDDRRRREEEESSSSSSSS nnnnn Tn Tn Tn TEEEESSSSTTTT” where “nn” is the two-character address of the instrument. Then themessage “MMMMEEEESSSSSSSSAAAAGGGGEEEE SSSSEEEENNNNTTTT” is shown on the display.

LIMIT

Chapter 9Limits

9.1 Understanding Limits, Set Points and Return Points

Limits are signal levels at which some action (such as a light to come on or go out,or a switch to close) is desired to take place. The point at which this action takesplace is the SET POINT. The RETURN POINT is the point at which the action thattook place at the SET POINT returns to its original state.

If the SET POINT and RETURN POINT are identical and the signal level ischanging slowly near these points, “chatter” may result and the limit rapidly ener-gizes and de-energizes. To keep this from happening, we can specify the SETPOINT at which the action would occur as well as the RETURN POINT where wewant the action to cease. If the amount of “dead band” between these two valuesis more than the expected noise, the desired action will take place only once. TheSET POINT and the RETURN POINT should always be separated to insure thatsmall amounts of noise on the signal will not become a problem.

A good general rule for SET POINT and RETURN POINT values is that theyshould be separated by at least one percent of the full-scale value.


9.2 Limit Operation

9.2.1 Actions WhenActivated

When Limits 1, 2, 3, or 4 are activated, the following actions occur:

• The front panel light for the limit will illuminate.• The corresponding open-collector Limit Output pin on the System connector will

be connected to the DGND (Digital Ground) pin.

9.2.2 Scan Time The “scan time” or update rate of the limits depends on how many channels areinstalled in the instrument. To determine the scan time of the limits for your particularinstrument, see “SCAN TIME Menu Item” on page35.

9.3 Limit Menus

9.3.1 Overview There are four Limit menus which control the operation of the open-collector LimitOutputs on the System connector.

Detailed instructions on operating the instrument in the SETUP Menu mode canbe found in “SETUP Menu mode” on page 19. A diagram of all menus is locatedin “Setup Menu Reference” on page 91.

9.3.2 LIMIT.LIMIT.LIMIT.LIMIT.EEEENABLENABLENABLENABLE MenuItem

This enables or disables the operation of this limit. The two options for this menuitem are “OOOONNNN” and “OOOOFFFFFFFF”.

9.3.3 LILILILIMMMMIT.SETIT.SETIT.SETIT.SETPPPPOINTOINTOINTOINT

Menu ItemThis is the numeric value, in engineering units, for the signal level that activatesthe limit.

9.3.4 LIMILIMILIMILIMITTTT.RETUR.RETUR.RETUR.RETURNNNN PNTPNTPNTPNT

Menu ItemThis is the numeric value at which the limit deactivates. In general, this numbershould differ from the set point value by at least 1% of full scale.

Carefully consider what value should be entered for the RETURN POINT. If thesignal is expected to approach the SET POINT from a lower value, the RETURNPOINT value should be less (algebraically) than the SET POINT. If the signal isexpected to approach the SET POINT from a higher level, the RETURN POINTshould be higher (algebraically) than the SET POINT.

9.3.5 LILILILIMMMMIT.ENEIT.ENEIT.ENEIT.ENERRRRGIZEGIZEGIZEGIZE

Menu ItemThis specifies when to activate the limit relative to the set point and return point.

The options for this menu item are:

• “SSSSIIIIGGGGNNNNAAAALLLL > S> S> S> SEEEETTTTPPPPOOOOININININTTTT” means the limit will activate when the signal is higher thanthe set point.

• “SSSSIIIIGGGGNNNNAAAALLLL < S< S< S< SEEEETTTTPPPPOOOOININININTTTT” means the limit will activate when the signal is lower thanthe set point.

• “SSSSIIIIGGGGNNNNAAAALLLL INSIDINSIDINSIDINSIDEEEE” means the limit will activate when the signal is in between theset point and the return point.

• “SSSSIIIIGGGGNNNNAAAALLLL OUTSIDOUTSIDOUTSIDOUTSIDEEEE” means the limit will activate when the signal is not in betweenthe set point and the return point.

The figures below further illustrate the differences between these settings.

Chapter 10Pressure Input Channel

10.1 Features

The Pressure Input channel provides a DC excitation voltage to and accepts milli-volt signals from the internal pressure transducer. These millivolt signals are digi-tized, converted into engineering units, and placed into the track, peak and valleydata values of the channel. Setup and calibration of the channel to the pressuretransducer is made at the factory. Re-calibration can be made manually throughthe SETUP mode with the known-load calibration method.

The analog-to-digital converter input circuit is ratiometric to the excitation voltage,features digital, low-pass filtering, and typically ±50,000 count resolution.

The engineering units used to display the pressure readings are field selectablefrom a built-in conversion table. In addition, the engineering units used for calibra-tion can be independently selected.

Two rear panel control inputs can be field-configured for such functions as remotetare, track/hold, disabling peak/valley detection and clearing the peak/valley val-ues. A voltage or current digital-to-analog output is also provided.


10.2 Wiring

Connect the Pressure Input channel by wiring it to its 12-pin connector. The pin-out forthis connector is shown on the following table.

The Analog Output and Analog Return pins are electrically isolated from all other pinson the instrument.

Do not connect anything to the pins labeled as “N/C”. Damage to the instru-ment or loss of accuracy may result.

10.3 Calibration

10.3.1 CalibrationConsiderations

If you are not familiar with operating the instrument in the SETUP menu mode,see “SETUP Menu mode” on page 19. A listing of all menu items is given in“Setup Menu Reference” on page 91.

In order to obtain optimum performance from the instrument when testing or re-calibrating, Sensotec recommends the following:

• Allow a 5-minute warm-up period before testing or calibration.• Just prior to starting the calibration, exercise the pressure transducer by

applying momentarily and then removing full-scale pressure.• The pressure standard you use should be at least 4 times more accurate than

the specification of the instrument.

10.3.2 RequiredPressures

In order to re-calibrate the instrument, you must have a precision pressure stan-dard that can produce pressures near the zero-scale, quarter-scale, half-scale,three-quarter scale and full-scale pressures for the instrument's range. Examinethe table below to determine the five pressures needed to calibrate your instru-ment. For example, if your instrument has a range of 100 PSIG, your pressurestandard must be able to accurately produce pressures near 0 PSI, 25 PSI, 50PSI, 75 PSI and 100 PSI.

10.3.3 CalibrationUnits of Measure

As shipped from the factory, instruments are usually calibrated in PSI regardlessof the field-selected display engineering units. If you wish to re-calibrate theinstrument using a unit-of-measure other than PSI, you can use the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN

UUUUNNNNIIIITTTTSSSS menu item to change the units-of-measure that the instrument uses for cali-bration. Then, you can re-enter the KKKKNONONONOWWWWN PN PN PN POOOOIIIINNNNTTTT menu items to match the pressuresyou are able to produce.

10.3.4 Traceability To maintain NIST traceability, Sensotec can re-calibrate an ACCU-GAGE instru-ment for you. NIST certificates can be ordered as a separate accessory for anominal fee.

10.3.5 CalibrationProcedure

Step 1: Remove the SETUP protection jumper per “SETUP Protection Jumper” onpage 26.

Step 2: Enter the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN TYPTYPTYPTYPEEEE.There are two methods that can be used to calibrate the transducer to theInput Channel. To obtain maximum accuracy, calibrate using the 5-PointKnown Load Calibration method whenever possible. See “CALIBRATIONTYPE Menu Item” on page67.

Step 3: Enter the CALIBRATION DCALIBRATION DCALIBRATION DCALIBRATION DAAAATATATATA....

You must make certain that the KKKKNNNNOOOOWWWWN PON PON PON POIIIINNNNTTTT menu items match the pressuresyou are able to produce.

Step 4: Perform the calibration.Use the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTEEEE menu item to start the calibration process. You will beprompted to apply loads to the transducer as required.

Step 5: Install the SETUP protection jumper per “SETUP Protection Jumper” onpage 26.

10.5 Channel Menu

The Pressure Input channel is configured and calibrated via its channel menu.Detailed instructions on operating the instrument in the SETUP Menu mode canbe found in “SETUP Menu mode” on page 19. A diagram of all menus is locatedin “Setup Menu Reference” on page 91.

10.5.1 OPEOPEOPEOPERRRRATIONATIONATIONATION

Sub-MenuThis menu controls the operation of this channel when the instrument is in theRUN mode.

AAAAUUUUTTTTOOOO----ZZZZEEEERRRROOOO Menu Item This enables or disables the channel’s automatic zeroing function. The auto-zerofunction can be beneficial by removing the effect of slight temperature shifts in thetransducer’s output. The two options for this menu item are “OOOONNNN” and “OFOFOFOFFFFF”.

When enabled, the channel will reset its tracking value to zero when the trackingvalue has never been more positive than +10 or more negative than -10 displaycounts for any 10 second period.

For example, assume that the display is using two decimal points. If the trackingvalue never leaves the range of ----000000000000....11110000 to ++++000000000000....11110000 for any 10 second period, thentracking value will reset to 000000000000....00000000 automatically.

To compensate for the transducer’s initial warm-up shift, the auto-zerofunction operates every 2 seconds during the first 60 seconds of RUN

mode operation.

PPPPOOOOWWWWEEEERRRR----OOOONNNN SOURCSOURCSOURCSOURCEEEE Menu Item This menu selects which value is displayed by the channel when first entering theRUN mode.

The choices are:

• “TTTTRRRRAAAACCCCKKKK” means the live tracking value of the channel.• “PPPPEEEEAAAAKKKK” means the highest value of the channel.• “VVVVAAAALLLLLLLLEEEEYYYY” means the lowest value of the channel.


10.5.2 DDDDIIIISPLAYSPLAYSPLAYSPLAY UUUUNITSNITSNITSNITS

Menu ItemThis menu item controls how data values are scaled into engineering units, displayedby the channel, and transmitted via serial communications. The Pressure Input chan-nel has conversion factors, given below, for many standard pressure units-of-measurebuilt in. Note that if the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOON UN UN UN UNNNNIIIITTTT is set to something other than PSI, then thechoices available in the DIDIDIDISSSSPPPPLLLLAAAAYYYY UUUUNNNNIIIITTTTSSSS and the associated conversion factors willchange accordingly. For example, if the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOON UN UN UN UNNNNIIIITTTT is set to “kPa” then choicesavailable for the DDDDIIIISSSSPPPPLLLLAAAAYYYY UNITUNITUNITUNITSSSS will be “ kkkkPPPPaaaa to PSto PSto PSto PSIIII”,” kkkkPPPPaaaa to bato bato bato barrrr” , etc.

The decimal point position is set automatically based upon the display scaling in orderto provide the maximum resolution available; it cannot be changed manually.

When the DDDDIIIISSSSPPPPLLLLAAAAYYYY UUUUNNNNIIIITTTTSSSS setting is changed, all LLLLIIIIMMMMIIIITTTT.... SSSSEEEETTTTPPPPOOOOIIIINNNNTTTTs, LLLLIIIIMMMMIIIITTTT.... RRRREEEETTTTUUUURRRRNNNN PPPPNNNNTTTTs, tarevalues, DDDDAAAACCCC.... ZZZZEEEERRRROOOO----SSSSCCCCAAAALLLLEEEE and DDDDAAAACCCC.... FULL-SCALFULL-SCALFULL-SCALFULL-SCALEEEE values in the entire instrument that refer tothis channel will also be converted to the new DDDDIIIISSSSPPPPLLLLAAAAYYYY UNITUNITUNITUNITSSSS setting.

10.5.3 AAAAUUUUXn FUNXn FUNXn FUNXn FUNCCCCTIONTIONTIONTION

Menu ItemsThe AAAAUUUUXXXX1 F1 F1 F1 FUUUUNNNNCCCCTTTTIIIIOOOONNNN and AAAAUUUUXXXX2 F2 F2 F2 FUUUUNNNNCCCCTTTTIIIIOOOONNNN menu items determine what happens when theAuxiliary Function pins (labeled as “AUX1” and “AUX2”) on the channel’s connectorare activated. These pins are “activated” when they are connected to the DigitalGround (labeled as “DGND”) pin. The choices are:

• “DDDDIIIISSSSAAAABBBBLLLLEEEEDDDD” means that activating the pin does nothing.• “TTTTRRRRAAAACCCCKKKK HOLHOLHOLHOLDDDD” means that the tracking, peak and valley values will not be updated.• “HHHHIIIIGGGGHHHH////LLLLOOOOWWWW HOLHOLHOLHOLDDDD” means that the peak and valley values will not be updated.• “HHHHIIIIGGGGHHHH////LLLLOOOOWWWW CLEACLEACLEACLEARRRR” means that the peak and valley values are reset.• “TTTTAAAARRRREEEE OOOONNNN” activates the channel’s Tare function (resets it to zero).• “TTTTAAAARRRREEEE OFOFOFOFFFFF” deactivates the channel’s Tare function.As the Auxiliary Function pins are not isolated, it is recommended that a push-buttonswitch or relay is used to connect these pins to the Digital Ground pin.

10.5.4 CALCALCALCALIIIIBRATIONBRATIONBRATIONBRATION TYPETYPETYPETYPE

Menu ItemThis chooses the type of calibration technique to be used. The choices are:

• “TTTTYYYYPPPPEEEE= 3 P= 3 P= 3 P= 3 POOOOIIIINNNNT CT CT CT CAAAALLLL” means 3-Point Known Load Calibration. You are promptedto apply the loads to the transducer that were entered in the “KKKKNNNNOOOOWWWWNNNN POINT 1/POINT 1/POINT 1/POINT 1/3333 ”and “KKKKNNNNOOOOWWWWNNNN POINT 2/POINT 2/POINT 2/POINT 2/3333 ” and “KKKKNNNNOOOOWWWWNNNN POINT 3POINT 3POINT 3POINT 3////3333” registers. This technique can beused to compensate for the non-linearity in the transducer. The usual loadsused are zero scale, half scale and full scale, but you are not restricted tothese loads.

• “TTTTYYYYPPPPEEEE= 5 P= 5 P= 5 P= 5 POOOOIIIINNNNT CT CT CT CAAAALLLL” means 5-Point Known Load Calibration. You are promptedto apply the loads to the transducer that were entered in the “KKKKNNNNOOOOWWWWNNNN POINT 1/POINT 1/POINT 1/POINT 1/5555 ”,“KKKKNNNNOOOOWWWWNNNN POINT 2/POINT 2/POINT 2/POINT 2/5555 ”, “KKKKNNNNOOOOWWWWNNNN POINT 3/POINT 3/POINT 3/POINT 3/5555 ”, “KKKKNNNNOOOOWWWWNNNN POINT 4POINT 4POINT 4POINT 4////5555” and “KKKKNNNNOOOOWWWWNNNN POINT 5/POINT 5/POINT 5/POINT 5/5555 ” regis-ters. This technique can be used to compensate for the non-linearity in thetransducer. The usual loads used are zero scale, one-quarter scale, halfscale, three-quarters scale and full scale, but you are not restricted to theseloads.

The selection of the calibration type affects what menu items appear in the CCCCAAAALLLLIIII----

BBBBRRRRAAAATTTTIIIIOOOONNNN DATDATDATDATAAAA sub-menu.

To obtain maximum accuracy, always calibrate using the 5-Point KnownLoad Calibration method whenever possible.


10.5.5 CALIBCALIBCALIBCALIBRRRRATIONATIONATIONATION

DADADADATTTTAAAA Sub-MenuThis enters the values that will be used by the instrument when it calibrates itself tothe transducer. The menu items that are displayed will change according to what theCCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN TYPTYPTYPTYPEEEE is set for.

FFFFUUUULLLLLLLL SCALE MV/SCALE MV/SCALE MV/SCALE MV/VVVV MenuItem

The transducer output when its full-scale load is applied to it, in milliVolts-per-Volt.This menu item is used by the instrument to set the gain of its amplifier circuit.

This menu item is specific to the pressure transducer used in a particular instrumentand cannot be changed by the customer.

KKKKNNNNOOOOWWWWNNNN POINT x/POINT x/POINT x/POINT x/yyyy MenuItems

This enters the engineering units for the known-load calibration points. These pointsmust match the actual loads that you will apply to the instrument during calibration.The number of calibrations points depends on the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN TYPTYPTYPTYPEEEE.

When using the 3-Point Known Load Calibration type, the following menu items areavailable:

• “KKKKNNNNOOOOWWWWNNNN POINT 1/POINT 1/POINT 1/POINT 1/3333 ”: point 1 of 3, usually 0% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 2/POINT 2/POINT 2/POINT 2/3333 ”: point 2 of 3, usually 50% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 3/POINT 3/POINT 3/POINT 3/3333 ”: point 3 of 3, usually 100% of the transducer’s full-scale capacity.

When using the 5-Point Known Load Calibration type, the following menu items areavailable:

• “KKKKNNNNOOOOWWWWNNNN POINT 1/POINT 1/POINT 1/POINT 1/5555 ”: point 1 of 5, usually 0% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 2/POINT 2/POINT 2/POINT 2/5555 ”: point 2 of 5, usually 25% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 3/POINT 3/POINT 3/POINT 3/5555 ”: point 3 of 5, usually 50% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 4/POINT 4/POINT 4/POINT 4/5555 ”: point 4 of 5, usually 75% of the transducer’s full-scale capacity.• “KKKKNNNNOOOOWWWWNNNN POINT 5/POINT 5/POINT 5/POINT 5/5555 ”: point 5 of 5, usually 100% of the transducer’s full-scale capacity.

To insure both correct operation of the transducer and application of the load,the instrument expects the voltage applied at each known-load point to beincreasing. For example, the load applied at Known-Load Point 2/5 must

cause the transducer to produce a more positive voltage than at Known-LoadPoint 1/5.

10.5.6 CALCALCALCALIIIIBRATEBRATEBRATEBRATE

Menu ItemThis menu item performs a calibration according to what was entered in the CCCCAAAALLLLIIIIBBBBRRRRAAAA----

TTTTIIIIOOOONNNN TYPTYPTYPTYPEEEE and CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN DATDATDATDATAAAA menu items.

Before performing a calibration, the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOONNNN TYPTYPTYPTYPEEEE must be selected (see“CALIBRATION TYPE Menu Item” on page67), and the CCCCAAAALLLLIIIIBBBBRRRRAAAATTTTIIIIOOOON DN DN DN DAAAATTTTAAAA must

be entered (see “CALIBRATION DATA Sub-Menu” on page68).

For maximum accuracy, allow at least five minutes of warm-up before calibra-tion.

10.5.7 DACDACDACDAC SSSSETUPETUPETUPETUP

Sub-MenuThis sub-menu contains four items that control the Digital-to-Analog Converter (DAC)output of the channel.

DDDDAAAACCCC.... CHANNECHANNECHANNECHANNELLLL Menu Item This chooses which channel will drive the DAC output. Normally, the DAC located ona particular channel will be driven by that channel, but that need not be the case. Forexample, if a Mathematics Virtual channel is installed on the instrument, the output ofthis Virtual channel could be used to drive this channel’s DAC output.

If the DAC is set-up to be driven by its own channel’s tracking value, the Analog Out-put will have the frequency response specified by “Pressure Input Channel Specifica-tions” on pag e64. Otherwise, the Analog Output will operate more slowly.

DDDDAAAACCCC.... SOURCSOURCSOURCSOURCEEEE Menu Item This designates the data source of the channel monitored by the analog output. Eachchannel has three data sources: the live tracking value (TRACK), its highest value(PEAK), and its lowest value (VALLEY).


• “TTTTRRRRAAAACCCCKKKK” means the live tracking value of the channel.• “PPPPEEEEAAAAKKKK” means the highest value of the channel since the peak/valley detector was

last cleared.• “VVVVAAAALLLLLLLLEEEEYYYY” means the lowest value of the channel since the peak/valley detector was

last cleared.If the DAC is set-up to be driven by its own channel’s tracking value, the Analog Out-put will have the frequency response specified by “Pressure Input Channel Specifica-tions” on pag e64. Otherwise, the Analog Output will operate more slowly.

DDDDAAAACCCC.... ZERO-SCALZERO-SCALZERO-SCALZERO-SCALEEEE MenuItem

This specifies what value, in engineering units, corresponds to zero output on theAnalog Output.

“Zero output” might be 0 Volts, 2.5 Volts, 5 Volts, 4 mA or 12 mA depending on if thechannel has a voltage or current output and how it is configured. See the “Digital-to-Analog Output” section of this chapter for details.

DDDDAAAACCCC.... FULL-SCALFULL-SCALFULL-SCALFULL-SCALEEEE MenuItem

Specifies what value, in engineering units, corresponds to full output on the AnalogOutput.

“Full output” might be 5 Volts, 10 Volts or 20 mA depending on if the channel has avoltage or current output and how it is configured. See the “Digital-to-Analog Output”section of this chapter for details.

• “OOOOFFFFFFFF” will allow normal operation of the channel.


10.6 Analog Output Configuration

10.6.1 Identifyingthe Output Type

A Pressure Input channel is available with one of two types of digital-to-analog (DAC)outputs: voltage or current. You can determine which type of output a channel has byone of three ways:

• Consulting the instrument’s Customer Information Sheet• Examining the SSSSYYYYSSSSTTTTEEEEMMMM MENMENMENMENUUUU -> CCCCOOOONNNNFFFFIIIIGGGGUUUURRRRAAAATTTTIIIIOOOONNNN -> CCCCHHHHAAAANNNNNNNNEEEELLLL nn TTTTYYYYPPPPEEEE menu item where nn is

the number of the channel. If the channel’s type is PPPPRRRREEEESSSSSSSSUUUURRRREEEE VouVouVouVoutttt, it has a voltageoutput. If the channel’s type is PPPPRRRREEEESSSSSSSSUUUURRRREEEE IIIIoooouuuutttt, it has a current output.

• Examining the channel’s circuit board as shown in the figure below.

10.6.2 ChannelMenu Items

The Analog Output can be driven by any channel’s track, peak or valley value.

See the “Channel Menu” section earlier in this chapter for a complete listing of SETUPmenu items available on the DDDDAAAACCCC.... SETUSETUSETUSETUPPPP sub-menu.

10.6.3 OutputSelection

Jumpers located on the channel’s circuit board determine what outputs are generatedwhen the value selected to drive the Analog Output (from the DDDDAAAACCCC.... CCCCHHHHAAAANNNNNNNNEEEELLLL and DDDDAAAACCCC....

10.7.1 Error Messages See “Error Messages” on page85 for information relating to error messages.

10.7.2 CommonProblems and

Solutions

Erratic Display Make sure that the pressure on the transducer is constant.

Instruments that read barometric pressure will indicate very small changes in airpressure, such as those caused by even a modest change in altitude.

SSSSEEEETTTTUUUUPPPP PROTECTEPROTECTEPROTECTEPROTECTEDDDD on Display As shipped from the factory, the SETUP Menu mode is disabled so as to protectthe setup and calibration data of the instrument. If a re-calibration or change inthe instrument’s settings is required, see “SETUP Protection Jumper” on page26.

+OVLD or -OVLD onDisplay

Check “Wiring” on page62 and make certain that nothing is connected to the pinslabeled as “N/C”.

Analog Output Incorrect Make certain of the type of Analog Output (voltage or current) that the channel isequipped with; see “Identifying the Output Type” on page72.

Use the DDDDIIIIAAAAGGGGNNNNOOOOSSSSTTTTIIIICCCCSSSS -> DDDDAAAACCCC FFFFUUUULLLLLLLL SSSSCCCCAAAALLLLEEEE and DDDDIIIIAAAAGGGGNNNNOOOOSSSSTTTTIIIICCCCSSSS -> DDDDAAAACCCC ZZZZEEEERRRRO SO SO SO SCCCCAAAALLLLEEEE menu items toforce the Analog Output to a known output. Then, adjust your readout device,panel meter, PLC or data acquisition system to match.

Check the output selection jumpers; see “Output Selection” on page72.

Auxiliary Function PinsNot Operating

Make sure that the AAAAUUUUXXXX1111 FFFFUUUUNNNNCCCCTTTTIIIIOOOONNNN or AAAAUUUUXXXX2 F2 F2 F2 FUUUUNNNNCCCCTTTTIIIIOOOONNNN SETUP menu items are set cor-rectly; if they are set to DDDDIIIISSSSAAAABBBBLLLLEEEEDDDD then they will not operate.

The Auxiliary Function (“AUX1” and “AUX2”) pins must be connected to pin 10,not pin 8, to activate them.

Pressure Port Rotates Always use a backing wrench when connecting to the pressure port. If the pres-sure transducer has become loose in its mounting, you can re-secure it. See“Pressure Transducer Mounting” on page 25.

Chapter 11Split Display Virtual Channel

11.1 Features

The Split Display Virtual Channel allows the display of two track, peak or valleyvalues from any two channels at the same time. One value is displayed on the leftside of the display, and another value is displayed on the right side.

The display setup used to format each value is inherited from the source channelof the value.

Split Displays are most useful when an instrument has many Virtual Mathematicschannels installed.

11.2 Wiring

A Virtual Channel exists in software only; it does not occupy a physical slot insideof the instrument’s chassis. However, a Virtual Channel does require a channelnumber.

There is no rear-panel connector for a Virtual Channel.

11.3 Setup Procedure

If you are not familiar with operating the instrument in the SETUP menu mode,see “SETUP Menu mode” on page19. A listing of all menu item is given in “SetupMenu Reference” on page91.

Step 1: Enter the value to be displayed on the left side with LLLLEEEEFFFFT CT CT CT CHHHHAAAANNNNNNNNEEEELLLL and LLLLEEEEFFFFTTTT

Chapter 12Mathematics Virtual Channel

12.1 Features

The Mathematics Virtual Channel is a powerful, flexible means to allow ACCU-GAGE instruments to perform simple to moderate functions that previouslyrequired the use of expensive programmable logic controllers (PLC).

A Mathematics Virtual Channel is akin to a PLC; it can execute programs writtenin an interpretive language called SensoCode. At the time of order, your specificapplication is analyzed by our sales and engineering staff and one or more Sen-soCode programs are created. These SensoCode programs are loaded into theMathematics Virtual channels of the instrument at the factory. The end result isan instrument that meets your specific needs but is built with proven hardwareand software.

SensoCode programs allow the instrument to perform a variety of functionsincluding:

• Mathematics : addition, subtraction, multiplication, division, square roots, etc.• Logical : if/then condition statements, comparison of values• Timing• Input : from any channel’s track, peak or valley values, open-collector inputs,

constant user-entered values from the SETUP menu• Output : Each Mathematics Channel generates its own track, peak, and valley

values. A SensoCode program can “take control” of the Limit Output and/orfront panel indicator lights.


12.2 Wiring

A Virtual Channel exists in software only; it does not occupy a physical slot inside ofthe instrument’s chassis. However, a Virtual Channel does require a channel number.

A SensoCode program that is executed by a Mathematics Virtual Channel can use theSystem connector’s Limit Output pins and Function Input pins for its own purposes.Consult the Customer Information Sheet included with the particular instrument fordetails.

12.3 Setup Procedure

If you are not familiar with operating the instrument in the SETUP menu mode,see “SETUP Menu mode” on page19. A listing of all menu item is given in “SetupMenu Reference” on page91.

Step 1: Examine the Customer Information Sheet.The instrument’s Customer information Sheet contains important informa-tion about what each Mathematics Channel does and what Function Inputsand/or Limit Output pins of the System connector are used.

Step 2: Wire to the pins on the System connector.See “System Connector” on page 29. It is important to read the CustomerInformation Sheet to determine the wiring for your application.

Step 3: Verify operation.


12.4 Channel Menu

Each Mathematics Virtual Channel can have its configuration and SensoCode pro-gramming examined via its channel menu. It is not possible to alter the SensoCodeprogram with the SETUP menu. Detailed instructions on operating the instrument inthe SETUP Menu mode can be found in “SETUP Menu mode” on page19. A diagramof all menus is located in “Setup Menu Reference” on page91.

12.4.1 SSSSEEEENSOCODNSOCODNSOCODNSOCODEEEE P/NP/NP/NP/N

Menu ItemThis menu item displays the part number and revision level of the SensoCode pro-gram loaded in this Mathematics Virtual Channel.

12.4.2 USERUSERUSERUSER VVVVALUESALUESALUESALUES

Sub-MenuThis sub-menu contains menu items for each of the User Values. User Values areconstant numeric values that can be edited by the user and read by a SensoCode pro-gram. The use of each UserValue depends on the SensoCode program loaded in theMathematics Virtual Channel.

By default, the four items on this menu are UUUUSSSSEEEERRRR VALUVALUVALUVALUE 1E 1E 1E 1, UUUUSSSSEEEER VAR VAR VAR VALLLLUUUUE 2E 2E 2E 2, UUUUSSSSEEEERRRR VVVVAAAALLLLUUUUEEEE 3333 andUUUUSSSSEEEERRRR VVVVAAAALLLLUUUUE 4E 4E 4E 4. However, a SensoCode program can alter the menu item text for each ofthe User Values to make them more relevant to the operator. For example, UUUUSSSSEEEERRRR VVVVAAAALLLLUUUUEEEE

1111 might be re-titled JJJJEEEELLLLLLLLYYYY BEAN CBEAN CBEAN CBEAN COUNOUNOUNOUNTTTT.

12.4.3 VIEW SENSVIEW SENSVIEW SENSVIEW SENSOOOOCODECODECODECODE

Menu ItemThis menu item allows the display of each “step” (either an operand or an instruction)of the SensoCode program presently loaded into a Mathematics Virtual Channel.Pressing [ENTER] will display the next step of the SensoCode program until the entireprogram has been viewed.

SensoCode programs cannot be altered with the SETUP Mode menu; they can onlybe loaded via the serial port with the Instrument Utility Software.

12.4.4 VVVVIIIIEW COEW COEW COEW COMMMMMANDSMANDSMANDSMANDS

Sub-MenuThis sub-menu contains menu items for each of the Command Strings that can beused by a SensoCode program. Command Strings are text constants that can beread by a SensoCode program. They are not able to be changed with the SETUPmenu. The use of each Command String depends on the SensoCode programloaded in the Mathematics Virtual Channel.

The items on this menu are CCCCOMOMOMOMMMMMAAAANNNND 0D 0D 0D 0, CCCCOOOOMMMMMMMMAAAANNNND 1D 1D 1D 1 ,CCCCOOOOMMMMMMMMAAAANNNND 2D 2D 2D 2, CCCCOOOOMMMMMMMMAAAANNNND 3D 3D 3D 3, CCCCOOOOMMMMMMMMAAAANNNND 4D 4D 4D 4, CCCCOOOOMMMMMMMMAAAANNNND 5D 5D 5D 5,CCCCOOOOMMMMMMMMAAAANNNND 6D 6D 6D 6, and CCCCOOOOMMMMMMMMAAAANNNNDDDD 7777.
