Description

The Mercury Instruments Pulse Accumulator is a 2-channel, battery-powered electronicrecorder that is designed to receive and store low-frequency pulses. Two independentpulse sources may be connected to the input channels, each having its own 3.5vdc wet-ting voltage. Since the two channels act as independent accumulators, typical installa-tions might include:

a) One pulse source (pulse transmitter or meter pulse) connected to either Ch1 or Ch2.b) Two separate pulse sources (pulse transmitters or meter pulses) connected to Ch1 for

the first source and Ch2 for the second source.c) Pulse outputs from one volume corrector connected to both channels, Ch1 for

corrected volume pulses and Ch2 for uncorrected volume pulses.

In an operational Pulse Accumulator, pulses received at either input are assigned a fixedamount of volume via their respective Input Pulse Value selections. Additional pulsescaling can be applied using their respective Input Pulse Scaling items (if needed) beforethe pulses are stored (added) to their respective accumulated totals. Ch1 versus Ch2volumes units can be independently scaled. The number of digits (from 4 to 8 digits) canalso be assigned for both channels. Below are the items associated with AccumulatedVolumes:

Ch1 Item# Ch2 Item#Input Pulse Value 098 912

Input Pulse Scaling 114 913(this feature is normally not needed)

Accumulated Volume 002 910

Incremental Accumulated Volume 226 911

Accumulated Volume Units 092 458

Accumulated Volume # of Digits 097 097

Page 6

Additionally, each pulse channel may also be configured to receive a user-specifiedFixedFactor multiplier. By default, this multiplier is disabled but may be activated byinserting the desired factor into item 044 for Ch1 and item 440 for Ch2. TheFixedFactor feature is normally used to adjust the accumulated uncorrected volume for afixed pressure factor or fixed temperature factor (or both). Below are the items associ-ated with FixedFactor Volume:

Ch1 Item# Ch2 Item#FixedFactor Volume 000 908

Incremental FixedFactor Volume 225 909

FixedFactor Value 044 440

FixedFactor Volume Units 090 457

FixedFactor Volume Digits 096 096

The basic Pulse Accumulator assembly includes a Mercury Instruments Messenger Mo-dem to provide telecommunications. The Pulse Accumulator can receive host-initiatedcalls (Call-out) or provide instrument-initiated calls (Call-in). Call-in type calls can bethe result of an instrument Alarm, a Scheduled call or the shorting of the ‘Force-a-call’jumper pins. The ‘Force-a-call’ pins are located at J1 on the Pulse Accumulator circuitboard. (If specified, an optional externally-mounted push-button may be installed andconnected to the pins at J1. That way, a call can be forced without removing the coverfrom the enclosure.) The ‘Force-a-call’ function can only be used if item 333 (Call-InTrigger) is set to Alarm Call-in, Scheduled Call-in or both. If instrument-initiated callsfail to connect to a host system, primary and secondary call-in retries are activated in aneffort to complete the call-in process.

When some other communication device (such as cellphone, radio, etc.) is substitutedfor the Messenger Modem, the Pulse Accumulator’s Power Control feature can periodi-cally apply power to that modem device. This feature is useful when the communicationdevice is battery powered and extended battery life is needed. The majority of the itemsfrom 485 to 497 are used to configure the power-on start time, stop time and intervallength as well as the number call retry attempts and spacing.

Item Code Types

There are two basic types of item codes used in the Pulse Accumulator, Direct-read andConfiguration. The Direct-read items are mainly used to store information or to accumu-late readings. Except during the initial installation, these types of items are normally justread periodically to obtain the accumulated information. However, if needed, thesevalues may be changed by directly typing in new information from the keyboard.

Configuration items are used to configure or customize the Pulse Accumulator to pro-vide specific functions or features. Usually, these items require choosing an option froma list. When using MasterLink (version 3.50 or higher), the available options are pre-sented as text messages. However, if using an older version, the Raw Item Access fea-ture must be used to send a numeric codes to the items that need changed.

To gain Raw Item AccessLink to the Pulse Accumulator, then click: Setup\Advanced\Raw Instrument Access\RawItem Access.



Page 13

From the Raw Item Access window, enter the 3-digit item number and click Read. TheItem Value field will display the current code for that item if the status returns the mes-sage “Item Read Successful” with a green background

If a different value for that particular item is needed, change the value in the Item Valuefield and click Write. You can immediately click the Read button again to confirm theintended value was actually stored in the instrument.

Since the numeric codes for the Configuration items may not be readily apparent, use theitem list on the following pages to determine the required codes.

Installation

The Pulse Accumulator is designed to be a wall-mounted, battery-powered electronicrecorder of low-frequency pulses or switch closures. The internal 2400 baud modem isto be connected to a standard phone line to communicate accumulated reading to a hostcomputer system. Use the wiring diagrams on the following pages when making con-nections to the unit. Use the following steps as a general guide when installing the unit.

1) While viewing the front of the Pulse Accumulator assembly, rotate the case until thetwo case fittings are in the downward position.

2) Using the four mounting tabs (attached) and four screws (not included), attach theenclosure to a flat surface, usually a 1/2” thick piece of plywood.

3) Loosen the four screws in the corners of the lid. Remove the lid and set aside.

4) Install the battery pack into the battery compartment. Make sure the aluminum plateattached to the battery pack is positioned to the right before inserting. Plug the batterycable into Pulse Accumulator board at J4.

5) Route the wires (cable) from the remote switches or pulse output device through theright-side case fitting. Continue routing the wires through the right-side and top wirelooms. Connect the input switch wires to Pulse Accumulator board at TB2.

6) Route the phone wires (cable) through the left-side case fitting and left-side wireloom. Plug the phone cable into the modem board at J2.

7) Unplug the CMOS ribbon cable from the Pulse Accumulator serial port J5. Connectan MPA ribbon cable into J5 and the other end to a standard I/O serial cable. Plug theDB-9 connector of the I/O cable into the computer serial port.

8) Run MasterLink32 software and link the instrument. Use the “Set Instr. Date/Timevia Computer” selection in the Instrument menu to set the date and time in the instru-ment.

9) Use MasterLink32 to set the Input Pulse Value for Ch1 at item 098 and item 912 forCh2.

19


Page 18

10) If the Input Pulse Value is not listed at items 098 and 912, use Input Pulse Scaling atitems 114 and 913 to further define the pulse values. Example: If a switch closure fromthe meter is to represent 2 CF, set item 098 (912) to 1 CF and then set item 114 (913) to avalue of 2.0000. NOTE: Leave items 114 and 913 to 1.0000 if the proper pulse valuecan be selected at items 098 and 912.

11) Set item 092 for the desired Accumulated Volume unit-of-measure, i.e. CFx10, CCF,MCF, m3, etc. This setting will be applied to both Ch1 and Ch2 Accumulated Volumes.

12) Set the accumulated reading at items 002 and 910 to zero, or some other knownstarting value.

13) The Mercury Pulse Accumulator has the ability to apply FixedFactor correction tothe Accumulated Volumes. If FixedFactor is needed for either of both channels, changethe values at items 044 (Ch1) and 440 (Ch2) from 0.0000 to some greater value. Typi-cally, FixedFactor correction will be used to apply a pressure correction factor, or tem-perature correction factor or both. When FixedFactor correction is applied, items 000, or908 or both will advance from its default value of zero.

14) Set item 090 for the desired FixedFactor Volume unit-of-measure, i.e. CFx10, CCF,MCF, m3, etc. This setting will be applied to both Ch1 and Ch2 FixedFactor Volumes.

15) Use item 097 to set the desired number of digits displayed for Accumulated Volume.Use item 096 set to the desired number of digits displayed for FixedFactor Volume.

16) Set items 200 and 201 to the Site ID numbers assigned to this particular unit. Do notduplicate Site ID numbers for other units.



Page 19

17) In its default configuration, the Pulse Accumulator should be able to receive calls viaits internal modem. If the Pulse Accumulator is to also call into a host system, set item486 to “Yes”. Also set the following items to their most correct or most appropriatesettings:

333 Call-In Trigger334 Sched Call-In Date335 Sched Call-In Time336 Call-In Retry By:338 Sched Call-In Occurred339 Sched Call-In Phone Num493 Alarm Call-In Phone Num

18) If the Pulse Accumulator is set for Call-in (item 486 =”Yes”), then set the followingitems for their most appropriate settings:

495 Modem Retry Interval A 5 (Default)496 Modem Retry Interval B 1440 (Default)497 Modem Retry A Count 3 (Default)

19) If the Pulse Accumulator is connected to an external modem and the Power Controlfeature is to be used to periodically apply power to the modem then set the followingitems for their most appropriate settings:

490 Call-out Start Time 09 00 00 (Default)485 Call-out Stop Time 23:59:00 (Default)489 Call-out KeepAlive Time 0 (Default)488 Call-out RepeatInterval 0 (Default)487 Call-in Keep Alive Time 15 (Default)

20) When all items are set to their desired values, disconnect link and unplug the MPAcable from J5. Reinsert the modem ribbon cable into J5.

21) Reinstall the cover (lid). The lid is not a perfect square so be sure it’s rotated to thecorrect orientation.

NOTE: Tighten the four cover screws to 7.5 - 9.0 in. lbs. using a 1/4" flatbladescrewdriver. Also, overtightening the screws may damage the assembly and the useof a smaller screwdriver may damage the screws.

Power Control

Although not always needed, the Power Control feature (via A- & A+ at TB1) is used inconjunction with items 485 - 497 to apply power to a battery-operated external modem.The purpose of the Power Control feature to provide a time-schedule for limiting modemoperation (usually 10 to 60 minutes per day) as a means of extending modem battery life.If a wireless battery-powered modem were to remain powered continuously, the batteriesmay only last several days to several weeks. With Power Control, it’s possible to extendbattery life for months. In some situations, battery life greater than a year can be ob-tained. The trade-off is that the modem will only be available at certain time(s) duringthe day and only for the specified number of minutes.

When the Power Control feature is enabled, any call-in (Alarm or Scheduled)) will alsoactivate power for the modem and remain powered for the time interval specified at item487 (Call-in Keep Alive Time). The default setting of 15-minutes should be adequatetime to call back out to the unit to retrieve additional information following a call-in.

Pulse Accumulator Wiring

The drawing below will appear as a label on the inside of the Pulse Accumulator lid.This diagram indicates the recommended placement of field wires (or cables) broughtinto the Pulse Accumulator enclosure. Per the diagram, pulser wires from the meterswitches (or pulser output) are to be routed through the right-side case fitting and thenthrough the three gray wire looms mounted on the white battery plate. The wires are tocontinue through the single wire loom along the top before being routed down to TB2 onthe Pulse Accumulator board.

The telephone cable is to be routed through the left-side case fitting and then through thesingle wire loom along the left-side of the enclosure. Plug the phone cord into J2 of theMessenger Modem.

NOTE: To avoid potential damage from transient surges, when installing telephone andpulse input wires, keep the wires as short as possible and do not rest any access wires oneither circuit board.

Simplified Wiring Diagrams (with internal modem)

The following diagrams can be used to assist in the wiring of Pulse Accumulators duringinstallation. Either or both pulse channels may be wired to a remote Form-A (2-wire)switch or pulse output device. A 3.5 volts DC wetting voltage is provided by each PulseAccumulator input channel. Be sure to observe polarity if the pulse channel is to bewired at an active device, i.e. transistor-type output.

Note, for reasons of clarity, the case fittings are not shown in their proper relative posi-tions. See the diagram on the previous page for a more true representation.

Modem Call-in Configuration Items

333 Call-In TriggerCodes (0-3) to select the activity that will cause the instrument to make a call intoa host system.Select: 0-No Call-in - Default

1-Alarm Call-in Only2-Scheduled Call-in Only3-Alarm & Scheduled Call-in

334 Sched Call-In DateDate of the next scheduled call-in. When used, this parameter is normally incre-mented to the next calendar date by the host data collection computer so that afuture call-in will occur.Default = 01-01-04

335 Sched Call-In TimeTime of the next scheduled call-in. When used, this parameter is normally setonce and then reused for the next day’s call-in. However, the data collectioncomputer might make slight adjustments to optimize call throughput if schedul-ing a large number of units.Default = 12 00 00

336 Call-In Retry By:Codes (0-3) to select the retry strategy that is to be implemented by the instrumentbased on the following guidelines;

Host: Host is responsible for retrying failed call-ins after the initial handshake. If a call-in fails, the instrument is responsible for retrying only untilit receives the “+-+clralms” string from the host. Thereafter the instrumentwill not retry if the call is dropped. (It expects the host to do so.)

Instrument: Instrument is responsible for retrying failed call-ins. Foralarm call-ins, the call is considered successful when a sign-off commandis received at the instrument. For scheduled call-ins, the call is only con-sidered successful if the host writes a ‘0’ to item 338 (Scheduled Call-inOccurred). Until that happens, the instrument will call back after adropped call, or even after a sign-off command.

Select: 0 = Host - Default1 = Alarm: Host / Scheduled: Instrument2 = Alarm: Instrument / Scheduled: Host3 = Instrument (Most Preferred)

485 Call Out Stop TimeUser supplied time during the calendar day that Modem Power Control (enabledvia item 484) will end. Also see item 490 for Start Time.Default: 23 59 00

487 Call-in Keep Alive TimeUser selectable parameter to set the amount of time (in minutes) to leave thecommunication system (i.e. modem) powered up after an Alarm or Scheduledcall-in. The purpose of this feature is to allow for a follow-up call to retrieveadditional information (such as audit trail data) if needed.Default = 15 minutes

488 Call-out RepeatIntervalUser selectable parameter to set the amount of time (in minutes) to wait untilrepeating the Call-out Window set by the Call-out Keep Alive Time (Item 489).Note: When used, the value set in Item 488 must be greater than the value set inItem 489, otherwise the power control feature is disabled.Default = 0

489 Call-out KeepAlive TimeUser selectable parameter to set the amount of time (in minutes) that power is beapplied to an external modem, starting at the time-of-day set into item 490(Call-out Start Time). Note: Set items 488 and 489 to “0” (default) to disableCall-out power control. Call-in power control (item 487) will still provide mo-dem power for scheduled and alarm calls-inDefault = 0

Description

The Mercury Instruments Messenger Modem is a single channel, battery-operated, 1200/2400 baud, analog modem designed for the harsh environments of the natural gas indus-try. The modem board may be ordered with or retrofitted to existing Mini-AT, Mini-Max, ECAT, ER, Sentry and ERX instruments. The modem is also included as an inte-gral part of a standard Mercury Pulse Accumulator. Since the Messenger Modem re-quires very little power, it shares power from the instrument’s battery pack. Instrumentsconnected to a Messenger Modem may be called by host computer software (usuallyMasterLink or AutoLink) to remotely retrieve data, or the modem can call into hostcomputer systems that can answer and process incoming calls, such as Alarm-Link.

The Messenger Modem can also be installed into a separate enclosure as a stand-alonemodem assembly. Modem assemblies may also include safety barriers for pulse data,serial data and/or instrument power. Various power supply options are available for themodem assemblies and include; alkaline batteries, AC power and solar panels.

On-board DIP switches provide local configuration of various parameters, such as;

• Select carrier speed: 1200 or 2400 baud• Enable or Disable: Line Share/Line Surrender• Enable or Disable: Sleep Mode• Enable or Disable: Wake-up on serial data• Enable or Disable: Shutdown on low battery• Enable or Disable: Ring Detect• Select serial mode: RS-232 or CMOS

Verification (via MasterLink)

To verify that the installation of the integral modem was successful and the instrument is workingproperly, obtain a modem link with the instrument using MasterLink software.

• Start MasterLink and select Instrument | Establish Link on the main menu line• Click the appropriate check box in the Instrument Type above the Site List.• With the Site List dialog box open, click on Add and enter the required information• Insure the Site Name, Site Location, Site ID, Site ID 2, Instrument Access Code, Site Phone, and Modem Port are correct. (Modem Port must be set to “None”)• Click OK , then click EXIT when completed• Select Setup | Communications on the main menu line• Ensure Modem Connection Baud Rate is set to 2400 baud• Check to see if the correct Connector (Com Port) is selected• Try making a call to the remote site, even if the Modem Init String blank. If the call fails, most likely the host modem's profile is incompatible. Refer to Need Help on page 63 for further information on determining the Modem Init String• After the Modem Init String has been determined and inserted, select Instrument | Establish Link on the main menu line• Select the site entered above (click to highlight)• Click on the Modem button in the lower left corner Site List window to start the call• Follow the progress by watching the Traffic Light in the lower left corner of the MasterLink screen

Red indicates: Not Linked to InstrumentYellow indicates: Trying to Link to InstrumentGreen indicates: Established a Link to Instrument

• When the Traffic Light goes green, the status box to the right of the light will indicate the instrument type and the name of the site. If Site Unknown is displayed, the site ID numbers at item 200 & 201 did not match any of the Site List entries• Once linked, click on the red bell (upper right corner) to Display and Clear Alarms.• To complete the call, select Instrument | Disconnect Link. Verify the Traffic Light goes red

Need Help?

If you encounter problems while using the Messenger Modem, follow these steps:

HOST COMPUTER:

1. Make sure your computer, your modem and the cables that connect them are allworking properly.

2. Make sure you're not running software that may conflict with using thecommunication ports (infrared, PDAs, etc).

3. In MasterLink, go to Setup on the main menu line. Select Communications andensure that the Modem Connection section is correct.

Connector = usually Com-2 or Com-3 but may be something elseBaud Rate = 2400Modem Init String = modem specific *Dial Type = ToneDial Prefix = blank

* Usually requires a set of modem commands, specific to the modem being used

4. Use Terminal or HyperTerminal (or some other terminal communicationspackage) to check if communications between the host computer and modem canbe established. Test by typing “AT” and then press Enter. If the modem isworking, the on-screen response will be either "0" or "OK". If there is noresponse, check the program settings for proper baud rate and com port selection.Reset the modem to its factory defaults by turning the modem power off and thenback on, or by typing AT&f and then press Enter. The response should be "0" or"OK". Exit Terminal and start MasterLink.

Page 64

5. To establish a modem connection (Carrier Detect) with a Messenger Modem, Error Control in thehost modem must be set to Off.. The command(s) to turn off Error Control may vary depending onthe host modem’s manufacturer. To determine the proper Init String for the host modem, first useWindow’s Control Panel to verify that the driver for the host modem is installed. If your operatingsystem is greater than Windows98, then• Click Help on the MasterLink’s Main Menu.• Click About MasterLink32• Click the System Info button• After the screen refreshes, click the plus sign “+” next to Components• Click on Modem• After the right-side of the screen refreshes, find the line that contains Error Control Off• Note the command for Error Control Off• Combine the above command with “&f” (&f should always preceed any other commands)• Place the combined commands into MasterLink’s Setup|Communications Modem Init String field.

Below are several examples of modem init strings for both internal modems and external modems.Internal Modems: External Modems:&f &m0 &f &m0&f /n0 &f &k0 &q6&f /n1 &f +ES=1,0,1;

INSTRUMENT MODEM:

1. Ensure all instrument and modem cables are properly connected, e.g. phone line, battery powerand serial connections.

2. Ensure that the modems DIP switches are in the correct positions.

3. Check that the instrument’s baud rate is correctly set to 2400.

4. Unplug the modem's main power, wait 30 seconds and plug the main power back in. The modemshould cycle through its LED test. Wait for all the LEDs to go out before attempting to call theinstrument.
