HARDWARE OPTIONS

Design of theDANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER hardware allowsfor two input/output (I/O) configurations, including a one-board configuration or a two-boardconfiguration. The primary differences between the one-board unit and the two-board unit are thenumber of inputs and outputs each can handle. These two options provide for economy andflexibility when selecting an instrument for a specific installation. For example, an instrumentoriginally installed as a one-board unit can be upgraded to a two-board unit at a later time ifadditional capacity is needed.

The characteristics of the one-board and two-board configurations are outlined in the followingtable.

LIQUID METER PROVING

Meter proving, a procedure utilized in determining the accuracy of a liquid meter, is normallyapplied to Positive Displacement and Turbine meters. In meter proving the indicated volume offluid which passes through a meter is compared to the true volume measured in a pipeline proverof known size.

By comparing the true volume to the indicated volume, a meter correction factor, which isexpressed in the following formula, can be determined.

True volumeMeter Correction Factor =

Indicated volume

Provers are either uni-directional or bi-directional and measure non-interrupted liquid flowthrough Turbine or Positive Displacement meters. Inside the prover is a displacer, in the shapeof a sphere or piston, which is forced through the prover by line pressure. As the displacer travelsfrom one end of the prover to the other, it comes in contact with detectors mounted in the wallof the prover. The amount of displaced liquid between the two detectors is the true volume.

Flow from the main line is diverted into the prover causing the displacer to begin moving fromone end of the prover to the other. As the proving routine begins, pulses from the transmitter ofthe meter being proved are directed to a prover counter. The prover counter accumulates themeter pulses when the displacer actuates the first detector switch and then continues toaccumulate pulses when the displacer actuates the second detector switch. The prover counterthen ceases to accumulate pulses from the meter. At this point, the meter correction factor canbe calculated by using the following formula.

Volume displaced between switchesMeter Correction Factor =

Volume indicated by accumulated pulses

PROVING SEQUENCE

The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER with a single-boardconfiguration (MODEL 2521 series) handles proving for one meter, while the dual-boardconfiguration (MODEL 2522 series) handles proving for up to five meters. For furtherinformation, please refer to Drawing DE-15103 in the Appendix for a block diagramrepresentation of the proving sequence.

Automatic proving is setup to occur:

At a pre-selected time every day (e.g. contract hour)

Whenever operating conditions warrant meter proving, such as at changes intemperature, flow rate, density, etc.

For a combination of changing conditions and times

PROCEDURE SUMMARY

The following steps describe the sequence of events that theDANIEL INDUSTRIES MODEL2500 MICROCOMPUTER goes through in a proving sub-routine for a bi-directional prover.

1. The proof request is received by the unit.

2. The unit waits for the temperature in the meter to come within a certain numberof degrees of the temperature of the prover. The length of time the unit waits fortemperature stabilization and the proximity of the meter temperature to the provertemperature may be selected by the operator.

3. The unit sends a rotate command to the 4-way valve. If the 4-way valve does notrotate and report the proper status, such as "valve properly seated and sealed", theproof aborts.

4. When the 4-way valve is rotated, flow is diverted into the prover.

5. The displacer begins to move, which actuates the first detector, and the unit sensesthe first detector.

6. After the unit senses the first detector, it begins to accumulate pulses, metertemperature and pressure, and prover temperature and pressure. It also monitors

__________________________________________________________________________________________________________________________________________


________________________________________________________ Model 2500AUG 1995

the prover for seal integrity, and if seal integrity is lost during the proving run, theunit aborts the proof.

7. The unit continues to accumulate pulses, meter and prover data until the seconddetector is sensed. If the second detector is not sensed in the length of timedefined by an operator entry, the proof aborts.

8. The unit makes another pass through the prover as previously outlined in Steps3 through 7. For a bi-directional prover, one pass is considered half of a total run.

9. The unit will calculate a trial meter factor based on the total pulses, averagetemperatures, and average pressures of the total proving run.

10. The unit will runx number of operator-entry trial runs. The number of trial factorswill be compared, and if each of the trial factors are within a certain percentage,which is entered by the operator, of each other a valid proof has beenaccomplished.

11. If a valid proof is completed, the final meter factor is calculated from the averageof the data, which includes the pulses, temperatures, and pressures collected forthe x trials.

12. If the comparison in Step 10 was not valid, another trial is run and the lastxconsecutive trials will be tested as in Step 10. The unit will run up to ten trials toachieve the tolerance selected by the operator and will print both the results ofeach of the trial runs as they are completed and the results of the final meterfactor calculation. If the tolerance is not achieved after ten trials, the proof isaborted.

The previous steps described for a proving sub-routine for a bi-directional prover are the samefor a uni-directional prover, except that for a uni-directional prover:

Unit sends a launch command to the prover interchange

One pass constitutes a total proving run

As an example of when aDANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER isused in conjunction with a DANIEL INDUSTRIES PROVER RELAY ASSEMBLY, considera metering system with five turbine meter runs where each meter must be proved through a bi-directional prover at the contract hour. The steps involved in accomplishing thisfor each meterare as follows:

1. A request for proof of meter number one is received by theDANIELINDUSTRIES MODEL 2500 MICROCOMPUTER .

2. The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER controloutput associated with meter number one, "PROVE MTR #1", energizes relaynumber one of the DANIEL INDUSTRIES PROVER RELAY ASSEMBLY.

3. With relay number one energized, the pulses from meter number one are divertedto pulse input Channel Number One. This channel is dedicated to be the pulseinput for the meter to be proved.

4. The unit sends a rotate command to the 4-way valve.

5. Flow is diverted into the prover and the displacer begins to move.

6. When the senses that the first detector switch has been actuated, it beginsaccumulating the pulses from meter number one.

7. When the second switch has been actuated, the pulse accumulation stops, and asecond pass is run. For a bi-directional prover, one pass is considered half of atotal run.

8. The calculates a trial meter factor based upon the total pulses, averagetemperatures and average pressures of the total proving run.

__________________________________________________________________________________________________________________________________________


________________________________________________________ Model 2500AUG 1995

9. Typically five trials will be run, but the total number of trial runs is selected bythe operator. The five trial factors will be compared and if each of the five trialfactors is within a certain operator-selected percentage of each other, a valid proofhas been completed.

10. If a valid proof has been completed, the final meter factor is calculated from theaverage of the data collected for the five trials.

11. If the comparison in Step 9 is not valid, another trial is run and the last fiveconsecutive trials will be tested as in Step 9. TheDANIEL INDUSTRIESMODEL 2500 MICROCOMPUTER will run up to ten trials to achieve thetolerance selected by the operator. If the tolerance is not achieved after ten trials,the proof is aborted.

BASE25 EPROM CHANGEOUT

Before changing out any EPROMs, the operating parameters for theDANIEL INDUSTRIESMODEL 2500 MICROCOMPUTER must be recorded. This will help insure that setup remainsthe same after change takes place.

__________________________________________________________________

NOTE: The Numeric and Selection Operator Entries will contain mostof the special setup parameters.

__________________________________________________________________

The following steps describe the sequence of events for changing the EPROMs in theDANIELINDUSTRIES MODEL 2500 MICROCOMPUTER .

1. Discontinue power to the unit.

2. Locate the Base25 EPROM(s), which are installed in sockets U36 through U39on the CPU I/O PC board as shown in the following table.

Access to the board is obtained by unlatching the unit from the enclosure (seeunderneath the front panel) and sliding the unit out of the enclosure just farenough so that the left-hand board may be moved to the rear (see catchunderneath and toward the rear). The EPROM(s) are on the right board (CPU I/OPC Board) located in the sockets, which are marked U36 and U39.

3. Remove the old EPROM(s) as indicated in Figure 5.1.

4. Install the new EPROM(s) in the correct sockets, as specified in the followingtable.

U37 E800

U38 F800

U39 F000

__________________________________________________________________________________________________________________________________________


________________________________________________________ Model 2500AUG 1995

Ensure that all pins of the EPROM(s) are installed correctly with the locator notchon the EPROM lining up with the socket notch, regardless of the orientation onthe EPROM labels.

5. If the Model 2500 is a two-board unit (Model 2522), remove the old EPROM, ifpresent, and install the Memory D800 EPROM into socket U44, as shown inFigure 5-2. Ensure that all pins of the EPROM(s) are installed correctly with thelocator notch on the EPROM matching the socket notch, regardless of the labelorientation on the EPROM(s).

6. To make sure the Random Access Memory (RAM) has no extraneous information,on the CPU I/O Board, briefly short pin 14 to pin 28 on U34 and U35. This isillustrated in Figure 5-1. If theDANIEL INDUSTRIES MODEL 2500MICROCOMPUTER is a two-board unit, briefly short pin 14 to pin 28 on U24,U28, and U38 of the I/O Expansion Board as shown in Figure 5-2.

7. After installation is completed, close up the unit and apply power. The front panelLCD screen should display the following message:

AWAITING CONFIGP2 B2400 ID001

8. Download the desired application program and setup the various operatingparameters.

For further information, please refer to the DANIEL INDUSTRIES MODEL 2500INSTRUMENTATION SYSTEM USER REFERENCE MANUAL (Daniel P/N 3-9000-591).

CALIBRATION

Since rate current outputs are calibrated before theDANIEL INDUSTRIES MODEL 2500MICROCOMPUTER is shipped from the factory, repeating the procedure should not benecessary, unless it is determined that output readings have varied over long periods, or errorsare found in the output units.

TheDANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER application program shouldbe installed in the unit before a rate current output calibration is performed.

__________________________________________________________________

NOTE: Reference should be made to the application, which is specific tothe unit, in order to determine the names of the current outputs.

__________________________________________________________________

A rate current output calibration requires:

Long-shank screwdriver

Fluke Model 8060A Digital Multimeter or equivalent, which has been calibratedto a traceable standard

The following steps describe the sequence of events that must be followed in order to performa bench calibration.

1. Disconnect the primary power source or press Power Switch S1 located on theoutside of the termination enclosure. If a power supply is attached at the rear ofthe enclosure, turn the switch off.

2. Release the catch underneath the display and slide the unit out of the enclosure.

3. Pull out the left-side panel covering the CPU Expansion board.

4. Remove the four screws attaching the plate at the right rear of the enclosure togain access to the rear termination board to allow access to the output terminalsfor rate current outputs Nos. 1 and 2.

A. Objective

The object of this proedure is to configure the Hayes Accura 336 Modem for usewith the Model 2500 units. All of the configuration options are determined byparameters stored in nonvolatile memory. There is one preconfigured factoryprofile that is stored in ROM but will be modified by this procedure. Whenpower is first applied to the modem, the new profile will be loaded as the activeprofile and will be stored as profile “0” in nonvolatile memory.

B. Equipment

1 IBM PC Compatible with Smartcom for Windows (provided with modem)or equivalent communication software.

1 RS-232 cable with a 25 pin male connector to a 9 or 25 pinmale orfemale connector, depending on your PC's serial port connector.

C. Setup

1. Attach the RS-232 cable to your PC and Modem and connect the powercable to the modem.

2. Power up the modem and the PC.

3. If you will be using the software provided with the modem, start Windowsand then the Smartcom for Windows program. Refer to the HayesCommunications Guide for operating instructions.

4. If you will be running from the DOS environment, execute yourcommunications program.

D. Configuration Procedure

1. Once the Smartcom program is operating, select the Direct Connect optionfrom the Connection menu.

2. If you are using any other communications software, refer to theinstructions manual to set the modem into a command state.

3. Type the following commands:

The 2500 Series computer has a designed in feature which allows one of its serialcommunication ports (Port 1) to be configured to be compatible with several of thecurrent standard electrical communications interfaces. The standard electrical protocolswhich are supported by the 2500 are:

RS-232C* RS-422/RS-485 Two-Wire* RS-422/RS-485 Four-Wire

RS-485

This document is to be used to modify communications Port 1 to be compatible with oneof these protocols.

It should be noted that the modification from an RS-422 to an RS-485 on alpha boardsimplementation requires the removal of U25 and U26 (a 26LS32 and a 26LS31respectively) and the installation of a DS3695 RS-485 transceiver in location U40. Theseconversions are shown in tabular form below.

Please note that the standard U.S. version of the CPU I/O Board (P/N 3-2500-025) comeswith the RS-422 chip set installed and that the Euro version of the CPU I/O Board (P/N3-2500-026) comes with the RS-485 chip installed. Also please note that on Rev. P2boards for the RS-232 implementation connect E46 to E51 and E47 to E50 instead of E46to E47 and E50 to E51.

CAUTION - The chips for the RS-422 implementation cannot be installed in a boardwhich has the RS-485 transceiver installed. If this precaution is not observed, the RS-422chip set will be destroyed.

*Not applicable for "BETA" PCA’s.
