SECONDARY DATA SCREENS

Each of the top-level menus has a secondary level consisting of one or more screens. Each screen is divided into one or more fields where data may be entered or information displayed. Access to data entry is dependent on the following:

DATA FIELD TYPE:

Some fields are for display only and data entry is not necessary (e.g. DIAGNOSTICS and FLOW RATE).

PASSWORD PROTECTION:

The LCR-II has a user-definable password that allows the system to be locked. This feature authorizes a supervisor to limit access to certain fields. An operator can still view all data fields whether the unit is locked or unlocked. Data entry in general system set-up functions (e. g. NO-FLOW TIMER and

PRESET TYPE) are still accessible if the system is locked.

SELECTOR SWITCH:

The multi-position Selector Switch on the front of the LCR-II™ has a CALIBRATION position that is accessed by removing a Weights & Measures sealable plate. This allows data entry in the metrologically significant fields (e. g. COMPENSATION TYPE, TEMPERATURE PULSES/UNIT and others).

When a secondary menu is entered by pressing the ENTER key, the cursor will be positioned in the top line of the first field. Pressing

i will cause the cursor to move to the next field.

Repeatedly pressing secondary menu screen will be displayed. The cursor will be in the first field. Af ter the last field of the last screen, the cursor returns to the top line of the first field of the first screen.

NOTE: Pressing the "M#" key scrolls forward to the next secondary menu. Pressing "M1" returns the display to the toplevel menu from any secondary level menu.

The cursor indicates if data can be entered or changed in the field below it. If the cursor is flashing, pressing ENTER will move the cursor to the second line in the field and data may be entered or changed. In some cases, data is entered using the keypad. In other cases, data is entered by selecting entries using the of the field indicates that a scroll list is used for the field. In fields that have a "?", a "YES" or "NO" response is selected. Information that is entered through the Lap Pad or selected from a menu of choices is stored in the LCR-II by pressing ENTER. The cursor also moves back to the top line of that menu screen.

Menu maps of the screens accessible in the system are located in Appendix D on pages 50-57.

BEFORE GETTING STARTED

• Make sure that the Lap Pad or other data entry device is connected to the LCR-II register as described in the LCRII Installation Manual.

• When proving the LCR-II system, follow the pre-test and inspection procedures established by Weights & Measures authorities. The primary indicating and recording element on a vehicle-mounted LCR-II is the 6-digit liquid crystal display.

• Weights & Measures inspectors are responsible for determining if the truck metering and recording elements of the system are within tolerance. To make this determination, the system should be tested under normal conditions.

• The LCR-II is pre-programmed with common values for many of the programmable parameters. These values should be checked to ensure that they fit the specific requirements of the given installation. Detailed instructions for checking and changing these values follow later in this publication.

• Changes cannot be made to metrologically significant data without first removing the Switchplate and its associated Weights & Measures seal. The security level for each of the programming screens is defined in the following table:

NOTE: This table applies to the lower line of the Lap Pad display only. The upper line cannot be edited.

STEP 1: REMOVE THE LCR-II SWITCHPLATE

• Remove the lead seal and wire assembly from the LCR-II Switchplate (if previously sealed by Weights & Measures authorities).

• Remove the four screws that secure the Switch Plate over the red Selector Switch located on the front of the LCR-II, and remove the plate.

• Rotate the Selector Switch counter clockwise to the 6 o'clock (CALIBRATION) position to permit access to all programming fields (except FACTORY).

MULTI-POINT CALIBRATION

Multi-point calibration allows a flowmeter to be used over a wide range of flow rates without experiencing a loss in measurement accuracy dueA to the shape of the meter curve (usually at low flow rates). Af ter determining the inaccuracy of the meter at a variety of flow rates and inputting that information into the LCR-II multi-point calibration table, accuracy corrections are then continuously made by the LCR-II based on the measured flow rate. There are two ways to obtain the information necessary to load the multi-point calibration table:

1. Manufacturer's data supplied with the meter can be entered directly.

2. The meter can be field calibrated by proving at various flow rates.

1. MANUFACTURER'S DATA TECHNIQUE Step 1:

Go to Screen 7 of PRODUCT CALIBRA TION. From the manufacturer's data sheet showing the accuracy at various flow rates, enter into PT^1 the flow RATE and the delivery %ERROR corresponding to the maximum flow rate of the meter.

Step 2:

Select up to nine additional points from the manufacturer's data sheet to characterize the remainder of the meter's accuracy curve and enter this data into PT^2, PT^3, etc., respectively, in descending order by rate. (While it is not necessary to enter the selected points in a specific order , it is desirable to do so because the LCR-II will re-sort the data and arrange it in descending order by rate when it is APPLIED.) T o enter negative %ERROR values, first enter the number , then press the "*" key to display the "-" sign. Errors that can occur during multi-point table data entry include:

DUPLICATE FLOW RATE ERROR

The same flow rate value was entered twice.

RANGE ERROR

A %ERROR outside the ±3.0% limit was entered.

POINT SELECTION TIPS:

• Because the LCR-II uses a piece-wise linear interpolation method of correction, it is desirable to use more data points along segments of the accuracy curve that have the greatest curvature (typically in the low flow rate region).

• Where the meter curve already approximates a straight line (in the high flow rate region), use fewer of the available points.

Step 3:

Set the LINEAR^ field to APPLIED and enter it. This puts the linearizing algorithm into effect. If the error message ADJACENT POINTS OUT OF 0.25% RANGE is displayed, APPLIED will not take effect and the points will need to be reselected to ensure that no two points adjacent to each other are more than 0.25% apart in %ERROR.

Step 4:

Field prove the meter at the normal high flow rate of the system. Adjust the PULSES/UNIT in Screen 3 of the PRODUCT CALIBRA TION menu by entering the actual PROVER QTY (see Page 19) to obtain accuracy within tolerance limits.

MULTI-POINT CALIBRATION CONTINUED

Step 5:

Refill the prover at the same flow rate as Step 4 to verify that the meter remains within tolerance limits. Assuming that the dat a provided by the meter manufacturer is correct, and that proper technique was used for selecting and entering the multi-point table, it should be possible to fill the prover at any flow rate within the linearized range and obtain an error near zero.

2. FIELD PROVING TECHNIQUE

When the meter's accuracy is not provided by the manufacturer, points to enter into the multi-point calibration table need to be determined by field proving at various flow rates.

Step 1:

Start a proving run of the meter while viewing PRODUCT CALIBRATION - Screen 3 at the normal high flow rate of the system while the LINEAR^ field is in the SETUP mode. With the prover full, press

PRINT and adjust the PULSES/UNIT by entering the actual PROVER QTY (see Page 22).

Step 2:

Step 3:

Step 4:

Go to of PRODUCT CALIBRATION - Screen 7. With PT^ set to 1 and LINEAR^ still set to SETUP, start a new prover run at the same flow rate as Step 1. During prover filling, note the maximum RATE that is displayed. When the prover is filled, press PRINT. Advance to PRODUCT CALIBRATION - Screen 8. Enter the volume delivered to the prover in PROVER QTY. The %ERROR field will then display the calculated error for that rate. This should be a very small value since Step 1 "zeroed" the meter at the same rate. Return to PRODUCT CALIBRA TION - Screen 7 and enter the maximum flow rate observed during prover filling in RATE for PT^ 1.

With PT^ set to the next point and LINEAR^ still set to SETUP, start a prover run at a different flow rate. During prover filling, note the maximum RATE that is displayed. When the prover is filled, press

PRINT. Advance to PRODUCT CALIBRATION - Screen 8. Enter the volume delivered to the prover in PROVER QTY. The %ERROR field will then display the calculated error for that rate. Return to PRODUCT CALIBRA TION - Screen 7 and enter the maximum flow rate observed during prover filling

in RATE for that PT^.

Continue proving at other flow rates using additional PT^ numbers following the same procedure as Step 3. A minimum of three points is recommended (high, medium and low flow) to obtain a good fit to the curve. All ten points can be used to obtain optimum results. Any unused points should be left at

RATE=0 and %ERROR=0.

Step 5:

Set the LINEAR^ field to APPLIED and enter it. This puts the linearizing algorithm into effect. The LCR-II will re-sort the multi-point table and display the points in descending order by RA TE. Do not be alarmed if the data changes in a given PT^. If the error message ADJACENT POINTS OUT OF 0.25% RANGE is displayed, APPLIED will not take effect and more points will need to be added to ensure that no two points adjacent to each other are more than 0.25% apart in %ERROR.

Lap Pad Basic Operation

PRESET DELIVERY WITH A LAP PAD

If a terminal or Lap Pad is attached to the LCR-II serial port, it can be used to preset the delivery volume. The product number is selected in the first screen of the DELIVERY & PRESET menu and the GROSS or NET PRESET is entered in the third or fourth screen. (NOTE: The NET PRESET screen will only be displayed if the product being delivered is temperature compensated). If the Selector Switch has been left in the RUN position, a delivery will begin when the START key is pressed on the Lap Pad or terminal. Product will then be delivered until NET or GROSS PRESET amount is reached, at which point the delivery will be halted.

A delivery ticket will be printed:

• As soon as the preset volume is reached and if CLEAR or RETAIN has been selected

• If the PRINT key is pressed

• If the NO-FLOW TIMER times out If both NET and GROSS PRESETS are non-zero, the delivery will end when the lower of the two is reached. If the preset type is set to MULTIPLE, the valve will close when the preset amount is reached. The operator can

continue that delivery, making additional "drops" of the same quantity or preset amounts. The preset amount can be changed between drops. The delivery ends when the PRINT key is pressed or the Selector Switch is placed in the PRINT position. The delivery ticket will show the total GROSS and/or NET volume delivered. If the NO-FLOW TIMER is not set to 0, the delivery will end if the timer times out between drops.

Preset may also be controlled directly from the LCR-II. This feature is described on Page 34. The DELIVERY & PRESET menu group is the only one needed to make preset deliveries.

LCR-II Troubleshooting Guide

To comply with Weights & Measures requirements, it is necessary to start and stop each delivery with a fully packed hose. Normally , this will be the case. However, there are times where the hose is not fully packed (e. g. after a preset delivery). As such, the hose must be packed and the register zeroed prior to making the next delivery.

NOTE: This procedure will not work for an empty or dry hose. If more than 1 gallon or 5 litres of liquid is required to pack the hose, a delivery ticket must be printed.

To pack the hose at the start of a delivery:

1. Turn the Selector Switch to RUN. DO NOT OPEN THE HOSE NOZZLE. The display will reset and the

solenoid will open the valve, packing the hose.

2. When the display has stopped incrementing, the hose is packed.

3. Then the Selector Switch to STOP. This will de-energize the solenoid and close the valve.

4. Turn the Selector Switch back to RUN. The display will reset to zero, and the solenoid will energize again

and open the valve.

5. Open the hose nozzle and begin the delivery.

6. The Selector Switch can only be turned to STOP one time per delivery, at the start of the delivery, to pack

the hose.

7. To end a delivery with a packed hose, complete the delivery by closing the hose nozzle prior to turning the

Selector Switch to STOP. If making a preset delivery where the solenoid closes the valve prior to the hose nozzle being closed, the above noted procedure to pack the hose must be conducted on the next delivery .

Appendix C - Error Messages

The LCR-II was designed to perform diagnostic analysis of problems as they occur. If an error should occur, one of the following messages may be displayed on the Lap Pad or printed on a Diagnostic Ticket (see troubleshooting section). The list below explains the error message and any possible corrective action. The LCR-II was designed to handle most foreseeable problems on its own. Consequently, if the suggestions listed are not successful, the assistance of a trained authorized Liquid Controls service provider is recommended.

RUN TIME MESSAGE LIST

These messages may be displayed on the Lap Pad if an error occurs while the system is running.

FLASH CRC FAILURE

The CRC stored with an LCR-II data block indicates the data or CRC has been corrupted. A "REBUILD" operation could possibly fix the problem. If not, try "CLEAR ALL". If that does not work, hardware may be the problem and the unit should be returned to Liquid Controls for more analysis. NOTE: Before performing a "CLEAR ALL" operation, print a calibration ticket.

FLASH WRITE FAILURE

A failure was detected while a data block was being written to the flash memory. See the resolution suggestion under FLASH CTC FAILURE.

FLASH NOT INITIALIZED

This error indicates that a "CLEAR ALL" or "REBUILD" has been attempted without the Selector Switch in CALIBRATION position.

RANGE ERROR

The data entered is not within the legal range limits for the field being changed.

DUPLICATE FLOW RATE ERROR

This message only appears when setting up multi-point calibration. When calibrating a multi-point meter, the linearization point s must all have unique flow rates. This message is displayed when a flow rate being entered is already used on another point.

ADJACENT POINTS OUT OF 0.25% RANGE

This message only appears when setting up multi-point calibration. When calibrating a multi-point meter, adjacent linearization points must be within a 0.25% correction of each other. To avoid this error, select an additional flow rate and correction factor between the two points. More than one additional point may be required. Adjacent flow rates entered for linearization cannot have their percent error fields further than 0.25% apart.

COUNTER TEST IN PROGRESS…

A delivery has been started and the counter test is in progress. When the test is complete, flow will start. This is not an error condition.

START ENABLED - SWITCH TO RUN TO BEGIN DELIVERY

The START button on the Lap Pad was pressed but the Selector Switch was not in the RUN position. When the switch is put in the RUN position, the delivery will begin.

Appendix C - Error Messages

DIAGNOSTIC MESSAGE LIST

If an error occurs during a delivery , the message "*F AUL T : PRINT DIAGNOSTICS TICKET*" will appear on the delivery ticket. The appropriate message below is then printed on the diagnostic ticket if an error has occurred. A diagnostic ticket is printed by loading a ticket into the printer and then moving the Selector Switch to the SHIFT PRINT position for less than two seconds.

PREVIOUS DELIVERY TICKET PENDING

A new delivery was attempted but the previous delivery ticket was not printed in its entirety. The PRINT button should be pressed on the Lap Pad, or the Selector Switch should be placed in the PRINT position. Once the previous delivery ticket is printed, a new delivery can begin.

ROM CHECKSUM ERROR

This message indicates that the program memory space of the LCR-II has been corrupted. If this error occurs, the unit must be re-flashed with the control software before any deliveries can be made.

TEMPERATURE ERROR

This message appears if the temperature circuit returns an error or if the temperature calibration data is in error. Check the temperature probe and it s connections. A broken temperature probe wire is the most common cause of this error. See the troubleshooting section.

VCF DOMAIN ERROR

This message indicates that the calculated temperature falls outside the allowable range for the current compensation parameter . V erify that the correct product compensation type (see PRODUCT SET -UP) is being used.

PULSER FAILURE

This message appears if the number of pulser faults exceeds the allowable amount. The number of allowable faults is determined by an equation and cannot be changed. A maximum of 5 times the number of pulses required for the least significant displayed digit OR 0.1% of the pulses generated for the current delivery are allowed. Pulser faults generally occur in high vibration environments or when the flow rate is highly throttled. Liquid Controls is not responsible for pulser failures caused by excessive system vibrations. See the troubleshooting section.

METER CALIB ERROR

A product that has not been calibrated has been selected for delivery . Select a valid calibrated product.

PRESET STOP

This message appears if the delivery has stopped due to a GROSS or NET PRESET amount being reached. This is not an error condition.

NO FLOW STOP ERROR

This message appears if the NO-FLOW TIMER has expired, causing the current delivery to be terminated. This is not an error condition. Entering "0" for this parameter in the GENERAL SET-UP menu can turn off the NO-FLOW TIMER, however, this results in a system that is less secure.

STOP REQUESTED

This message appears when a STOP command has been sent to the LCR-II system to pause the delivery. STOP can be activated from the Selector Switch, Lap Pad, or a Terminal. This is not an error condition.

DIAGNOSTIC MESSAGE LIST CONTINUED

DELIVERY END REQST

This message appears when a PRINT command has been sent to the LCR-II system to terminate a delivery. PRINT can be activated from the Selector Switch, Lap Pad, or a Terminal. This is not an error condition

POWER FAIL ERROR

This message appears when a delivery was ended due to a loss of input voltage. Check the power supply and wiring to the LCR-II. Check the in-line fuse. See the troubleshooting section.

PRESET ERROR

This message appears when a flash memory error is detected during a delivery when accessing any of the fields used by PRESETS. This includes GROSS PRESET amount, NET PRESET amount, S1

CLOSE VALUE, remaining PRESET amounts, the PRESET type, or PRESET ALLOWED fields.

TERMINAL NOT CONNECTED

This message appears when a Terminal or Lap Pad is disconnected during a delivery. Check the cables and connectors for broken wires and loose connections.

Appendix C - Error Messages

CHECK PRINTER AND CABLE

This message appears when the printer is not responding. This can be the result of a faulty data cable, power cable, or LCR-II circuit board failure. The most common cause is that a ticket is not in place in the printer. The Epson Slip printers have a built in photo eye to detect if a ticket is in position.

DATA ACCESS ERROR

This message appears when a flash memory error occurs.

DELIVERY TICKET PENDING

This message appears when a delivery has been terminated but a delivery ticket has not been completely printed. When this occurs, it is assumed that the delivery is still active. No fields can be changed until the delivery ticket has been entirely printed. Load a ticket into the printer and print the delivery ticket by moving the Selector Switch to PRINT, or by pressing PRINT on the Lap Pad.

SHIFT TICKET PENDING

This message appears when a shift ticket is being printed. This is not an error condition.

Appendix E - Weights & Measures Prover Guide

This guide has been created to clearly convey the method for proving a meter system equipped with a LectroCount LCR-II electronic register without the use of a Lap Pad or external data entry device. This guide will only cover the software features of the LCR-II in the calibration/prover mode.

NOTE: The following method provides a means to check the overall meter accuracy as well as adjust the meter's "k-Factor". The k-Factor moves the entire meter accuracy curve either up or down. If it is believed that the meter curve itself may have changed (e.g. when a measuring chamber is replaced), and it is desired to use and/or change multi-point calibration, a Lap Pad or other data entry device must be used per the Set-Up & Operation Manual.

The LCR-II must initially be set-up and calibrated using a Lap Pad or data entry device. Once this has been accomplished, the LCR-II can be proved without using such a device. Only products with a valid pulse/unit (k-Factor) can be recalibrated using this feature.

1. Remove the Switch Plate cover.

2. Turn the Selector Switch to the calibration/prover position. This is accomplished by rotating the Selector Switch counter-clockwise to the 6:00 position.

3. The display will show "000.000". This represents the delivered volume as recorded by the register. The current calibration settings will be printed on a ticket.

4. Press the SELECT button one time. The display will show "Prod 1". Press INCREASE to select from the programmed products (Prod 1 to Prod 4). Only products that have been previously set-up and calibrated will be displayed. If only one product has been calibrated, only one Prod # will be available.

5. When the desired product number is displayed, press SELECT. The display will advance to Flowrate, "F 0.0".

6. Press SELECT and the display will advance to Temperature, " 42.5 ºF". If a temperature probe is not installed, the display will show "999.9 ºF".

7. Press SELECT and the display will return to "000.000".

8. To start a delivery, press the INCREASE button one time. This takes the display through an "all segments and blanks" test and starts a delivery by activating the solenoid valve controls. (All segments and blanks: "8.8:8.8:8.8"). If the register display remains at zero, open the hose nozzle and begin to fill the prover. If the register did not remain at zero (the hose needed to be packed), leave the pump running and press the INCREASE button to stop the delivery. Then press the SELECT button until the display digits no longer flash. Press the INCREASE button on the LCR-II to start the actual delivery with a packed hose. Open the hose nozzle and start to fill the prover.

9. Once the prover is filled to the desired volume, close the hose nozzle and press the INCREASE button on the LCRII to deactivate the solenoid controls and end the delivery.

10. If it is determined that no change to the meter k-Factor is desired, turn the Selector Switch clock-wise to exit the calibration/prover mode. Proving is complete. If it is determined that a change to the meter k-Factor is desired, use the INCREASE and SELECT buttons on the LCR-II to adjust the value on the register to match the volume of the prover. The following page contains an example.

Appendix E - Weights & Measures Prover Guide

k-Factor Adjustment Example:

Presume that the LCR-II register displayed "101.235" Units and the prover volume was determined to be "100.593" units at the end of step 9. ("Units" represents the units of measure as designated on the front cover of the LCR-II.)

When INCREASE is pressed in Step 9 above, the left most digit of the LCR-II register will be flashing on and off, indicating that it can be changed. To change this value, press INCREASE to scroll through 0-9. The display digits will wrap around to 0 after 9 has been reached. When the desired value for the first position has been reached, press SELECT and the next digit to the right will flash on and off. In this example, no adjustment to the first digit is necessary .

The second digit also does not require adjustment, so press SELECT to advance to the third digit. The third digit, "1", will be flashing on and off and needs to be changed to 0 in order to match the prover volume. Press INCREASE to scroll through the digits until "0" is displayed. Press SELECT to accept that value and advance to the next digit, "2".

Press INCREASE until the number "5" is displayed. Press SELECT to advance to the next digit, "3". Continue in this fashion until all the digits on the display are adjusted to the prover volume: "100.593". When this is complete, none of the digits will be flashing on the display . A new k-Factor is recorded by the LCR-II. Turn the Selector Switch clock-wise to exit calibration/prover mode.

If a number is entered in this example that results in an unacceptable k-Factor , the display will show "Error". When this occurs, press SELECT and return to Step 7 and conduct another prover run.
