Loop Leader PD6622/4 Loop-Powered Rate/Totalizer Instruction Manual

Introduction

The Loop Leader PD6622 and PD6624 are loop-powered, 1/8 DIN flow rate/totalizers designed for demanding process control applications. The four front panel buttons make setup and programming of the meter simple and intuitive. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, and optional bargraph display (PD6624) provide a clear and attractive presentation of the process. The units of measure can be changed as needed (e.g. gallons/second to liters/second) without the need to re-scale the meter.

The dual-line display can be customized by the user to operate in such a way as to satisfy a specific application. Typically, the top line is used for the rate while the bottom line is used for the total, grand total, or engineering units. Three programmable function keys and a digital input come standard and allow the meter to be customized for use in specialized applications.

All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features.

The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The Loop Leader loop-powered rate/totalizer is built in a shallow-depth case with a NEMA 4X/IP65 front and features loop-powered backlighting and a wide -40 to 167°F (-40 to 75°C) operating temperature range. It doesn't matter if it's indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.

Setting Up the Input Signal (INPUT)

It is very important to read the following information, before proceeding to program the meter:

 The meter is factory calibrated prior to shipment to display 0-100 gal/s, which corresponds to the 4-20

mA input. The calibration equipment is certified to NIST standards.  A calibrated signal source is not needed to scale the meter. Enter the Input menu to scale the meter to display the 4-20 mA input. The input is capable of accepting

any signal from 4 to 20 mA.

When the desired unit of measure is not available, a custom unit may be programmed. Select the CUSTOM menu in order to enter a custom unit name.

Text values are set using the Right and Up-Arrow buttons. Press Right-Arrow to select next character and Up-Arrow to increment character value. The selected character will flash. Press and hold the Up or

Right-Arrow buttons to auto-increment or decrement the character. Press Enter to accept the character.

Notes:

 Press and hold the Right Arrow while no character is being edited to erase all characters to the

right of the flashing character

 Press and hold Up or Right Arrow to auto-increment or decrement a selected character.

 All text values, including tags and alarm messages, are set in a similar fashion.

Scaling the 4-20 mA Input

The 4-20 mA input can be scaled to the appropriate values for a given application. The 4-mA input (input

1) should have a corresponding display value (display 1) which represents the low end of the process value range being measured by the transmitter. Likewise, the 20-mA input (input 2) should have a display value (display 2) which represents the high end of the process value range.

For example: If the meter is setup to accept a 4-20 mA input and display the flow of a pipe whose rate of flow is between 0 and 100 gal/s, the transmitter would send a 4-mA signal when there is zero flow and a 20-mA signal when there is maximum flow. The meter should be programmed to interpret these inputs on a display range of 0-100, so that at 4-mA the meter will display 0 and at 20-mA the meter will display 100.

Processes which require a non-linear scale can be accommodated using the linear (LINEAR), exponent (EXPONENT), and square root (SQROOT) functions available in the Advanced menu. See Signal Input Conditioning Functions (FUNCTION) on page 32.

A signal source is not needed to scale the meter; simply program the inputs and corresponding display values.

Setting the Display Features (DISPLAY)

The meter’s display functions may be programmed using the Display menu. This menu consists of the following submenus: Units, Decimal Point, Comma, Bargraph (PD6624 Only), Top, and Bottom.

Changing the Units (UNITS)

It is possible to change the display units without the need to re-scale the meter. When selecting a new unit from within the DISPLAY menu (e.g. changing from gallons/sec. (GAL/s) to liters/sec. (L/s)), the meter will automatically convert the display values to display the new unit. Enter the UNITS menu, select a new unit of measure from the list of predefined units, and press the Enter button. If entering a custom unit (CUSTM), a custom conversion factor will need to be entered.

Changing the Decimal Point Location (DEC.PT)

The decimal point may be set with up to seven decimal places or with no decimal point at all. Pressing the Right Arrow moves the decimal point one place to the right until no decimal point is displayed, and then it moves to the leftmost position. Pressing the Up-Arrow moves the decimal point one place to the left. The decimal point location is set independently for the rate, total and grand total.

Enabling or Disabling the Comma on the Bottom Display (COMMA)

The bottom display is set to show a comma separating the thousands and millions place by default if a numeric value is being displayed. This feature can be disabled or enabled using the Comma menu.

Programming the Bargraph (PD6624 Only)

The PD6624 comes equipped with a bargraph display for applications where a visual representation of

the rate, or total’s percentage of full scale is desirable. This feature can be changed to represent either

rate or total, or disabled, using the Bargraph menu (BARGRAPH). If the bargraph is set to represent total, the total full scale will need to be set.

Open Collector Outputs (OPEN COLLECTR)

The meter is equipped with two NPN open collector outputs that may be set up for pulse outputs, alarms, timed pulses, total reset, or turned off. Pulse outputs can be set to transmit the rate, total, or grand total. Output 2 may be used to generate a quadrature output based on the other open collector output. An output test mode is also selectable to generate pulses at a constant programmable frequency. Alarms are available based on the PV value or the digital input. The alarm status will show on the display even if the output is not wired. A timer output turns the open collector on and off at a specified frequency to act as a timer. A total reset output generates a pulse whenever the total is reset, regardless of the reset method used. The On time is programmable between 0 and 9,999 seconds. The output may be disabled by selecting DISABLE.

Pulse (PULSE)

Pulse outputs may be assigned to output the rate, total, or grand total at a programmable factor. The factor determines the number of pulses per second which should be generated per unit of measure. For example, if the meter display shows 100 gallons and the factor is set to 2, the number of pulses generated per second would be 200. The maximum frequency is 250 Hz. Setting output 2 to quadrature will duplicate the other open collector output, but lag by 90 degrees out of phase. The other output should be programmed as desired for the quadrature output function, and must be a pulse (PULSE) output selection. The quadrature maximum frequency for both outputs is 125 Hz.

The TEST option will output a fixed number of pulses per second based on the FREQ value entered.

Alarm (ALARM)

Alarm outputs may be assigned to the rate, total, grand total, or the digital input. When assigned to the rate, the alarm may be set as either a high alarm or a low alarm. Alarm actions (AUTO, AUTO.MAN, LATCH, L-CLEAR) determine how and when the alarm should be reset. They operate as follows:

 Automatic (AUTO): Alarm will reset automatically once the alarm condition has cleared.  Automatic/Manual (AUTO.MAN): Alarm will reset automatically once the alarm condition has

cleared but can also be reset using the Enter button (or whichever function key is set to acknowledge).

 Latching (LATCH): Alarm will not reset automatically even if the alarm condition is cleared. Press

the Enter button at any time to clear the alarm.

 Latching w/ Clear (L-CLEAR): Alarm will not reset automatically. Press the Enter button once

the alarm condition has cleared to reset the alarm.

If the alarm is set to rate, a set and reset point must be programmed. The set point is the display value at which the alarm will turn on and the reset point is the display value at which the alarm will turn off. If the set point is lower than the reset point, the alarm will be a low alarm; if the set point is higher than the reset point, the alarm will be a high alarm. If the alarm is set to total or grand total, only a set point needs to be programmed. The digital input alarm will engage whenever the digital input is triggered. For all alarms, a delay before the alarm is turned on or off may be set, as well as a failsafe feature which will inverse the on/off programming. Alarm states will be displayed on the meter even if no open collector output is physically connected. The alarm indicator (!) will display as well as optional red LED backlight, flashing rate, total, or grand total value (rate, total, or grand total alarms only), and a programmable alarm message.

Timer (TIMER)

The timer output produces a constant width pulse at a constant frequency. Program the Off Delay (OFF.DLAY) from 1 second to 99 hours 59 minutes and 59 seconds. This is the time it takes from selecting START to turning on the output and for how long the output is off in continuous mode.

Program the On Time (TIME) for the active low pulse from 1 second to 99 hours 59 minutes and 59 seconds (pulse width). This is the period of time for which the output will remain on.

The timer output may be set to generate the timed pulse only once (ONESHOT) or continuously (CONT). Select Start (START) to begin outputting the constant timed pulse. Select Stop (STOP) to end outputting the constant timed pulse. Function keys or the digital input may be assigned to start and stop timer functions (see the USER menu

Solid State Relay Outputs (RELAY)

The meter is optionally equipped with two solid state relays that may be set up for alarms, sample, timer, or batch control. Alternatively, they may be disabled. Alarms are available based on the rate, total, or grand total value, or the digital input. The alarm status will show on the display even if the output is not wired. Sample will engage the relay for a programmed period of time when either the total or the grand total have reach a programmed amount. A timer output turns the relay on and off at a specified frequency to act as a timer. For use in batch control applications, the meter relays may be set to batch. This will enable the batch control features of the meter. The output may be disabled by selecting DISABLE.

Caution!

During setup, the relays do not follow the input and they will remain in the state found prior to entering the Relay menu.

Batch Control (BATCH)

Selecting batch control for relay 1 will enable batching features on the meter. The top display will be changed to show the total and the bottom display will be changed to display the preset batch amount. The function keys will be changed so that F1 starts a batch, F2 opens the preset menu to allow the preset value to be changes, and F3 stops the currently running batch. Enabling batch control for relay 1 will allow access to the BATCH menu under relay 2 (this menu does not appear by default).

Batch Control Relay 1

The batch total can be set to count UP or DOWN. The batch MAXIMUM is the max preset amount that can be batched. Batching can be set to either manual or automatic operation (MANUAL or AUTO). If setting batching to automatic, a delay before the next batch is started must be programmed. The PRESET amount is the value at which the batch will stop and can be programmed up to the value assigned in the MAXIMUM menu. An on and off delay may be set for batching relays.

Batch Control Relay 2

The BATCH option only appears under relay 2 if relay 1 has also been set to batch control. The second relay may be programmed as a preclose relay or as another batching relay with its own preset amount.

Relay Information (INFO)

The relay information menu shows run times and cycle counts for each relay. These values may be cleared at any time by selecting the Clear option (CLEAR?).

4-20 mA Output (4-20 mA)

The 4-20 mA menu is used to scale the 4-20 mA output based on display values. This menu is not present on models without a 4-20 mA output option.

The 4-20 mA analog output (if equipped) can be scaled to provide a 4-20 mA signal for the rate or total display range or to simply retransmit the 4-20 mA input. The output may be disabled (DISABLE), and will only output the minimum signal.

Overrange and underrange values determine what mA signal the meter will output if the mA input is underrange (<3.5 mA) or overrange (>20.5 mA). This value may be set to 1-mA, 3.5-mA, 3.8-mA, 20.5mA, 20.8-mA, 23-mA, or disabled.

No equipment is needed to scale the analog output; simply program two display values and corresponding mA output signals.

Rate or Total (RATE or TOTAL)

To scale the analog output, enter display value 1 and a corresponding analog output value for this display, then enter display value 2 and a corresponding analog output value for this display value. This will provide a linearly scaled analog output.

Retransmit (RETRANS)

This option will retransmit the 4-20 mA analog input without the need to scale the output.

Output Control (CONTROL)

The Control menu is used to control the open collector outputs, 4-20 mA analog output, or the relays manually, ignoring the input. Each open collector, relay, and analog output can be programmed independently for manual control. Selecting automatic control sets all relays and analog output for automatic operation.

Signal Input Conditioning Functions (FUNCTION)

The Function menu is used to select the signal input conditioner applied to the input: linear, square root, or programmable exponent calculation. Multi-point linearization is part of the linear function selection. Meters are set up at the factory for linear function with 2-point linearization. The linear function provides a display that is linear with respect to the input signal.

Square Root Linearization (SQROOT)

The square root function can be used to linearize the signal from a differential pressure transmitter and display flow rate in engineering units.

Programmable Exponent Linearization (EXPONENT)

The programmable exponent can be used to linearize the signal from level transmitters in open-channel flow applications using weirs and flumes.

Multi-Point Linearization (LINEAR)

Meters are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be selected for the scaled value under the linear function. Multi-point linearization can be used to linearize the display for non-linear signals to convert level to flow using weirs and flumes with complex exponent.

Advanced Total and Grand Total Programming (ADV TOTAL & ADV GTOTAL)

The advanced total and grand total menu contain the count (COUNT) and reset (RESET) menus. The count menu allows the digit limit to be selected between 8-digit (bottom line only) and 13-digit (uses top and bottom line to display full number) and an initial value at which the total or grand total should begin counting to be set. When using a 13-digit total or grand total, press the function key assigned to display (default: F1) to view the full amount once the value has exceeded 100,000,000 (decimal places are automatically truncated). If a 13-digit total or grand total is displayed on the bottom line and the value has exceeded nine digits, the truncated value will flash to indicate that it is not the complete value. The reset menu allows the resetting of total or grand total to zero to be enabled or disabled. Grand total reset may be permanently disabled by selecting YES at the PERMLOCK menu after disabling grand total reset. Use caution when selecting the PERMLOCK feature as once grand total reset has been permanently locked it cannot be unlocked.

Advanced Scaling and Calibration (SCALE.CAL)

This menu offers options to scale or calibrate the meter.

Scaling the Input (SCALE)

The scale menu in the Advanced menu is the same as the scale menu in the Input menu. See Setting Up the Input Signal (INPUT) on page 17 for details about scaling the meter.

Page 33

Loop Leader PD6622/4 Loop-Powered Rate/Totalizer Instruction Manual

Calibrating the Input (CAL)

To scale the meter without a signal source, refer to Setting Up the Input Signal (INPUT), page 17.

The meter can be calibrated to display the process in engineering units by applying the appropriate input signal and following the calibration procedure. The CAL menu should be used with a live signal coming from a 4-20 mA transmitter connected to the process being measured.

During calibration, the mA input value will be displayed as INP 1 and INP 2. Adjust the input source until the desired mA value is shown. The use of a calibrated signal source is strongly recommended.

1. After accessing the SCALE.CAL menu, press the Right-Arrow button to scroll to the Calibration menu (CAL PV) and press Enter.

2. Select the appropriate units for the desired process variable, then press Enter. For information on units, see Available Unit Classes and Units on page 18.

3. The meter displays INP 1. Apply a known signal and press Enter. The display will flash while accepting the signal.

4. After the signal is accepted, the meter displays DSP 1. Enter a corresponding display value for the signal input, and press Enter to accept.

5. The meter displays INP 2. Apply a known signal and press Enter. The display will flash while accepting the signal.

6. After the signal is accepted, the meter displays DSP 2. Enter a corresponding display value for the signal input and press Enter to accept.

7. After completing calibration, the SAVE? display will need to be acknowledged using the Enter key before calibration will take effect.

Low-Flow Cutoff (CUTOFF)

The low-flow cutoff feature allows the meter to be programmed so that the output from a flowmeter always displays zero on the meter at low flow rates. The cutoff value may be programmed from 0 to 999999.9. The meter will display zero below the cutoff value. Programming the cutoff value to zero disables the cutoff feature.

Noise Filter (FILTER)

The noise filter is available for unusually noisy signals that cause an unstable process variable display. The noise filter averages the input signal over a certain period. The filter level determines the length of time over which the signal is averaged. The filter level can be set between 1 and 16 seconds, or turned off. The higher the filter level, the longer the averaging time and so the longer it takes the display to settle to its final value. Setting the filter level to zero disables the filter function.

Noise Filter Bypass (BYPAS)

The noise filter bypass changes the behavior of the meter so that small variations in the signal are filtered out but large abrupt changes in the input signal are displayed immediately. The bypass value determines the minimum amount of signal change to be displayed immediately. All signal changes smaller than the bypass value are filtered or averaged by the meter. The noise filter bypass may be set between 0.0 and

99.9% of full scale.

Enabling Password Protection (PASSWRD)

The Password menu is used for programming security to prevent unauthorized changes to the programmed parameter settings. There are three password types available: Main, Total, and Grand Total. The Main password prevents access to the meter Programming Mode. Total and Grand Total passwords prevent resetting of and changes to the total and grand total, respectively. In order to set a password, enter the Password menu and program a five-digit password. When the Main password has been enabled, the lock icon will display in the lower right of the display. For instructions on how to program numeric values see Setting Numeric Values, page 16.

Making Changes to a Password Protected Meter

If the Main password is enabled, the meter will display the message LOCKED when the Menu button is pressed. If the Total or Grand Total passwords are enabled, the meter will display the message LOCKED when trying to reset or change the total or grand total. Press the Enter button while the message is being displayed and enter the correct password to gain access to the menu. After exiting Programming Mode, the meter returns to its password protected condition.

Disabling Password Protection

To disable the Main, Total, or Grand Total passwords, access the Password menu and clear the desired password either by pressing and holding the Right Arrow button until all digits reset to zero or manually changing all of the digits to zero. When the Enter button is pressed, the meter will display UNLOCKED and will no longer require a password to access Programming Mode, or a password to reset or change the total or grand total, depending on which password was cleared.

Note: If the meter is password protected and the password has been forgotten, the password may be overridden using the master password: 50865

Enabling the Function Key Hint Feature (HINT)

Enabling the function key hint feature will cause a hint message to be displayed when pressing the F1, F2, or F3 function keys. This text gives a brief description of what the button is programmed to do. Pressing that function key a second time will execute that action. The hint feature does not affect the digital input (DI) which is intended for immediate execution.

Changing System Settings (SYSTEM)

The System menu contains the following menus: Analog Output Calibration, Restore Factory Defaults, Totalizer, Backlight, Information, and Internal Calibration.

Analog Output Calibration (AOUTCAL)

To perform the analog output calibration, it is recommended to use a milliamp meter with a resolution of at least 0.1 µA to measure the output current. The values saved internally during this procedure are used for scaling the 4-20 mA output in the Setup menu.

Resetting the Meter to Factory Defaults (DEFAULT)

When the parameters have been changed in a way that is difficult to determine what’s happening, it might be better to start the setup process from the factory defaults. To load factory defaults, enter the DEFAULT menu under the SYSTEM menu and press enter twice in quick succession. The meter will load the default settings and restart.

Disabling the Totalizer (TOTAL)

The totalizer can be disabled using the TOTAL menu. With the totalizer disabled, the meter will behave as a PD6602 or PD6604 process meter. Refer to the PD6602/4 instruction manual for instructions about programming a PD6602 or PD6604 process meter.

Enabling or Disabling the Backlight (BACKLITE)

The backlight may be enabled or disabled using the Backlight menu. The backlight is enabled by default, but the input must be wired appropriately in order for the backlight to function. See Current Loop (4-20 mA) Connections on page 9. The voltage drop is the same if the backlight is not wired or if it is disabled in the software.

Calibrating the Internal mA Reference (ICAL)

The meter is factory calibrated prior to shipment to display 0 to 100, which corresponds to the 4-20 mA input. The calibration equipment is certified to NIST standards.

The use of calibrated signal sources is necessary to calibrate the internal source of the meter. The meter’s internal source is what allows the user to scale the meter without applying a signal. Check calibration of the meter at least every 12 months. Note: Allow the meter to warm up for at least 15 minutes before performing the internal source calibration procedure. The Internal Calibration menu is part of the Advanced menu. Internal Calibration is performed as follows:

1. Press the Menu button to enter Programming Mode.

2. Press the Right Arrow button twice and press Enter to access the Advanced menu.

3. Press the Up-Arrow button and press Enter to access the System menu.

4. Press the Up-Arrow button and press Enter to access the ICAL menu.

5. The meter displays low input current message (4.000 mA). Apply a 4-mA signal and press Enter. The display flashes for a moment while the meter is accepting the low input signal.

6. After the display stops flashing, the display moves to the high input calibration (20.000 mA). Apply the high input signal and press Enter. The display will flash again while the meter is accepting the high input signal.

Function Keys Operation

During operation, the programmable function keys operate according to the way they have been programmed in the Advanced Features – User menu. The table above shows the factory default settings for F1, F2, and F3.

A hint message may be enabled in order to provide a description of what each function key does prior to executing their assigned function. See Enabling the Function Key Hint Feature (HINT) on page 36.

Digital Input Operation

A digital input is standard on the meter. This digital input is programmed identically to function keys F1, F2, and F3. The input is triggered with a contact closure between DI+ and DI-, or with an active low signal. During operation, the digital input operates according to the way it has been programmed in the Ad- vanced Features – User menu.

Maximum/Minimum Readings

The max & min readings (peak & valley) reached by the rate variable can be displayed either continuously or momentary:

1. Display briefly by pressing the F1 key (default) or assigning to any of the other function keys or to the digital input in the User menu.

2. Display continuously by pressing the Enter button while the max/min is being displayed to lock the display. Press Enter again to unlock.

Any of the F1-F3 function keys (buttons) and the digital input can be programmed to reset the max & min readings. The meters are set at the factory to display the max reading by pressing the Right Arrow/F1 button and to use the Up-Arrow/F2 button to access the Reset menu. Press the Right Arrow button to cycle through the available parameters to reset.

Changing Engineering Units

It is possible to change the display units without the need to re-scale the meter. The UNITS menu within the DISPLAY menu allows the unit of measure to be changed (e.g. from gallons/second (GAL/s) to liters/second (L/s)) and the meter will automatically convert the display values to the new unit of measure. If entering a custom unit (CUSTM), a custom conversion factor will need to be entered. See Changing the Units (UNITS) on page 19.

Troubleshooting Tips

Symptom

Check/Action

No display at all

1. Check that the 4-20 mA current loop is providing at least 3.5 mA to the meter.

2. Check that the voltage drop of all devices connected to the 4-20 mA current loop does not exceed the max rating of the loop power supply.

Not able to change setup or programming, LOCKED is displayed

Meter is password-protected, enter correct five-digit password to unlock.

Meter display flashes:

1. 999999

2. -99999

Check that the number of digits required for the scaled value does not exceed the maximum digits for the display line. If it does, try adjusting the decimal point location for less precision or changing the PV display to the bottom line.

Display is unstable

Check:

1. Input signal stability and value.

2. Display scaling vs. input signal.

3. Filter and bypass values (increase).

Display response is too slow

Check filter and bypass values

Display reading is not accurate

Check:

1. Signal input conditioner selected: Linear, square root, etc.

2. Scaling or calibration

Display does not respond to input changes, reading a fixed number

Check display assignment. It might be displaying max, min, or set point.

Display shows MAX, MIN, RATE, TOTAL, or GTOT and a number

Max or min display has been locked. Press Enter to unlock max/min display readings.

Relay operation is reversed

Check fail-safe settings in Output menu

Relays do not respond to signal

Check:

1. Relay action in Output menu

2. Set and reset points

If the display locks up or the meter does not respond at all

Cycle the power to reboot the microprocessor.

Other symptoms not described above

Call Technical Support for assistance.

Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory defaults and map changes ahead of time, rather than at random. See Reset Meter to

Factory Defaults on page 39 for details on resetting the meter.
