FREE MeterView Pro Programming Software
The meter can be powered from the USB connection. When using the USB connection, DO NOT apply AC or DC power to the meter.
The easiest and quickest way to program your Helios meter is to use the FREE MeterView Pro programming software. This software is loaded into the meter and connects and installs directly to your PC with a USB cable. We recommend that the first thing you do after taking the meter out of the box is connect the Helios to your PC with the provided USB cable – do not use a different cable. DO NOT apply AC or DC power to the meter while your PC is connected to the meter as
it will disrupt the USB connection. You don’t even
have to apply an input signal. MeterView Pro programming software is intuitive, and
most customers can get their meter programmed as they like without even looking in the manual.
Watch MeterView Pro Software Video at
www.predig.com/meterviewpro
In addition to programming, the software may be used for:
• Monitoring
• Datalogging using your PC
• Generating and saving programming files for
later use
Once your meter is programmed the way you want it, you can wire it up for your application per the instructions in this manual and install it. If you find that you need to make adjustments to the programming after the meter is installed, you can use the programming buttons and the instructions in this manual to do so.

Introduction

The Helios PD2-6000 is a multi-purpose, easy to use, large-display digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. It features large 1.8 inch superluminous LED digits, which can be read in direct sunlight from up to 100 feet (30 meters) away. It is housed in a water-resistant, field-mountable NEMA 4X/IP65 rated enclosure for convenient indoor and outdoor installation.
The programming buttons are located behind the lower panel door and are not generally accessible during operation. For that reason, we recommend the use of the PDA2364-MRUE remote control station which has four buttons to mimic the buttons behind the panel.
The meter accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the programming buttons can be set for custom operation. The analog input can be scaled to display the process in two different scales; for example, the main display could indicate level in feet and the second display could indicate the volume in gallons.
A fully loaded Helios PD2-6000 meter comes with four SPDT relays, a 4-20 mA output, two 24 VDC power supplies, five digital inputs and four digital outputs, and RS-485 serial communications.
The four relays can be used for alarm indication or process control applications such as pump alternation control. The 4-20 mA isolated output, Modbus RTU serial communications, and digital I/O features make the Helios an excellent addition to any system.

Switching Inductive Loads

The use of snubbers to suppress electrical noise is strongly recommended when switching inductive
loads to prevent disrupting the microprocessor’s
operation. The snubbers also prolong the life of the relay contacts. Suppression can be obtained with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the following circuits for RC network assembly and installation:
Figure 16. AC and DC Loads Protection
Choose R and C as follows: R: 0.5 to 1 Ω for each volt across the contacts C: 0.5 to 1 µF for each amp through closed
contacts
Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.
3. Install the RC network at the meter's relay screw terminals. An RC network may also be installed across the load. Experiment for best results.
Use a diode with a reverse breakdown voltage two to three times the circuit voltage and forward current at least as large as the load current.
Figure 17. Low Voltage DC Loads Protection
RC Networks (Snubbers) Available from Precision Digital
RC networks are available from Precision Digital and should be applied to each relay contact switching an inductive load. Part number: PDX6901.
Note: Relays are de-rated to 1/14th HP (50 watts) with an inductive load.

RS-485 Connections

The RS-485 connections are made to a five terminal connector used for Modbus® RTU serial communications. The RS-485 terminals include Transmit Data (DO) and (/DO), Receive Data (DI) and (/DI), and Signal Ground. See Modbus RTU Serial Communications (serial) on page 42 for more information.
There are three diagnostic LEDs: Power (PWR) Transmit Data (TX), and Receive Data (RX) to show when the meter is transmitting and receiving data from other devices.
Figure 18. RS-485 Connection

RS-485 Multi-Drop Connection

When using more than one meter in a multi-drop mode, each meter must be provided with its own unique address. The meter address (Slave ID) can be programmed between 1 and 247. The transmit delay can be set between 0 and 199 ms. The parity can be set to even, odd, or none with 1 or 2 stop bits.

Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as interlock relay(s). Interlock contact(s) are wired to digital input(s) and activate the interlock relay. This feature is enabled by configuring the relay, and the corresponding digital input(s), see Setting Up the Interlock Relay (Force On) Feature on page 38.
In the example below, an Interlock Contact switch is connected to a digital input, which will be used to force on (energize) the Interlock Relay. The Interlock Relay and the Control Relay are connected in series with the load.
• When the Interlock Contact is closed (safe), the Interlock Relay energizes, allowing power to flow to the Control Relay; the corresponding front panel LED is on.
• When the Interlock Contact is open, the corresponding front panel LED flashes (locked out), the Interlock Relay is de-energized, preventing power from flowing to the Control Relay and the load.

Programming the Meter (prog)

The meter may either be scaled (SCALE) without applying an input or calibrated (Cal) by applying an input. The meter comes factory calibrated to NIST standards, so for initial setup, it is recommended to use the (SCALE) function.
The Program menu contains the Scale (SCALE) and the Calibrate (Cal) menus.
Process inputs may be scaled or calibrated to any display within the range of the meter.
The PD2-6000 is a single input meter with dual-scale capability.
If the dual-scale level feature is selected in the Setup menu, the Scale 1 and Scale 2 menus are enabled for PV1 & PV2 respectively.
The process input may be calibrated or scaled to any display value within the range of the meter.
Note: The Scale and Calibrate functions are exclusive of each other. The meter uses the last function programmed. Only one of these methods can be employed at a time. The Scale and Calibrate functions can use up to 32 points (default is 2). The number of points should be set in the Advanced menu prior to scaling and calibration of the meter. See Multi-Point Linearization (Linear) menu on page 43 for details.
Program Menu for Single Scale Process
Program Menu for Dual-Scale Level Applications
Additional parameters, not needed for most applications, are programmed in the Advanced Features menu. See Advanced Features Menu on page 41.
Multi-Point Calibration & Scaling
The meter is set up at the factory for 2-point linear calibration. The number of points for multi-point calibration/scaling is set up in the Advanced Features menu. Up to 32 linearization points may be selected for PV1 and up to 8 linearization points may be selected for PV2. See Multi-Point Linearization (Linear) menu on page 43 for details.
Scaling the Meter (SCALE)
The process input (4-20 mA, 10 VDC) can be scaled to display the process variable in engineering units.
A signal source is not needed to scale the meter; simply program the inputs and corresponding display values.
Dual-Scale for Level Applications
The analog input can be displayed in two different scales, by enabling the dual-scale feature (d-SCAL) in the Setup - Input menu. See Setting the Input Signal (Input) on page 26.
To enable the dual-scale feature for some level applications you must select d-SCAL in the Input selection menu.

Error Message (Error)
An error message indicates that the calibration or scaling process was not successful.
After the error message is displayed, the meter reverts to the input prior to the failure during calibration or scaling and to input 1 during internal calibration, allowing the appropriate input signal to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards*.
2. Wrong signal selection in Setup menu*.
3. Minimum input span requirements not maintained.
4. Input 1 signal inadvertently applied to calibrate input 2*.
*Not relevant when scaling the meter.
For instructions on how to program numeric values see Setting Numeric Values, page 26.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2 signals required to complete the calibration or scaling of the meter.
Input Range
Input 1 & Input 2 Span
4-20 mA
0.15 mA
10 VDC
0.10 VDC
Calibrating the Meter with External Source (Cal)
Note: To scale the meter without a signal source refer to Scaling the Meter (SCALE) on page 28.
The meter can be calibrated to display the process variable in engineering units by applying the appropriate input signal and following the calibration procedure. The use of a calibrated signal source is strongly recommended to calibrate the meter.
Note: Inputs for the above example are: Input 1: 4.00 mA; Display 1: 0.0 Gallons Input 2: 20.00 mA; Display 2: 15000.0 Gallons
Warm up the meter for at least 15 minutes before
performing calibration to ensure specified
accuracy.

The meter has eight display intensity levels to give the best performance under various lighting conditions. Select intensity 8 for outdoor applications. The default intensity is 6.
Display Toggling Between Reading & Units with Tag
The PD2-6000 can be programmed so that line 1 toggles between the reading and units and line 2 displays a tag. For instance, line 1 toggles between 9500 and Gal and line 2 displays Tank 1.
Display Parameter Menu
Dual-Scale Display Feature
The dual-scale feature is of particular value in level applications where a second scaled display can represent the measured input in a different form (i.e. gallons & height). Both displays are independently scaled and are based on the 4-20 mA input signal.

Setting the Relay Action

Operation of the relays is programmed in the Action menu. The relays may be set up for any of the following modes of operation:
1. Automatic reset (non-latching)
2. Automatic + manual reset at any time (non­latching)
3. Latching (manual reset only, at any time)
4. Latching with Clear (manual reset only after alarm condition has cleared)
5. Pump alternation control (automatic reset only)
6. Sampling (the relay is activated for a user­specified time)

Programming Set and Reset Points

High alarm indication: program set point above reset point.
Low alarm indication: program set point below reset point.
The deadband is determined by the difference between set and reset points. Minimum deadband is one display count. If the set and reset points are programmed with the same value, the relay will reset one count below the set point.
Note: Changes are not saved until the reset point has been accepted.

Setting Fail-Safe Operation

In fail-safe mode of operation, the relay coil is energized when the process variable is within safe limits and the relay coil is de-energized when the alarm condition exists. The fail-safe operation is set independently for each relay. Select on to enable or select off to disable fail-safe operation.

Programming Time Delay

The On and Off time delays may be programmed for each relay between 0 and 999.9 seconds. The relays will transfer only after the condition has been maintained for the corresponding time delay.
The On time delay is associated with the set point. The Off time delay is associated with the reset point.

Relay Action for Loss of 4-20 mA Input (Loop Break)

A loop break condition is triggered when the 4-20 mA input signal drops below 0.005 mA. Each relay may be programmed to go to one of the following conditions when the meter detects the loss of the input signal (i.e. < 0.005 mA):
1. Turn On (Go to alarm condition)
2. Turn Off (Go to non-alarm condition)
3. Ignore (Processed as a low signal condition)
The following graph shows the loop break relay operation for a high alarm relay.

Relay and Alarm Operation Diagrams

The following graphs illustrate the operation of the relays, status LEDs, and ACK button.

High Alarm Operation (Set > Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To detect a new alarm condition, the signal must go below the set point, and then go above it.
Page 33
Helios PD2-6000 Analog Input Process Meter
Instruction Manual
33

Low Alarm Operation (Set < Reset)

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. For relay to turn back “on”, signal must go above set point and then go below it.

High Alarm with Fail-Safe Operation (Set > Reset)

Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.

Low Alarm with Fail-Safe Operation (Set < Reset)

Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.

Time Delay Operation

The following graphs show the operation of the time delay function.
When the signal crosses the set point, the On time delay timer starts and the relay trips when the time delay has elapsed. If the signal drops below the set point (high alarm) before the time delay has elapsed, the On time delay timer resets and the relay does not change state. The same principle applies to the Off time delay.
Note: If “Automatic or Manual (A-nmAn)” reset mode is
selected, the LED follows the reset point and not the relay state when the relay is acknowledged.

Pump Alternation Control Operation

Relay Sampling Operation

When the signal crosses the set point, the relay trips and the sample time starts. After the sample time has elapsed, the relay resets. The cycle repeats every time the set point is crossed, going up for high alarms and going down for low alarms.
The sample time can be programmed between 0.1 and 5999.9 seconds.

Relay Operation Details

Overview

The four-relays option for the meter expands its usefulness beyond simple indication to provide users with alarm and control functions. Typical applications include high and low temperature, level, pressure or flow alarms, control applications such as simple on/off pump control, and pump alternation control for up to 4 pumps. There are four basic ways the relays can be used:
1. High and Low Alarms with Latching or Non­Latching Relays
2. Simple On/Off Control with 100% Adjustable Deadband
3. Sampling (Based on Time)
4. Pump Alternation Control for up to 4 Pumps

Relays Auto Initialization

When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter. The following table indicates how the alarm LEDs and relays will react on power-up based on the set and reset points:

Fail-Safe Operation

The following table indicates how the relays behave based on the fail-safe selection for each relay:

Note: NO = Normally Open, NC = Normally Closed.
This refers to the condition of the relay contacts when the power to the meter is off.

Front Panel LEDs

The alarm status LEDs on the front panel are available on all meters, even those without relays installed, and provide status indication for the following:
LED
Status
1
Alarm 1
2
Alarm 2
3
Alarm 3
4
Alarm 4
The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication. The LEDs are controlled by the set and reset points programmed by the user. When the display reaches a set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to the reset point the LED will go off. The front panel LEDs respond differently for latching and non-latching relays.
For non-latching relays, the LED is always off during normal condition and always on during alarm condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).
For latching relays, the alarm LEDs reflect the status of the relays, regardless of the alarm condition. The following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge button (Default: F3 key assigned to ACK).

Latching and Non-Latching Relay Operation

The relays can be set up for latching (manual reset) or non-latching (automatic reset) operation.

Non-Latching Relay (Auto)

In this application, the meter is set up for automatic reset (non-latching relay). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm finally goes away, the relay automatically resets and the LED also goes off.

Non-Latching Relay with Manual Reset (A-nman)

In this application, the meter is set up for automatic and manual reset at any time (non-latching relay). The LED and the relay automatically reset when the meter returns to the normal condition.
In addition, the relay can be manually reset while the alarm condition still exists, but the LED will stay on until the meter returns to the normal condition.

Latching Relay with Clear (Lt-Clr)

In this application, the meter is set up for manual reset only after the signal passes the reset point (alarm condition has cleared). Acknowledging the alarm while it is still present has no effect on either the LED or the relay. When the alarm is acknowledged after it returns to the normal state, the LED and the relay go off. Notice that the LED remains on, even after the meter returns to the normal condition. This is because, for latching relays, the alarm LED reflects the status of the relay, regardless of the alarm condition.

Acknowledging Relays

There are three ways to acknowledge relays programmed for manual reset:
1. Via the programmable front panel function keys F1-F3 (Example: F3 assigned to ACK).
2. Remotely via a normally open push button wired to the F4 terminal.
3. Remotely via a normally open push button wired to one of the digital inputs and the +5 V terminal on the digital I/O connections.
When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.
Acknowledging Relays with Remote Control Station
Relays may be remotely acknowledged by connecting the PDA2361-A to either the F4 terminal or a digital input as described above.

Pump Alternation Control Applications (Altern)

For pump control applications where two or more similar pumps are used to control the level of a tank or a well, it is desirable to have all the pumps operate alternately. This prevents excessive wear and overheating of one pump over the lack of use of the other pumps. Up to 4 relays can be set up to alternate every time an on/off pump cycle is completed. The set points and reset points can be programmed, so that the first pump on is the first pump off.
Application #1: Pump Alternation Using Relays 1 & 2
1. Relays 1 and 2 are set up for pump alternation.
2. Relays 3 and 4 are set up for low and high alarm indication.

Pump Alternation Operation
1. Pump #1 turns on when level reaches 30.000, when level drops below 10.000, pump #1 turns off.
2. The next time level reaches 30.000, pump #2 turns on, when level drops below 10.000, pump #2 turns off.
3. If the level doesn’t reach 35.000, pump #1 and pump #2 will be operating alternately.
4. If pump #1 cannot keep the level below 35.000, pump #2 will turn on at 35.000, then as the level drops to10.000, pump #1 turns off, pump #2 is still running and shuts off below 5.000.
5. Notice that with the set and reset points of pump #2 outside the range of pump #1, the first pump on is the first pump to go off. This is true for up to 4 alternating pumps, if setup accordingly.
6. Relay #3 will go into alarm if the level drops below 4.000 and relay #4 will go into alarm if the level exceeds 40.000.
Application #2: Pump Alternation Using Relays 3 & 4
1. Relays 1 and 2 are set up for low and high alarm indication.

Pump Alternation Visual Representation
The following graphics provide a visual representation of a typical pump alternation application with high and low alarm monitoring:
1. Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.
2. With the Pump Alternation feature activated, the next time the level reaches 6000 gallons, relay #3 transfers and starts the backup pump.
3. If the backup pump is not able to keep up, and the level reaches 7000 gallons, relay #4 transfers and starts the main pump as well.
4. Relay #2 trips the High Level Alarm at 7500 gallons and resets at 6900 gallons.
5. Relay #1 trips the Low Level Alarm at 495 gallons and resets at 750 gallons.

Setting Up the Interlock Relay (Force On) Feature

Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:
1. Access the Setup – Relay – Action menu and set the action to off.
2. In the Advanced features – User menu program
any of the digital inputs to Force On any of the internal relays (1-4).
3. Connect a switch or dry contact between the +5V
terminal and the corresponding digital input (dI-1 to dI-4) terminal.
Interlock Relay Operation Example
Relays 1 & 2 are configured to energize (their front panel LEDs are steady on) when SW1 & SW2 switches (above) are closed. If the contacts to these digital inputs are opened, the corresponding front panel LEDs flash indicating this condition. The processes being controlled by the interlock relay will stop, and will re-start only after the interlock relay is re-activated by the digital inputs (switches).
Note: If multiple digital inputs are assigned to the same relay, then the corresponding logic is (AND) – i.e. both switches must be closed to activate the relay.
• If the digital inputs are assigned to the Interlock
Function, then they cannot be used to program
the meter remotely.

Scaling the 4-20 mA Analog Output (Aout)

The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any display range selected.
No equipment is needed to scale the analog output; simply program the display values to the corresponding mA output signal.
The Analog Output menu is used to program the 4-20 mA output based on display values.
For further details, see Setting Numeric Values
on page 26, Analog Output Value for Loss of
4-20 mA Input (Loop Break) on page 44.

Reset Menu (reset)

The Reset menu is used to reset the maximum or minimum reading (peak or valley) reached by the process; both may be reset at the same time by selecting “reset high & low” (rst HL). The tare value used to zero the display may be reset by selecting “reset tare” (rst tr).

Setting Up the Password (pass)

The Password menu is used for programming three levels of security to prevent unauthorized changes to the programmed parameter settings.
Pass 1: Allows use of function keys and digital inputs Pass 2: Allows use of function keys, digital inputs and editing set/reset points Pass 3: Restricts all programming, function keys, and digital inputs.

Protecting or Locking the Meter

Enter the Password menu and program a six-digit password. For instructions on how to program numeric values see Setting Numeric Values on page 26.

Making Changes to a Password Protected Meter

If the meter is password protected, the meter will display the message Locd (Locked) when the Menu button is pressed. Press the Enter button while the message is being displayed and enter the correct password to gain access to the menu. After exiting the programming mode, the meter returns to its password protected condition.

Disabling Password Protection

To disable the password protection, access the Password menu and enter the correct password twice, as shown below. The meter is now unprotected until a new password is entered.
If the correct six-digit password is entered, the meter displays the message unLoc (unlocked) and the protection is disabled until a new password is programmed. If the password entered is incorrect, the meter displays the message Locd (Locked) for about two seconds, and then it returns to Run Mode. To try again, press Enter while the Locked message is displayed.
Did you forget the password?
The password may be disabled by entering a master password once. If you are authorized to make changes, enter the master password 508655 to unlock the meter.

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 2 and 199. 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 (bypass)

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 0.1 and
99.9% of full scale.

Rounding Feature (round)

The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used in addition to the filter function.
Rounding causes the display to round to the nearest value according to the rounding selected. See examples below:

Modbus RTU Serial Communications (serial)

The meter is equipped with serial communications capability as a standard feature using Modbus RTU Serial Communication Protocol. The meter may be connected to a PC for initial configuration via the on-board USB connection. For ongoing digital communications with a computer or other data terminal equipment, use the RS-485 connection with the appropriate serial converter; see Ordering Information on page 6 for details.
• DO NOT connect any equipment to the RJ45
M-LINK connector. Otherwise damage will occur to the equipment and the meter.
• DO NOT disconnect the RJ45 connector located
to the left of the power terminal block. Doing so will disable the on-board digital I/O, and the RS-485 serial communications.
Notes:
1. More detailed instructions are provided with each
optional serial communications adapter.
2. Refer to the Helios Modbus Register Tables
located at www.predig.com for details.
When using more than one meter in a multi-drop mode, each meter must be provided with its own unique address. The meter address (Slave ID) may be programmed between 1 and 247. The transmit delay may be set between 0 and 199 ms. The parity can be set to even, odd, or none with 1 or 2 stop bits.

Select Menu (SElect)

The Select menu is used to select the input signal conditioner applied to the input (linear, square root, programmable exponent, or round horizontal tank), low-flow cutoff, and analog output programming. The multi-point linearization is part of the linear function selection.

Input Signal Conditioning (Functn)

The Function menu is used to select the input signal conditioner applied to the input: linear, square root, programmable exponent, or round horizontal tank volume calculation. The 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 (Square)
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 (Prog E)
The programmable exponent can be used to linearize the signal from level transmitters in open-channel flow applications using weirs and flumes. For more information on how the Programmable Exponent Linearization feature works, see the PD6200 manual.
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 PV1 under the linear function. The multi-point linearization can be used to linearize the display for non-linear signals such as those from level transmitters used to measure volume in odd-shaped tanks or to convert level to flow using weirs and flumes with complex exponent. If the dual-scale level feature has been selected, the menus for PV1 & PV2 are enabled. PV2 can be programmed with up to 8 linearization points.
Round Horizontal Tank Linearization (rHt)
This function automatically calculates the volume in a round horizontal tank with flat ends.
Set the display for the desired decimal point and engineering units before entering the round horizontal tank function. Select units, inches or cm for the tank dimensions. Enter the diameter and the length in inches and the results are calculated automatically in US gallons. Enter the diameter and length in cm and the results are calculated automatically in liters. The meter can be scaled to display the volume in any engineering unit.
Note: After Scale is displayed continue pressing the Enter button until the meter completes the scaling of the input and display values.

Changing the Volume from Gallons to Liters
In the above graphic, entering 48" for the diameter and 120" for the length of the round horizontal tank, the meter automatically calculates that the volume of the tank is 940.02 gallons.
1. Convert gallons to liters 1 US gallon = 3.7854 L
940.02 gal = 3558.4 L
2. Go to the Setup menu and change the decimal point to 1 decimal.
3. Go to the Program – Scale menu and press Enter until dis 2 is shown on the main display.
4. Press Enter and change the display 2 value to
3558.4.
5. The meter is now displaying the volume in liters.
Note: The display can be scaled to display the volume
in any engineering units.
Another way to display the volume in liters is to enter the dimensions in cm. The meter automatically calculates the volume in liters.

Low-Flow Cutoff (CutofF)

The low-flow cutoff feature allows the meter to be programmed so that the often-unsteady output from a differential pressure transmitter, at low flow rates, always displays zero on the meter. The cutoff value may be programmed from 0.1 to
999999. The meter will display zero below the cutoff value. Programming the cutoff value to zero disables the cutoff feature. The cutoff can be disabled to display negative values.

Analog Output Programming (AoutPr)

The Analog Output Programming menu is used to program the behavior of the 4-20 mA output. The following parameters and functions are programmed in this menu:
1. Source: Source for generating the 4-20 mA output (e.g. PV)
2. Overrange: Analog output value with display in overrange condition
3. Underrange: Analog output value with display in underrange condition
4. Break: Analog output value when loop break is detected
5. Max: Maximum analog output value allowed regardless of input
6. Min: Minimum analog output value allowed regardless of input
7. Calibrate: Calibrate the internal 4-20 mA source reference used to scale the 4-20 mA output
Analog Output Source
The source for generating the 4-20 mA output may be assigned to the process variable, maximum or minimum value reached by the process, one of the set points, or the Modbus PV input.
Analog Output Value for Loss of 4-20 mA Input (Loop Break)
The AoutPr - Break menu is used to force the analog output to go to a user-specified mA value if a break condition is detected in the 4-20 mA input loop. Selecting Ignore causes the mA output to go to the minimum value.
Analog Output Calibration
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.
Analog Output Calibration Procedure
1. Wire the PD2-6000 4-20 mA output to a current loop that includes a power supply (internal or external 12 to 24 VDC), and the mA input on the digital meter. See Figure 25. 4-20 mA Output Connections on page 21 for details.
2. Turn on all devices. Allow for a 15 to 30 minute warm-up.
3. Go to the Advanced Features menu, and navigate to the Analog Output Programming (AoutPr) Calibration (Calib) menu and press Enter.
4. The display will show 4 nmA. The PD2-6000 mA output should now be close to 4 mA. Press Enter and the display will show 04.000. Enter the actual value read by the digital mA meter and press Enter.
5. The display will show 20 nmA. The PD2-6000 mA output should now be close to 20 mA. Press Enter and the display will show 20.000. Enter the actual value read by the digital mA meter and press Enter.
6. The meter will now calculate the calibration factors and store them.
7. Press Menu to exit and return to Run mode.

Programmable Function Keys User Menu (user)

The User menu allows the user to assign the front programming buttons function keys F1, F2, and F3, the digital input F4 (located on the input signal connector), and four digital inputs (located on the digital I/O connector) to access most of the menus or to activate certain functions immediately (e.g. reset max & min, hold relay states, etc.). This allows the meter to be greatly customized for use in specialized applications.
The four digital outputs can be assigned to a number of actions and functions executed by the meter (i.e. alarms, relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital outputs can be used to trigger external alarms or lights to indicate these specific events.

Tare (tare)

The tare function zero’s out the display. In the case of
scale weight, tare is used to eliminate container weight and provide net weight readings. There are two tare functions; Capture Tare and Reset Tare. When the capture tare function is used, the display reading is offset by the displayed amount to make the displayed value zero. This modified display value is the net value. The originally displayed value without the tare offset is the gross value. Both may be chosen as a display option.
Reset tare removes the display offset of the net value, and the gross and net values become the same until a new capture tare is entered.

Internal Source Calibration (ICAL)

The meter is factory calibrated prior to shipment for milliamps and volts with calibration equipment that 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. Each input must be recalibrated separately.
Notes:
1. If meter is in operation and it is intended to accept only one input type (e.g. 4-20 mA), recalibration of other input is not necessary.
2. 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 Features menu.
1. Press and hold the Menu button for three seconds to access the advanced features of the meter.
2. Press the Up arrow button to scroll to the Internal calibration menu (ICAL) and press Enter.
3. The meter displays either current calibration (C CAL) or voltage calibration (V CAL), according to the input setup. Press Enter to start the calibration process.
Example of Internal Calibration for current input:
4. The meter displays low input current message (C lo). Apply the low input signal and press Enter. The display flashes for a moment while the meter is accepting the low input signal.
5. After the display stops flashing, a number is displayed with the leftmost digit brighter than the rest. The bright digit is the active digit that can be changed by pressing the Up arrow button. Press the Right arrow button to move to the next digit.
6. Set the display value to correspond to the input signal being calibrated, typically
4.000 mA.
7. The display moves to the high input calibration (C Hi). Apply the high input signal and press Enter.
8. Set the display for the high input calibration, in the same way as it was set for the low input calibration, typically 20.000 mA.
The following graphic shows the calibration of the current input. The voltage input is calibrated in a similar way.
Tips:
• Low and high input signals can be any valid values within the range of the meter.
• Observe minimum input span requirements between input 1 and input 2.
• Low input should be less than high input signal. However, the low display can be higher than the high display (i.e. 4-20 mA = 100.0 to 0.0).
Error Message (Error)
An error message indicates that the calibration or scaling process was not successful.
After the error message is displayed, the meter reverts to the input prior to the failure during calibration or scaling and to input 1 during internal calibration, allowing the appropriate input signal to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards*.
2. Wrong signal selection in Setup menu*.
3. Minimum input span requirements not maintained.
4. Input 1 signal inadvertently applied to calibrate input 2*.
*Not relevant when scaling the meter.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and input 2 signals required to complete the calibration or scaling of the meter.

Meter Operation

The meter is capable of accepting current (0-20 mA, 4-20 mA) and voltage signals (0-5 V, 1-5 V, 0-10 V, 10 V) and displaying these signals in engineering units from -99999 to 999999 (e.g. a 4-20 mA signal could be displayed as -50.000 to 50.000).
The dual-line display can be customized for the user’s specific application. Typically, the main display is used for the process variable; while the second display is used for engineering units, custom legend, or set point indication.
The analog input can be scaled to display the process in two different scales; for example: with d-SCAL enabled, the main display could indicate level in feet and the second display could indicate the volume in gallons.
Additionally, the meter can be set up to display the analog input on the main display and the Modbus input on the second display. The relays and analog output can be programmed to operate from the Modbus PV input.

Troubleshooting Tips

This meter is a highly sophisticated instrument with an extensive list of features and capabilities. If the programming buttons are used to program the meter, it may be a difficult task to keep everything straight. That is why we strongly recommend the use of the free MeterView Pro software for all programming activities. A USB cable is provided with the meter for programming with MeterView Pro software.
If you have programmed the meter with the programming buttons and it is not working as intended, try re-programming the meter using MeterView Pro software.
Symptom
Check/Action
No display at all
Check power at power connector
Not able to change setup or programming, Locd is displayed
Meter is password-protected, enter correct six-digit password to unlock or Master Password of 508655.
Meter does not respond to input change
If a Low-Flow Cutoff Value has been programmed, the meter will display zero below that point, regardless of the input – which can appear like the meter is not responding to an input change. Check to make sure the problem is not being caused by an undesired low-flow cutoff value. To prevent the display from showing a negative value, set the low­flow cutoff to a value greater than zero.
Meter displays error message during calibration (Error)
Check:
1. Signal connections
2. Input selected in Setup menu
3. Minimum input span requirements
Meter displays
1. 999999
2. -99999
Check:
1. Input selected in Setup menu
2. Corresponding signal at Signal connector
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. Input signal conditioner selected: Linear, square root, etc.
2. Scaling or calibration
Display does not respond to input changes, reading a fixed number
Check:
1. Display assignment, it might be displaying max, min, or set point.
Display alternates between
1. Hi and a number
2. Lo and a number
Press Menu to exit max/min display readings.
Relay operation is reversed
Check:
1. Fail-safe in Setup menu
2. Wiring of relay contacts
Relay and status LED do not respond to signal
Check:
1. Relay action in Setup menu
2. Set and reset points
Flashing relay status LEDs
Relays in manual control mode or relay interlock switches opened.
Meter not communicating with application programs
Check:
1. Serial adapter and cable
2. Serial settings
3. Meter address and baud rate
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 use the manual as a step by step programming guide, rather than a random approach to programming. To reset the meter to factory defaults, see Reset Meter to Factory Defaults on page 48. In addition, for best results, we recommend using the free MeterView Pro software for all programming needs.
