PD6060 is a multipurpose, easy to use digital dual-input process meter ideal for level, flow rate, temperature transmitter, or pressure transmitter applications.

It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Various math functions may be applied to the inputs including addition, difference, absolute difference, average, weighted average, multiplication, division, minimum, maximum, draw, ratio, and concentration. This is in addition to the signal input conditioning functions (linear, square root, programmable exponent, or round horizontal tank calculations).

The displays, relays, and the analog output may be assigned to input channels A or B, or math result channel C.

Three of the front panel buttons can be custom-programmed for a specific operation.

The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitters or other devices. An additional isolated 24 VDC power supply is included with the 4-20 mA output option. A digital input is standard.

A fully loaded PD6060 meter has the following: four SPDT relays, 4-20 mA output, and two 24 VDC power supplies. The PD6060 capabilities may be enhanced by adding the following external expansion modules: four SPST relays –creating an eight-relay dualinput process meter, two digital I/O modules with four inputs and four outputs each, serial communication adapters for use with MeterView Pro or Modbus RTU, and a dual 4-

20 mA expansion module.

Switching Inductive Loads

The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors 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:

C

R

R

Figure 13. 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 14. Low Voltage DC Loads Protection

RC Networks 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.

Warning!


External Relay, Analog Output, & Digital I/O Connections

The relay, analog out, and digital I/O expansion modules PDA1004,

PDA1011, and PDA1044 are connected to the meter using a CAT5 cable provided with each module. The two RJ45 connectors on the expansion modules are identical and interchangeable; they are used to connect additional modules to the system.

Note: The jumper located between the RJ45 connectors of the

PDA1044 must be removed on the second digital I/O module in order for the system to recognize it as module #2.

Do not connect or disconnect the expansion modules with the power on!

More detailed instructions are provided with each optional expansion module.

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 trigger the interlock relay. This feature is enabled by configuring the relay, and relative digital input(s) (see page

61). In one example, dry interlock contacts are connected in series to one digital input which will be used to force on (energize) the assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O contact). See below.

2. Turn (Go to non-alarm condition)

3. Ignore (Processed as a low signal condition)

Note: This is not a true loop break condition; if the signal drops below

0.005 mA, it is interpreted as a “loop break” condition.

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-mAn)” reset mode is selected, the

LED follows the reset point and not the relay state when the relay is acknowledged.

Relay Operation Details

Overview

The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2 or

4 optional internal relays and/or 4 external relays expansion module.

Typical applications include high or low temperature, level, pressure or flow alarms, control applications such as simple on/off pump control, and pump alternation control for up to 8 pumps. There are four basic ways the relays can be used:

1. High or Low Alarms with Latching or Non-Latching Relays

2. Simple On/Off Control with 100% Adjustable Deadband

3. Sampling (Based on Time)

4. Pump Alternation Control for up to 8 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 failsafe selection for each relay:

Fail-Safe

Selection

Non-Alarm State Alarm State Power Failure

Off Open Closed Closed Open Relays to non-alarm state

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 LEDs on the front panel provide status indication for the following:

LED Status

3

Alarm 1

Alarm 2

Alarm 3

LED Status

5

6

7

Alarm 5

Alarm 6

Alarm 7

4 Alarm 4 8 Alarm 8

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 responds 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 reflects 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.

Relay terminology for following tables

Terminology Relay Condition

Ack Acknowledged

The On and Off terminology does not refer to the status of the relay’s coil, which depends on the fail-safe mode selected.

Warning!

In latching relay mode, latched relays will reset (unlatch) when power is cycled.

57


Non-Latching Relay (Auto)

Automatic reset only

Condition LED


Relay

Ack (No effect) On On

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 (A-man)

Automatic + manual reset at any time

Condition LED Relay

Next Alarm

Ack

On

On

On

Off

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.

The next time an alarm occurs, the operator acknowledges the alarm manually while the alarm condition still exists. This causes the relay to reset, but the LED stays on until the meter returns to the normal condition.

Latching Relay (LatcH)

Manual reset any time


In this application, the meter is set up for manual reset at any time.

Acknowledging the alarm even if the alarm condition is still present resets the relay and turns off the LED.

58


Latching Relay (Lt-Clr)

Manual reset only after alarm condition has cleared


Ack (No effect) On On

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 two ways to acknowledge relays programmed for manual reset:

1. Via the programmable front panel function keys F1-F3 (Default:

F3 assigned to ACK).

2. Remotely via a normally open pushbutton wired across one of the digital inputs and the +5 V terminals on the digital I/O modules, or using the F4 digital input, which is triggered with a contact closure to COM, or with an active low signal (see page

24).

When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are acknowledged.

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 8 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 to 10.000 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 8 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.

7. Adding the 4 external relays expansion module allows using the 4

SPDT internal relays for pump alternation and the 4 SPST external relays for high, high-high, low, and low-low alarm indication.

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 off) 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 reactivated 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 trip the relay.

Scaling the 4-20 mA Analog Output (Aout)

The 4-20 mA analog outputs can be scaled to provide a 4-20 mA signal for any display range selected. To select the channel and source assignments the analog outputs are assigned to, see Analog Output

Source

on page 78.

No equipment is needed to scale the analog outputs; simply program the display values to the corresponding mA output signal.

The Analog Output menu is used to program the 4-20 mA outputs based on display values.

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).

Control Menu (Contrl)

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

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.

71


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. This setting affects the last two digits, regardless of decimal point position.

Modbus RTU Serial Communications (serial)

The meter is equipped with serial communications capability as a standard feature using Modbus RTU Serial Communication Protocol.

To communicate with a computer or other data terminal equipment, an

RS-232, RS-485, or USB adapter option is required; see Ordering

Information

on page 7 for details.

Warning!

Do not connect any equipment other than Precision

Digital’s expansion modules, cables, or meters to the

RJ45 M-LINK connector. Otherwise damage will occur to the equipment and the meter.

Note: More detailed instructions are provided with each optional serial communications adapter. Note: Refer to the ProVu® 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.

Changes made to the Serial menu are initialized after the MENU key is pressed or after navigating through the t-byte parameter.

72


Select Menu (SElect)

The Select menu is used to select the signal input conditioning function applied to the inputs (linear, square root, programmable exponent, or round horizontal tank), math function for A & B, constants, low-flow cutoff, and analog output programming. Multi-point linearization is part of the linear function selection.

73


Signal Input Conditioning (Functn)

The Function menu is used to select the input-to-output transfer function applied to the input signal: linear, square root, programmable exponent, or round horizontal tank volume 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 (Square)

The square root function is used to calculate flow measured with a differential pressure transmitter. The flow rate is proportional to the square root of the differential pressure. Scale the meter so that the low input signal (e.g. 4 mA) is equal to zero flow and the high input signal

(e.g. 20 mA) is equal to the maximum flow.

Programmable Exponent Linearization (Prog E)

The programmable exponent function is used to calculate open-channel flow measured with a level transmitter in weirs and flumes. The flow rate is proportional to the head height. Scale the meter so that the low input signal (e.g. 4 mA) is equal to zero flow and the high input signal (e.g. 20 mA) is equal to the maximum flow. This method works well for all weirs and flumes that have a simple exponent in the flow calculation formula.

For weirs and flumes with complex exponents it is necessary to use a strapping table and the 32-point linearization of the meter.

74


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 each channel 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.

Round Horizontal Tank Linearization (rHt)

This function is used to calculate volume in a round horizontal tank with flat ends. The volume is calculated based on the diameter and length of the tank. The tank’s dimensions can be entered in inches or centimeters; the meter automatically calculates the volume in gallons or liters. After entering the dimensions, complete the scaling process with the display values calculated by the meter. The meter can be re-scaled to display the volume in any engineering unit without the need to reenter the dimensions again.

Note: After Scale is displayed continue pressing the Enter button until the meter completes the scaling of the input and display values.

75


Changing the Volume from Gallons to Liters

In the above graphic, entering the 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 Upper 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.

Math Function (math)

The Math menu is used to select the math function that will determine the channel C value. These math functions are a combination of input channels A and B, and will display when channel C is selected in the

Math Constants (Const)

The Math Constants menu is used to set the constants used in channel

C math. The math functions include input channel A and B, as well as the adder constant P, and factor constant F.

The Adder constant (P) may be set from -99.999 to 999.999.

The Factor constant (F) may be set from 0.001 to 999.999.

The chart on page 76 details the math functions that may be selected in the Math Function menu.

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 to 999999. The meter will display zero below the cutoff value. Programming the cutoff value to zero disables the cutoff feature.

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

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

77


Analog Output Source

The analog output source can be based on either of the input channels

(Ch-A, Ch-B), the math channel (Ch-C), maximum stored value of either input channel (Hi-A, Hi-B), minimum stored value of either input channel

(Lo-A, Lo-B), relay set points, or the Modbus input.

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.

78


Programmable Function Keys User Menu (user)

The User menu allows the user to assign the front panel function keys

F1, F2, F3, F4 (digital input) and up to eight digital inputs to access most of the menus or to activate functions immediately (e.g. Reset max

& min). F4 is a digital input on the signal input connector. Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter (e.g. Alarms, relay acknowledgement, etc.).

Internal Calibration (ICAL)

The meter is factory calibrated prior to shipment to read in milliamps and volts depending on the input selection. The calibration equipment is certified to NIST standards.

The use of calibrated signal sources is necessary to perform the internal calibration of the meter.

Check calibration of the meter at least every 12 months. Each input and input type 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 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. Select channel A (Ch-A) or channel B (Ch-b) and press enter.

81


4. 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:

5. 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.

6. 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.

7. Set the display value to correspond to the input signal being calibrated, typically 4.000 mA.

8. The display moves to the high input calibration (C Hi). Apply the high input signal and press Enter.

9. 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 graphic above 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.

82


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 input 2 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.

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

4-20 mA

10 VDC

Input 1 & Input 2 Span

Meter Copy Function (Copy)

The Copy function is used to copy (or clone) all the settings from one meter to other meters requiring exactly the same setup and programming (i.e. type of input, scaling, decimal point, filter, bypass, etc.).

Warning!

Only the PDA1200 meter copy cable must be used for meter-to-meter interfacing.

Using standard CAT5 or other cable will cause damage to both meters.

Copy Function Requirements

To successfully copy settings from one meter to another, both meters must have the same software version and the same baud rate setting.

See Determining Software Version, page 87 for instructions.

83


Meter Copy or Cloning Instructions


!

Caution!

Do not connect the two meters to the same signal source while cloning. Internal calibration may be affected.

1. Connect two meters using a PDA1200 meter copy cable.

Warning!

Using standard CAT5 or other cable will cause damage to both meters. Use PDA1200 meter copy cable only.

2. Do not connect the two meters to the same signal source.

3. Power up both meters. Leave Clone meter in Run Mode. the Features menu of the Master meter; see

Advanced Features Menu

on page 66.

5. Scroll to the Copy function using the Up arrow button then press

Enter.

6. The meter displays the message Send. Press Enter, the display flashes while sending data. The message done is displayed when copying is completed.

7. The Clone meter displays the message CPY Rc while being programmed then the message done when copying is completed.

The meter initializes and returns to Run Mode using the same settings as the Master.

8. If meter to be cloned does not respond to the data being sent, refer to Copy Function Requirements above.

84


METER OPERATION

The meter is capable of accepting two input channels (A and B) of either current (0-20 mA, 4-20 mA) or 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).

A math function channel (C) is available to perform operations on channel A and B, with adder and factor constants, and display the results. Engineering units or tags may be displayed with these three channels.

The dual-line display can be customized by the user. Typically the upper display is used to display the math channel C, while the lower display is used to alternate between displaying input channels A and B.

Additionally the meter can be set up to display any input or math channel on the upper display and a unit or tag on the lower display. The relays and analog output can be programmed to operate based on any input or math channel.

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.

85


F4 Operation

A digital input, F4, 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 to COM, or with an active low signal.

During operation, F4 operates according to the way is has been programmed in the Advanced Features – User menu.

Maximum/Minimum Readings

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

1. Display briefly by assigning to the F1-F3 function keys or to the digital inputs in the User menu.

2. Display continuously by assigning either display to max/min through the Display menu.

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

To display max and min channel A reading using function key with factory defaults:

1. Press Up arrow/F2 button to display minimum reading of channel A since the last reset/power-up. The display will then display the maximum reading of channel A since the last reset/power-up.

2. Press the Up arrow/F2 button again to display the minimum reading of channel A since the last reset/power up.

3. To reset max/min press Right arrow/F1 button to access the Reset menu. The max & min displays are reset to actual values.

4. Press Menu to exit max/min display reading.
