Introduction

This analog input process meter is a multi-purpose, easy-to-use digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. Its superluminous LED digits make it easily readable in smoke, dust, fog, and, with the optional sunlight readable display, even direct sunlight. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the front panel buttons can be custom-programmed for a specific 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.

The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitter 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 meter has the following: four SPDT relays, 4-20 mA output, and two 24 VDC power supplies. The meter’s capabilities may be enhanced by adding the following external expansion modules: four SPST relays (creating an eight-relay process meter), two digital I/O modules with four inputs and four outputs each, and USB, RS-232 or RS-485 communication adapters.

The eight 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 options make this meter an excellent addition to any system.

There is no need to remove the meter from its case to complete the installation, wiring, and setup of the meter for most applications. Instructions are provided for changing the transmitter power supply to output 5 or 10 VDC instead of 24 VDC, see page 10.

Unpacking

Remove the meter from box. Inspect the packaging and contents for damage. Report damages, if any, to the carrier. If any part is missing or the meter malfunctions, please contact your supplier or the factory for assistance.

Panel Mounting Instructions

• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x 45 mm). Refer to Figure 1 below, for more details.

• Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.

• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Recommended minimum panel thickness to maintain Type 4X rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.

• Remove the two mounting brackets provided with the meter (back-off the two screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the bracket toward the front of the case and remove).

• Insert meter into the panel cutout.

• Install mounting brackets and tighten the screws against the panel. To achieve a proper seal, tighten

the mounting bracket screws evenly until meter is snug to the panel along its short side. DO NOT OVER TIGHTEN, as the rear of the panel may be damaged.

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.

Modbus RTU Serial Communications

Serial communications connection is made to an RJ45 connector labeled M-LINK on Figure 6. For interfacing to the meter, use the PDA1232 for RS-232 or the PDA1485 for RS-485. The same port is used for interfacing with all expansion modules (e.g. external relays, digital I/O).

Relay Connections

Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY4 on Figure 6. Each relay’s C terminal is common only to the normally open (NO) and normally closed (NC) contacts of the corresponding relay. The relays’ C terminals should not be confused with the COM (common) terminal of the INPUT SIGNAL connector.

Figure 11. Relay Connections

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:

Figure 12. 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.

Figure 13. Low Voltage DC Loads Protection

RC Networks Available from Automation Products Group

RC networks are available from Automation Products Group 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.

External Relays & Digital I/O Connections

The relay and the digital I/O expansion modules PDA1004 & 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.

Figure 18. Digital I/O Module Connections

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 35). 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.

Din Mounted Digital Display Instruction Manual

Programming the Meter (prog)

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

• 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.

• Use the Scale menu to scale the process input (e.g. 4-20 mA). A calibrated signal source is not needed to scale the meter.

• Use the Calibrate menu to apply a signal from a calibrator or a flowmeter.

• The meter is a single input meter with dual-scale capability.

The Program menu contains the Scale and the Calibrate menus. 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 under the Multi-Point Linearization (Linear) menu selection prior to scaling and calibration of the meter, see page 41 for details.

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.

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, page 38.

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 page 41 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 Application

The analog input can be displayed in two different scales, by enabling the dual-scale feature (d-SCAL) in the Setup-Input menu, see page 20.

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.

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.

Din Mounted Digital Display Instruction Manual

Note: To scale the meter without a signal source refer to Scaling the Meter (SCALE), page 23.

Warm up the meter for at least 15 minutes before

performing calibration to ensure specified accuracy.

Calibrating the Meter with External Source (Cal)

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.

The following graphic shows relay 1 action setup; relay 2-8 are set up in a similar fashion.

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.

Din Mounted Digital Display Instruction Manual

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.

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.

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)

The loop break feature is associated with the 4-20 mA input. 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)

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.

Signal Loss or Loop Break Relay Operation

The following graph shows the loop break relay operation for a high alarm relay.

When the meter detects a break in the 4-20 mA loop, the relay will go to one of the following selected actions:

1. Turn On (Go to alarm condition)

2. Turn Off (Go to non-alarm condition)

3. Ignore (Processed as a low signal condition)

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

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 visualonly 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).

Warning!

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

Latching and Non-Latching Relay Operation

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

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

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 (A-man)

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)

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.

Latching Relay (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 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 14).

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

Figure 20. Acknowledge Relays w/Function Key or Digital Input

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 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 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.

2. Relays 3 and 4 are set up for pump alternation.

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 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 restart 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 trip the relay.

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.

Din Mounted Digital Display Instruction Manual

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.

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.

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.

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, page 19.

Din Mounted Digital Display Instruction Manual

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.

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.

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 the rounding selected. See examples below:

Din Mounted Digital Display Instruction Manual

Warning!

Do not connect any equipment other than Automation Products Group’s expansion modules, cables, or meters to the RJ45 M-LINK connector. Otherwise damage will occur to the equipment and the meter.

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 onboard micro USB connection. For ongoing digital communications with a computer or other data terminal equipment, an RS-232, or RS-485 option is required; see Ordering Information on page 5 for details.

Note: More detailed instructions are provided with each optional serial communications adapter.

Note: Refer to the Modbus Register Tables located at www.apgsensors.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 signal input 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.

Signal Input Conditioning (Functn)

The Function menu is used to select the signal input 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.

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 oddshaped 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. 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.

Din Mounted Digital Display Instruction Manual

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 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.

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 (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 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.

Programmable Function Keys User Menu (user)

The User menu allows the user to assign the front panel function keys F1, F2, and F3, the digital input F4 (a digital input located on the signal input connector), and up to eight additional digital inputs 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.

Up to eight 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.

Function Keys & Digital I/O Available Settings

Refer to the following table for descriptions of each available function key or digital I/O setting.

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.

Din Mounted Digital Display Instruction Manual

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.

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.

Internal Source Calibration (ICAL)

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.

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 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.

Error Message (Error)

An error message indicates that the calibration or scaling process was not successful. 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.

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 by the user to operate in such a way as to satisfy a 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.

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 reading using function key with factory defaults:

1. Press Up arrow/F2 button to display maximum reading since the last reset/power-up.

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

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

To display max/min readings continuously:

Assign either display to Max (d Hi), Min (d Lo), or toggle between Max and Min (d HL) every 10 seconds.

Troubleshooting

The rugged design and the user-friendly interface of the meter should make it unusual for the installer or operator to refer to this section of the manual. However, due to the many features and functions of the meter, it’s possible that the setup of the meter does not agree with what an operator expects to see. If the meter is not working as expected, refer to the Diagnostics menu and recommendations below.

Diagnostics Menu (diag)

The Diagnostics menu is located in the Advanced Features menu, to access Diagnostics menu see Advanced Features Menu, page 38.

This menu allows the user to test the functionality of all the meter LEDs, check the meter’s software and version information, and erase the MeterView Pro software installation files from the meter. Press the Enter button to view the settings and the Menu button to exit at any time. For a description of the diagnostic messages, see Advanced Features Menu & Display Messages, page

38.

Determining Software Version

To determine the software version of a meter:

1. Go to the Diagnostics menu (diAG) and press Enter button.

2. Press Up arrow button and scroll to Information menu (Info).

3. Press Enter to access the software number (SFT) and version (UER) information. Write down the

information as it is displayed. Continue pressing Enter until all the information is displayed.

4. The meter returns to Run Mode after displaying all the settings.

Reset Meter to Factory Defaults

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.

Instructions to load factory defaults:

1. Enter the Advanced Features menu. See Advanced Features Menu, page 38.

2. Press Up arrow to go to Diagnostics menu

3. Press and hold Right arrow for three seconds, press Enter when display flashes reset. Note: If Enter is not pressed within three seconds, the display returns to the Diagnostics menu.

4. The meter goes through an initialization sequence (similar as on power-up), and loads the factory default settings.

Note: The dual-scale selection for some level applications (d-SCAL) is not reset to the single scale factory

default. This can be changed using the Setup – Input menu.
