Introduction

The ProtEX-MAX PD8-6210 offers all the functionality of the ProVu PD6210 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear.

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 13: AC and DC Loads Protection

Choose R and C as follows: R: 0.5 to 1  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 controller's relay screw terminals. An RC network may also be installed

across the load. Experiment for best results.

The PD6210 is factory calibrated prior to shipment to read in milliamps and volts depending on the input selection. The calibration equipment is traceable to NIST standards.

WARNING

Take caution when cleaning the window glass as it may result in unintentional SafeTouch button events. Only clean the ProtEX-MAX when the system is safely shut down, and inspect the ProtEX-MAX for proper configuration prior to system restart.

Basic Operation and Programming

Overview

There are no jumpers to set for the meter input selection. Setup and programming may be done through the infrared through-glass SafeTouch buttons, or using the

mechanical buttons when uncovered. There is a slide switch located on the connector board. This is used to enable or disable SafeTouch Buttons.

After power and input signal connections have been completed and verified, apply power to the meter.

SafeTouch® Buttons

The ProtEX-MAX is equipped with four sensors that operate as through-glass buttons so that it can be programmed and operated without removing the cover (and exposing the electronics) in a hazardous area.

These buttons can be disabled for security by selecting DISABLE on the switch labeled NO-CONTACT BUTTONS located on the connector board.

To actuate a button, press one finger to the glass directly over the marked button area. Then retract finger more than three inches from the glass before pressing the next button. When the cover is removed, the four mechanical buttons located next to the sensors are used. The sensors are disabled when a mechanical button is pressed and will automatically be re-enabled after 60 seconds of inactivity.

The SafeTouch Buttons are designed to filter normal levels of ambient interference and to protect against false triggering, however, it is recommended that the SafeTouch Buttons be disabled (slide switch to LOCK) if there is an infrared interference source in line-of-sight to the display.

The SafeTouch Buttons are configured by default to duplicate the function of the front panel mechanical pushbuttons associated with the integrated meter. The symbols by each SafeTouch button correspond to a mechanical button as shown in the table on the next page.

SafeTouch Button Tips:

• To the extent possible, install the display facing away from sunlight, windows, reflective objects and any sources of infrared interference.

• Keep the glass window clean.

• Tighten the cover securely.

• Use a password to prevent tampering.

Only STOP Button Enabled if a Batch is Running During a batch process, only the pause/stop functions of the

STOP button will function. No other buttons will be functional.

Controller Operation

The PD6210 controller 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).

These signals are scaled to represent rate in engineering units from -99999 to 999999. The default configuration displays batch total on the upper display, and a selection of rate, grand total,

batch count, and preset on the lower display. When in pause or stop mode, the display will alternate the numeric value with the run status in the upper

display and the display label for the lower display. The controller has up to 4 relays on board which are used to either control the batch process in single or

multi-stage batch control, or as alarms that will be active when the batch process is running. A 4-20 mA output option is also available for retransmitting the process variable analog or pulse signal.

Batch Control Operation Example

The following example shows how two stage batch control functions with a PD6210. This setup will establish a 55 gallon preset for the batch, with a main valve (high flow) that will close at 50 gallons, and a trickle valve (low or restricted flow) that will close at 55 gallons. After the batch, the preset will be changed to 100 gallons.

Two-Stage Batch Control Setup Using Relays 1 & 2

The following table shows the parameters as they appear within the Setup menu entry relay.

The operation of relay 2 has already been assigned for multi-stage control preclose, and will not appear as a selection in the relay menu.

If only one stage batch control was desired, with one relay for control, then one would set the assignment of relay 2, assign2, to off, rate, or grand total.

The following pages show an illustration of how the above settings control the batch operation. The display assignment is the default.

Batch Control Operation

1. A new container is prepared for the batch. Both valves are closed. Note that display line 1 may show

the batch total from the last batch.

2. The START button is pressed. Both valves open. The barrel begins to fill as the total being dispensed

is displayed on line 1. Line 2 shows the rate and units, alternating.

3. When the batch total reaches 50 gallons, the preset (55) minus the preclose amount (5) for relay 2,

relay 2 deactivates to close the main valve. The barrel fills more slowly as a result, improving accuracy.

4. When the batch total equals the preset, relay 1 deactivates, closing valve 1. Filling stops.

5. The BATCH button is pressed, and a new preset is entered, 100 gallons, and the enter/STOP button is

pressed to confirm it.

6. The new batch begins when the START button is pressed, so both relays activate and both valves

open.

Additional Features

At any time during the batch, the STOP button may be pressed to pause the batch. When paused, the START button will continue the batch, and pressing the STOP button again will cancel the batch.

When in STOP mode, the STOP button may be pressed to cycle through alternative parameters to be displayed on the lower display, including the grand total, batch count, and preset.

The grand total and batch count may be reset in the reset menu by pressing the MENU button and entering the reset menu. It may also be reset with digital inputs.

Scaling and Calibration

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

• There is no need to recalibrate the controller when first received from the factory.

• All inputs are factory calibrated. The calibration equipment used is traceable to NIST standards.

• Use the Scale menu to enter the scaling without a signal source.

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

Setting the Input Signal (Input)

Enter the Input menu to set up the controller to display current (mA) or voltage (volt) inputs. The current input is capable of accepting any signal from 0 to 20 mA. Select current input to accept 0-20

mA or 4-20 mA signals. The voltage input is capable of accepting any signal from -10 to +10 VDC. Select voltage input to accept 0-

5, 1-5, 0-10, or 10 VDC signals.

Setting the Totalizer and Batching Features (total)

After the input type is entered, set the total parameter to “Yes” to enable batch control (this is set by default). If the total features are disabled, most batching features and functions are hidden from the menus.

Setting the Input Units or Custom Tags (units)

Enter the input unit or custom tag that will be displayed if alternating rate, total, or grand total and units is selected in the units menu, or d unit is selected as the Lower display parameter. See the flow chart on page 36 to access the display menu to show the unit or tag on the Lower display. The engineering units or custom legends can be set using the following 7-segment character set:

Notes: Degree symbol represented by (<) if programming with MeterView® Pro. The letters “m” and “w” use two 7-segment LEDs each; when selected the characters to the right are shifted

one position. Press and hold up arrow to auto-scroll the characters in the display.

Setting the Decimal Point (dEc pt)

The decimal point may be set with up to five decimal places or with no decimal point at all. The rate, total, and grand total decimal points are independent.

Press the Up arrow to move the decimal point one place to the left. Press the Right arrow to move the decimal point one place to the right.

Programming the Batch Controller (prog)

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

• The PD6210 is factory calibrated prior to shipment to read in milliamps and volts depending on the input selection. The calibration equipment is traceable to NIST standards.

• Use the Scale menu to scale process inputs without a signal source. A calibrated signal source is not needed to scale the controller.

The Program menu contains the following menus:

1. Scale without a signal source

2. Calibrate with a calibrated signal source

3. Total time base & conversion factor

4. Grand total time base & conversion factor

5. Total reset mode for total & grand total

The process inputs may be calibrated or scaled to any display value within the range of the controller.

Additional parameters, not needed for most applications, are programmed in the Advanced Features menu; see ADVANCED OPERATION AND PROGRAMMING, page 47.

Input Calibration Method (InCAL)

There are three methods of calibrating (or scaling) the display to show the correct engineering units.

• Use the Factor menu to enter a K-Factor. (Pulse input models only.)

• Use the Scale menu to enter the scaling without a signal source.

• Use the Calibrate menu to apply a signal from a signal source.

Note: The K-Factor, 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 for Scale and Calibrate accordingly under the Number of Points (nopts) menu selection prior to scaling and calibration of the meter, see page 53 for details.

Scaling the Controller (SCALE)

The process inputs (4-20 mA and 10 VDC) and frequency inputs can be scaled to display the process variable in engineering units.

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

Error Message (Error)

An error message indicates that the calibration or scaling process was not successful. After the error message is displayed, the controller 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.

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 2 signals required to complete the calibration or scaling of the controller.

To scale the controller without a signal source, refer to

Scaling the Controller (SCALE) page 33.

Warm up the controller for at least 15 minutes before

performing calibration to ensure specified accuracy.

Time Base, Total Conversion Factor & Total Reset

The time base, total conversion factor, and total reset menus are located in the Program menu. The total and grand total have their own independent settings. This means that one can be displaying the

value in gallons while the other displays in million gallons, liters, m3, etc.

Batch Start Mode (mode)

The batch controller may operate in manual or automatic mode. In manual mode, the controller operates as defined in Controller Operation as described on page 24. In automatic mode, the batch process will automatically begin after a completed batch. The time delay for the restart may be 0.1 to 999.9 seconds (t dly). Automatic batch start will only occur after a successful batch. A manually stopped batch will require a manual start to begin a new batch process.

Grand Total Reset

The grand total can be programmed for manual or automatic reset. In the automatic reset mode, a programmable time delay is available to reset the grand total after the assigned preset is reached.

Non-Resettable Totalizer

The total and grand total can be password-protected to prevent unauthorized resets. The grand total can be programmed as a non-resettable total, see page 46 for details.

Calibrating the Controller with External Source (Cal)

The controller can be calibrated to display the process variable in engineering units by applying the appropriate input signal and the corresponding display value.

The use of a calibrated signal source is strongly recommended to calibrate the controller.

are assigned.

Relay Assignment (Assign)

The relays can be assigned to any of the following parameters:

1. Rate for low or high alarm indication

2. Total for batch control relays

3. Grand total for alarm indication

Note: Relay 1 should always be assigned to “total” for batch control applications.

Setting the Relay Action

Operation of the relays is programmed in the Action menu. The relays are commonly set up for any of the following modes of operation:

1. Always set to Auto for Batch control operation. Also for automatic reset (non-latching) of alarms.

2. Sampling (the relay is activated for a user-specified time)

3. Off (relay state controlled by Interlock feature)

In addition, the following relay actions may be programmed. These actions are not appropriate for batch control applications, but may be used then the controller is in other applications.

4. Automatic + manual reset when not in a batch process (non-latching)

5. Latching (manual reset only, when not in a batch process)

6. Latching with Clear (manual reset only when not in a batch process after alarm condition has cleared)

7. Pump alternation control (automatic reset only, for level applications, unrelated to batch control.)

Setting Batch Control Relays

Operation of batch control relays are programmed in the Assign menu by selecting total as the assignment. Relays set to total beyond the first will include a preclose parameter (precls) option. Selecting yes for precls will enable multi-stage batching with preclose, and the valve will close prior to the end of the batch at volume equal to the preset value minus the preclose amount entered. Selecting no for precls will have the relay perform identically to the first batch control relay set to total.

Programming Alarm 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. Failsafe mode should not be used on batch relays assigned to total.

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. Rate alarm relays may be programmed to go to one of the following conditions when the controller 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 (Process 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.

Relay Operation Details

Overview

The relays of the controller can serve three roles, as batch control relays for single or multi-stage batching, as rate, or grand total alarm, or as a sampling relay based on grand total or rate alarm.

These capabilities include front panel alarm status LEDs and 2 or 4 internal relays. The relays used for batch control (total) are activated when the batching process starts, and deactivate

when the batch total is reached, minus any preclose amount programmed for batch (total) relays after the first.

For an example of batch control operation, see Batch Control Operation Example on page 25. Typical applications for alarms are low and high flow alarms or grand total limit alarms. Note that rate

alarms are only enabled during a batching process, and deactivate when the processes is stopped. The relays can also be set for sampling, where the relay will activate for a specific amount of time after a

certain grand total has been reached (ie: 2 second sample relay activation every 100 gallons batched). There are three basic ways the relays can be used:

1. Batch Control (Total)

2. High or Low Alarms for Rate or Grand Total

3. Sampling (Based on Grand Total and Sample Time)

Relays Initialization

Batch control (total) relays will activate when the start function is enabled, such as when the START button is pressed. Rate alarm relays will enable and initialize to their programmed states when the batch process is started. Grand total alarm relays will initialize to their programmed state at controller power-up.

Fail-Safe Operation

The following table indicates how alarm 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 controller is off.

Front Panel LEDs

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

The controller 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. Note that rate alarms are only enabled during a batching process, and deactivate when the processes are stopped.

Latching relays, or relays with manual reset, are not recommended when using this controller for batch control, as the manual reset will not be acknowledged during a batch process, when the rate alarms are active. For information on latching and manual reset alarms, see the PD6200 and PD6300 instruction manuals available at www.predig.com.

In this application, the controller 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.

Pump Alternation Control

Pump alternation control is not recommended when using this controller for batch control, as it is used only in level applications, and not with rate, total, or batching applications. For information on using pump alternation control for level, see the PD6200 and PD6300 instruction manuals available at www.predig.com.

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 3 & 4 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).

Sample Relay Operation

The sampling function allows the operator to set a set point for a “sampling” relay. This can be done for the rate, total, or grand total. Each time the relay reaches the set point, it will close that relay’s contacts for a programmed period of time

A rate sampling relay will activate for the sample time (sam t), up to 600.0 seconds, every time the set point rate is reached.

A total sampling relay will activate for the sample time (sam t), up to 600.0 seconds every time the process has batched the amount programmed for the set point, and every time this amount has been batched afterward. (See the diagram below for more details). The utility of this function can, of course, be expanded beyond sampling and be used whenever a timed relay output closure is required when the batch total interval reaches a certain set point.

Relay and Alarm Operation Diagrams

Page 43

ProtEX-MAX PD8-6210 Explosion-Proof Analog Input Batch Controller Instruction Manual

Rate 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 600.0 seconds.

Total Relay Sampling Operation

When the batch total reaches 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 value is added to the batch total.

Signal Loss or Loop Break Relay Operation

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

When the controller 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 (Process as a low signal condition)

For instructions on how to

program numeric values

see Setting Numeric

Values, page 30.

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.

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 rate 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 rate display values.

pause/stop functions of the STOP button; the default programming of the F3 key. No other functions, including min/max display, manual alarm reset, or total reset, will function while a batch is running.

Changing the programming of the F1-F3 function keys will disable the default batch operation of these keys, and is not recommended for batch control applications.

Note that changing default the programming of the upper or lower displays will interfere with seeing the batch total (upper display) or rate (lower display) of the batch process.

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 following table shows the default setting for each of the function keys.

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.

Advanced Setup and Calibration

Multi-Point Calibration & Scaling

The controller 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. See page 53 for details.

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 digital inputs in the User menu.

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

Any of the digital inputs can be programmed to reset the max & min readings.

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.

Warning!

Do not connect any equipment other than Precision Digital’s expansion modules, cables, or controllers to the RJ45 M-LINK connector. Otherwise damage will occur to the equipment and the controller.

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

Modbus RTU Serial Communications (serial)

The controller 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 ProVu® Modbus Register Tables located at www.predig.com for details.

When using more than one controller in a multi-drop mode, each controller must be provided with its own unique address. The controller 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.

Serial Communications Overview

RS-232 and RS-485 are standard interfaces approved by the Electronic Industries Alliance (EIA) for connecting serial devices. In EIA terms, the device (e.g. meter) that connects to the interface is called a Data Communications Equipment (DCE) and the device to which it connects (e.g. the computer) is called a Data Terminal Equipment (DTE).

RS-485 can support multi-point connections per line because it uses lower-impedance drivers and receivers.

Line drivers and receivers are used to exchange data between two or more points (nodes) on a serial communications network. Reliable data communications can be difficult in the presence of induced noise, ground level differences, and other hazards associated with installation of a network. When communicating at high data rates, or over long distances in real world environments, RS-232 is often inadequate. The differential data transmission of RS-485 offers superior performance in most applications. Differential signals can help nullify the effects of ground shifts and induced noise signals that can appear as common mode voltages on a network.

A multi-point network consists of multiple drivers and receivers connected on a single bus, where any point (node) can transmit and/or receive data. RS-485 allows multiple drivers and receivers on the same two-wire or four-wire system. The RS-485 standard specifies up to 32 drivers and 32 receivers on a single bus, but with the introduction of "automatic" repeaters and high-impedance drivers/receivers, this number can be extended to hundreds of points (nodes) on a network.

The cabling used for an RS-485 serial communications network should always be a high quality cable such as Belden 8162 or Alpha 6203C. A two-wire system requires two twisted pairs, and a four-wire system requires three twisted pairs (the extra twisted pair is needed for the signal ground).

Figure 19 illustrates how to connect a general four-wire network (a four-wire network actually contains 5 wires).

Figure 19: General Four-Wire Network Connection

Figure 20 illustrates how to connect a general two-wire network (a two-wire network actually contains 3 wires). Note that the PDA7485 and PDA8485 have DIP switches that allow for two-wire connections without the need to externally wire the DO to the DI and the /DO to the /DI (see the converter section for complete details).

Select Menu (SElEct)

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

Signal Conditioning Selection (Functn)

The Function menu is used to select the signal conditioning function applied to the input: linear, square root, or programmable exponent. The multi-point linearization is part of the linear function selection.

Controllers 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)

Controllers are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points can be selected 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.

Low-Flow Cutoff (CutofF)

The low-flow cutoff feature allows the controller to be programmed so that the often-unsteady output from a differential pressure transmitter, at low flow rates, always displays zero on the controller.

The cutoff value may be programmed from 0 to 999999. The controller will display zero below the cutoff value. Programming the cutoff value to zero disables the cutoff feature.

Total and Grand Total Count Direction (Count)

By default, the batch total and grand total count up during batch processes. Count parameter allows this to change. When set to count down, the batch total will count down from the preset to 0. When set to count down, the grand total will count down from a set value to zero.

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 rate/process variable, total, grand total, maximum or minimum value reached by the rate/process, one of the set points, or the Modbus PV input.

Analog Output Calibration

To perform the analog output calibration, it’s 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.

ProtEX-MAX PD8-6210 Explosion-Proof Analog Input Batch Controller Instruction Manual

Note: The PD6210 is factory calibrated prior to shipment to read in milliamps and volts depending on the input selection. The calibration equipment is traceable to NIST standards.

Notes:

1. If controller 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 controller to warm up for at least 15 minutes before performing the internal source calibration procedure.

Internal Source Calibration (ICAL)

The use of a calibrated signal source 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 controller at least every 12 months. Each input type 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 controller.

2. Press the Up arrow button to scroll to the Internal calibration menu (ICAL) and press Enter.

3. The controller 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 controller displays low input current message (C lo). Apply the low input signal and press Enter.

The display flashes for a moment while the controller 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 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 value within the range of

the controller.

• 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. After the error message is displayed, the controller 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 2 signals required to complete the calibration or scaling of the controller.

Troubleshooting

Due to the many features and functions of the controller, it’s possible that the setup of the controller does not agree with what an operator expects to see.

If the controller 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 Operation and Programming, page 47.

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 48.

Determining Software Version

To determine the software version of a controller:

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 controller returns to Run Mode after displaying all the settings.

Reset Controller 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 Operation and Programming, page 47.

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

WARNINGS

• Installation and service should be performed only by trained service personnel. Service requiring replacement of internal sub-components must be performed at the factory.

• Disconnect from supply before opening enclosure. Keep cover tight while circuits are alive. Conduit seals must be installed within 18" (450mm) of the enclosure.

• Verify that the operating atmosphere of the instrument is consistent with the appropriate hazardous locations certifications.

• If the instrument is installed in a high voltage environment and a fault or installation error occurs, high voltage may be present on any lead

• Read all product labels completely and follow all instructions and requirements listed on the labels for installation or service.

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