is loaded into the controller and connects and installs
directly to your PC with a USB cable. We recommend
that the first thing you do after taking the controller out
of the box is connect the ProtEX-MAX to your PC with
the provided USB cable – do not use a different cable.
DO NOT apply AC or DC power to the controller while
your PC is connected to the controller as it will disrupt
the USB connection. You don’t even have to apply an
input signal.
MeterView Pro programming software is intuitive, and
most customers can get their controller programmed
as they like without even looking in the manual.
Watch MeterView Pro Software Video at
www.predig.com/meterviewpro
In addition to programming, the software may be used
to perform many useful tasks:
• Start, Pause, Stop the batch
• Change preset & pre-close settings
• Reset total & grand total
• Test the relays functionality
• Monitor the batch process
• Datalogging using your PC
• Generate & save program files for later use
Once your controller is programmed the way you want
it, you can wire it up for your application per the
instructions in this manual and install it. If you find that
you need to make adjustments to the programming
after the controller is installed, you can use the
programming buttons and the instructions in this
manual to do so.

Introduction
The PD8-6310-WM ProtEX-MAX is an explosion-proof,
NTEP® Certified pulse input batch controller certified
as a weighing and measuring device that provides
simple independent batch control operations where
local control is preferred to expensive plant operation
systems. The controller features a dual-line display,
with a main display 0.60" (15 mm) high, and a second
display of 0.46" (12 mm) high superluminous LED
digits, which can be read in any lighting condition,
including direct sunlight. The controller is housed in a
die-cast aluminum, field-mountable, NEMA 4X/IP68
rated enclosure for convenient indoor and outdoor
installation.
The controller has a mechanically secured
programming lockout feature. A cable with
compression seal may be secured to prevent the
removal of the rear case, preventing access to the
programming lockout jumper.
The controller comes programmed for easy start,
pause, stop, and batch size (preset) changes. The
second display can be programmed to display rate,
grand total, batch count, or preset by cycling the Stop
(F3) button. Digital inputs come standard.
Single and multi-stage batching is possible with up to
four on-board relays. Each batch control relay may
have a unique preclose amount when used for
multi-stage batching. Manual start batching is default,
but automatic batching with a restart after a
programmed time delay from the completion of the
last batch is also possible.
Overrun correction adjusts the closing of the batch
control relays to adjust for inaccuracies from batch to
batch. This increases accuracy over time as systems
wear out. The overrun correction feature is capable of
compensating for inaccuracies of up to 1% of the
programmed preset value.
The controller accepts pulse (e.g. ±40 mV to ±8 V),
square wave (0-5 V, 0-12 V, or 0-24 V), open
collector, NPN, PNP, TTL or switch contact signals.
The PD8-6310-WM batch controller comes with four
SPDT relays, a 4-20 mA output, two 24 VDC power
supplies, five digital inputs and four digital outputs,
and RS-485 serial communications, making it an
excellent addition to any system.

The Only Explosion-Proof Batch Controller You Will Ever Need
The ProtEX-MAX PD8-6310-WM is an explosion-proof
batch controller with four internal relays that can be
used for single or multi-stage batch control.
The first thing you notice about the PD8-6310-WM is
its modern looking, rugged, die-cast aluminum
housing with convenient mounting flanges. Housed
inside this enclosure is a dual-line, 6-digit display that
is usually setup to show the current batch quantity
and the batch preset on the two lines. START, BATCH,
and STOP buttons (which can be operated remotely
or without removing the cover) come setup by default
for batch control operation. The START button starts
the batch. The BATCH button shows the preset value.
The STOP button pauses or stops the batch.
The controller has a mechanically secured
programming lockout feature. A cable with
compression seal may be secured to prevent the
removal of the rear case, preventing access to the
programming lockout jumper.
The PD8-6310-WM is approved as a complete product
by FM and CSA and also carries ATEX and IECEx
certification. One of the more convenient features of
the PD8-6310-WM is its through-glass SafeTouch
buttons which allow the controller to be operated
without removing its cover. Just put your finger on the
glass over the button to actuate it. The PD8-6310-WM can
also provide 5, 10, or 24 VDC to power the flowmeter.
A ProtEX-MAX batch controller can be programmed
for a wide variety of applications. Setup is easy for
single or multi-stage batching. Automatic overrun
correction keeps the batch size accurate, even over
time. The PD8-6310-WM can display the number of
batches that have been run and the total amount of
product that has been batched. These features and
capabilities can easily be programmed without
removing the cover using SafeTouch buttons in a
hazardous area or with free MeterView Pro PC-based
software in a safe area.

Easy Programming Methods
The ProtEX-MAX can be programmed in a hazardous
area with the through-glass SafeTouch buttons
without removing the cover, in a safe area with the
front panel push buttons with the cover removed, or in
a safe area with free, PC-based MeterView Pro
software. MeterView Pro is resident on the
ProtEX-MAX and is accessed by a provided USB
cable, so it is by far the easiest way to program the
ProtEX-MAX.
The controller comes from the factory pre-calibrated
for all pulse inputs, so the user need only set the
mV / PNP / NPN switch in the appropriate position
based on the input and also set the desired excitation
voltage level. Once programming is completed, the
controller can be locked with a password.
The ProtEX-MAX comes preloaded with free
MeterView Pro programming software that connects
and installs directly to your PC with a standard USB
cable, also provided free with each instrument. This
eliminates the need to insert CDs, install drivers, or
download software from the internet. When you
connect your ProtEX-MAX to your PC, MeterView Pro
is downloaded to your PC, the software automatically
selects the model you are programming, and you’re
ready to start programming immediately. Further
simplifying the programming process, the
ProtEX-MAX can be powered from the USB port, so
no need to apply external power while programming
your controller. In addition to programming, the
software will also allow you to monitor, and datalog a
ProtEX-MAX using your PC. You can also generate
and save programming files for later use.
Advanced Display Features
Display What You Want
The most common setup for these batch controllers is
to display the batch total on the main display and batch
preset on the second display. This allows the user to
monitor the batch as it progresses and compare it to
the total batch size. Other possible setups include
displaying the batch total and flow rate, batch total
and batch count, and batch total and grand total.
Batch Total & Preset Batch Total & Rate
Batch Total Batch Total
& Batch Count & Grand Total
Easy to Program
The controller may be calibrated using the K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor
(Factor) menu and select the decimal point with
highest resolution possible and program the k-factor
value (i.e. pulses/gal). The controller will automatically
calculate the flow rate using the k-factor and the time
base selected.
K-Factor Menu K-Factor Value
Super-Bright Display
The ProtEX-MAX comes standard with a super-bright
display, with LEDs that are visible even in direct
sunlight. The display also has up to eight levels of
adjustable intensity for optimum visibility in any
lighting condition.
Rounding for Even Steadier Display
The rounding feature is used to give the user a
steadier display with fluctuating signals. It causes the
display to round to the nearest value according to the
rounding value selected (1, 2, 5, 10, 20, 50, or 100).
For example, with a rounding value of 10, and an
input of 12346, the display would indicate 12350.

Batch Controller Capabilities
A ProtEX-MAX batch controller can be programmed
for a wide variety of single or multi-stage batching
applications and set up to run in either manual or
automatic operation. Batch size can be displayed on
the controller and is easily programmed and changed
if needed. The controller can even display the number
of batches that have been run. Automatic overrun
correction keeps the batch size accurate, even over
time and with system wear. The controller can display
the rate with a time base of seconds, minutes, hours
or days. The user can program a conversion factor,
configure a non-resettable grand total, and configure
password protection.
Manual or Automatic Batch Control
Batches may be started manually with the START
front panel button, or with a remote digital input
trigger. Batches may also be programmed to start
automatically after a 0 to 999.9 second delay after the
end of the last completed batch. A manually stopped
batch will only restart after the START button is
pressed or digital input triggered.
Automatic Overrun Correction
The ProtEX-MAX batch controller will correct for batch
overrun or shortages automatically. By tracking the
amount the batch was off by, the controller will
automatically adjust the batch by modifying the batch
relay deactivation time.
Single and Multi-Stage Batching
The ProtEX-MAX can be used as a single or
multi-stage batch controller. Relays assigned to the
total act as batch control relays, with additional relays
beyond the first including a preclose value. The
preclose deactivates the relay before the batch is
finished, to allow slower fill rates and a more accurate
batch finish. Each additional stage batching relay has
an individually programmable preclose amount.
Single Stage Batch Control
Multi-Stage Batch Control
Quick Preset Changes
The front panel BATCH key is configured by default to
access the preset menu. The preset may be changed
quickly and easily between batches without the need
to enter setup menus.
Non-Resettable Grand Total
The user can set up the grand total to be non-resettable
by entering a specific password. Once this is done,
the grand total can never be reset.
Total Conversion Factor
The user can enter a conversion factor that allows the
controller to display total in different units than the
rate. For instance, an operator could measure flow
rate in gallons per minute and grand total in millions of
gallons.
Grand Total & Rate Alarms
The ProtEX-MAX’s four internal relays can be set up
to alarm when the grand total reaches a user-defined
set point or when the rate is above or below a certain
value. Rate alarms are only activated when the
batching process is running. A variety of reset modes
are available and the user can also program time
delays and fail-safe operation.
F4 Digital Input
The digital input can be used for a variety of functions
such as starting or stopping a batch, resetting the total,
or resetting an alarm relay. This is ideal for installations
where the controller is inaccessible behind a cover, or
where an additional function key is needed for
customized operation.
Remote Operation of Controller
There are four digital inputs that can be programmed
to mimic the MENU, START, BATCH, and STOP
buttons that could be controlled by a control station*
suitable for location in a hazardous area.
* Control station must be approved for hazardous
locations

Physical Features
The ProtEX-MAX is designed for ease-of-use in safe
and hazardous applications. The ProtEX-MAX is
housed in a rugged NEMA 4X explosion-proof
enclosure, can operate over a wide temperature
range, includes removable screw terminal connectors,
has worldwide approvals for use in hazardous areas,
and features through-glass buttons for easy controller
operation without the need to remove the cover. All of
these features are backed by a 3-year warranty.
Super-Bright LED Display
The ProtEX-MAX features a dual-line 6-digit display
with super-bright LEDs, our brightest ever. These
allow the display to be read in any lighting condition,
even in direct sunlight.
SafeTouch Through-Glass 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 the DISABLE setting on the NO-CONTACT
BUTTONS switch located on the back of the
electronics module, inside the enclosure.
Rugged, Heavy-Duty Enclosure
The ProtEX-MAX is housed in a rugged NEMA 4X, 7,
& 9, IP68 die-cast aluminum enclosure, designed to
withstand harsh environments in safe and hazardous
areas over a wide temperature range.
Wide Viewing Angle
Customers can’t always look at the display from
straight on, so the window and display module have
been optimized to provide a wide viewing angle of
approximately ±40°; nearly twice that of the
competition.
Built-In Mounting Flanges
The ProtEX-MAX is equipped with four slotted flanges

Relay Connections
Relay connections are made to two six-terminal
connectors labeled RELAY1 – RELAY4. 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 19. Relay 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 activate the interlock relay. This
feature is enabled by configuring the relay, and the
corresponding digital input(s), see Setting Up the
Interlock Relay (Force On) Feature on page 50.
In the example below, an Interlock Contact switch is
connected to a digital input, which will be used to
force on (energize) the Interlock Relay. The Interlock
Relay and the Control Relay are connected in series
with the load.
• When the Interlock Contact is closed (safe), the
Interlock Relay energizes, allowing power to flow
to the Control Relay; the corresponding front
panel LED is on.
• When the Interlock Contact is open, the
corresponding front panel LED flashes (locked
out), the Interlock Relay is de-energized,
preventing power from flowing to the Control
Relay and the load.
Figure 20. Interlock Connection
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 21. 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.
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 22. 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.

Setup and Programming
The controller may either be scaled (SCALE) without applying an input, calibrated
(Cal) by applying an input, or you may use the K-Factor menu to match the batch
controller with a flowmeter’s k-factor (pulse/unit of measure).
The controller comes factory calibrated to NIST standards, so for initial setup, it is
recommended to use the K-Factor method or (SCALE) function.
Overview
There is one switch, located to the right of the input connector, which must be configured according to the input level
and type. The switch labeled P+/P- located in the center of the connections board is used to select the excitation
voltage (24 V*, 10 V or 5 V) which is supplied to the P+ and P- wiring terminals.
Setup and programming is done using MeterView Pro or through the programming buttons.
After power and input signal connections have been completed and verified, apply power to the controller.

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
DISABLE) 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 controller.
The symbols by each SafeTouch button correspond
to a mechanical button as shown in the above table.
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.

Setting the Input Signal (Input)
There is a switch, located to the right of the input
connector, which must be configured according to the
input level and type. For location of this switch, see
Pulse Signal Connections on page 28.
Jumper J4 located inside the meter, behind the input
signal connector, is used to select the excitation
voltage (24 V [Default setting], 10 V or 5 V) which is
supplied to the P+ and P- wiring terminals. For
location of this switch, see Controller Supply Voltage
Selection (P+, P-) on page 23.
Enter the Input menu to enable or disable the totalizer
features.
The controller may be calibrated using the K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor
(Factor) menu and select the decimal point with
highest resolution possible and program the K-factor
value (i.e. pulses/gal). The controller will automatically
calculate the flow rate using the K-factor and the time
base selected.
Setting the Totalizer & Batch Control 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 Second display parameter. See the
Setting the Display Parameter & Intensity (dsplay)
flow chart on page 42 to access the display menu to

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.
The decimal point selection should be made prior to
scaling, calibrating or programming the controller.
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)
The controller may either be scaled (SCALE) without
applying an input, calibrated (Cal) by applying an
input, or you may use the K-Factor menu to match the
rate/totalizer with a flowmeter’s k-factor (pulse/unit of
measure). The controller comes factory calibrated to
NIST standards, so for initial setup, it is
recommended to use the (SCALE) function.
The Program menu contains the following menus:
1. Input Calibration
a. Enter K-Factor
b. Scale without a signal source
c. Calibrate with a signal source
2. Total time base & conversion factor
3. Batch mode
a. Manual batch control
b. Automatic batch control
4. Grand total time base & conversion factor
5. Grand total reset mode
a. Manual reset
b. Automatic reset with time delay
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 Setup & Programming
on page 59.
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
• Use the Scale menu to enter the scaling without a
signal source.
• Use the Calibrate menu to apply a signal from a
signal source.
• The Scale, Calibrate, and K-Factor functions are
exclusive of each other. The controller uses the
last function programmed. Only one of these
methods can be employed at a time.
• The Scale and Calibrate functions can use up to
32 points (default is 2). The number of points
should be set in the Advanced menu prior to
scaling and calibration of the controller. See
Multi-Point Linearization (Linear) menu on page
62 for details.
K-Factor Calibration (Factor)
The controller may be calibrated using the K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor
(Factor) menu and select the decimal point with
highest resolution possible and program the k-factor
value (i.e. pulses/gal). The controller will automatically
calculate the flow rate using the k-factor and the time
base selected.
Page 40
PD8-6310 Explosion-Proof NTEP Certified Pulse Input Batch Controller
Instruction Manual
40
Scaling the Controller (SCALE)
The pulse 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.
Note: The display values (DiS 1 and DiS 2) need to be in
units of measure per second. For example, if the rate at
1000 Hz is 13.20 gal/min, this must be converted to gal/sec.
In this scenario, the numbers input into the SCALE menu
would be as follows:
InP 1: 0.0
DiS 1: 0.00
InP 2: 1000.0
DiS 2: 0.22
For instructions on how to program numeric values
see Setting Numeric Values, page 36.
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 allowed input span is 0.10 Hz, which is
the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling
of the controller.
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.
Time Base
The time base is the amount of time over which the
rate parameter should accrue. For example, if the rate
was ten and the time base was in minutes, then the
total would increase by ten every one minute.
Total & Grand Total Conversion Factor
The total & grand total conversion factor is the
amount by which the rate is multiplied before it is
added to the total or grand total.
For Example, if the rate was 10,000 gallons per
minute and the total conversion factor was 0.001, the
total would increase by 10 every minute. This is
useful, for instance, if you want to show rate in gallons
and total in thousands of gallons.

Batch Start Mode (nmode)
Manual Batch Control
The batch controller may operate in manual or
automatic mode. In manual mode, the controller
operates as described in Manual Batch Control on
page 55.
Automatic Batch Control
In automatic mode, the controller operates as
described in Automatic Batch Control on page 56.
The batch process will start when the operator
presses the START button and it will automatically
restart 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.
The totals can also be reset via the front panel button,
via a switch across the F4 terminal, digital inputs, or
via a Modbus command.
Non-Resettable Totalizer
The grand total can be programmed as a
non-resettable total, see Grand Total Reset Password
& Non-Resettable Total on page 52 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.
Notes:
1. The display values (DiS 1 and DiS 2) need to be in
units of measure per second.
2. Inputs for the above example are:
Input 1: 0.0 Hz; Display 1: 0.0 gallons/sec
Input 2: 1000.0 Hz; Display 2: 6000.0 gallons/sec
3. After completing the calibration, you can change the
time base to /min, /hour, or /day.
Warm up the controller for at least 15 minutes
before performing calibration to ensure specified
accuracy.

Display Menu
Display Intensity (d-Inty)
The controller has eight display intensity levels to give
the best performance under various lighting
conditions. Select intensity 8 for outdoor applications.
The default intensity setting is 6.
For direct sunlight readability, Sunbright display
models are highly recommended. See Ordering
Information on page 7 for details.
Display Configurations
The main and second displays may be assigned to
rate, total, grand total, batch count, preset, set points,
units (second display only), alternating R & T, R &
GT, preset & rate, max & min, or a Modbus display
register. Any rate/total/grand total display may be
programmed to alternate with a custom unit or tag.
The default display configuration consists of a main
display of batch total and a second display of the
batch preset.
The display can also be set up, so batch total is on
the main display and rate is on the second display.

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 or sampling
• Relay 1 should always be assigned to “total” for batch control applications.
Page 45
PD8-6310 Explosion-Proof NTEP Certified Pulse Input Batch Controller

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 can be 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 when 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 (not applicable 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
relay will include a pre-close parameter (precls)
option. Selecting yes for precls will enable
multi-stage batching with pre-close, and the valve will
close prior to the end of the batch at volume equal to
the preset value minus the pre-close 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: program set point above reset point.
Low alarm: 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.

Automatic Batch Control Operation
The following graph shows automatic batch operation.
When START is pressed, a short delay occurs before the low flow alarm sensing is activated. Each relay can be
programmed with additional ON delay to satisfy various conditions and applications.
1. START button is pressed
2. Both relays are energized opening both valves controlling the flow
3. At 50 gallons (pre-close = 5 gal), relay 2 closes the main valve
4. At 55 gallons (preset = 55 gal), relay 1 closes the dribble valve
5. After the Batch Time Delay elapses, a new batch starts automatically without the operator’s intervention.

Relay and Alarm Operation Diagrams
The following graphs illustrate the operation of the
relays, status LEDs, and ACK button.
High Alarm Operation (Set > Reset)
For Manual reset mode, ACK can be pressed anytime
to turn "off" relay. To detect a new alarm condition,
the signal must go below the set point, and then go
above it.
Low 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.
High Alarm with Fail-Safe Operation (Set > Reset)
Note: Relay coil is energized in non-alarm condition. In case
of power failure, relay will go to alarm state.
Low Alarm with Fail-Safe Operation (Set < Reset)
Note: Relay coil is energized in non-alarm condition. In case
of power failure, relay will go to alarm state.
Page 48
PD8-6310 Explosion-Proof NTEP Certified Pulse Input Batch Controller
Instruction Manual
48
Time Delay Operation
The following graphs show the operation of the time
delay function.
When the signal crosses the set point, the On time
delay timer starts and the relay trips when the time
delay has elapsed. If the signal drops below the set
point (high alarm) before the time delay has elapsed,
the On time delay timer resets and the relay does not
change state. The same principle applies to the Off
time delay.
Note: If “Automatic or Manual (A-nmAn)” reset mode is
selected, the LED follows the reset point and not the relay
state when the relay is acknowledged.
Total Relay Sampling Operation
When the total reaches the preset, the relay trips and
the sample time starts. After the sample time has
elapsed, the relay resets. The cycle repeats every
time the preset value is added to the total.

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 4 relays.
The relays used for batch control (total) are activated
when the batching process starts and deactivate
when the batch total is reached. The relays assigned
as pre-close are deactivated when the batch reaches
the preset value minus the pre-close value.
For an example of batch control operation, see Batch
Control Operation Example on page 54.
Typical applications for alarms are low flow and high
flow alarms or grand total limit alarms. Note that rate
alarms are only activated during a batch process and
deactivated when the process 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 (e.g. 10 seconds
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 alarm status LEDs on the front panel are
available on all controllers and provide status
indication for the following:
LED
Status
1
Batch Relay 1
2
Batch Relay 2
3
Low Flow Alarm
4
High Flow Alarm
The controller is supplied with 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 activated during a batch process, and
they are deactivated when the process is 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 PD8-6300 instruction manual.
Automatic Reset (Auto)
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.

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 set by the user.
A rate sampling relay will activate for the sample time
(sanm t), every time the set point rate is reached.
A total sampling relay will activate for the sample time
(sanm t), every time the process has batched the
amount programmed for the set point (See the
diagrams on page 48 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 after the batch total interval
reaches a certain set point.
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 +5 V
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 steady on) when SW1 & SW2
switches (above) are closed. If the contacts to these
digital inputs are opened, the corresponding front
panel LEDs flash indicating this condition. The
processes being controlled by the interlock relay will
stop, and will re-start only after the interlock relay is
re-activated by the digital inputs (switches).
Note: If multiple digital inputs are assigned to the same
relay, then the corresponding logic is (AND) – i.e. both
switches must be closed to activate the relay.
• If the digital inputs are assigned to the Interlock
Function, then they cannot be used to program
the controller remotely.

Scaling the 4-20 mA Analog Output (Aout)
The 4-20 mA analog output can be scaled to provide
a 4-20 mA signal for any 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.
For further details,
see Setting Numeric Values on page 36.
Reset Menu (reset)
The Reset menu is used to reset the total, grand
totals, batch count, maximum, or minimum reading
(peak or valley) reached by the process; both
maximum and minimum may be reset at the same
time by selecting “reset high & low” (rst HL).
Manual Control Menu (Contrl)
The Manual 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 and to program
the non-resettable totalizer.
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.
Total Password: Prevents resetting the total
manually
Gtotal Password: Prevents resetting the grand total
manually
Protecting or Locking the Controller
Enter the Password menu and program a six-digit
password.
For instructions on how to program numeric values
see Setting Numeric Values, page 36.
Grand Total Reset Password & Non-Resettable Total
The grand total can be password-protected to prevent
unauthorized total resets.
The grand total can be programmed as a
non-resettable total by entering the password
“050873”.
• Once the Grand Total has been programmed as
“non-resettable” the feature CANNOT be
disabled.
Making Changes to a Password Protected Controller
If the controller is password protected, the controller
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 the menu. After exiting the
programming mode, the controller 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 controller is now
unprotected until a new password is entered.
If the correct six-digit password is entered, the
controller displays the message unLoc (unlocked) and
the protection is disabled until a new password is
programmed.
If the password entered is incorrect, the controller
displays the message Locd (Locked) for about two
seconds, and then it returns to Run Mode. To try
again, press Enter while the Locked message is
displayed.
Did you forget the password?
The password may be disabled by entering a
master password once. If you are authorized to

Controller Operation
When installed, the primary way to operate the
controller is with the SafeTouch through-glass buttons
that allow the user to perform various operations
without removing the cover and exposing the
electronics to the hazardous environment. The user
can also operate the controller by connecting a
hazardous area-approved control station or switch to
one of the digital inputs. These can be used to
perform various operations on the controller based on
the Programmable Function Keys. Finally, certain
operations can be performed on the controller with
MeterView Pro software or through Modbus
commands.
The three default operations that can be performed
with the controller’s SafeTouch buttons are:
1. Set the batch size
2. Start the batch
3. Pause/Stop the batch
In addition, the user can program the SafeTouch
Buttons to perform a variety of useful operations by
reassigning them to other functions per Function Keys
& Digital I/O Available Settings on page 64.
Button Operation
The following table shows the default operations for
the F1, F2, and F3 SafeTouch Buttons: setting the
batch size, starting the batch, and stopping the batch.

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
DISABLE) 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 controller.
The symbols by each SafeTouch button correspond
to a mechanical button as shown in the table to the
left.
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.

Manual Batch Control
The manual batch control feature is used for batch
processes where each batch must be started by the
operator. The following diagrams demonstrate a
typical manual batch operation with an optional
hazardous area-approved remote control station. The
batch could also be controlled using the through-glass
buttons on the controller.
Manual Batch Control Operation
1. System Setup
Both valves are closed with an empty barrel
in place. The batched total is displayed in the
main display, the preset is selected for the
second display.
2. Batch Start
The START button is pressed. Both valves
open. The barrel begins to fill.
3. Preclose Valve
When the batch total reaches a value of
50.00 (Preset [55.00] – Pre-close [5.00]) the
full-flow valve closes. The fill rate of the tank
slows as a result.
4. Completed Batch
When the batch is complete, the restricted-flow
valve closes. If overrun occurs, then the next
batch will adjust for this offset amount to
maintain accuracy.
5. Change Preset
After placing a new, empty barrel, a new
preset fill amount may be selected with the
Batch key, while the process is stopped.
6. Begin New Batch
The new batch begins when the START
button is pressed, causing both relays to
activate and both valves to open.

When paused, pressing the START button will
continue the batch, and pressing the STOP button
again will cancel the batch.
STOP Mode
When in STOP mode, the STOP button may be
pressed to cycle through alternative parameters to be
displayed on the second display, including the grand
total, batch count, and preset.
Reset
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.
Automatic Batch Control
The automatic batch control feature is used for batch
processes where the batch size does not change, or
the operator wants the next batch to start
automatically after the previous batch is complete.
The following diagrams demonstrate a typical
automatic batch operation.
Setup for Automatic Batch Control
The batch controller can be configured to
automatically start a new batch after the selected time
delay between batches has elapsed.
The time delay allows time for removing the full barrel
and putting an empty barrel in place. Once the
process starts, the operator does not have to press
any buttons; except to pause or stop the batch
process.

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 Multi-Point Linearization (Linear) on page 62 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.
• 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.
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.
• Note that changing the default programming of
the main or second displays may affect viewing
the batch total (main display) or preset (second
display) of the batch process.
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.
Modbus RTU Serial Communications (serial)
The controller is equipped with serial communications
capability as a standard feature using Modbus RTU
Serial Communication Protocol.
The controller may be connected to a PC for initial
configuration via the on-board USB connection. For
ongoing digital communications with a computer or
other data terminal equipment, use the RS-485
connection with the appropriate serial converter; see
Ordering Information on page 7 for details.
• DO NOT connect any equipment to the RJ45
M-LINK connector. Otherwise damage will occur
to the equipment and the controller.
• DO NOT disconnect the RJ45 connector located
to the left of the power terminal block. Doing so
will disable the on-board digital I/O, and the
RS-485 serial communications.
Notes:
1. More detailed instructions are provided with each
optional serial communications adapter.
2. Refer to the ProtEX-MAX 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.

Select Menu (SElEct)
The Select menu is used to select the signal
conditioner applied to the input (linear), low-flow
cutoff, and analog output programming. The
multi-point linearization is part of the linear function
selection.
Input Signal Conditioning (Functn)
The Function menu is used to select the input signal
conditioner applied to the input: linear. 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.
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.
Low-Flow Cutoff (CutofF)
The low-flow cutoff feature allows the controller to be
programmed so that it always displays zero at very
low flow rates.
The cutoff value may be programmed from 0.1 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
starting 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. Rate)
2. Overrange: Analog output value with display in
overrange condition
3. Underrange: Analog output value with display in
underrange condition
4. Max: Maximum analog output value allowed
regardless of input
5. Min: Minimum analog output value allowed
regardless of input
6. 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.
Analog Output Calibration Procedure
1. Wire the PD8-6310-WM 4-20 mA output to a
current loop that includes a power supply
(internal or external 12 to 24 VDC), and the mA
input on the digital meter. See Figure 27. 4-20

Programmable Function Keys User Menu (user)
• 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.
The User menu allows the user to assign the front
panel function keys F1, F2, and F3, the digital input
F4 (located on the input signal connector), and four
digital inputs (located on the digital I/O connector) to
access most of the menus or to activate certain
functions immediately (e.g. reset max & min, hold
relay states, etc.). This allows the controller to be
greatly customized for use in specialized applications.
The four digital outputs can be assigned to a number
of actions and functions executed by the controller
(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.

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 the Diagnostics menu refer
to page 59.
This menu allows the user to test the functionality of
all the controller LEDs, check the controller’s software
and version information, and erase the MeterView Pro
software installation files from the controller. 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 59.
Testing the Display LEDs
To test all LEDs on the display:
1. Go to the Diagnostics menu (diAG) and
press Enter button.
2. Press Up arrow button and scroll to
LED Test menu (led t).
3. Press the Enter button to activate the LED
Test. The controller will cycle through all
digits, decimal points, and relay indicators to
enable the operator to check that all LEDs
are functioning properly.
4. Press the Enter button again to access the
Information menu (info) or press the Menu
button to return to Run Mode.
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

Troubleshooting Tips
This controller is a highly sophisticated instrument with an extensive list of features and capabilities. If the
programming buttons are used to program the controller, it may be a difficult task to keep everything straight. That is
why we strongly recommend the use of the free MeterView Pro software for all programming activities. The most
recent version of the software is loaded at the factory in the internal controller’s memory. A USB cable is provided for
programming the controller using MeterView Pro software.
If you have programmed the controller with the programming buttons and it is not working as intended, try
re-programming the controller using MeterView Pro software.

Troubleshooting Tips
Symptom
Check/Action
Cannot access main menu
You cannot access the main menu when a batch is running. Make
sure the batch has stopped before trying to access the main menu.
Batch is continuously overfilling
A multi-stage batch with a pre-close amount may be necessary.
See Two-Stage Batch Control Setup Using Relays 1 & 2 on page 54.
Batch is not stopping when preset is reached
Check wiring. Relay 1 corresponds to the preset value.
SafeTouch buttons do not respond
1. If mechanical button was pushed, the SafeTouch buttons
will be re-enabled automatically 60 seconds after the last
button push.
2. If slide switch on connector board is in DISABLE position,
switch to ENABLE.
3. Strong direct sunlight may interfere with SafeTouch button
operation. It is recommended to operate the buttons by
standing so as to block direct sunlight.
Serial Communications METER LINK LED
Indicator is off
Check:
1. Modular cable connection
2. Power to the device
If only the TX (or DATA IN) data status LED is
flashing when serial communications
attempted
Check:
1. Serial cable
2. Instrument address & baud rate
3. Program address & baud rate
If both data status LEDs (TX and RX) are off
when trying to communicate
Remove all unnecessary cables and instruments from the bus.
Try getting the system to work with only one device (to ease
troubleshooting) and then expand the system one device at a
time.
Communications slow
Increase the baud rate
Random communication errors
1. Increase the TX delay time
2. Decrease the baud rate
Other symptoms not described above
Call Technical Support for assistance
Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from factory
defaults and use the manual as a step by step programming guide, rather than a random approach to programming. To reset the
controller to factory defaults, see Reset Controller to Factory Defaults on page 65. In addition, for best results, we recommend using
the free MeterView Pro software for all programming needs.
