PD8-6210 / PD8-6310 ProtEX-MAXTM Batch Controllers
INTUITIVE BATCH CONTROL
The front panel has intuitive buttons and displays that make
operating the batch controller clear and easy right out of the box.
START,BATCH, and STOPbuttons comesetup bydefaultfor batch
controller operation. The START button is used to begin a batching
process. The BATCH button is used to quickly access the preset
value. The STOP button can be pressed once to pause a batch, or
twice to cancel a batch in progress. The upper and lower displays
can be easily configured for your application need. The STOP
button may be used to easily cycle the lower display information
while the batch is stopped.
Easily Choose Your Display Information
Batch Total & Preset
The preset on the lower display
provides even quicker access to the
preset menu just by using the arrow
keys to change the value.
Batch Total & Rate
The rate on the lower display may
be alternated with units for variable
flow batching systems. Rate alarms
may also be used during the batch
process.
Batch Total & Batch Count
The batch count on the lower
display, tracks completed batches.
The count may be set back to 0
with the reset menu.
Batch Total & Grand Total
A grand total with overflow digits
for up to a 9 digit total may be
displayed in the lower display,
with password protection and non-
resettable programmable features.
Clearly Labeled Displays
The upper display alternates the display to show the controller state
when in pause or stop mode. When displaying rate, grand total,
batch count, or preset, the lower display alternates between the
display value and the function or unit of measure.
Alternating DisplayBatch Total & Preset
Grand Total Displays Up to 9 Digits
These batch controllers can display up to nine digits of total flow
with the grand total feature. In the diagrams below, the batch
controller is displaying 532,831,470 by toggling between a display
of “oF 532” and “831470”. Notice the (GT with arrow ▲ symbol) is lit

PD8-6210 / PD8-6310 ProtEX-MAXTM Batch Controllers
BATCH CONTROLLER CAPABILITIES
AProtEX-MAXbatchcontrollercanbeprogrammedforawidevariety
of applications. Setup is easy for single or multi-stage batching.
Automatic overrun correction keeps the batch size accurate, even
over time and with system wear. It can record grand total, or non-
resettable grand total with a time base of seconds, minutes, hours
or days. The user can program a conversion factor, and configure a
non-resettable grand total, and 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 not automatically restart. The START button or digital input
must be used.
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,
withadditionalrelaysbeyondthefirstincludingapreclosevalue.The
preclose deactivates the relay before the batch is finished, to allow
slower fill rates and a more accurate batch finish. With expansion
module relays, up to eight-stage batching is possible. Each
additional stage batching relay has an individually programmable
preclose amount.
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 hundredths of acre-feet.
Grand Total & Rate Alarms
The ProtEX-MAX’s four internal and four external 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.
On-Board Digital Input
The PD8-6210 andPD8-6310 include a digitalinput as standard.This
digital input can operate with the tare, reset tare, or interlock relays
feature, force relays on from a signal from a PLC or relay on other
equipment, and much more. This is ideal for installations where the
meter is inaccessible behind a cover, or where an additional function
key is needed for customized operation.
Rounding
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 a input of
12346, the display would indicate 12350.
COMMON PROTEX-MAX FEATURES
SafeTouch®Button Programming
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 hazardousarea. TheSafeTouch
buttons are configured by default to duplicate the function of the
front panel mechanical pushbuttons associated with the integrated
meter.
Standard SunBright LED Display
The ProtEX-MAX’s SunBright display features extraordinarily bright
LEDs. They are perfect for indoor and outdoor applications where
visibility may be impaired by smoke, fog, dust, or distance or even
in direct sunlight.
Free USB Programming Software & Cable
The ProtEX-MAXTM 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. The software will allow you to configure,
monitor, and datalog a ProtEX-MAXTM PD8-6210/6310 using your
PC. Just simply connect the meter to your PC with the USB cable
and within minutes you will be programming it.

PD8-6210 / PD8-6310 ProtEX-MAXTM Batch Controllers
DIGITAL COMMUNICATIONS
Modbus®RTU Serial Communications
With the purchase of a serial communication adapter, ProtEX-MAX
controllers can communicate with any Modbus Master device using
the ever-popular Modbus communications protocol that is included
in every ProtEX-MAX. Below are some examples of other things
that can be done with ProtEX-MAX’s Modbus communications.
• Start, pause, stop, or change preset values
• Send a 6-character message to the lower display upon an event
• Remote user control (i.e. change set points, acknowledge alarms)
• Read rate, total, grand total, batch count, etc.
OUTPUTS
Relay Outputs
The ProtEX-MAX has up to four 3 A Form C relays (SPDT) with
multiple programmable functions. One (relay 1) should always be
used for batch control. Other relays may be configured as additional
batch relays, with or without preclose for multi-stage batching or as
alarms for the rate or grand total. Each alarm has multiple power
loss fail-safe options. Alarm relays can be configured for proper
protective action upon input loop break. Alarm relay ON and OFF
delay times are user adjustable. Up to eight front panel indicators
show alarm and/or relay state. All alarm relays can be configured
for 0-100% deadband. Rate alarms are only active while a batch is
running.
RelayOperation/Conguration
There are powerful relay functions that can be configured in the
ProtEX-MAX controller, including:
• Single and multiple stage batch control with preclose
• Manual and automatic batch control modes
• Rate alarms during batch process
• Grand total alarms
• Sampling function
• User selectable fail-safe operation
• Relay action for loss (break) of 4-20 mA input signal (PD8-6210)
• Time delay (on and off), independent for each alarm relay
Analog Output
The isolated analog retransmission signal can be configured
to represent the batch total, grand total, maximum (peak) value,
minimum (valley) value, the value for any of the eight relay set
points, manual setting control, or Modbus input. While the output is
nominally 4-20 mA, the signal will accurately accommodate under-
and over-ranges from 1 to 23 mA.
Isolated Transmitter Power Supplies
A powerful 24 V @ 200 mA power supply is a standard feature on
the ProtEX-MAX controller. It can be configured for 5, 10, or 24 V
(default) by means of a simple internal jumper (see manual). An
additional power supply (24 V @ 40 mA) is standard with the 4-20
mA output option.
Remote MessageModbus PV Input
INTEGRATED DIGITAL I/O AND SERIAL
COMMUNICATIONS
Digital I/O Connections
Four digital inputs and four digital outputs come standard with the
ProtEX-MAX. External digital inputs can function similarly to the
front panel function keys or digital input F4. They can be configured
to trigger certain events (i.e. acknowledge/reset alarms, reset max
and/or min values, disable/enable all output relays, and hold current
relay states), or provide a direct menu access point. The inputs can
be used to configure the meter remotely using panel mount push
buttons on a control station, giving the user remote control of the
four front panel push buttons.
Digital outputs can be used to remotely monitor the ProtEX-MAX’s
alarm relay output states, or the states of a variety of actions and
functions executed by the meter.
Note: The onboard digital inputs (1-4) are configured at the factory to function
identically to the front panel pushbuttons (Menu, F1, F2, & F3) in order to work with
the SafeTouch buttons. Changing the programming of the digital inputs will affect the
function of the SafeTouch buttons.
Serial Communications Connections
ProtEX-MAX meters come with an RS-485 connection for serial
communications with other digital devices. The industry standard
Modbus®RTU protocol is included with every meter.
RS-485 Connectors
Digital I/O Connectors
Four Types of Password Protection
The ProtEX-MAX offers 4 types of password protection. Level 1
protection allows the operator use of only the 3 pre-configured
function keys on the front panel without a password. Level
2 protection allows the operator use of only the function keys
and the ability to change set points without a password. Level 3
protection restricts the function keys and all configuration menus
without a password. Grand total reset protection prevents the
total from beingreset manually.
Rugged
A unique front panel design makes the ProtEX-MAX nearly
impenetrable in typical applications. Here, the ProtEX-MAX easily
survives a direct hit on the display from a heavy 2"solid stainless
steel ball dropped from eight feet.

PD8-6210 / PD8-6310 ProtEX-MAXTM Batch Controllers
MANUAL MULTI-STAGE BATCH CONTROL OPERATION
System Setup
Both valves are closed with an empty barrel
in place. The batched total is displayed in the
upper display, the preset is selected for the lower
display.
Batch Start
The START button is pressed. Both valves open.
The barrel begins to fill.
Preclose Valve
When the batch total reaches a value of 50.00
(Preset [55.00] – Preclose [5.00]) the full-flow
valve closes. The fill rate of the tank slows as a
result.
Completed Batch
When the batch total equals the preset amount,
the restricted-flow valve closes. The barrel is now
full. If some overrun occurs, the next batch will
adjustfor this offsetamount tomaintain accuracy.
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.
Begin New Batch
Press the START key and a new batch will begin.
With both valves open, the process continues.
Pause/Stop
At any time, the STOP button may be pressed,
once to Pause the process, or twice to cancel the
batch, which stops the process.

update for fast pulse rates while displaying slow pulse rates, if needed. For example: If the low gate
is set to 1.0 second and the high gate to 999.9 second, with a fast pulse rate the display is updated
every second; with a slow pulse rate the controller is capable of waiting up to 999.9 seconds before
calculating the rate, making it possible to display a very slow rate down to 1 pulse/999.9 second
(0.001 pulse/second).

2. Manual reset only, when batch is stopped (latching).
3. Manual reset only after alarm condition has cleared (latching)
Note: Front panel button or digital input may be assigned to acknowledge relays programmed for
manual reset. This replaces one of the standard batch control function keys. Only the PAUSE/STOP
key function is possible during a batch process, so manual reset may only be done when the
controller is in STOP mode.
Deadband: 0-100% of span, user programmable
Time Delay: 0 to 999.9 seconds, on & off relay time delays. Programmable
and independent for each relay.
Fail-Safe Operation: Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.
Auto Initialization: When power is applied, relays will reflect the state of
the input. Alarms are active only when the batch is running.
