weighing and measuring devices. These easy-to-use batch controllers are ideal for weights and
measures applications, and provide simple independent batch control operation where local
control is preferred to expensive and expansive operation systems.
digits make it easily readable in smoke, dust, fog, and, with the optional SunBright® display,
even direct sunlight.
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 front panel start, pause, stop, and batch size
(preset) changes. The bottom display can be programmed to display rate, grand total, batch
count, or preset by cycling the Stop (F3) button. A digital input is standard.
Single and multi-stage batching is possible with up to 4 on-board relays and 4 with the external
relay module. 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 10% of the programmed preset
value.
At least two SPDT relays are included for use in batch control or rate alarms.
The batch controllers also share all common P
transmitter power supply and Modbus RTU Serial communications.

Installation
There is no need to remove the controller from its case to complete the installation, wiring, and
setup of the controller for most applications. Instructions are provided for changing the transmitter
power supply to output 5 or 10 VDC instead of 24 VDC, see page 13.
Hazardous voltages exist within enclosure.
Installation and service should be performed only by
trained service personnel.
g!
WARNING: Risk of electric
shock or personal injury.
Unpacking
Remove the controller from box. Inspect the packaging and contents for damage. Report
damages, if any, to the carrier.
If any part is missing or the controller malfunctions, please contact your supplier or the factory for
assistance.
1. Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x 45 mm). Refer to Figure 1
for more details.
2. Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.
3. Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
4. Remove the mounting bracket mounted on the controller (back-off the screw so that there is ¼"
(6.4 mm) or less through the bracket. Slide the bracket toward the front of the case and remove).
Note what side this bracket is mounted to.
5. Locate the security bracket packed in the wire security seal kit. The security bracket can be
identified by wire loop pass-through located next to the mounting screw.
6. Insert controller into the panel cutout.
7. Mount each bracket. Be sure the security bracket is located on the side of the case with the wire
loop pass-through holes.
8. Tighten the screws against the panel. To achieve a proper seal, tighten the mounting bracket
screws evenly until
controller is snug to the panel along its short side. DO NOT OVER
TIGHTEN, as the rear of the panel may be damaged.
All controllers, including models equipped with the 12-24 VDC power option, are shipped from the factory
configured to provide 24 VDC power for the transmitter or sensor.
If the transmitter requires 5 or 10 VDC excitation, the internal jumper J4 must be configured accordingly.
To access the voltage selection jumper:
1. Remove all the connectors.
2. Unscrew the back cover.
3. Slide the back cover about 1 inch.
4. Configure the J4 jumper, located behind the input signal connector, for the desired excitation voltage
as shown.
All controllers include a programming lockout jumper. With this jumper installed, the controller will not
allow access to the programming menus. If the Menu button is pressed, the controller will display Locked
Seal (LoCd SEAL). The controller will still allow all batch controller operations to function, such as the
START, BATCH, and STOP buttons.
Complete Setup Before Installing Lockout Jumper
Set up the controller with all necessary settings prior to
installing the lockout jumper.
Installing the programming lockout jumper will prevent access
to the programming menus.
The jumper may be removed to regain access to the programming menus.
Combined with sealing the rear case to restrict access to the programming lockout jumper, the controller
meets the requirements for National Conference on Weights and Measures (NCWM) National Type
Evaluation Program (NTEP) certification.
To secure the programming lockout jumper with a wire security seal, refer to Wire Security Seal Installation (NTEP Seal), see page 15.
To access and enable the programming lockout jumper:
1. Remove all the connectors.
2. Unscrew the back cover.
3. Slide the back cover about 1 inch.
4. Configure the JP1 jumper, located behind the input signal connector, for the desired programming
lockout operation (lockout on or off) as shown.
All controllers include mechanical features to install a wire security seal. This seal secures the rear case
portion of the controller, preventing unauthorized access to the programming lockout jumper.
Combined with using the programming lockout jumper to restrict access to the programming, the controller meets the requirements for National Conference on Weights and Measures (NCWM) National Type
Evaluation Program (NTEP) certification.
To enable the programming lockout jumper, refer to Programming Lockout Jumper (NTEP Lockout), see
page 14.
Note: Installation instructions for PD8-6310-WM Explosion Proof model differ from what is described
below. Due to the lack of a mounting bracket, there is an additional wire loop pass-through hole in
the front portion of the controller housing. See Security Seal Installation Guide included with your
controller.
To install the wire security seal:
1. Locate the wire security seal and security seal mounting
bracket packed with the controller. Install the panel meter
as described in Panel Mounting Instructions on page 12.
Be sure the security seal mounting bracket is located on
the side of the case with the wire loop pass-through holes.
This bracket can be identified by wire loop pass-through
located next to the mounting screw.
2. Pass the wire security loop through the wire loop
pass-through holes on the rear portion of the
controller housing.
3. Pass the wire loop through the wire
loop pass-through holes on the security bracket. The pass-through is located next to the mounting screw.
4. With the wire loop through the rear of the
case and the mounting bracket, pass the
loop back through the crimp seal end.
Tighten the loop such that it will prevent
the rear of the case from being removed
while the loop is in place.
5. The wire loop may now be tagged,
crimped, and sealed to mechanically
secure the rear case. This will secure the
programming lockout jumper.
All connections are made to removable screw terminal connectors located at the rear of the controller.
Use copper wire with 60°C or 60/75°C insulation for all
line voltage connections. Observe all safety regulations.
Electrical wiring should be performed in accordance with
all applicable national, state, and local codes to prevent

Relay Connections
Relay connections are made to two six-terminal connectors labeled RELAY1 – RELAY4 on Figure 7.
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.
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:

Analog Output Transmitter Power Supply
The internal 24 VDC power supply powering the analog output may be used to power other devices, if the
analog output is not used. The I+ terminal is the +24 V and the R terminal is the return.
External Relay & Digital I/O Connections
The relay and the digital I/O expansion modules PDA1004 & PDA1044 are connected to the controller
using a CAT5 cable provided with each module. The two RJ45 connectors on the expansion modules are
identical and interchangeable; they are used to connect additional modules to the system.
Note: The jumper located between the RJ45 connectors of the PDA1044 must be removed on the second
digital I/O module in order for the system to recognize it as module #2.
Do not connect or disconnect the expansion
modules with the power on!
Warning!
More detailed instructions are provided with each
optional expansion module.
As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as
interlock relay(s). Interlock contact(s) are wired to digital input(s) and trigger the interlock relay. This
feature is enabled by configuring the relay, and relative digital input(s) (see page 40). In one example, dry
interlock contacts are connected in series to one digital input which will be used to force on (energize) the
assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front
panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O
contact). See below.
The controller has been factory calibrated to read input
frequency in Hz (pulses/sec). The calibration equipment is
certified to NIST standards.
Overview
Most setup and programming is done through the front panel buttons.
The PD6310 has one switch located to the right of the input connector, which must be configured
according to the input level and type. Jumper J4 located inside the controller, 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.
After power and input signal connections have been completed and
verified, apply power to the controller.

Press the Right arrow button to move to the next digit during digit or decimal point programming.
Press or hold the Up arrow button to scroll through the menus,
decimal point or press or hold to increment the value of a digit.
Press the Enter button to access a menu or to accept a setting.
Press and hold the Menu button for three seconds to access the advanced features of the controller.
The controller accepts pulses (e.g. ±40mV to ± 8V), square wave (0-5, 0-12V, or 0-24V), open collector
NPN, PNP, TTL, or switch contact signals.
These signals are scaled to represent rate in engineering units from -99999 to 999999. The pulse
signals may be scaled with a K-factor to represent a total for the batch, and grand total.
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 (and 4 available with an external expansion module) 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.
Default Batch Control Operation
The following describes the operation of the three front panel operating keys as programmed with default
settings.
START Button
Press the START button to begin a new batch process.
BATCH Button
Press the Batch button to access the Preset (batch amount) menu. Program the batch with the arrow
keys, and confirm with the Enter key.
STOP Button
Press the STOP key once during a batch to pause. Press the STOP key while paused to stop and
cancel the batch. Press the STOP key while in stop/ready mode cycle lower display values of rate (or
other lower display programmed parameter), grand total, batch count, and preset.
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.
The following example shows how two stage batch control functions. 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.

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 the upper display 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. The lower window 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.
Press Enter to enter the relay assignment parameters.

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 certified 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)
There is a switch, located to the right of the input connector, which must be configured according to the
input level and type. Jumper J4 located inside the controller, behind the input signal connector, is used to
select the excitation voltage (24 V*, 10 V or 5 V) which is supplied to the P+ and P- wiring terminals.
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.
*Default setting
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 line 2 parameter. See the flow chart on page 35
to access the display menu to show the unit or tag on line 2. The engineering units or custom legends can
be set using the following 7-segment character set:

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.
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 controller has been factory calibrated to read input frequency in Hz (pulses/sec). The calibration
equipment is certified to NIST standards.
Use the K-Factor menu to match the rate/totalizer with a flowmeter’s k-factor (pulse/unit of measure).
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. Enter K-Factor
2. Scale without a signal source
3. Calibrate with a calibrated signal source
4. Total time base & conversion factor
5. Grand total time base & conversion factor
6. 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 on page 46.
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.
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 50 for details.
K-Factor Calibration (Factor)
The meter 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 meter will automatically calculate
the flow rate using the k-factor and the time base selected.
The pulse inputs can be scaled to display the input frequency process variable as engineering units.
A signal source is not needed to scale the controller; simply program the inputs and corresponding
display values.
For instructions on how to program numeric
values see Setting Numeric Values, page 28.
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 13.2 gal/min, this must be converted to gal/sec. In this scenario,
the numbers input into the SCALE menu would be as follows:
Set the time base set to minutes (see below) and the meter will display 13.2 gal/min at
1000 Hz
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.
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, m
3
, 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 ten per second and the total conversion factor was
100, the total would increase by 1000 every second. This is useful, for instance, if you want to show rate
in gallons and total in thousands of gallons.
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 22. 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 45 for details.
Calibrating the Controller with External Source (Cal)
To scale the controller without a signal source, refer to Scaling
the Controller (SCALE) page 32.
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.
Note: The display values (DiS 1 and DiS 2) need to be in units of measure per second.

and they will remain in the state found prior to
entering the Relay menu.
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
Assign preclose
if multiple relays
are assigned.
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.
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.
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 and/or 4 external
relays expansion module.
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 23.
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.
Fail-Safe
Selection
Off Open Closed Closed Open
On ClosedOpen Open Closed
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.

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. F
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).
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
The following graphs illustrate the common operation of the relays, status LEDs, and ACK button.
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.
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.
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).
Control Menu (Contrl)
The Control menu is used to control the 4-20 mA analog output and the relays manually, ignoring the
input. Each relay and analog output can be programmed independently for manual control. Selecting
automatic control sets all relays and analog output for automatic operation.
Setting Up the Password (pass)
The Password menu is used for programming three levels of security to prevent unauthorized changes to
the programmed parameter settings 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 28.
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”.
!
Caution!
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
make changes, enter the master password
508655 to unlock the controller.
In addition to the functions described in Controller Operation on page 22, the following advanced
operation and display features may be programmed. Configuring these features may disable some
default batch controller features, or make running a batch operation impossible. These functions should
only be used by users who are sure of their need in their application.
Advanced Features Menu
To simplify the setup process, functions not needed for most applications are located in the Advanced
Features menu.
Press and hold the Menu button for three seconds to access the advanced features of the controller. This
cannot be done during a back process as all functions other than STOP are disabled during a batch
process, including the Menu button.

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.
Only STOP Operation Enabled if a Batch is Running.
During a batch process, the only function that can be
performed is the 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.
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 AdvancedFeatures menu. Up to 32 linearization points may be
selected. See page 50 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.
Note that changing default the
programming of line 1 or line 2
!
will interfere with seeing the
batch total (line 1) or rate (line 2)
of the batch process.
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.
Note: The filter for a PD6310 works differently. There are two available settings: Hi Speed and Lo Speed
(programmable from 2 to 50).
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 6 for details.
Do not connect any equipment other than Precision Digital’s
expansion modules, cables, or controllers to the RJ45 M-LINK
Warning!
connector. Otherwise damage will occur to the equipment
and the controller.
Note: Changes made to the Serial menu are initialized after the MENU key is pressed or after
navigating
through the remainder of the serial parameters (i.e. pass the t-byte parameter).
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.
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 number of points used in the linear conditioning function applied
to the input.
Controllers are set up at the factory for linear function with 2-point linearization.
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.
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.
The multi-point linearization can be used to linearize the
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.
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. 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.
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
(a digital input located on the signal input connector), and up to eight additional digital inputs to access
most of the menus or to activate certain functions immediately (e.g. reset max & min, hold relay states,
etc.). This allows the meter to be greatly customized for use in specialized applications.
Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter
(i.e. alarms, relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital
outputs can be used to trigger external alarms or lights to indicate these specific events.

The rugged design and the user-friendly interface of the controller should make it unusual for the installer
or operator to refer to this section of the manual. However, due to the many features and functions of the
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 46.
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
46.
