FREE MeterView Pro
Programming Software
The controller can be powered from the Micro USB connection.
When using the Micro USB connection, DO NOT apply AC or DC
power to the controller.
The easiest and quickest way to program your PROVU
batch controller is to use the FREE MeterView Pro
programming software. This software 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 PROVUto 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 front
panel buttons and the instructions in this manual to do
so.

PROVU™PD6310-WM NTEP Certified Pulse Input Batch Controller
Instruction Manual

Introduction
The PROVUPD6310-WM Series are NTEP®Certified
pulse input batch controllers certified as 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. Their
SunBright LED digits make it easily readable in
smoke, dust, fog, and 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. Display line 2 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
four (4) on-board relays and four (4) external relays
with the external relay module. Each pre-close relay
may have a unique pre-close 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.
At least two SPDT relays are included for use in batch
control or rate alarms.
The batch controller also shares all common PROVU
Series features, including an isolated 24 VDC
transmitter power supply and Modbus RTU Serial
communications.

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 22. 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 23. 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.
F4 Digital Input Connections
A digital input, F4, is standard on the controller. This
digital input should be connected with a normally
open contact across F4 and COM, or with an active
low signal applied to F4. It can be used to start/stop
the batch, reset the total, acknowledge/reset relays,
or to reset max/min values. See Function Keys &
Digital I/O Available Settings on page 51 for a
complete list of capabilities.
