INTRODUCTION

The ProVu meter boasts specifications and functionality that clearly makes it one of the most advanced temperature meters available. Its dual-line 6-character display, function keys, and optional expansion modules are only a few of the special features available on the ProVu.


 

Versatile

The PD7000 accepts many more thermocouple types and RTDs than earlier models. It can be configured to have either a 1° or 0.1° display resolution on any type of sensor input. The lower display makes configuration simpler. The display itself is quite configurable. There are many relay functions for up to 8 relays; including an Interlock Relay function. The 4-20 mA output can represent up to 12 different parameters/variables. This makes the PD7000 one of the most versatile meters on the market.


 

FRONT PANEL DISPLAY

Precise, Accurate, and More Informative

ProVu's large 0.6" upper display provides an accurate and precise 4 or 5-digit view of the temperature measurement.


 

Configurable

The upper display can be programmed to indicate current temperature, maximum or minimum temperature, alternating maximum/minimum temperatures, one of eight alarm set points, or Modbus input. The lower display can also be configured to display engineering units, set points, user defined legends, or simply turned off.


 

Function Keys

There are three function keys available to the user. These keys can be programmed to trigger certain events
( i.e. acknowledge alarms, reset max and/or min, disable/enable output relays, or hold current relay states), provide direct menu access points, and more.

Optional SunBright Display Models

ProVu's SunBright display models have an extraordinarily bright LED display. They are perfect for applications where the meter is in direct sunlight or in applications where visibility may be impaired by smoke, fog, dust, or distance. There are 8 user selectable intensity levels to choose from on all ProVu models. This option is available on all ProVu models.


 

Easy to Use

The user friendly dual-line display makes the ProVu easy to set up & program. Input selection and configuration is conveniently set up via rear switches and front panel programming. Three levels of password protection help maintain the reliability of the programming.

Three Tier Password Protection

The ProVu offers 3 levels 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 operator from using the function keys and all meter configuration menus without a password.

Rugged

A unique front panel design makes the ProVu nearly impenetrable in typical applications. Here, the ProVu easily survives a direct hit on the display from a heavy 2" solid stainless steel ball dropped from eight feet.


 

Simplified & Dynamic Menu System

The ProVu minimizes the menu selections by auto-detecting the installed options to determine what menu navigation is required. For example, extra menu items for the relay expansion module, I/O expansion, etc. are not present unless those options have been installed. This is an example of keeping the product simply sophisticated.


 

Max/Min Display

Max/Min (or Peak/Valley) is standard on the ProVu PD7000. Either display can be configured to show either maximum or minimum excursion since last reset. The displays can also be configured to toggle between Max and Min values. Both values can be simply reset from the front panel.


 

Environmentally Protected

The ProVu has standard UV protection, a NEMA 4X front panel, extremely durable face plate, performs in wide ambient operating temperatures, and is CE Certified (high noise and RF immunity).


 

DIGITAL COMMUNICATIONS

Modbus^® RTU Serial Communications

After the purchase of a serial communication adapter for the ProVu meter, any Modbus-ready Master device can communicate with the meter using the ever-popular Modbus communications protocol included in every ProVu. This greatly increases the flexibility of the meter. Modbus provides much more capability than read PV and write set points. Below are some examples of other things that can be done with ProVu's Modbus communications.

• Send a 6-character message to the lower display upon an event
• Convert a digital value to a 4-20 mA signal
• Remote user control (i.e. change set points, acknowledge alarms)
• Input a Modbus digital PV (in place of analog input)
• Remote override of any, or all, relays and analog outputs

Meter Copy

The Copy feature is used to copy (or clone) all the settings from one ProVu to other ProVu meters in about 20 seconds! The Copy function is a standard feature on all meters. It does not require a communications adapter, only an optional cable assembly, P/N PDA1200. See the ordering information for complete details.
 

MULTIPLE SENSOR AVERAGING

The PD7000 can find the average temperature of up to 10 RTD probes connected in parallel. This new calculated value would then be treated as the PV (temperature) displayed on the meter. The average temperature is also available via Modbus communications and as the retransmitted value for the optional 4-20 mA output.


 

METERVIEW^® PRO SOFTWARE

Click here to see the
ProVu videos

ProVu series meter using the PC-based MeterView Pro (MVP) software (serial communications adapter required). MVP makes complete meter configuration simple and fast. Copying one meter configuration to another, as well as saving or retrieving a meter configuration file is a snap. MVP's linearization utility makes even a 32-point linearization task clear and easy to do. We also included a basic meter monitor and data logger for use with a ProVu. Of course, with ProVu's powerful Modbus protocol, custom programs can be made even more versatile. For more details on MeterView Pro, click here.

ProVu VIDEOS

Watch a quick demonstration on how the ProVu works and also how the function keys can simplify functionality. These and other videos are available at here.

FIELD EXPANSION MODULES

Add functionality to the ProVu in the field with easy-to-install external expansion modules. Add RS-232 or RS-422/485 communications, I/O modules (up to 2), and 4-relay expansion module. The menu items for these modules do not appear until the module is connected, simplifying the basic menu. Relay and digital I/O modules are shown below with optional DIN rail mounting kit, P/N PDA1002.


 

PDA1044 I/O Expansion Module

Four digital inputs and four digital outputs are available per expansion module. The ProVu meter will accept two of these modules. External digital inputs can function similarly to the front panel function keys. 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), provide direct menu access point, or mimic front panel keys. The I/O module can be used to configure the ProVu remotely, in essence giving the user control of the four front panel push buttons. This feature is particularly useful if the meter is mounted inside an explosion-proof enclosure.

Digital outputs can be used to remotely monitor ProVu's alarm relay output states, or the states of a variety of actions and functions executed by the meter.



 

PDA1004 Relay Expansion Module

An external module containing four 3 A Form A (SPST) relays can be added to the ProVu at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.



 

PDA1232 & PDA1485 Communication Modules

Serial communications on the ProVu can be added anytime with external PDA1232 (RS-232) or PDA1485 (RS-422/485) communication adapters.

Free Modbus protocol with purchase of ProVu serial communications modules.


 

OUTPUTS

Relay Outputs

The ProVu has up to four 3 A Form C relays (SPDT) with multiple power loss fail-safe options. Relays can be configured for proper protective action upon input loop break. Relay ON and OFF delay times are user adjustable. Up to eight front panel indicators show alarm and/or relay state. All relays can be configured for 0-100% deadband.


 

Relay Operation/Configuration

There are powerful relay functions that can be configured in the ProVu meter, including:

• Automatic reset only (non-latching)
• Automatic + manual reset at any time (non-latching)
• Latching (manual reset only)
• Latching with clear (manual reset only after alarm condition has cleared)
• User selectable fail-safe operation
• Relay action upon sensor break
• Time delay (on and off), independent for each relay
• Manual control mode
• Interlock Relay Mode

Front panel button or digital input may be assigned to acknowledge relays programmed for manual reset.


 

Analog Output

The isolated analog output signal can be configured to represent the measured temperature (including average temperature), maximum or minimum temperature, any of the eight relay set points, manual control setting, 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. A power supply (24 V @ 40 mA) is standard with the 4-20 mA output option.


 

Auto/Manual Control

Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. When the relays and 4-20 mA output are controlled manually, an LED labeled "M" is turned on and the associated Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.

Interlock Relay(s)

This function allows a process to use one or more very low voltage input signals or simple switch contacts to control the state of one or more internal "interlock" relays. A violation (i.e. loss of input, open switch, or open circuit) forces one or more N/O interlock relay contacts to open. One input can be used in series with a number of interlock switches, or up to eight inputs can be required to force-on one (or more) internal interlock relays. Please see Application Note AN-1008 for more information.


Note: Requires PDA1044 Digital I/O module.
