 Feature Rich and FlexibleThe ProVu digital panel meter boasts specifications and functionality that clearly make it one of the most advanced process meters available. Its dual-line 6-digit display (999,999), advanced math functions, function keys, Modbus RTU serial communications, and optional expansion modules are only a few of the features found on the ProVu PD6000.FRONT PANEL DISPLAYPrecise, Accurate, and More InformativeProVu's large 0.6" main display provides a highly accurate and precise 6-digit view of your process. Its 24-bit A/D is accurate to ± 0.03% of calibrated span ±1 count.   Easy to UseThe user friendly dual-line display makes the ProVu easy to set up & program. No jumpers to set for input selection. All setup & programming is done via the front panel. Three levels of password protection help maintain the reliability of the programming.ConfigurableThe main display can be programmed to indicate PV, maximum (peak), minimum (valley), alternating maximum/minimum, or one of eight alarm set points. The secondary display can also be configured to display engineering units, setpoints, user defined legends, or simply turned off. SunBright Display ModelsProVu'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, or dust. There are 8 user selectable intensity levels to choose from.
Three Tier Password ProtectionThe ProVu offers 3 levels of password protection:
Advanced Linearization CapabilityThe ProVu includes a 32-point linearizer. In non-linear level applications (i.e. some pumping or lift stations), it can easily compensate for submerged equipment or plumbing that displace usable volume. A second independent 8-point linearizer is available for a second scaled display (PV2) when "Level" function is enabled. Precision Digital's free MeterView Pro PC-based software greatly simplifies the construction of the linearization tables. The software can save this data to the meter and/or PC.Simplified & Dynamic Menuing SystemThe ProVu minimizes the menu selections by auto-detecting the installed options to determine what menu navigation is required. For example, you won't have extra menu items for the relay expansion module, serial communications module, I/O expansion, etc. unless those options have been installed. This is an example of keeping the product simply sophisticated.Max/Min DisplayMax/Min (or Peak/Valley) is standard on the ProVu PD6000. 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 ProtectedThe 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 COMMUNICATIONSModbus® RTU Serial CommunicationsWith the purchase of a serial communication adapter, any Modbus Master device can communicate with the PROVU using the everpopular Modbus communications protocol (included in every PROVU). This greatly increases the flexibility of the meter. The user can do a lot more than read PV and write setpoints with Modbus communications. Below are some examples of other things you can do with PROVU's Modbus communications.
FIELD EXPANSION MODULESAdd 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), or 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 ModuleFour digital inputs and four digital outputs are available per expansion module. The ProVu digital panel 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. 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.
Meter CopyThe 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. MULTI-PUMP ALTERNATIONFor pump control applications where 2 or more similar pumps are used to control the level of a tank or a well, it is desirable to have the pumps operate alternately; this prevents excessive wear and overheating of one pump over the lack of use of the others. The ProVu can accommodate up to 8 pumps. In the example below, a pair of relays have been set up to alternate every time an on/off pump cycle is completed. Another pair of relays is used for low and high alarms. Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.  With the Pump Alternation feature activated, the next time the level reaches 6000 gallons, relay #3 transfers and starts the backup pump.  If the backup pump is not able to keep up, and the level reaches 7000 gallons, relay #4 transfers and starts the main pump as well.  Relay #2 trips the High Level Alarm at 7500 gallons and resets at 6900 gallons.  Relay #1 trips the Low Level Alarm at 495 gallons and resets at 750 gallons. MATH FUNCTIONSNon-Linear input signals (i.e. weirs & flumes, differential pressure, etc.) can be linearized with the ProVu's simple to use built-in math functions, such as: square-root extractor, exponential linearizer, horizontal round tank linearizer, or the ProVu's powerful general purpose 32-point linearizer.

OUTPUTSRelay Outputs
Relay Operation/ConfigurationThere are powerful relay functions that can be configured in the ProVu meter, including:
Analog OutputThe isolated analog retransmission signal can be configured to represent the process variable (PV), maximum (peak) value, minimum (valley) value, or the value for any of the eight relay set points. While the output is nominally 4-20 mA, the signal will accurately accommodate under- and over-ranges from 1 to 23 mA. Auto/Manual ControlTake 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 Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.Isolated Transmitter Power SuppliesA powerful 24 V @ 200 mA power supply is a standard feature on the ProVu meter. 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.Sampling Function (PV triggered timed relay)The sampling function allows the operator to set a setpoint for a "sampling" relay. When the PV reaches that setpoint, it will close that relay's contacts for a preset period of time (0.1 to 5999.9 seconds). An example of its use may be for beer/ale fermentation. When the batch reaches a certain pH, the relay contacts would close and by some means (light, horn, etc.) alert someone to take a sample, or provide the trigger to automatically take a sample of the batch. 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 PV reaches a certain setpoint. Interlock Relay(s)This feature allows a process to use a very low voltage input signal(s) or simple switch contact(s) to force closed N/O contacts of assigned internal relay(s) to "open" when an external switch contact (or any part of the circuit) is opened. 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-1007 on our website for more information. Requires PDA1044 Digital I/O module.
