Yokogawa YPP6300 - Dual Line 6 Digit Pulse Input Flow Rate Totalizer

PERFECT FOR FLOW APPLICATIONS

The YPP6200 and YPP6300 PROPLUS meters are 1/8 DIN flow rate/ totalizers specifically designed for displaying flow rate and total from flowmeters with analog or pulse outputs. These flow rate/totalizers are particularly well-suited for flow applications because they can display flow rate and flow total at the same time, provide power to drive the flowmeter, and display flow total, flow grand total, or non-resettable flow total on up to nine digits.

Front Panel Display - Display Flow Rate, total or Grand total

The upper display can be programmed to display flow rate, total, or grand total, and the lower display can be programmed to display flow rate, total, grand total, engineering units, custom legends, or can be turned off. Both displays could also display relay set points, or max and min values.

In the graphic at the top of the page, the upper display is displaying flow rate (as indicated by the “R” to the right of the number) and the lower display is displaying flow grand total (as indicated by the “G” & “T” under the number.) The following photographs show typical ways these flow rate/totalizers can be programmed.

Optional SunBright Display Models

PROPLUS’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. Option is available on all PROPLUS models.

Totalizer Overflow Displays Total to 9 Digits

These flow rate/totalizers can display up to nine digits of total flow with the total overflow feature. In the diagrams below, the flow totalizer is displaying 532,831,470 by toggling between a display of “oF 532” and “831470”. Notice the (T with arrow ▲ symbol) is lit up indicating the display is in overflow mode.

Rugged

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

Three Tier Password Protection

The PROPLUS 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.

Easy to Use

The user friendly dual-line display makes the PROPLUS easy to set up & program. No jumpers to set for input selection. All setup & programming are done via the front panel.

Simplified & Dynamic Menu System

The PROPLUS 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.

On-Board Digital Input

The YPP6200 and YPP6300 include a digital input 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.

TOTALIZER CAPABILITIES

PROPLUS flow rate/totalizers can be programmed for a wide variety of totalizer applications. They can display total, grand total, or non- resettable grand total with a time base of seconds, minutes, hours or days. The user can program a totalizer conversion factor, a non- resettable grand total, password protection, and several total reset methods.

Totalizer Conversion Factor

The user can enter a totalizer conversion factor that allows the meter to display total in different units than the rate. For instance, a customer could measure flow rate in gallons per minute and total in hundredths of acre-feet.

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.

Totalizer Password Protection

The total and grand total can be password protected so they can be reset only by authorized personnel.

Remote Total Reset

An I/O expansion module can be used to remotely reset the total or grand total. The reset switch is wired into the module and the module is connected to the M-Link RJ45 connector at the back of the flow rate/totalizer.

Total Alarms

The PROPLUS’s four internal and four external relays can be set up to alarm when the total reaches a user-defined set point. A variety of reset modes are available and the user can also program time delays and fail-safe operation.

Front Panel Total Reset

The three front panel function keys can be programmed to reset the total and grand total.This makes it possible for the user to reset either the total or the grand total by pressing the appropriate function key. Of course, if the total or grand total is password protected, they will not reset when the function key is pressed.

Modbus® RTU Serial Communications

With the purchase of a serial communication adapter, PROPLUS meters can communicate with any Modbus Master device using the ever-popular Modbus communications protocol that is included in every PROPLUS. 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 PROPLUS’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 PROPLUS to other PROPLUS 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 YPPA1200. See the ordering information for complete details.

PROPLUS SOFTWARE

Configure, monitor, and datalog a PROPLUS YPP6200/YPP6300 from a PC using PROPLUS Software and a serial adapter.

Field Expansion Modules

Add functionality to the PROPLUS 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 YPPA1002.
 

YPPA1044 I/O Expansion Module

Four digital inputs and four digital outputs are available per expansion module. The PROPLUS 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 PROPLUS 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 PROPLUS’s alarm relay output states, or the states of a variety of actions and functions executed by the meter.

YPPA1004 Relay Expansion Module

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

YPPA1232 & YPPA1485 Communication Modules

Serial communications on the PROPLUS can be added anytime with external YPPA1232 (RS-232) or YPPA1485 (RS-422/485) communication adapters.

Relay Outputs

The PROPLUS 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 PROPLUS 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)
• Pump alternation control (automatic reset only)
• Sampling (activated for a user-specified time)
• User selectable fail-safe operation
• Relay action for loss (break) of 4-20 mA input signal
• Time delay (on and off), independent for each relay
• Manual control mode
• Interlock relay mode

Analog Output

The isolated analog retransmission signal can be configured to represent the rate/process variable (PV), 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.

Manual Output 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.

Isolated Transmitter Power Supplies

A powerful 24 V @ 200 mA power supply is a standard feature on the PROPLUS 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 set point for a “sampling” relay. When the process (rate or total) reaches that set point, 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 wastewater sampling. When the wastewater total reaches a preset total interval (i.e. every 10,000 gallons), the relay contacts would close for a preset time, and by some means (light, horn, etc.) alert someone to take a sample, or provide the trigger to automatically take a sample of the wastewater (see chart on page 5). 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 rate or a total interval reaches a certain set point.

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 on our website for more information. Requires YPPA1044 Digital I/O module.

Differential Pressure Flow

The YPP6200 can display flow rate and total by extracting the square root from the 4-20 mA signal from a differential pressure transmitter. The user selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user selectable value.

• Display Flow Rate
• User Selectable Low-Flow Cutoff
• Only 2 Calibration Points Required

Convert Pulse to 4-20 mA with YPP6300

The YPP6300 accepts the pulse output from a flowmeter and with the appropriate option installed can convert the pulse to a 4-20 mA signal. The 4-20 mA signal can be programmed to correspond to either the flow rate or the total flow.

• Use K-Factor or Multi-Point Scaling
• PROPLUS Powers the Flowmeter
• Display Flow Rate & Total

Open Channel Flow

The YPP6200, in combination with an ultrasonic level transmitter, makes for an economical way to measure and display open channel flow rate and total in most weirs and flumes and take periodic samples. All the user needs to do is enter the exponent for the weir or flume into the YPP6200 and the YPP6200 automatically raises the input signal to that power. Sampling can be based on the total flow or the flow rate. For instance, to display open channel flow rate and total from a 3 inch Parshall flume and take a one pint sample every 100,000 gallons, the user would program the YPP6200 as follows:
