OVERVIEW

The ProtEX-RT PD6830 is a rugged, explosion-proof pulse input rate/ totalizer fully featured for demanding applications in hazardous areas or in the harshest environmental conditions. It is programmed using the four SafeTouch™ through-glass buttons, without removing the cover. The numeric rate display will read up to 99999 and the alphanumeric total/tag display will read up to 9999999. The alphanumeric display can also be programmed to show any combination of numbers and letters up to seven characters long for use as engineering units and/or the process identification tag. The backlight makes the display visible under any lighting condition. The enclosure is provided with threaded conduit holes and integrated pipe or wall mounting slotted flanges.

KEY FEATURES

User Friendly Display

The high contrast 0.7" high 5-digit LCD on the upper display is easy to read. The 0.4" 7-character lower display is alphanumeric and allows for more sensible looking tags, engineering units, or legends than a 7-segment display. For dark areas, the backlight (standard) can be illuminated either via output loop power (BTA & CTB), external 9 to 30 VDC (APO & APA), or battery (BMO).

Through-Glass SafeTouch™ Buttons

The PD6830 is equipped with four sensors that operate as through-glass buttons so that it can be programmed and operated without removing the cover (and exposing the electronics) in a hazardous area. These buttons can be disabled for security by selecting the LOCK setting on the switch located on the connector board in the base of the enclosure. To actuate a button, press one finger to the glass directly over the marked button area. When the cover is removed, four mechanical buttons located next to the sensors are used.

Exceptional Enclosure

Wide Viewing Angle

The copper-free (0.3%), smooth cast aluminum NEMA 4X enclosure is finished with a corrosion resistant epoxy coating. This provides a durable finish, and helps make it an attractive looking enclosure. The built-in mounting flanges are convenient for wall or pipe mounting (up to 2½" pipes). The enclosure is provided with three ¾" NPT threaded conduit holes. The window and display module on the PD6830 enclosure have been optimized to provide a wide viewing angle of approximately +/- 40°, nearly twice the competition! This makes it even easier for operators to see the display.

Environmentally Tough

Alarm Indication

The PD6830 can be configured to have a high or low rate alarm indicator, or a total alarm set point indicator. When in alarm mode, the display will flash, and a HI or LO symbol is displayed. The alarm is acknowledged by pressing the ENTER/ACK button.

Wide Input Signal Selection

The PD6830 is designed to handle a wide variety
of inputs, including: pulse, open collector, NPN,
PNP, TTL, or switch contact. The input can handle
up to a 30 kHz signal without degradation. It can
readily discern inputs with pulse widths as small
as 16 µs. Inputs are conveniently set up on the
display module by simply moving switches to the
desired options.

Gate Function for Slow Pulses

The gate function provides for rate display of slow pulse rates. Using the programmable gate, the meter is able to display pulse rates as slow as 1 pulse every 999 seconds (0.001 Hz). The gate function can also be used to obtain a steady display reading with a fluctuating input signal. There are two settings for the Gate, low gate (

) and high gate (

).

Totalizer Conversion Factor

Total Conversion Factor is used to convert to a different unit of measure for the total display. For example, to display rate in gallons and total in liters, enter a Conversion Factor of 3.7854. When rate and total units are the same, the Conversion Factor should be 1.0000.

Password Protection

A 5-digit password prevents unauthorized changes to the programmed parameter settings. The lock symbol is displayed to show that settings are protected. If the meter is password protected, the meter will display the message LOCKED when the Menu button is pressed.

K-Factor Scaling

The meter may be scaled using the K-Factor function. Most flowmeter manufacturers provide this information with the device. Enter the K-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.

Custom Meter Scaling

In lieu of K-Factor scaling, the meter can be scaled to any span relative to the input pulse rate span (i.e. if you knew the pulse input span for gallons but wanted to display the rate and total in liters). No external signal is required.

Field Calibration with Scaling

In lieu of K-Factor and Meter Scaling, the meter can be calibrated with a precision signal source. While applying a precision signal, the relative scale value is entered via the front panel. This is done at any two points along the scale. Using this method, an operator can set a "best fit straight line" for non-linear input spans.

Alternating Total/Tag Display

The meter can be configured so that the lower display automatically toggles between displaying the assigned tag name and total every 10 seconds.

Design Simplicity

The internal cast rails within the enclosure replace fragile standoffs. They also guide and mount the internal module. Two springloaded thumbscrews make the assembly a snap, while pressing the LCD as close as possible to the glass window to improve wide-angle viewing.

Pulse to 4-20 mA Retransmission

Use the analog output to retransmit the pulse input signal to the commonly used 4-20 mA form. Available on the PD6830's ATA, BTA, and CTB models. Output can be scaled to represent all, or part, of the actual input span. Shown below with switch contact input on a PD6830-APA. See manual for details.

>

Multi-Point Linearizer

The PD6830 has a linearizer which can be
assigned to any two points within the input
function range for best fit. The scale will follow
the linearization slope to the limits of the pulse
frequency input.

PD6830 minimizes linearity error by "best" fitting
a straight line to a non-linear curve.

INSTALLATION

Direct Mounting

The PD6830 is designed to easily mount directly to a flowmeter. The example below shows it mounted to a turbine flowmeter. This particular ProtEX model (BMO) is battery-powered. Even though battery-powered, it does have a backlight; but to conserve battery power, it only turns on while SafeTouch™ buttons are in use.

Installation Flexibility

The PD6830's rotatable display/meter along with three available conduit connections provide for numerous installation options. The display can be rotated in 90° increments. Rotate it 90° for horizontal mounting. Wiring can be routed to the most convenient conduit connection(s). One metal conduit plug is supplied per unit. Additional plugs are available (PDA75PLUG) if needed.

Easy Wiring & Service

It is simple to completely remove the meter module, and set it aside. A heavy duty terminal block is then easily accessed. It is clearly marked to prevent wiring errors. Since the meter module can be removed without breaking the loop, it can be serviced without the need to uninstall the entire product.

FLEXI-POWERED

There are ProtEX-RT models that can be powered by battery, DC with battery back-up, DC only, or the output-loop. Under nominal battery operating conditions, the battery life is approximately 5 years. As an unused back-up, the life is the shelf-life of the battery (up to 20 years). When powering the PD6830-CTB by the output loop, the output load impedance must not exceed 700 O @ 24 VDC excitation (more in specifications).

CONNECTIONS

To access the wiring connections, remove the enclosure cover and unscrew the two captive screws that fasten the display module. Disconnect the ribbon cable and remove the display module. Power and signal connections are made to a terminal block at the base of the enclosure. Grounding connections are made to the two ground screws provided on the base — one internal and one external.
