PD6830 Pulse Input Rate/Totalizer Instruction Manual

INTRODUCTION

The ProtEX-RTP 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 more visible under any lighting

condition. The enclosure is provided with threaded conduit holes and integrated pipe

or wall mounting slotted flanges.

SAFETY INFORMATION

WARNINGS

 Read complete instructions prior to installation and operation of the meter.

 Installation and service should be performed only by trained service

personnel. Service requiring replacement of internal components must be

performed at the factory.

 Disconnect from supply before opening enclosure. Keep cover tight while

circuits are alive. Conduit seals must be installed within 18" (450mm) of

the enclosure.

 Verify that the operating atmosphere of the meter is consistent with the

appropriate hazardous locations certifications.

 If the meter is installed in a high voltage environment and a fault or

installation error occurs, high voltage may be present on any lead

PD6830 Pulse Input Rate/Totalizer Instruction Manual

INSTALLATION

For Installation in USA: The PD6830 must be installed in accordance with the

National Electrical Code (NEC) NFPA 70.

For Installation in Canada: The PD6830 must be installed in accordance with the

Canadian Electrical Code CSA 22.1.

For European Community: The PD6830 must be installed in accordance with the

ATEX directive 94/9/EC and the product certificate Sira 10ATEX116X.

WARNING

Disconnect from supply before opening enclosure. Keep cover

tight while circuits are alive. Conduit seals must be installed within

18" (450mm) of the enclosure.

Wiring connectors are accessed by opening the enclosure. Cover jam screw may

need to be loosened on the cover. To access electrical connectors, remove the 2

captive screws, then disconnect the ribbon cable from the display module and set the

display module aside.

Unpacking

Remove the meter from box. Inspect the packaging and contents for damage. Report

damages, if any, to the carrier. If any part is missing or the meter malfunctions,

please contact your supplier or the factory for assistance.

Pre-Installed Conduit/Stopping Plug

The PD6830 is supplied with one pre-installed conduit/stopping plug for installations

that do not require the use of all three conduit entries. The conduit/stopping plug

includes an internal hexagonal socket recess for removal. The pre-installed plug and

its installation are included in the hazardous area approvals for the PD6830. The

conduit/stopping plug has an internal 12 mm hexagonal socket recess for removal.

For additional conduit/stopping plugs, see ORDERING INFORMATION on page 3.

WARNING

In hazardous areas, conduit and conduit/stopping plugs require the

application of non-setting (solvent free) thread sealant. It is critical

that all relevant hazardous area guidelines be followed for the

installation or replacement of conduit or plugs.

PD6830 Pulse Input Rate/Totalizer Instruction Manual

Mounting

The PD6830 has two slotted mounting flanges that may be used for pipe mounting or

wall mounting. Alternatively, the unit may be supported by the conduit using the

conduit holes provided.

Refer to Mounting Dimensions, page 52 for details.

WARNING

Do not attempt to loosen or remove flange bolts while the meter is

in service.

Cover Jam Screw

The cover jam screw should be properly installed once the meter has been wired and

tested in a safe environment. The cover jam screw is intended to prevent the removal

of the meter cover in a flameproof environment without the use of tools. Using a M2

hex wrench, turn the screw clockwise until the screw contacts the meter. Turn the

screw an additional 1/4 to 1/2 turn to secure the cover. Caution: Excess torque may

damage the threads and/or wrench.

Connections

WARNINGS

 Static electricity can damage sensitive components.

 Observe safe handling precautions for static-sensitive components.

 Use proper grounding procedures/codes.

 If the meter is installed in a high voltage environment and a fault or

installation error occurs, high voltage may be present on any lead or

terminal.

To access the connectors, loosen the cover jam screw (if tightened) with an M2 hex

wrench, remove the enclosure cover and unscrew the two captive screws that fasten

the display module into the enclosure. Disconnect the ribbon cable and remove the

display module. Power and signal connections are made to a barrier terminal

connector in the base of the enclosure. Grounding connections are made to the two

ground screws provided on the base – one internal and one external. Use proper

grounding techniques for explosion-proof areas and observe all local and national

electric codes.

Models configured for DC power (PD6830-A) are provided with a terminal labeled P+

and are wired as shown in Figure 9. Models configured for battery power (PD6830-B)

may optionally be connected to DC power and the battery will function as backup power

when DC is lost. The same power supply may be used to power other circuits including

a PNP-type sensor, however to maintain input isolation, a separate power supply must

be used to power the isolated 4-20 mA transmitter as shown in Figure 10 and/or to

power the Opto-Isolated Flowmeter as shown in Figure 3.

Battery Replacement

Battery-equipped models have a battery charge monitor. When the battery is nearing

the end of its capacity the screen will periodically flash the message LO BATTERY. The

recommended replacement interval for models using the battery as a primary power

source (without DC power at P+ terminal) is three years or within 30 days of the first low

battery indication on the screen. Replacement interval on models that use battery as

backup during short and infrequent DC power loss is ten years. The total is backed up

in non-volatile memory when the low battery monitor trips. It is recommended that an

updated reading be manually backed up prior to changing out the battery. Refer to

information on preparing the meter for battery change in Servicing the Meter (SERVICE)

on page 47 before changing battery.

WARNING

Fire, explosion and burns may result if not handled properly. Do

not recharge, short circuit, crush, disassemble, heat above 100°C

(212°F), incinerate, or expose contents to water.

Battery disposal should be in accordance with applicable

regulations, which vary by location. In many locations trashing of

used batteries is forbidden and disposal is done through local

battery disposal facilities. Spent batteries should be packaged in

such a way as to prevent short circuits during handling and

transport.

NOTICE: Battery may only be replaced with an original Model PDABAT36D supplied

by Precision Digital. Do not recharge battery. Do not replace with used battery.

 Remove cover and display module and disconnect display module ribbon cable.

 Carefully clip and remove the cable ties that were supplied for shipping (if present).

 Remove the spent battery and prepare it for disposal.

 Install new PDABAT36D into battery clip with polarity as shown in Figure 11.

 Reconnect and fasten display module. Install enclosure cover.

 Resume operation.

SETUP AND PROGRAMMING

There is no need to recalibrate the meter for frequency in

Hz when first received from the factory.

The meter is factory calibrated for Hz prior to shipment.

The calibration equipment is certified to NIST standards.

Overview
