PD6800 Loop-Powered Process Meter Instruction Manual

INTRODUCTION

The PD6800 is a rugged, explosion-proof loop-powered meter fully featured for

demanding applications in hazardous areas or in the harshest environmental

conditions. The meter derives all of its power from the 4-20 mA loop. It is

programmed using the four SafeTouch®through-glass buttons, without removing the

cover, and can be scaled with or without a calibration signal. The numeric display will

read up to 99999 and the alphanumeric display can 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 lets you see the

display under any lighting condition and can be powered from either the 4-20 mA

loop or from a separate DC power supply.

The enclosure is provided with two 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

PD6800 Loop-Powered Process Meter Instruction Manual

INSTALLATION

For Installation in USA: The PD6800 must be installed in accordance with the

National Electrical Code (NEC) NFPA 70.

For Installation in Canada: The PD6800 must be installed in accordance with the

Canadian Electrical Code CSA 22.1. All input circuits must be derived from a CSA

approved Class 2 source.

For European Community: The PD6800 must be installed in accordance with the

ATEX directive 94/9/EC and the product certificate Sira 10ATEX1116X.

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. 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 PD6800 is supplied with one pre-installed conduit plug for installations that do

not require the use of both conduit entries. The conduit/stopping plug includes an

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

is included in all hazardous area approvals of the PD6800.

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.
