PD683 & PD688 Loop-Powered Meters Instruction Manual

INTRODUCTION

The PD688 is an intrinsically safe and non-incendive loop-powered meter

approved for hazardous area locations. The PD683 is a general-purpose

loop-powered meter for safe area applications. The four front panel but-

tons make the setup and programming an easy task. Five digits, bar-

graph, engineering units, and trend arrows provide a clear and attractive

presentation of the process.

The square root and programmable exponent functions allow for condi-

tioning of signals from non-linear transmitters without adding external

components to the system and the convenience of scaling without a cali-

brated signal source make the PD683 & PD688 the ideal choice for pro-

cess display applications.

SAFETY INFORMATION

Installation and service should be per-

formed only by trained

service personnel. Service requiring

replacement of internal components

must be performed at the factory.

CAUTION: Read complete

instructions prior to installation

and operation of the meter.

PD683 & PD688 Loop-Powered Meters Instruction Manual

INSTALLATION

There is no need to remove the meter from its case to com-

plete the installation, wiring, and setup of the meter.

Unpacking

Remove the meter from box. Inspect the packaging and con-

tents 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.

Panel Mounting

•Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm

x 45 mm). Refer to Mounting Dimensions, page 32 for more details.

•Clearance: allow at least 4" (102 mm) behind the panel for wiring.

•Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Minimum steel/stainless steel panel thickness to maintain watertight

rating: 0.06" (1.5 mm).

Note: A steel or stainless steel panel rather than plastic is

recommended in cases where a watertight or dust-tight seal is

required between the meter and the panel.

•Remove the two mounting brackets provided with the meter (back-off

the two screws so that there is ¼" (6.4 mm) or less through the

bracket. Slide the bracket toward the front of the case and remove).

•Insert meter into the panel cutout.

•Install mounting brackets and tighten the screws against the panel.

To achieve a proper seal, tighten the mounting bracket screws

evenly until meter is snug to the panel along its short side. DO NOT

OVER TIGHTEN, as the rear of the panel may be damaged.

Wiring Connections

Signal connections are made to a four-terminal removable connector. This

section is only intended for the PD683.

PD688 installation must be performed in accordance with Control

Drawing LIM688-2 in order to meet agency approval ratings.

Observe all safety regulations. Electrical wiring

should be performed in accordance with all agency

requirements and applicable national, state, and lo-

cal codes to prevent damage to the meter and en-

sure personnel safety.
