INTRODUCTION

1.0 Safety Summary

High current, voltage, and rotating parts can cause serious or fatal injury. The use of electric machinery, like all other usesof concentrated power and ro tating eq uipment, m ay b e h azardous. In stalling, o perating, an d m aintaining electric m achinery should be perf ormed by qualified personnel, in accordance with applicable provisions of the National Electrical Code and sound local practices . Failure to com ply with these precautions or w ith specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument.©Dynapar assumes no liability

for the customer's failure to comply with these requirements.

Rotating Machinery

Avoid contact with rotating parts. Avoid by-passing or rendering inoperative any safety guards or protection devices. Avoid extended exposure in close proximity to machinery with high noise levels. Use proper care and procedures in handling, lifting, installing, operating and maintaining the equipment.

Before Installation

Safe maintenance practices with qualified personnel is imperative. Before starting maintenance procedures, be positive that,

(1) equipment connected to the shaft will not cause mechanical rotation, (2) main machine windings have been disconnected and s ecured f rom all electrical pow er s ources, an d (3) all acces sory dev ices as sociates with th e work area have been deenergized. If high potential insulation test is required, follow procedures and precautions outlined in NEMA standards MG-1.

Grounding

Improperly grounding the frame of the machine can cause serious or f atal injury to pers onnel. Grounding of the machine frame and structure should comply with the National Electrical C ode and with sound local practices . Check wiring diagram before connecting power.

Do Not Operate In An Explosive Atmosphere

Do not operate th e instrument in the presence of flammable gases or f umes. Operating any electrical instrument in such an environment constitutes a definite safety hazard.

Keep Away From Live Circuits

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified maintenance personnel. Do n ot replace com ponents w ith pow er cable con nected. T o av oid in juries, alw ays disconnect power and discharge circuits before touching them.

Do Not Substitute Parts Or Modify Instrument

Do not ins tall substitute parts or pe rform any unauthorized modification to the instrument. Introducing additionalzardsh is dangerous. Return the instrument to an authorizedDynapar representative for service and repair to ensure that safetyfeatures are

maintained.

CAUTION!: Crucial information, that must be read and followed regarding safety and unit functioning.

DO THIS!: Additional procedure, that must be read and followed, without safety issues.

NOTE: Useful information that should be read.

QUESTION: Helpful hints to answer your possible questions.

1.1 General

These instructions do not claim to cover all details o f v ariation in eq uipment o r to p rovide f or ev ery p ossible contingency or hazard to be met in connection with installation, operation, and service. Should further information be

desired or s hould particular problems arise which are n ot covered sufficiently for the purchaser’s purposes, please contact Dynapar, or one of its designated representatives.

1.2 Description

The RIM Tach® 8500 (and henceforth 8500 Quad) is a high performance, reliable Digital Tachometer, designed to provide position and velocity feedback from both AC and DC electric m otors with pulse counts ranging from 60 through 1200 pulses per revolution.

The RIM Tach	8500 allows up to 2 s ensor modules, whereas the Rim Tach 8500 Quad allows
up to 4.

Designed for NEMA 180 through 500 diameter AC or DC motor frames, the RIM Tach 8500 utilizes rugged ductile iron casting construction, and provides interchangeable sensor modules and a magneto-resistive technology capable

of withstanding th e h arshest in dustrial en vironments. T his en sures a precis e an d con sistent dig ital m otor s peed feedback.

The NorthStar RIM Tach 8500	is mounted directly to th e motor frame and utilizes a paten t pending, heavy-duty,
®
one piece, magneto-resistance	sensor module with en capsulated s urface m ount electron ics.	T	he en capsulation
provides res istance to w ater, oil m ist, dirt, h igh tem peratures, an d oth er h arsh en vironments.		The	sensor module

includes a 10pin qu ick con nector requ iring on ly a s crewdriver f or f inal electrical in stallation. T he n on-contact

magneto-resistive se nsor	a nd r ugged m agnetized p ulse	w heel a re d esigned and machined to function properly
without any adjustments	when assembled to a NEMA	180 ty pe C F ace (8.5- inch diam eter) m otor f rame an d

accessory mount. T here are n o bearings to f ail or requ irements for flexible couplings since the magnetized pulse wheel assembly is attached directly to th e shaft. T he RIM T ach8500 provides precise, reliable speed signals for many monitoring and control applications, and is a standard feedback device for AC and DC variable speed drives. The unit is bi-directional providing square wave outputs.

2.0 Inspection and Unpacking

Inspect shipping container for external damage. A ll claims for damage (apparent or con cealed) or partial los s of shipment must be made in writing toDynapar within (5) days from receipt of goods. If damage or loss is apparent, please notify the shipping agent immediately.

Open shipping container and locate th e packing list. T he packing list is included to verify that all components, accessories, and manual were received. Please use the packing list to ch eck off each item as the unit is unpacked. In spect for damage. Dynapar recommends that the shipping container be retained for future shipping, storage, or return to factory purposes.

If any equipment was damaged in transit, be s ure to f ile proper claim s promptly with the carrier an d insurance company. Please advise Dynapar of such filing. In case of parts shortages, adviseDynapar immediately. Dynapar

cannot be responsible for any missing parts unless notified within 60 days of shipment.

2.1 Painting Considerations

The enclosure may be painted. Please pay attention to the following considerations.

•Do not hinder the latches on the connector if the connector is painted.

•If the enclosure is painted before the sensor module(s) is added, be sure to mask off the area where the sensor module(s) will be placed. The module must mate directly to the enclosure. Failure to do this will degrade the alignment of the system and may cause it to fail.

•Ensure excess paint runoff does not clog Enclosure drain holes.

2.2 Motor Facing and Shaft

The RIM Tach® 8500 has been designed to be mounted on a 8.5 inch diameter 180 C Flange that meets or exceeds the NEMA MG1-4 Standards. To prepare the motor facing and shaft for installation, perform the following steps.

Clean outer rim and surface of motor facing and shaft of paint, grease, dirt and other debris where RIM Tach® 8500 unit contacts motor or accessory. Also ensure that mating surfaces have not been damaged and that unit will fit squarely on motor.

Ensure there is no paint, burrs, protrusions, or deformations on the motor facing or shaft. If the enclosure does not fit squarely on the motor facing, the alignment between the sensor module and the magnetic pulse wheel may be degraded.

Apply a thin layer of corrosion preventative or oil to motor facing and shaft to aid assembly and provide some corrosion protection.

Ensure motor facing and shaft are free from paint, burrs, protrusions, and deformations
