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 uses of 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 qu alified pers onnel, in accordance w ith applicable provisions of the National Electrical Code and sound local practices . Failure to com ply with these precautions or w ith specific warnings els ewhere 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 prot ection 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 im perative. 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 w ith th e w ork 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 th e m achine can cau se s erious or f atal in jury to pers onnel. Grou nding of th e m achine 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 th e presence of f lammable gases or f umes. Operatin g 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 pa rts or pe rform a ny unauthorized modification to the instrument. Introducing additional hazards is dangerous. Return the instrument to an authorized Dynapar representative for service and repair to ensure that safety features 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.

2.0 Inspection and Unpacking

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

Open shipping container and locate the packing list. T he packing list is included to verify that all components, accessories, and manual were received. Please use the packing list to check 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 an y equ ipment w as dam aged in tran sit, be s ure to f ile proper claim s prom ptly w ith th e carrier an d in surance company. Please adv ise Dynapar of such filing. In cas e of parts shortages, advise Dynapar 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 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 contacts motor or accessory. Also ensure that mating surfaces have not been damaged and that unit will fit squarely on motor.

8500 has been designed to be mounted on a 8.5 inch diameter 180 C Flange that meets or exceeds the NEMA

8500 unit

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
