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 rotating equipm
should be performed by qualified personnel, in accordance with applicable provisions of the National Electrical Code and
sound local practices. Failure to comply with these precautions or with 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 renderi
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 m
(1) equipment connected to the shaft will not cause mechanical rotation, (2) main machine windings have been disconnected
and secured from all electrical power sources, and (3) all accessory devices associates with the work area have been deenergized. If high potential insulation test is required, follow procedures and precautions outlined in NEMA standards MG-1.

1.1 General
These instructions do not claim to cover all details of variation in equipment or to provide for every possible contingency or
hazard to be met in connection with installation, operation, and service. Should further information be desired or should
particular problems arise which are not covered sufficiently for the purchaser’s purposes, please contact Dynapar, or one of
its designated representatives.
1.2 Description
The NorthStar SLIM Tach
designed for fast, easy mounting onto a standard NEMA 8.5 inch motor face. The basic design philosophy follows. The
encoder frame is mounted onto the C-Face flange of a motor. This positions the sensor and contains the electronics. The
magnetic pulse wheel on the motor shaft has magnetic pulses imprinted on its outside surface. As the motor spins, the
passing magnetic pulses actuate the magnetoresistive sensor. The resulting electronic signals are processed into square wave
signals by the internal electronics.
