CHAPTER 1
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 equipment, may be hazardous. Installing, operating,
and maintaining electric machinery 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 rendering inoperative any safety guards or protec-
tion 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 proce-
dures, be positive that, (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 de-energized. 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 fatal injury to personnel. Grounding
of the machine frame and structure should comply with the National Electrical Code and with sound local
practices. Check wiring diagram before connecting power.
Do Not Operate In An Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or fumes. 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 not replace components with power cable connected.
To avoid injuries, always disconnect power and discharge circuits before touching them.
Do Not Substitute Parts Or Modify Instrument
Do not install substitute parts or perform any 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.
Dangerous Procedure Cautions
A CAUTION heading precedes potentially dangerous procedures throughout this manual. Instructions in the
warnings must be followed.

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 WIND56 is a modular digital encoder. This magnetoresistive encoder sensor-based unit has
been designed for fast, easy mounting onto a standard NEMA 56C motor face. The basic design philoso-
phy is as 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.

2.0 Inspection and Unpacking
Inspect shipping container for external damage.All claims for damage (apparent or concealed) or partial loss
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. The 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. Inspect for damage. We recommend that the shipping container be retained for future shipping,
storage, or return to factory purposes.
If any equipment was damaged in transit, be sure to file proper claims promptly with the carrier and insurance
company. Please advise us of such filing. In case of parts shortages, advise us immediately. Dynapar cannot
be responsible for any missing parts unless notified within 60 days of shipment.
2.1 Motor Facing and Shaft
To prepare the motor facing and shaft for installation, perform the following steps. See Figure 2.
1. Clean outer rim and surface of motor facing and shaft of paint, grease, dirt, and other debris where
WIND56 unit contacts motor or accessory. Also ensure that mating surfaces have not been damaged and
that unit will fit squarely on motor.
2. Apply a thin layer of corrosion preventative or oil to motor facing and shaft to aid assembly and provide
some corrosion protection.
CHAPTER 2
INSTALLATION
NOTE
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.

2.2 To install the encoder frame, perform the following steps:
NOTES:
1. The encoder and the wheel are a matched set and are not interchangeable. The serial numbers should be
double checked to ensure proper assembly and performance. The serial number on the encoder is found
on the encapsulation (example: 102). The serial number on the wheel is found on the front of the wheel
(example: 102W).
2. The ENDURANCE 56 wheel consists of two parts:
A. The hub (secured to the shaft).
B. The pulse wheel (secured to the hub).
1) Install Hub: Position the hub so that the large flange faces the motor. Slide the hub on the motor shaft
until it makes contact with the machined step. See Figure3. If there is not a machined step, see Figure 3a to
illustrate how to use the installation spacer to align the hub. The hub is now properly aligned.Apply Loctite
222 to the two 10-32 UNC set screws. Making sure the hub is firmly seated against the step or installation
spacer, use a 3/32 inch hex wrench to tighten the screws to a nominal 25 in-lbs.
2) Install Encoder Housing: Orient the encoder frame so the 4.5 inch I.D. surface will fit over the 4.5 inch C
flange (encapsulated side toward the motor). Do not bolt down.
3) Install the Pulse Wheel: While holding the encoder frame, position the pulse wheel so the label This Side
Out is visible. Slide it unto the shaft until it makes contact with the hub. Rotate the pulse wheel on the hub so
the three mounting holes are aligned. It may be helpful to use two 1/4-20 UNC screws lightly threaded into
the pulse wheel to help position the pulse wheel. Apply Loctite 222 to the three 8-32 UNC button head
screws. Use a 3/32 inch hex wrench to tighten the screws into the pulse wheel to a nominal 20 in-lbs. Re-
move the two 1/4-20 UNC screws from the pulse wheel.
4. Install Brake Plate and Encoder Housing Hardware: Place the brake plate onto the motor shaft so the
four counter bore holes align with the holes in the encoder frame. Insert the four 3/8-16 UNC screws through
the brake plate and encoder frame and into the motor frame. Use a 5/16 inch hex wrench to tighten a nominal
25 in-lbs.

2.3 Electrical Installation
Electrical connections are made to the sensor module through a standard 1/2 inch NPT liquid tight flexible
conduit. The nipple length may be changed to extend the outlet box if desired. Interconnection cable recom-
mendations are as follows: stranded copper, 22 through 16 gage, braided or foil with drain wire shielding
0.05 µF maximum total mutual or direct capacitance, outer sheath insulated. Shrink tubing may be placed
over any wires without insulation. For lengths over 100 feet, use 18 gage or larger, to a maximum of 1000
feet. If shielded twisted pair wire is used, do not cross channels. Keep each pair of complementary channel
outputs together in a single twisted pair (e.g., A and A complement).

NOTE
The shield in the sensor module is isolated from the frame of the
encoder for maximum noise immunity. The shield wire or pin should
be connected to the shield of the cable and that of the drive or other
receiving device.
