INSTALLATION CONSIDERATIONS DESCRIPTION

ANTI-ROTATION ARM MOUNTING
GUIDELINES
2. Mount Anti-Rotation Arm perpendicular to motor
shaft axis of rotation. Arm mounting bolts and associated
rod bearings should be parallel to motor shaft also. (Viewed
from above.)
The Anti-Rotation Arm stabilizes the SHAFTach and keeps
it from rotating as the motor shaft rotates. To mount the
Anti-Rotation Arm, use these guidelines:
3. Mount Anti-Rotation Arm 90° to a line established
between mounting board, mounting hole, and shaft centerline. (Viewed from end.)
1. Mount SHAFTach with conduit entry ports positioned horizontally.
4. Mount SHAFTach as close as possible to the motor
with the mounting board closest to the motor.

INSTALLATION CONSIDERATIONS
The Avtron Model M585 SHAFTach™ Pulse Generator is a
zero-speed incremental rotary transducer. When mounted
to a machine shaft, it provides a specific number of electrical pulses per revolution that are proportional to the shaft’s
rotation. The photoelectric sensing system and electronics
are protected by an O-ring sealed, cast aluminum housing.
In a conventional pulse generator installation, a flexible coupling is used to compensate for small shaft misalignment
and runout of the driving shaft. Often this misalignment
and runout reduce the life of the mechanical parts and may
cause unwanted modulation of the electrical output signal.

The M585 design eliminates the need for shaft couplings,
adapter flanges, or accessory mounting faces. The unit
employs a keyless shaft mount to lock the M585’s rotor to
a 1.125" diameter shaft. The hub is designed to maintain
concentricity of the rotor and shaft, providing an accurate
output signal. An anti-rotation arm prevents rotation while
allowing for shaft end float.

BASIC MODEL NUMBER
While misalignment is not a problem with the SHAFTach™,
circular runout of the driving shaft may cause a once per
revolution frequency modulation of the output signal. Depending upon the application, this may or may not be acceptable. Typically, a runout of 0.001 TIR or less will not
have an adverse effect.
ITEMS REQUIRED FOR INSTALLATION
The following special items are required for installation:
13⁄4" Spanner Wrench - Avtron P/N 484017 for
the 13⁄4" diameter clamping nut
McMaster-Carr P/N 6975A17
21⁄2" Spanner Wrench - Avtron P/N 484018 for
the 21⁄2" diameter bearing locknut
McMaster-Carr P/N 6975A19
Thread locking liquid - Locktite 242, supplied
Metal Putty (Required for machine shafts with a keyway.)
UNPACKING INSTRUCTIONS
The M585 is supplied with four main items: the pulse
generator with integral specific option package, the
anti-rotation arm, the mounting board with attaching hardware, and the V-ring seal. Check and verify all components
received as ordered. Check for external damage or missing
items. This must be handled by the customer through the
shipper.
Check nameplate against your requirement to make sure
proper style, output, PPR, options, and voltage have been
received.
INSTALLATION
MACHINE SHAFT PREPARATION
Preparing the machine shaft prior to Pulse Generator installation is essential in providing an adequate barrier against
environ­mental contamination. In some cases, a separate stub
shaft (1.125" D x 4.5" long) will be installed on the motor. To
prepare the machine shaft that the M585 is to be installed on,
conduct the following procedures (see figures):
1. Remove from the M585 the four ⁄4-20 UNC machine
screws which hold the end cap on the cover plate.
2. Remove the end cap, O-Ring, and wave spring, noting
the location of each to assist in reassembly.
1
CAUTION
SPANNER WRENCHES MUST BE USED DURING THE
FOLLOWING PROCEDURES. Using a substitute can distort
the 13⁄4" nut and damage the unit. Do not try to remove the
21⁄2" bearing locknut at any time. This locknut is factory adjusted
for optimum M585 performance.
NOTE
Two spanner wrenches, which are required for M585 installation, accommodate the 13⁄4" and 21⁄2" nuts found under the cap.
3. Holding the 21⁄2" bearing locknut, remove the 13⁄4" diameter clamping nut and slide out the internal compression sleeve.
4. Verify that the compression sleeve can be installed by
hand on the shaft where the unit is to be installed. File any burrs
that obstruct sleeve installation and lightly oil the shaft.
5. If a keyway or flat exists on the shaft, provide a sealing
medium or true shaft back to round using metal putty or equal.
6. Return the compression sleeve to the M585 hub.
7. Thread the 13⁄4" clamping nut onto the M585 by hand until
resistance is felt. DO NOT TIGHTEN AT THIS TIME.
M585 types have an O-ring inside their hollow shafts at the motor end. In addition, in THRU SHAFT types, the clamping nut
has an O-ring on the inside, plus the outside of the clamping nut
requires lubrication for the radial lip seal per step 8b. Slide the
M585 onto the machine shaft, mounting board first. Ideally, the
M585 housing will be 1⁄2" to 1" from the motor or machine housing, but this may vary depending on the machine profile and the
anti-rotation arm clearance requirements. Consider shaft end
float when positioning the M585.
4a. FOR STUB SHAFT APPLICATIONS, place the M585
31⁄4" to 4" onto the shaft. The end of the machine shaft must extend completely through the M585 compression sleeve and be
approximately flush with the end of the 13⁄4" clamping nut.
4b. FOR THRU SHAFT APPLICATIONS, position the M585
as required.
5. Attach free end of the Anti-Rotation Arm to the
1
⁄4" mounting board using the shoulder bolt provided.
6. Remove 13⁄4" clamping nut and apply liquid thread locker
to the threads. (Locktite grade 242, supplied, should be used in
most applications.)

ENVIRONMENTAL
CONSIDERATIONS
Special attention is to be given to conduit runs, interconnection
wiring and NEMA type enclosure mounting. In those applications
where ambient temperatures are controlled within 40°F and high
humidity/washdown are not present, position the flexible conduit
with a slight sag to prevent any condensation from entering the
SHAFTach via conduit.
In harsh environments, which include temperature extremes, high
humidity, equipment washdown or atmosphere contamination,
extra care is required for interconnection. Follow these steps to
reduce potential problems:
PULSE GENERATOR INSTALLATION
1. Always mount connection points, conduit couplings, junction boxes, etc., lower than actual generator.
2. Venting of generator is beneficial. One method is to take
conduit run outside of hostile area where practical. (Applies to
conduit installations only.)
3. For washdown areas, shroud or otherwise cover the
SHAFTach to prevent direct water spray. Do not attach the shroud
directly to the generator.
4. Keep conduit outputs and axis of rotation horizontal.
5. Purging of SHAFTach should be reviewed with Avtron.
M585 SPECIFICATIONS
Installing the M585 and Anti-Rotation Arm:
1. The free end of the Anti-Rotation Arm must be secured

INSTALLATION CONSIDERATIONS
The Avtron Model M585 SHAFTach™ Pulse Generator is a
zero-speed incremental rotary transducer. When mounted
to a machine shaft, it provides a specific number of electrical pulses per revolution that are proportional to the shaft’s
rotation. The photoelectric sensing system and electronics
are protected by an O-ring sealed, cast aluminum housing.
In a conventional pulse generator installation, a flexible coupling is used to compensate for small shaft misalignment
and runout of the driving shaft. Often this misalignment
and runout reduce the life of the mechanical parts and may
cause unwanted modulation of the electrical output signal.

The M585 design eliminates the need for shaft couplings,
adapter flanges, or accessory mounting faces. The unit
employs a keyless shaft mount to lock the M585’s rotor to
a 1.125" diameter shaft. The hub is designed to maintain
concentricity of the rotor and shaft, providing an accurate
output signal. An anti-rotation arm prevents rotation while
allowing for shaft end float.

BASIC MODEL NUMBER
While misalignment is not a problem with the SHAFTach™,
circular runout of the driving shaft may cause a once per
revolution frequency modulation of the output signal. Depending upon the application, this may or may not be acceptable. Typically, a runout of 0.001 TIR or less will not
have an adverse effect.
