THIN-LINE IIITM directly replaces THIN-LINE IITM and THIN-
LINETM models. THIN-LINE III models have Rev Code BA
or later. Special option 4xx selects an alternate PPR code
definition. Example: PPR Code 0, Special Option Code 401
= 1270 PPR (Left), No Right Output.
DESCRIPTION
The Avtron AV115 is a modular, two piece incremental encoder (also
known as a tachometer or rotary pulse generator). It provides a two
phase, A Quad B frequency (pulse) output, with complements. The
AV115 mounts on a 115mm C-Face, also known as a B-Flange.
Because the AV115 is modular, there are no bearings or
couplings required. This, combined with the latest magnetoresistive
(MR) sensor technology, allows the AV115 to provide superior
mechanical performance and increased reliability. An Avtron AV115 can
be configured with one or two independent outputs. Each output has
six signals: (A, B) 90° out of phase, with complements (A, B). A marker
pulse with complement (Z, Z) is also provided.
Output resolution on the AV115 is determined by the sensor only.
Unlike older models, any PPRs can be mixed and matched. Selection
of the rotor is based only on the shaft mounting requirements (and not
PPR).

INSTALLATIONS
Refer to the back page of these instructions for outline and mounting
dimensions. Axial float or endplay must be less than ±1.27mm.
In preparation for installing the Model AV115 Encoder, it is first
necessary to clean both the accessory motor shaft and the mounting
face. These surfaces must be inspected and any paint, burrs, or other
surface imperfections removed.
Installation procedures should be performed only by qualified
personnel. Safety precautions must be taken to ensure machinery
cannot rotate and all sources of power are removed during installation.

SPECIFICATIONS
ROTOR INSTALLATION
The motor shaft must project at least 16mm from the motor face. For
set screw rotors only: Apply anti-seize compound to the motor shaft.
For all rotors: Slide the rotor onto the shaft with the marking “This side
out” facing out (away from the motor face). The rotor centerline must
match the sensor centerline. To accomplish this, use the rotor locating
gauge (A28503) and slide the rotor onto the shaft until it is in the
proper position as shown in Figure 1. If a gauge is not available, use
the stator housing alignment grooves as show in Figure 3.
STANDARD CAM SCREW ROTOR INSTALLATION
Turn the cam screws of the rotor in the directions shown on the rotor
to engage the cams. Tighten to 5.6 - 6.8 N-m (See Figure2) using the
3mm hex wrench. Total cam screw rotation will be less than one turn.
CAUTION
Do not adjust the cam screws before motor shaft
mounting; bottoming out the screws, or backing them
out excessively, can lead to insufficient shaft holding
force. Thread locker is preapplied on the cam screws.
LARGE BORE SET SCREW ROTOR INSTALLATION
Apply thread locker to the rotor set screw holes, preferably from the
inside of the rotor bore before mounting. Tighten the rotor set screws
to 0.56 +/- 0.11 N*m (5 +/- in*lb). Large bore rotor set screw is M3
and should be tightened using a torque-measuring 1.5mm-drive hex
wrench
CAUTION
Use only a T-handle or torque hex wrench to tighten
set screws; using a right angle wrench will not provide
enough holding force, and the rotor may slip.
WARNING
Overtightening can lead to deformation &/or damage to
the rotor.

STATOR HOUSING INSTALLATION
The stator housing is attached to the motor using four socket head
cap screws M10 x 0.5 x 20mm long, locating on a 150mm bolt circle.
Longer bolts (not included), are required for sandwich installation
between a motor and a brake. Install the four mounting bolts using
thread locker and torque to approximately 27 to 40 N-m using the
8mm T-handle hex wrench.
VERIFY ROTOR LOCATION
To ensure the rotor is properly located on the shaft: remove the back
cover if factory-preinstalled, and verify that the outer face of the rotor is
at the same depth as the alignment grooves, using a straight edge tool.
(Figure 3)
CAUTION
Do not use silicone sealants or caulk of any kind on the
motor or encoder face; these can cause misalignment
or sensor scraping damage. The AV115 electronics are
fully sealed; water may enter and leave the rotor area
as needed. A drain hole option is available if frequent
moisture buildup is expected.
COVER INSTALLATION
Covers must not interfere with the motor shaft or rotor. The longest
shaft that can be used without interfering is 17.5mm with a standard
flat cover (Cover Style option “F”) and 63.5mm with an extended “pie
pan” cover (Cover Style option “E”). Through shaft covers with seals are
available for other applications (Cover Style option “T”).
EXTENDED COVER MOUNT
(Cover Style option “E”)
The extended cover mounts to the encoder housing using quantity 4
#6-32 x 0.31" screws, lock washers, and thread locker.
THRU SHAFT AND FLAT COVER INSTALLATION
(Cover Style option “T” and “F”)
The housing has a machined step in the outboard face to accept the
cover and a recessed groove for the retaining ring. Insert the cover,
line up ears on cover, smooth side facing out, fully into the machined
step until it seats against shoulder. Using a spiral assembly method,
install the retaining ring by first inserting the squared off end into the
machined groove. Flex the ring and insert it into the groove walking
it around the perimeter (A flat blade screwdriver can be used). Final
position should have the ring fully seated into groove. Remove the
cover by reversing above procedure, starting with the tang end.
V-RING INSTALLATION FOR THRU SHAFT COVERS
(Cover Style option “T”)
For thru shaft covers, verify that the shaft passes completely through
the hole in the cover. Apply a small amount of silicone lubricant to
the cover plate around the thru shaft hole. The V-Ring seal should
compress axially when it is pressed against the clean, smooth face
of the cover plate. See Figure 4 for proper installation and V-Ring
compression.
WIRING
CAUTION
Be sure to remove power before wiring the encoder. Be
sure to ground the cable shield: It can be connected to
case ground at the encoder, or grounded as the receiving
device, but should not be grounded on both ends. See
note below for Danaher/Northstar wiring.
Refer to the wiring diagrams for specific information on each option.
The AV115 can be wired for single phase or two phase, either with
or without complements, with or without markers. For bidirectional
operation, Phase A channel leads phase B channel for clockwise shaft
rotation as viewed from the anti-drive or accessory end of the motor
(AV115 mounting end).
NOTE
Wiring option “G” provides a pinout compatible with
NorthstarTM encoders, with a cable shield connection on
pin 10. Note that this option does not ground the shield;
Avtron still recommends grounding the shield at the
drive end of the cable for all wiring options.
CORRECTIVE ACTION FOR PHASE REVERSAL
1) Remove Power.
2) Exchange wires on cable, either at encoder cable end,
or at speed controller end (but not both).
a) Single Ended 2 Phase Wiring (see wiring diagram)
Exchange A and B at the use end of the wires.
b) Differential 2 Phase Wiring (see wiring diagram)
Exchange either A with A– in the phase A pair OR
B with B– in the phase B pair but NOT both.
3) Apply Power.
4) Verify encoder feedback is correct, using hand rotation
of shaft, or jog mode of the speed controller.
Interconnecting cables specified in the wire selection chart are based
on typical applications. Physical properties of cable such as abrasion,
temperature, tensile strength, solvents, etc., are dictated by the specific
application. General electrical requirements are: stranded copper,
22 through 16 AWG (Industrial EPIC connector type options can use
14 AWG), each wire pair individually shielded with braid or foil with
drain wire, .05 uf of maximum total mutual or direct capacitance,
outer sheath insulator. See specifications for maximum cable length.
Stranded 22 AWG wire should not be used for cable runs greater then
61 meters. If 22 AWG is used with EPIC type connector options the wire
ends should be tinned.
FAULT-CHECK
After power-up and the rotor position is checked by the sensor, the
Fault-Check LED will turn GREEN.
If the adaptive electronics reach their adjustment limit for any reason,
the Fault-Check alarm and LED will notify the drive and operator of an
impending failure. The LED will turn RED if the Adaptive Electronics
reach their adjustment limit. This output occurs before an actual
failure, allowing steps to be taken to replace the unit before it causes
unscheduled downtime. Fault-Check annunciation is available as an
“alarm” output through the connector and as an integral LED.
If there is a wiring error, such as an output being shorted to ground
or +V or another output, the Fault-Check LED will turn ORANGE. The
ORANGE LED may blink intermittently, depending on voltage and
severity of short.
TROUBLESHOOTING
If the drive indicates a loss of encoder/tach fault and the AV115 fault-
check LED is not illuminated, check the encoder power supply. If power
is present, check polarity; one indicator of reversed power supply is
that all outputs will be high at the same time. If the drive indicates
encoder fault, but the LED shows GREEN, then check the wiring
between the drive and the encoder. If the wiring appears correct and
in good shape, test the wiring by replacing the AV115. If the new unit
shows GREEN, and the drive still shows encoder loss/tach fault, then
the wiring is faulty and should be repaired or replaced.
If the alarm output and/or LED indicate a fault (RED):
1. Remove the rear cover, and use the built-in gauge to check the
location of the rotor (see Figure 1). Ensure the label marked “This side
out” is facing away from the motor.
2. Remove the AV115 from the motor. Clean the housing mounting
surface for the AV115 housing. Ensure the AV115 is directly mounted
on the motor, with no sealant, gasketing, or other materials, and is
firmly bolted in place.
If the alarm output and/or LED indicate a fault (RED)
On a properly mounted AV115 and the rotor is properly located, replace
the AV115 sensor.

An oscilloscope can also be used to verify proper output of the encoder
at the encoder connector itself and at the drive/controller cabinet.
If the outputs show large variations in the signals at steady speed
(jitter or “accordion effect”, see figure 5), check rotor position. If the
rotor position is correct, the motor or shaft may be highly magnetized.
Replace any magnetized material nearby with non-magnetic material
(aluminum, stainless) (especially shafts). For GE CD frame motors and
similar styles, Avtron offers non-magnetic stub shafts. If variations
persist, consider replacing the encoder with super-shielded models,
option -005, or use retrofit shielding kits AVSKxxx yy z, where
xxx=model (ex: 56A), yy=rotor (ex: CB), and z=cover (ex: F).
If the alarm output and/or LED indicate a wiring fault (ORANGE):
Remove all output wires/connections (A,A/,B,B/,Z,Z/). The LED should
turn GREEN. If the LED does not turn GREEN, the encoder is not
receiving enough voltage at +V to properly operate. Correct input
voltage problem at power supply or cabling.
If the LED turns GREEN once all outputs are disconnected, reconnect
each output, one at a time, monitoring for ORANGE LED. For partial/
resistive short circuits, the LED may take a few minutes to turn
ORANGE. To speed the troubleshooting process, if possible, spin the
encoder while replacing individual output connections. This will make
the ORANGE LED condition occur faster. Once the shorted output(s)
are located, correct the shorting condition, and the encoder LED should
remain GREEN.
If the LED is OFF, but power is being applied to the encoder, check
the output voltage level at A, A/,B, B/. If all outputs are ON (≈+V), the
connections to +V and COM are reversed. Swap connections between
+V and COM; the LED should turn GREEN.
NOTE:
Do not use rotors from THIN-LINE I (M56, M56S, M67,
M85, M115) with THIN-LINE III. This will cause incorrect
PPR output, but the Encoder LED will remain green.
ENCODER REMOVAL
The AV115 stator housing can be removed by loosening and removing
the socket head cap screws.
CAM SCREW ROTOR REMOVAL
Disengage the (2) cam screws by turning them counterclockwise less
than 1 full turn. The cam heads will visibly move away from the shaft.
Remove the rotor by hand by pulling it away from the motor. If the rotor
will not move, do NOT use a gear puller, and do not use a heat gun.
Instead, insert two M6 screws, >25mm length into the Jack Screw
Holes shown in Fig 2. Alternately tighten the screws to push the rotor
away from the motor and remove it.
LARGE BORE SET SCREW ROTOR REMOVAL
Disengage the (2) set screws by turning them counterclockwise until
removed from the rotor. Retain the set screws. Remove the rotor by
hand by pulling it away from the motor. If the rotor will not move, do
NOT use a gear puller, and do not use a heat gun. Instead, pry the
rotor away from the motor gently, being careful to only pry against the
rotor metal hub and not the magnetic outer strip.
