Avtron AV115 User manual

Installation procedures should be performed only by qualified
personnel. Safety precautions must be taken to ensure machin-
ery cannot rotate and all sources of power are removed during
installation.
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 guage 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.
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 comple-
ments. 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 magneto-
resistive (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 require-
ments (and not PPR).
NOTE
Special option 002 selects an alternate PPR code
definition. Example: A-128 PPR with option code
000. A*-1270 PPR with option code 002.
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 pulse generator, 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.

screws to 2 N-m using the 2mm T-handle hex wrench.
CAUTION
Use only a T-handle or torque hex wrench to tighten
set screws; using a right angle wrench will not pro-
vide enough holding force, and the rotor may slip.
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 mount-
ing 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 mis-
alignment 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 lon-
gest 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 insert-
ing 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 encod-
er. 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 bidi-
rectional operation, Phase A channel leads phase B channel for
clockwise shaft rotation as viewed from the anti-drive or acces-
sory 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 dic-
tated by the specific application. General electrical requirements
are: stranded copper, 22 through 16 AWG (Industrial EPIC con-
nector 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 specifica-
tions 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.
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 prop-
erly mounted AV115 and the rotor is properly located, replace
the AV115 sensor.

An oscilloscope can also be used to verify proper output of the
AV56 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, stain-
less) (shafts, etc). If variations persist, consider replacing with
super-shielded models, option -005.
NOTE:
Do not use rotors from THIN-LINE I (M56, M56S,
M67, M85, M115) with AV115. This will cause incor-
rect PPR output, but the AV115 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 counterclock-
wise 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 mag-
netic outer strip.

ALARM OUTPUT CONNECTION
Avtron THIN-LINE II encoders provide an alarm signal if maintenance is required under specific circumstances. An optional internal
alarm LED indicator is also available. Green indicates power on, red indicates alarm on. Following are application examples
provided to help install the alarm output.
Example 1. Alarm output using +V(OUT). +V(OUT) is equal to +V, the encoder power supply.
