If the alarm output and/or LED indicate a fault (RED):

Remove the rear cover, and use the builtin gauge to check the

location of the rotor (see Figure 1). Ensure the label marked "This side

out" is facing away from the motor.

Remove the AV85 from the motor. Clean the housing mounting

surface for the AV85 housing. Ensure the AV85 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 AV85 and the rotor is properly located, replace

the AV85 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 nonmagnetic material

(aluminum, stainless) (especially shafts). For GE CD frame motors and

similar styles, Avtron offers nonmagnetic stub shafts. If variations

persist, consider replacing the encoder with supershielded 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 AV85 stator housing can be removed by loosening and removing

the socket head cap screws.

CAM SCREW AND END-OF-SHAFT ROTOR REMOVAL

Disengage the (2) cam screws or endofshaft mounting screw(s) 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 ROTER 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.
