It provides a two phase, A Quad B frequency (pulse) output, with complements. The AV mounts on a mm C-Face, also known as a B-Flange. Because the AV is modular, there are no bearings or couplings required. This, combined with the latest magnetoresistive (MR) sensor technology, allows the AV to provide superior mechanical performance and increased reliability. An Avtron AV 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 AV 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). NOTE Special option 00 selects an alternate PPR code defini tion. Example: A-8 PPR with option code 000. A*-70 PPR with option code 00. INSTALLATIONs Refer to the back page of these instructions for outline and mounting dimensions. Axial float or endplay must be less than ±.7mm. In preparation for installing the Model AV 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. Equipment Needed for Installation Provided Optional Not Provided AV Stator/Housing Socket Hd Cap Screw M0 x 0mm (4) AV Rotor Socket Set Screw M4 x mm () or Preinstalled cam screw Thread locker (blue) Extended Shaft Cover w/ Screws - x 0. (4) Lock Washers Thru Shaft Cover w/ V-Ring Seal and Silicone Lubricant Phillips Screwdriver mm Hex Wrench (T-Handle Style for Thru- Shaft Rotors >70mm) mm Hex Wrench 8mm Hex Wrench 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. ROTOR INSTALLATION The motor shaft must project at least mm 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 (A80) and slide the rotor onto the shaft until it is in the proper position as shown in Figure. If a guage is not available, use the stator housing alignment grooves as show in Figure. 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. -.8 N-m (See Figure) using the mm hex wrench. Total cam screw rotation will be less than one turn.

2 ROTATE CAM SCREWS TO LOCK ROTOR TIGHTEN: 0-0 IN-LB.-.8 N-M CW CW FIGURE Jack Screw Holes M the inside of the rotor bore before mounting. Tighten the rotor set screws to N-m using the mm 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 provide enough holding force, and the rotor may slip. ALIGNMENT NOTCH ALIGN ROTOR FACE WITH BOTTOM OF NOTCHES IN HOUSING CAUTION U.S. Patent 7,48, 997 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 lock er to the rotor set screw holes, preferably from STATOR HOUSING INSTALLATION The stator housing is attached to the motor using four socket head cap screws M0 x 0. x 0mm long, locating on a 0mm 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 7 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 ) 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 AV 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. SPECIFICATIONS ELECTRICAL A.

4 COVER INSTALLATION Covers must not interfere with the motor shaft or rotor. The longest shaft that can be used without interfering is 7.mm with a standard flat cover (Cover Style option F ) and.mm with an extended pie pan cover (Cover Style option E ). Through shaft covers with seals are avail able 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 #- x 0." 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 con nected to case ground at the encoder, or grounded as the receiving device, but should not be ground ed on both ends. See note below for Danaher/Northstar wiring. Refer to the wiring diagrams for specific information on each option. The AV 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 (AV mounting end). NOTE Wiring option G provides a pinout compatible with NorthstarTM encoders, with a cable shield connection on pin 0. 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 ) Remove Power. ) Exchange wires on cable, either at encoder cable end, or at speed controller end (but not both). a) Single Ended Phase Wiring (see wiring diagram) Exchange A and B at the use end of the wires. b) Differential 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. ) 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: strand ed copper, through AWG (Industrial EPIC connector type options can use 4 AWG), each wire pair individually shield ed with braid or foil with drain wire,.0 uf of maximum total mutual or direct capacitance, outer sheath insulator. See specifications for maximum cable length. Strand ed AWG wire should not be used for cable runs great er then meters. If 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 AV 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 AV. 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):. Remove the rear cover, and use the built-in gauge to check the location of the rotor (see Figure ). Ensure the label marked This side out is facing away from the motor.. Remove the AV from the motor. Clean the housing mounting surface for the AV housing. Ensure the AV 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 AV and the rotor is properly located, replace the AV sensor. 4

7 An oscilloscope can also be used to verify proper output of the THIN-LINE II 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 ), 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 -00, or use retrofit shielding kits AVSKxxx yy z, where xxx=model (ex: A), yy=rotor (ex: CB), and z=cover (ex: F). NOTE: Do not use rotors from THIN-LINE I (M, MS, M7, M8, M) with AV. This will cause incorrect PPR output, but the AV LED will remain green.
