Apply anti-seize compound to the shaft.CAUTIONDo not strike the encoder or rotor at any time. Damagewill result and the warranty will be void. At installation,clean and remove paint and burrs from motor shaft andmounting face. Apply anti-seize compound (supplied) toeach EXCEPT CAM SCREW ROTORS.NOTEIf optional inboard seal plate and/or magnetic shield isused, gage the rotor location from the shield/seal plate(s).Ensure the rotor label marked “this side out” is facingaway from the motor.GENERALThe Avtron Model SV850 SAFETach™ III is an incremental encoder (alsoknown as tachometer or rotary pulse generator), allowing operationdown to zero RPM. It provides a specific number of electrical Pulses PerRevolution (PPR) that are proportional to a shaft’s revolution. The SV850SAFETach III is a bearingless, couplingless, modular design, providingunequaled reliability and mechanical performance in a functional safetyenviroment.The SV850 fits AC and DC motors with an 8.5” C (FC / 180) Face. Bothend-of-shaft and through shaft mountings are accommodated.The SV850 Encoder consists of three or four parts: a rotor, a statorhousing, and one or two removable sensor modules. No gapping,adjustment, or shimming is required!An Avtron SV850 SAFETach III is equipped with one or two SV5 sensormodules. Each module has a two-phase output (A, B) 90° out of phase,with complements (A, B), (A Quad B Output), and a marker pulsewith complement (Z, Z). For applications which require more than 2independent outputs, SV850 encoders may be stacked via the use ofshaft adapters (see Table 2 for part numbers). Two separate encoderswould be purchased.Output resolution on the SV850 is determined by the sensor only. Unlikeolder models, any PPR’s can be mixed and matched. Selection of therotor is based only on the shaft mounting requirements (and not PPR).The SV5 removable sensor assembly has a diagnostic package thatincludes Adaptive Electronics and a Fault-Check output. With thispackage, the SAFETach III can maintain itself, and let you know if there isa problem before the problem causes unscheduled downtime.SECTION II: INSTALLATIONGENERALThe motor must comply with NEMA MG1 for dimensions, face runout, andshaft runout. Axial float or endplay must be less than +/-0.100” inch.INSTALLATION HARDWAREInstallation hardware required is attached to each assembly.Equipment needed for installationThe outer edge of the rotor may be damaged by scratches, severe blows,and strong magnetic fields.Equipment Needed for InstallationProvided Optional Not ProvidedSV850 Encoder- Washer, Spring Lock1/2 (4)- Hex Hd.
