ROTOR INSTALLATION
Use the dial indicator gauge to ensure motor shaft runout (TIR) does not
exceed (0.004”) [0.10mm]. Apply anti-seize compound to the shaft.
CAUTION
Do not strike the encoder or rotor at any time. Damage
will result and the warranty will be void. At installation,
clean and remove paint and burrs from motor shaft and
mounting face. Apply anti-seize compound (supplied) to
each EXCEPT CAM SCREW ROTORS.
NOTE
If optional inboard seal plate and/or magnetic shield is
used, gage the rotor location from the shield/seal plate(s).
Ensure the rotor label marked “this side out” is facing
away from the motor.
GENERAL
The Avtron Model SV850 SAFETach™ III is an incremental encoder (also
known as tachometer or rotary pulse generator), allowing operation
down to zero RPM. It provides a specific number of electrical Pulses Per
Revolution (PPR) that are proportional to a shaft’s revolution. The SV850
SAFETach III is a bearingless, couplingless, modular design, providing
unequaled reliability and mechanical performance in a functional safety
enviroment.
The SV850 fits AC and DC motors with an 8.5” C (FC / 180) Face. Both
end-of-shaft and through shaft mountings are accommodated.
The SV850 Encoder consists of three or four parts: a rotor, a stator
housing, 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 sensor
modules. Each module has a two-phase output (A, B) 90° out of phase,
with complements (A, B), (A Quad B Output), and a marker pulse
with complement (Z, Z). For applications which require more than 2
independent outputs, SV850 encoders may be stacked via the use of
shaft adapters (see Table 2 for part numbers). Two separate encoders
would be purchased.
Output resolution on the SV850 is determined by the sensor only. Unlike
older models, any PPR’s can be mixed and matched. Selection of the
rotor is based only on the shaft mounting requirements (and not PPR).
The SV5 removable sensor assembly has a diagnostic package that
includes Adaptive Electronics and a Fault-Check output. With this
package, the SAFETach III can maintain itself, and let you know if there is
a problem before the problem causes unscheduled downtime.
SECTION II: INSTALLATION
GENERAL
The motor must comply with NEMA MG1 for dimensions, face runout, and
shaft runout. Axial float or endplay must be less than +/-0.100” inch.
INSTALLATION HARDWARE
Installation hardware required is attached to each assembly.
Equipment needed for installation

STATOR HOUSING INSTALLATION
The stator housing is retained to the motor using four, 1/2-13 x 3” bolts
and spring type lock washers (supplied). If the stator is to be sandwich
mounted between an accessory such as a brake and the motor, select the
bolt length accordingly. Apply anti-seize compound to the perimeter of the
SV850 where it will contact the motor C-face.
Carefully move the stator housing into position, avoiding contact with the
rotor. DO NOT FORCE the housing into place. Install the four mounting
bolts (torque 30 to 35 foot pounds) [47.5-40.6 n-m].
THROUGH SHAFT APPLICATIONS (Rotors KA-K9)
1. The through-shaft must project at least 1.5” [38.1mm] from
the accessory mounting face. If it is greater than 2” [50.80mm]
long, use the outboard through-shaft cover, detailed in Figure 4.
2. Slide the rotor on the shaft (option “B” or “T”), ensuring the
rotor label “this side out” is away from the motor and shaft key
engages keyway in rotor. The space
between the mounting face and the rotor must be set to
0.584” [14.83mm], as shown in Figure 2. Use Avtron gauges
(A35226 or A25355) or housing alignment grooves as shown
in Figure 5 to verify position. (Note: if optional inboard seal or
shield plate is used, gage the rotor location from the seal
shield plates. See Figure 3.) Turn the cam screw of the rotor in
the directions shown on the rotor to engage the cams. Tighten
to 9-10 ft-lb (12.3- 13.5 n-m). Total cam screw rotation will
be less than one turn.
FIGURE 2
ROTOR MOUNTING
(Through Shaft Shown)
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. Do apply anti-seize compound
(copper) to the encoder face to assist in easy removal.
The SV850 electronics are fully sealed; water may enter
and leave the rotor area as needed. Remove the bottom
pipe plug in the housing if frequent moisture buildup is
expected.
(OPTIONAL) OUTBOARD SEAL PLATE KIT
INSTALLATION.
For applications requiring shafts to pass completely through the SV850,
Avtron offers an outboard through-shaft seal plate kit with V-ring seal. See
Table 4 for part numbers and Figure 4.
1. Install the encoder rotor as shown above.
2. Remove the existing cover of the encoder. Retain the screws
and washers.
3. Mount the SV850 stator housing as shown in Figure 4.
4. Install new through-shaft cover using the (4) #10-24 screws
and washers from step 2.
5. Apply silicone lubricant or medium grade machine oil (20
weight) to the outboard side of the cover where the V-ring seal
will contact it.
6. Slide the V-ring seal onto the shaft, and ensure that it is
compressed against the cover. See installation Figure 4.
(OPTIONAL) CHECK ROTOR POSITION
1. Remove a sensor or blank side cover plate.
2. Verify the rotor magnetic stripe is aligned with the grooves (see
Figure 5).
3. Replace the sensor or side cover plate.
WIRING INSTRUCTIONS
CAUTION
Remove power before wiring.
Wiring diagrams are shown in Figure 6 and 7.
For bidirectional operation of the encoder, proper phasing of the two
output channels is important. Phase A channel leads phase B channel for
clockwise shaft rotation as viewed from the anti-drive or accessory end
of the motor (encoder mounting end). Wiring option “G” provides a pinout
compatible with Northstar™ 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 Ain the phase A pair OR B with Bin 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 in Figure
6 are based on typical applications. Refer to the system drawing for
specific cable requirements where applicable.
Physical properties of cable such as abrasion, temperature, tensile
strength, solvents, etc., are dictated by the specific application.

SV850 SAFETach™ III Incremental Encoder 4Rev: 001
General electrical requirements are: stranded copper, 22 thru 16 gauge
(Industrial EPIC Connector options can use 14-20 AWG), each wire pair
individually shielded with braid or foil with drain wire, 0.05 uF maximum
total mutual or direct capacitance, outer sheath insulator, 1,000 ft. max.
See WIRE SELECTION CHART in Figure 6 for some suggested cables.
See Figure 7 for examples of alarm output wiring.
NOTE
When using the industrial connector (“G”, “P” options),
the minimum wire size is 20 gage, and 20 gage (only) wire
ends must be tinned with solder before connection at the
screw terminals.
MAINTENANCE
GENERAL
This section describes routine maintenance for the Avtron SV850 Encoder.
For support, contact field service for Avtron Encoders at
216-642-1230. For emergency after hours service contact us at
216-641-8317. The SV850 SAFETach III circuitry includes a diagnostic
package that includes Adaptive Electronics and a Fault-Check output.
ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose “high” and “low”
conditions are of the same duration (50%/50%). The SV850 adaptive
electronics extends the life of the SV850 by constantly monitoring and
correcting duty cycle over time.
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 SV850 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 SV5 sensor module. If the new module shows
GREEN, and the drive still shows encoder loss/tach fault, then the wiring is
faulty and should be repaired or replaced.
WARNING
Only use SV5 sensors in SV850 Encoders. Use of other
sensors will not retain the functional safety compliance of
the SV850.
If the alarm output and/or LED indicate a fault (RED):
1. Remove a sensor plate or one of the sensors, and use
the built-in gauge to check the location of the rotor (see Figure
2.1). Ensure the label marked “This side out” is facing away
from the motor.
2. Remove the SV5 sensor from the housing. Clean the housing
mounting surface for the SV5 sensor and the SV850 housing.
Ensure the SV5 sensor is directly mounted on the SV850
housing, with no sealant, gasketing, or other materials, and
that it is firmly bolted in place.
If the alarm output and/or LED indicate a fault (RED) on a properly
mounted SV5 sensor and the rotor is properly located, replace the SV5
sensor.
An oscilloscope can also be used to verify proper output of the SV850
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 9), 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) (shafts, etc). For GE CD frame motors and similar styles, Avtron
offers non-magnetic stub shafts (included with all “U” style rotor kits).
If variations persist, consider replacing the sensors with super-shielded
models, option -004.
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 may 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.
STATOR HOUSING REMOVAL
To remove the stator housing remove the qty 4 1/2 13 x 3” bolts holding
the housing to the motor.
CAUTION
Take care that the housing does not fall from the pilot and
cause the sensors to crash into the rotor. Damage to the
sensor or rotor could result.
ROTOR REMOVAL
Remove shaft rust and burrs before removing the rotor.
THROUGH-SHAFT AND UNIVERSAL (KA-K9):
Loosen the set or cam screws holding the rotor to the shaft. The cam
screws rotate less than one turn to disengage the shaft. The stub shaft
adapter from the universal (Ux) rotors can be left in place.
NOTE
Do not remove the cam screws from the rotor.
Remove the rotor by hand, taking care not to damage the outer
magnetized ring.
If the rotor cannot be removed by hand, use a gear puller taking care not
to damage the outer magnetized ring.
DO NOT APPLY HEAT TO THE ROTOR. ROTOR ALIGNMENT GROOVE
