Thank you for purchasing the SIN-COS photoelectric encoder developed
by Weton.
The SC53 SIN-COS photoelectric encoder produces sine waves. Through
the changes of sine and cosine waves, the subdivided voltage can be
obtained. Then, output signals of the encoder is subdivided as required to
improve resolution. The SC53 SIN-COS photoelectric encoder adopts the
new-type conical shaft and expanders for easy xture. This further simpli-
es the motor control system structure. The SC53 SIN-COS photoelectric
encoder is applicable to elevators, servos, machine tools, and automatic
control equipment. It is mainly applied to control systems of permanent
magnet synchronous elevators.
Before using the encoder, read this guide thoroughly.

■Installation and Uninstallation Description
☞Installation diagram
1) Remove the front cover of the encoder. The conical shaft is displayed, as shown in Figure 3-3.
2) Put the encoder into the location hole of the traction machine until the conical shaft is stuck. Put the M5*50 inner
hexagon screw through the center hole of the conical shaft, and tighten the screw into the hole of the traction machine.
The required tightening torque is 5 N·m to 5.5 N·m. Ensure that the conical shaft and hole are concentric, as shown in
Figure 3-4.
3) Tighten the screw clockwise to x the expander. The required tightening torque is 0.6 N·m to 0.8 N·m. Ensure that the
expander is tightened properly, as shown in Figure 3-5.
4) Install the front cover of the encoder. The installation is complete, as shown in Figure 3-6.
Figure 3-3 Figure 3-4 Figure 3-5 Figure 3-6
☞Uninstallation diagram
1) Remove the front cover of the encoder. The conical shaft is displayed, as shown in Figure 3-7.
2) Unscrew the screw counterclockwise to loosen the expander, as shown in Figure 3-8.
3) Unscrew the M5*50 screw counterclockwise for two to three turns. Then, screw the M10*20 screw clockwise into the
center hole of the conical shaft to jack up the M5*50 screw until the conical shaft leaves the hole, as shown in Figure 3-9.
4) Back off the M10*20 screw and the M5*50 screw in sequence. Then, take off the encoder, as shown in Figure 3-10.

4. Cable Shielding
1) Connect the shielded cable to the ground through the housing of the encoder.
2) Before removing the shielded cable from the traction machine, remove the housing cover, and isolate the
grounded shielding ring and the encoder housing, as shown in Figure 4-1.

☞Safety Instructions
◆If the stall occurs, the encoder may be installed improperly. Remove the
encoder and install it again.
◆Connect cables by strictly following the wiring list to access only correct
signals, avoiding encoder failures.
◆When pushing the encoder into the hole of the traction machine, ensure
that the conical shaft and hole are concentric.
◆The encoder is a precise optical component. Therefore, avoid knock,
beat, and collision during installation and uninstallation.
◆To avoid interference, do not connect the encoder cables in the
same trunking with the power cable. The shielded cable must be well
grounded. If the grounding is unreliable onsite, take out the shield short-
circuiter.
