Optical Alignment

• No interruption can be in the detection zone of the SL-V.

• The surface of the transmitter and the receiver must be clean.

1. Both the transmitter and receiver must be installed facing each other, and by adjusting the angle of

mounting bracket until the green bar LEDs No. 1 to No. 5 are on.
The bar LED indicators and the center indicators show the light reception status of the top and bottom

beam axes. Adjust the misaligned beam axes by observing these indicators.

See "Bar LED Indicator" (page 6-2)

See "Center Indicator" (page 6-6)

2. Alignment must be completed at the center of the angle range in which the bar LEDs No.1 to No. 5

keep lighting green.

3. After completing optical alignment, the screws for the mounting brackets must be secured.

- The recommended tightening torque for standard mounting brackets A, B, C and J is 1 N·m.
- The recommended tightening torque for compact E-to-E mounting brackets and E-to-E mounting

brackets is 1.2 N·m.

- The recommended tightening torque for thin type mounting brackets is 1 N·m.

If all of bar LEDs No. 1 to No. 5 do not light in green even though the optical alignment for the SL-V has been

tried, check the following points:

• At first, try to do the alignment for the top and bottom beam axes.

• The transmitter and receiver are installed at same level to each other.

• The part of machine onto which the transmitter is installed and the other part of machine onto which the

receiver is installed must be fixed and parallel to each other.
