Optical Axis Alignment
When the optical axis alignment indicators [ALIGNMENT] of transmitter, receiver and
amplifier do not light even if the sensor head is installed and turned on, align the optical
axis of the sensor head.
Move the attaching angle of the transmitter and receiver while the target is not
present within the measurement range. Then fix the transmitter and receiver near the
center of the range where the optical axis alignment indicators [ALIGNMENT] light
up.
Reference If the mounting distance between the transmitter and receiver is as follows, the
optical axis alignment is not necessary when mounting within the "parallel
acceptable range" and "tilt acceptable range".
• IG-010: 3 to 500 mm
• IG-028: 50 to 500 mm
