Operating Precautions
• Th is product is a class 3B (DHHS: IIIb) laser product using a semiconductor laser with a wavelength of 790 nm (5 mW or
less). Users and manufacturers must follow relevant safety standards. Safety measures that comply with class 3B must be
taken in order to use this product.
• Do not look directly into the laser emission areas of the head unit while the power is on. Th is product uses a semiconductor
laser (wavelength: 790 nm). Th e emitted laser beams are hazardous to the human body.
• Never connect or disconnect the connection cable connectors while the power is on. Doing so may cause the sensor light
source to malfunction.
• Take care not to touch the connector pins of the head unit. Doing so may cause malfunction.
• Do not pull at the cable forcibly or bend it excessively. {Bending radius (inside) Static: 50 mm or more, non-operating}
• Th
e functions and performance of this system are not guaranteed when used with other than the head unit, scale unit and
interpolator unit combination provided when shipped from the factory, even if the other devices are the same products.
Always use the provided combination. Th
e combination can be checked by the serial number of each unit. (See section 9
“Dimensions” for the serial number label locations.)
• Use the SET-HD100 approximately 30 minutes aft er power is supplied to the unit, when the temperature of the head unit
reaches a stable state.
• Perform self-calibration regularly when a factor arises that may aff ect accuracy, such as a change in ambient temperature.
• Th
e SET-HD100 is a precision measuring instrument. Handle it with extreme care to avoid applying excessive shocks. For
transport, be sure to pack it in the same way as it was packed at the time of purchase. Also, be sure to always attach the
protective caps to the connectors.
Notes on installation
Take careful note of the following points when installing the system to prevent noise, electromagnetic interference or other
adverse eff ects from other equipment.
• Do not pass the connection cable together with the power line in one duct.
• Provide power from a low-noise power supply.
• Be sure to separate the system by at least 0.5 meters from sources of high voltage, large currents and large power relays.
• Do not use the cable connecting the head unit and the interpolator unit in a location where it may be repeatedly subjected
to a bending force (cable carrier, etc.).
• Establish a reliable connection between the head/interpolator units and a ground. If the ground connection is unstable,
proper performance may not be achieved.
• In the event that a large potential diff erence occurs between the head unit mount, interpolator unit mount, and the frame
ground of a connected device, the product may not operate properly due to current fl owing to the product frame and the
cable shield. Take measures such as connecting a ground to each device such as shown in the fi gure below.

• Wear an antistatic wristband when working to prevent electrostatic damage.
• When installing the head unit, scale unit and other parts, control the tightening torque using a torque wrench.
Uneven or excessive tightening torque may cause the output to drop or result in drift .
[The recommended tightening torque values are as follows]
M6 screw : 1.0 N·m ±0.1 N·m (head unit)
M4 screw : 0.6 N·m ±0.06 N·m (scale unit)
M4 screw : approximately 0.3 to 0.4 N·m (when attaching the scale unit case)
• Use this product in an environment with an ambient temperature of +10°C to +30°C (no condensation).
Do not install it in a location that is exposed to direct sunlight or warm air or near sources of heat such as motors. Th
is
could adversely aff ect the accuracy.
