Connection
●
Turn off the power of controller before connecting or disconnecting the connec-
tors.
●
When connecting or disconnecting the connectors, be sure to hold the connector
area not to apply extra force to the cable.
●
Be careful not to touch terminals or to let foreign matter get in the connector after
disconnecting connectors.
●
Be careful not to apply force to around the connector of standard cable and ex-
tension cable. Do not bend the cables near connectors. Failure to do so causes
causes disconnection of the cable.
●
When moving the sensor head during operation, install it so the cable not bend
bend during movement. Use replaceable extensions cable in case the cable
needs bend.
Wiring
●
Do not run the sensor cable along (bundled in parallel) with other wirings. Keep it
at least 100mm away from other wires. Run the cable so it is separate from high
voltage and power circuit lines. If it is necessary to run the cable in parallel with
them, shield it by running through a grounded electrical conduit.
●
Install the product as far away as possible from noise source such as high-voltage
lines, high-voltage device, power lines, power device, machines which generate a
large starting and stopping surge, welding machines and inverter motor.
●
Do not pull the cable using a force more
than 29.4N when routing the cable with
the sensor head and controller fixed. At
least 20 mm is required from the cable
connection to the bend. The bending
radius must be 30 mm or more.
●
Use only 1 extension cable for connec-
tion between one sensor head and a
controller.
20mm or more
R30mm or more
Warming up time
●
Allow at least 30 minutes of warming up after turning on the power to ensure the
performance of the product.
Environment
●
The life of the semiconductor laser depends on the ambient temperature during
use. When using the product near a heat source, take measures to lower the am-
bient temperature of the sensor head as possible. Mount the sensor on a device
having good heat radiation because the sensor itself emits heat.
● Water, oil, or fingerprints on the emitter surface and receiver surface of sensor
head reflects light. Dust and dirt on them block light. Keep them clean at all times.
When cleaning these parts, wipe them off using a soft lint-free cloth or lens clean-
ing paper.
●
Install the sensor head so ambient light such as sunlight or light with the same
wavelength as laser beam should not enter the light receiver. If high accuracy is
required, install a light shielding plate or the like on the sensor head.
●
The controller and connectors are not structurally dustproof, waterproof, or corro-
sion-resistant. Do not use the product underwater or in the rain.
● Do not use the product in dusty places or that exposed to flammable or corrosive
gases, droplet, direct sunlight, severe vibration or impact.
Setting
● The product is used at specular reflection installation. Set the “Installation Mode”
to Specular Reflection.
Note: The initial values of “Analog Scaling” after initialization is set to the following values when the sensor head is
connected to the controller of Version 1.1* or earlier.
Measurement Value A +1.000000[mm], Correction Value a +1.000[V]
Measurement Value B -1.000000[mm], Correction Value b -1.000[V]
The initial values of “Analog Scaling” at initialization is +5.000[V] for Correction Value a and -5.000[V] for Correc-
tion Value b when the sensor head is connected to the controller of Version 1.2* or later.
