OMRON ZX2-LD100 (01) PDF MANUAL

Do not expose your eyes to the laser radiation either directly (i.e., after reflection from a mirror or shiny surface). Loss of sight may possibly occur in case of the exposure to laser high power density.

Do not disassemble the product. Doing so may cause the laser beam to leak, resulting in the danger of visual impairment.

When using a device equipped with the ZX2-LD in the U.S., attach an FDA certification label on the sensor at the correct location, and replace the explanatory label with the corresponding Laser explanatory label (English).

When Usage of ZX2-LD in countries other than Japan, U.S. and China, replace the explanatory label with corresponding Laser explanatory label (English).

Please observe the following precautions for safe use of the products:

(1)Installation Environment

Do not use the product in environments where it can be exposed to inflammable/explosive gas.

To secure the safety of operation and maintenance, do not install the product close to high-voltage devices and power devices.

(2)Power Supply and Wiring

Use only products that have been made expressly for the Controller.

High-Voltage lines and power lines must be wired separately from this product. Wiring them together or placing them in the same duct may cause induction, resulting in malfunction or damage.

Always turn off the power of the unit before connecting or disconnecting cables.

(3)Installation

Make sure to tighten all installation screws securely (tightening torque: M3, 0.5 N·m).

(4)Other Rules

Do not attempt to disassemble, deform by pressure, incinerate, repair, or modify this product.

When disposing of the product, treat as industrial waste.

If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or smoke, immediately stop using the product, turn off the power, and consult your dealer.

Please observe the following precautions to prevent failure to operate, malfunctions, or undesirable effects on product performance:

(1)Do not install the product in locations subjected to the following conditions:

• Surrounding air temperature outside the rating

• Rapid temperature fluctuations (causing condensation)

• Relative humidity outside the range of 35 to 85%

• Presence of corrosive or flammable gases

• Presence of dust, salt, or iron particles

• Direct vibration or shock

• Reflection of intense light (such as other laser beams, electric arc-welding machines, or ultra-violet light)

• Direct sunlight or near heaters

• Water, oil, or chemical fumes or spray, or mist atmospheres

• Strong magnetic or electric field

(2)Power Supply and Wiring

Use only products that have been made expressly for the Controller.

To extend the cable from the sensor head, an optional extension cable (ZX2-XCR) must be used.

(3)Warming Up

After turning on the power supply, allow the Controller to stand for at least 10 minutes before use. The circuits are unstable immediately after the power supply is turned on and attempting measurement may result in inconsistent measurement values.

(4)Maintenance and inspection

Always turn off the power of the unit before connecting or disconnecting cables.

Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the sensor.

If considerable foreign matter or dust collects on the front of sensor, use a blower brush (for camera lenses) to blow off the foreign matter. Avoid blowing it off with your breath. For a small amount of foreign matter or dust, gently wipe with a soft cloth. Do not wipe hard. If the surface is damaged, false detection may result.

(5)Sensing Object For Reflective Type Sensor Head

The product cannot accurately measure the following types of objects: Transparent objects, objects with an extremely low reflective sensor ratio, objects smaller than the spot diameter, objects with a large curvature, excessively inclined objects, etc.

Set scaling regularly to maintain accurate detection.

(6)Mutual interference

Inserting a calculation unit between amplifier units can prevent mutual interference between sensor heads. However, this may not work efficiently if Amount of light received of one sensor head is saturated because of the luster of work-pieces and a laser beam of the other sensor head is input. If you are interested in installing a calculation unit in order to prevent mutual interference, carry out a test using the actual system beforehand.

The specifications for the ZX2-LD sensor head are as follows:

F.S.: Full scale of measurement

(*1)Beam diameter: Value of minimum diameter in measuring range. The typical value at the measuring center distance is shown. Defined as 1/e² (13.5%) of the center intensity. The beam diameter may sometimes be affected by the ambient condition of the object such as leaked light from the main beam.

(*2)Resolution: Fluctuation width of linear outputs when connected to Amplifier Unit (With response time set to 128ms and the standard work (white ceramics) placed at the measuring center distance) This value is repetition accuracy of the static condition work, and not distance accuracy. In a strong electromagnetic field, the performance of resolution might not be able to be satisfied.

(*3)Linearity: The error in relation to the ideal displacement output straight line when the standard work is measured.

(*4)Temperature characteristic: Value obtained when the sensor and object (standard work) are fixed with an aluminum jig. (Measured at the measuring center distance)

Fix the Reflective type sensor head with screws (M3). Tightening torque: M3, 0.5Nm.

When mounting a Sensor Head, take care not to touch the emitter and receiver. Adhesion of finger marks may hinder correct measurements. If you have touched them, wipe them with a clean soft cloth.

A ferrite core (supplied with the sensor head) must be attached to the sensor cable. The ferrite cores can be connected within 100 mm from the sensor.
