1. Operating
Cautions
• Do not use the unit in places where it may receive excessive shocks. Otherwise the
inside of the unit may be damaged or the unit may become unable to produce normal
output signals.
• Be sure to turn of the power before connecting or disconnecting connectors in order
to prevent damage or misoperation.
• Insert the connector into the counter unit until it locks. Be sure to turn of the power
switch before connecting or disconnecting the connector.
• Locate the measuring unit at least 10 cm away from a strong magnetic source. (h
e
measuring unit must not be used in magnetic i elds exceeding 5 mT.)
• Do not forcibly pull the cable for connecting or disconnecting, or it may cause breakage.
• h
e measuring unit is short circuited to the frame GND (ground terminal) of the
counter unit by shield wire of the cable. When the measuring unit is used with an other
signal processing device on a machine tool, etc., be aware of the ground level.
• Do not place the measuring unit where it is exposed to splash of water or oil.
• When using a vacuum ejector or other device to operate the feeler through the air feed
port, use an air-pass system such as shown in Fig. 1 to enable air driving. h
e optimum
vacuum rate is 0.04 to 0.067 MPa.
• If the spindle ejection speed is too fast, an error may appear on the display the moment
that the workpiece is touched. Excessive impact may dislodge the retainer inside the
bearing, causing the measuring range to be reduced. In this case, use a speed controller
as shown in Fig. 1 to adjust the spindle speed.
• h
e tube used for the air feed port should have an outer diameter of
φ
4 mm.
• Injection of air causes the spindle to perform the retraction operation.
• Use dry air for air injection.
• Calibration is recommended every year.
• h is unit is equipped with an anti-dust bellows on the spindle. Organic solvents,
ozone, ultraviolet rays, and other adverse conditions in the ambient atmosphere can
cause rapid deterioration of the anti-dust bellows. When using in these environments,
replace anti-dust bellows periodically (every six months to one year).
