Operating Cautions; Mounting Instructions - Sony DG805FL Instruction Manual

Operating Cautions

• Insert the connector into the display unit until it locks. Be sure to turn off the
power switch before connecting or disconnecting the connector.
• Locate the probe at least 10 cm/3.94" away from a strong magnetic source.
• Do not pull the cable when mounting or demounting the probe, or the cable may
be disconnected.
• The probe is short circuited to the frame GND (ground terminal) of the display unit by
shield wire of the cable.
When the probe is used with an other signal processing device on a machine
tool, etc., be aware of the ground level.
• Do not place the probe where it is exposed to splash of water or oil.
• In operating the probe DG805FL, 810FL with a vacuum pump, use such an air-
pass system as shown in Fig. 1. The optimum vacuum rate is 40 to 66.7 kPa.
Further, put such an orifice as shown in Fig. 2 on a tube from the air lifter
connector to control the air suction and discharge speed. The measuring feeler
is lifted at the air discharge to the vacuum pump.
• Recommended calibration interval 1 year.

Mounting Instructions

• Except when using a flat feeler, it is recommended to either attach a nominal 2.5
spring washer or use a screw lock to prevent loosening of the feeler
• Use the fitting to be attached to the gauging probe as shown in Fig.3. Especially, the
length of the M4 screw section to be inserted into the gauging probe should be 4.5
mm(0.18") or less. If the screw is too long, the gauging probe may be damaged.
• Fastening torque of the measuring feeler: 0.05 to 0.06 N•m.
