2 CAUTIONS
Make sure that the power supply is off while wiring or adding the units.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
In case noise generating equipment (switching regulator, inverter motor,
etc.) is used in the vicinity of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
If power is supplied from a commercial switching regulator, ensure that
the frame ground (F.G.) terminal of the power supply is connected to an
actual ground.
Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
Be sure to use the optional quick-connection cable for amplifier
connection. Furthermore, extension up to 100m (50m: 5 to 8 units are
connected in cascade, 20m: 9 to 16 units are connected in cascade) is
possible with 0.3mm
make the wiring as short as possible.
Take care that when the cable is extended, the residual voltage rises.
Do not shorten or lengthen the sensor head cable.
This sensor is suitable for indoor use only.
Do not use the sensor at places having intense vibrations, as this can
cause malfunction.
Take care that the sensor does not come in direct contact with water, oil,
Spatter-resistant type
GH-F8SE grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.
Make sure that the sensing end is not covered with metal dust, scrap or
spatter. It will result in malfunction.
Take care that stress by forcible bending or pulling is not applied directly
to the sensor head cable joint.
3 MOUNTING
Be sure to use a sensor head and amplifier as a set.
Enclosure:
Mounting of amplifier
SUS303
How to mount the amplifier
Sensing part:
Fluorine resin
Fit the rear part of the mounting section of the
amplifier on a 35mm width DIN rail.
55g approx.
Press down the rear part of the mounting section
of the unit on the 35mm width DIN rail and fit the
front part of the mounting section to the DIN rail.
How to remove the amplifier
Push the amplifier forward.
Lift up the front part of the amplifier to remove it.
Note: Take care that if the front part is lifted without pushing the amplifier forward, the
hook on the rear portion of the mounting section is likely to break.
Connection of sensor head
Connection method
Insert the the sensor head connector into
the connector inlet till a click is felt.
Fit the cover on the connector.
Disconnection method
Pressing the projection on the sensor
head connector, pull out the connector.
Note: Take care that if the connector is pulled out without pressing the projection, the pro-
jection may break. Do not use a sensor head connector whose projection has bro-
ken. Furthermore, do not pull by holding the cable, as this can cause a cable-break.
Mounting of sensor head
Mounting with a set screw
The tightening torque
for mounting should be
as given right.
Furthermore, be sure
to use a set screw with
a cup-point end.
Note: Do not tighten it with excessive strength.
Influence of surrounding metal
The surrounding metal
will affect the sensing
performance. Keep the
minimum
specified in the table
right.
