CAUTIONS

٨

Make sure that the power supply is off while wiring or adding the units.

٨

Take care that wrong wiring will damage the sensor.

٨

Verify that the supply voltage variation is within the rating.

٨

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.

٨

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.

٨

Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.

٨

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.

٨

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

2

or more, cable. However, in order to reduce noise,

make the wiring as short as possible.

٨

Take care that when the cable is extended, the residual voltage rises.

٨

Do not shorten or lengthen the sensor head cable.

٨

This sensor is suitable for indoor use only.

٨

Do not use the sensor at places having intense vibrations, as this can
cause malfunction.

٨

Take care that the sensor does not come in direct contact with water, oil,
grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.

٨

Make sure that the sensing end is not covered with metal dust, scrap or
spatter. It will result in malfunction.

٨

Take care that stress by forcible bending or pulling is not applied directly
to the sensor head cable joint.

MOUNTING

Be sure to use a sensor head and amplifier as a set.

Mounting of amplifier

٨

How to mount the amplifier

Ԙ

Fit the rear part of the mounting section of the
amplifier on a 35mm width DIN rail.

ԙ

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

Ԙ

Push the amplifier forward.

ԙ

Lift up the front part of the amplifier to remove it.

Take care that if the front part is lifted without pushing the amplifier forward, the

Note:

hook on the rear portion of the mounting section is likely to break.

CASCADING UNITS

٨

Make sure that the power is off while cascading/removing the amplifiers.

٨

Be sure to check the allowable ambient temperature, as it depends on
the number of amplifiers connected in cascade.

٨

In case two, or more, amplifiers are connected in cascade, make sure to
mount them on a DIN rail.

٨

When the amplifiers move on the DIN rail depending on the attaching
condition, fitting them between the optional end plates (MS-DIN-E)
mounted at the two ends.

٨

When connecting in cascade, mount the amplifiers close to each other, fitting
them between the optional end plates (MS-DIN-E) mounted at the two ends.

٨

When connecting more than two amplifiers in cascade, use the sub cable
(CN-71-Cغ) as the quick-connection cable for the second amplifier onwards.

٨

This product does not incorporate the communication function When
this product used by cascading along with other than this product,
mount at the either side of the cascaded products.

Refer to the ' MOUNTING' for mounting/dismantling the amplifiers.
