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

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

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, 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.

MOUNTING

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

Mounting of amplifier

How to mount the amplifier

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

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.

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.

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

Note:

Take care that if the connector is pulled out without pressing the projection, the projection may break. Do not use a sensor head connector whose projection has broken. Furthermore, do not pull by holding the cable, as this can cause a cable-break.

٨ Mounting of sensor head

CASCADING UNITS

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

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

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

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.

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.

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.

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.

Cascading method

Mount the amplifiers, one by one, on the 35mm width DIN

Sub-cable (CN-71-Cغ) (optional)

and set them close to each other without any gap between them.

Connect the quick-connection cables to the amplifiers.

Mount the end plate (MS-DIN-E) (optional) at both ends to hold the units between their flat sides.

Tighten the screws to fix the
