MOUNTING

How to mount the amplifier

ԘԙFit 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

ԘԙPush 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

Note:

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

How to mount the sensor head

ԘԙInsert the sensor head connector into the inlet until it

clicks. Fit the cover to the connector.

CAUTIONS

Make sure that the power supply is off while wiring.

Verify that the supply voltage variation is within the rating.

Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the sensor may get burnt or damaged.

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.

The ultra long distance (U-LG) mode is more likely to be affected by extraneous noise since the sensitivity of that is higher than the other modes. Make sure to check the environment before use.

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.

Take care that short-circuit of the load or wrong wiring may burn or damage the sensor.

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.

Make sure to use the optional quick-connection cable for the connector type LS-401(P).

Extension up to total 100m is possible with 0.3mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

This sensor is suitable for indoor use only.

Avoid dust, dirt, and steam.

Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.

This sensor cannot be used in an environment containing inflammable or explosive gases.

Never disassemble or modify the sensor.
