Installation

J CAUTION

Item

Examples

Power Supply

Do not impose an excessive voltage on the E2EL, otherwise it

may explode or burn.

Do not impose 24 VAC on any E2EL model, otherwise it may

explode or burn.

Load short--circuit

Do not short--circuit the load, or the E2EL may explode or burn.

The E2EL’s short--circuit protection function is valid, if the polarity

of the supply voltage imposed is incorrect and within the rated

voltage range.

Wiring

Be sure to wire the E2EL and load correctly, otherwise it may

explode or burn.

J CORRECT USE

Installation

Power Reset Time

The Proximity Sensor is ready to operate within 100 ms after

power is supplied. If power supplies are connected to the

Proximity Sensor and load respectively, be sure to supply power

to the Proximity Sensor before supplying power to the load.

Power OFF

The Proximity Sensor may output a pulse signal when it is turned

off. Therefore, it is recommended to turn off the load before

turning off the Proximity Sensor.

Power Supply Transformer

When using a DC power supply, make sure that the DC power

supply has an insulated transformer. Do not use a DC power

supply with an auto--transformer.

Sensing Object

Metal Coating:

The sensing distance of the Proximity Sensor vary with the metal

coating on sensing objects.

Wiring

High- tension Lines

Wiring through Metal Conduit

If there a power or high--tension line near the cord of the

Proximity Sensor, wire the cord through an independent metal

conduit to prevent against Proximity Sensor damage or

malfunctioning.

Core Tractive Force

Do not pull cords with the tractive force exceeding the following:

pull force (N) = 20 x cable diameter ( mm)

Mounting

The Proximity Sensor must not be subjected to excessive shock

with a ha mmer when it is installed, otherwise the Proximity

Sensor may be damaged or lose the water--resistivity.

Environment

Water- Resistivity

Do not use the Proximity Sensor underwater, outdoors or in the

rain.

Operating Environment

Be sure to use the Proximity Sensor within operating ambient

temperature range and do not use the Proximity Sensor outdoors

so that its reliability and life expectancy can be maintained.

Although the Proximity Sensor is water resistive, a cover to

protect the Proximity Sensor from water or soluble machining oil

is reco mmended so that its reliability and life expectancy can be

maintained. Do not use the Proximity Sensor in an environment

with chemical gas (e. G., strong alkaline or acid gases including

nitric, chromic, and concentrated sulfuric acid gases).
