Operation

■LIGHT INCIDENT INDICATOR

The LIGHT incident indicator (red LED) illuminates when the

light from the emitter is incident on the receiver and exceeds

the operating level (trigger point) of the sensor. This indicator

illuminates whenever the object is absent for through-beam

type and when the object is present for diffuse reflective type.

Stability indicator

(green LED)

Light incident indicator

(red LED)

■STABILITY INDICATOR

The STABILITY indicator (green LED) illuminates when the

control output is in a stable OFF or ON state. A "stable" state

occurs when the receiver element of the sensor receives less

than 80% (OFF state) or more than 120% (ON state) of

incident light needed to operate the sensor.

The control output STABILITY indicator goes off every time the

amount of light incident on the receiver is within 20% of the

amount of light needed to change the control output state.

The unstable control output condition may occur when the

sensor encounters the leading and trailing edges of the object

to be detected. However, the alarm output described later will

not operate if the unstable condition recovers within 100 ms.

The condition can occur when a change in sensor position,

atmosphere (dust contamination), temperature or ambient light

causes the light incident on the receiving element to be near

the operating level of the sensor.

■ALARM OUTPUT (-50 models)

The alarm output operates when the control

output is in an unstable OFF or ON state for

more than 100 ms. An unstable state occurs

when the amount of light incident upon the

receiver is within 20% of the amount of light

needed to change the control output state.

The alarm output feature indicates gradual

degradation of stability caused by changes in

sensor position, atmosphere, temperature or

ambient light that will eventually result in an

unstable control output. A change that occurs in

less than 100 ms will not cause the alarm

output to operate.

A 100 ms time delay is built into the alarm

output circuit. This prevents false triggering of

the alarm output as the leading and trailing

edges of the object to be detected are sensed.

When sensing objects moving at low speeds, a

separate ON-delay timer should be used to

prevent false triggering of the alarm output.

Precautions

■STATIC ELECTRICITY

When handling the device, special care should be taken to avoid static electricity, as any static discharge can damage the laser diode

element of E3L photoelectric sensor.

■LASER REGULATIONS

The E3L laser photoelectric sensor is intended for use as an

element incorporated into a larger system.

The E3L laser photoelectric sensor meets the standards

required by the Food and Drug Administration (FDA) in the

United States. OMRON has had also reported to the Center

for Devices and Radiological Health (CDRH). The report

includes the condition that the unit is to be used as a part of a

larger system.

Labels (FDA Regulations)

For products sold in North America, attach the following FDA

safety labels for the appropriate sensor body proir to use.

Some or all of these labels may already be attached.

■MAINTENANCE

The E3L laser photoelectric sensor contains no user-

serviceable parts. Refer all servicing to an authorized

OMRON agent.

These devices generate Class I or Class II laser radiation.

Avoid looking at the beam for prolonged periods.

Note: For more information on laser safelt and requirements,

please see Omron's Measurement Sensors Catalog.

Do not disassemble the unit. Users expose themselves to

the risk of laser radiation if they disassemsble the device,

or use it for any purpose other than those described in this

data sheet or in the instruction sheet provided with the unit.
