This indicator illuminates whenever the object is absent for through-beam type and when the object is present for diffuse reflective type. 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. 8 Discontinued Mar. 30, 2009; Use E3Z-L Laser E3L E3L 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.
