For orrect Use e sure to follow the instructions in the operation manual provided for correct use of the product. This sensor cannot be used as a press safety device or other safety device for protection of human body that requires conformity to domestic or overseas standards or certification concerning protection of human body. Use for such purposes may lead to death or serious injury in the unlikely event of failure. This sensor is intended for detection of ingress of human body or object passing through an arbitrary point not involving protection of human body or safety. When using this sensor for safety purposes, ensure safe operation of the system as a whole including detection and control. Using Operation Indicator as Work Instruction Indicator Input a flicker signal as a no-voltage contact or NPN transistor open collector input shown as the dotted line in the connection diagram. The indicator blinks in step with the cycle (both transmitter and receiver flicker). When light beam of any axis is blocked, the operation switches to the illuminated state as the operation indicator. Sensor Installation Orientation When installing the sensor, make sure that the ends of the transmitter and receiver with the cord are oriented either upward or downward. The sensor does not function if the transmitter and receiver are not oriented the same way. Sensor Light received Light blocked Indicator ontrol input ON OFF Indicator Operation Illuminated Not illuminated link ontinuous illumination End with cord End with cord Output Operation ON OFF The tightening torque for installing the sensor (with M4 screws) should not exceed 0.

Indicators Indicator operation Name olor Description Power indicator Green Illuminated when power is supplied Operation indicator Red Illuminated when the sensor is activated (light beam of any axis is blocked), turned off when light beams of all axes are received Stable light reception indicator Green Illuminated when the received light intensity level is 1% or more of the operation level Operation indicator Red Illuminated when the sensor is activated (light beam of any axis is blocked), turned off when light beams of all axes are received Indicator arrangement Installation Location ny reflecting object (wall, floor, machine, etc.) within the effective range between the transmitter and receiver may allow the light of the sensor to go around the detection object, which is supposed to block the light, and reach the receiver. hoose the installation location carefully (any glossy object such as stainless steel in the surrounding area must be at least 0 mm away from the center of the light transmission and reception area both vertically (up and down) and horizontally (left and right). Wall, floor, machine, etc. Power indicator (green) Stable light reception indicator (green) shows operation indicator (red); 4 lamps for each unit Irregularly reflected light The operation indicator for ESN-T consists of two lamps (top and bottom). Detection object utomatic sensitivity compensation feature fter the light axis alignment is completed, turn the power off once and back on. The automatic sensitivity compensation feature is enabled and the sensitivity is set at the optimum for the sensor. If the lens is soiled with dirt or dust, the sensitivity is automatically compensated to achieve the optimum sensitivity after the soil is removed.
