Z4D-F Z4D-F Nomenclature ■ Analog Output (Z4D-F04A) (1) (2) (1) Power (PWR) Indicator The green PWR indicator is lit when power is properly supplied to the Sensor. (2) Alarm (ALM) Indicator The red ALM indicator is lit if there is no sensing object or the reflectivity of the sensing object is low and it is impossible for the Sensor to process the light reflected to the Sensor. The indicator is lit when the amount of light is less than what is required for computation by the Sensor. When the ALM indicator is lit, make necessary adjustments so that the indicator turns OFF. Appropriate amount of light: Insufficient amount of light: ■ Not lit Lit in red ON/OFF Output (Z4D-F04D) (3) (4) (5) (3) Stability (STB) Indicator The green STB indicator is lit when the Sensor is receiving sufficient light to process. If the indicator is not lit, adjust the amount of light to turn on the indicator. (4) Operation (OPE) Indicator The Sensor is synchronized with the ON/OFF output and the orange OPE indicator is lit when the Sensor has ON output. (5) Distance Adjustor The ON/OFF position can be set with the distance adjustor if a sensing object is at the sensing range (i.e., 4±1.25 mm). The ON/ OFF position will shift farther from the Sensor if the distance adjustor is turned clockwise and the ON/OFF position will shift closer to the Sensor if the distance adjustor is turned counterclockwise. 5 Z4D-F Z4D-F Operation ■ Connections/Output Circuits Analog Output Signal processor Connector (Brown) (Black) 12 to 24 VDC 0 to 6.5 V Output (Blue) 0V NPN Open Collector Output Signal processor Connector (Brown) Load Output (Black) (Blue) 6 12 to 24 VDC 0V Z4D-F Z4D-F Dimensions ■ Z4D-F04A Operation indicator Stability indicator Mounting Holes Two, M3 Mounting holes Mounting bracket can be attached to this side.

For details about the K3TX, refer to the K3TX Datasheet. 4. The diagram shown here is for a K3TX model with DC power specifications. When using a K3TX with AC power specifications, separate the AC power supply to the K3TX from the DC power supply to the Z4D-F04A. 8 Note: Reverse operation is possible with the signal input selector of the S3D2.

Load Incorrect Brown +12 to 24 V Sensor Black 0V Blue 9 Z4D-F ■ Z4D-F Correct Use Mounting Z4D-F04A Install the Sensor so that the optical axis of the Sensor and the surface of the object meet at right angles (i.e., the panel that incorporates the light source is parallel with the object). For accurate results, it is recommended that the sensing distance is set to the measurement point (4 mm). Analog Output The Z4D-04A has an output of 3 V if a sensing object is located at the standard distance (i.e., 4±0.3 mm). The output decreases if the sensing object is closer to the Sensor and the output increases if the sensing object is farther from the Sensor. The output changes by 1.6 V±10% if the sensing object moves by 1 mm. The standard upper and lower limits of the output are 6.5 and 0 V respectively. If there is no sensing object or the reflectivity of the sensing object is low and no light is reflected to the Sensor, the analog output will output the standard upper limit. Analog output (V) Analog Output Diagram Light source surface Sensing object surface Note: As the optical axis will be adjusted later, temporarily fix the Sensor. Z4D-F04D ON/OFF Output Diagram Wiring Connect the Sensor to the controlling device using an attached sensor cable. Do not switch the power ON during wiring. Refer to the instructions on the Sensor and the connection diagram (page page 8) before connecting the Sensor to the controlling device. Axis Adjustment When the Sensor power is switched ON, the red transmitter indicator is lit. Move the Sensor so that the red beam (see the figure below) focuses on the object. The entire light beam should be focused on the object or an error will result. The ON/OFF position can be set with the distance adjustor if a sensing object is at the sensing range (i.e., 4±1.25 mm). The ON/ OFF position will shift farther from the Sensor if the distance adjustor is turned clockwise and the ON/OFF position will shift closer to the Sensor if the distance adjustor is turned counterclockwise. If there no sensing object is present or if the reflectivity from a sensing object is too small to reach the Sensor, the output will turn OFF. After the optical axis has been adjusted, tighten the mounting screws firmly. Surface of object Correct Incorrect Spot 10 Distance adjustor position Z4D-F Z4D-F Precautions Install the Sensor in a clean environment keep the filter (on the front of the Sensor) free from oil and dust. If affected by oil or dust, clean the Sensor as follows: 1. Use a blower brush (used to clean camera lenses) to blow large dust particles from the surface. Do not blow the dust away with your mouth. 2. Use a soft cloth (for lenses) with a little alcohol to remove the remaining dust. Do not use a scrubbing action when cleaning as a scratch on the filter could result in the Sensor malfunctioning. Connector Environment Refrain from using the Micro Displacement Sensor in a strong electromagnetic field or in an environment where the operation of the Sensor is subject to the reflection of intensive light (such as a laser beam or an electric arc welding machine). The Displacement Microsensor cannot accurately sense a mirrorlike object, a transparent object, one with an extremely small reflection ratio, an object smaller than the diameter of the Sensor’s sensing spot, or an inclined object. Wiring When removing the connector from the Sensor, be sure to hold the connector and pull it together with the attached cable. The power supply cable for the Z4D-F04A/D should not be wired with high-voltage lines or power lines in order to avoid interference, damage, or malfunction. If pulled by the cable alone, it will damage the lock mechanism inside the connector. Do not solder wires to the Sensor connector, otherwise the Sensor may malfunction. Interference Others Z4D-F04A/D Micro Displacement Sensors can be installed within close proximity to each other and operate independently without interference (refer to the figures below). However, if they are installed at an oblique angle to each other, interference may result. Do not use switching power supplies that generate excessive noise, which may cause sensing errors. The following LC filter effectively reduces noise. Sensor Power source The Sensor cannot sense an object accurately if the surface of the object consists of different materials placed next to each other (refer to the figures below). In such a case install the Sensor so that the boundaries of the materials and the Sensor are parallel. When using the Micro Displacement Sensor in combination with another type of Sensor (such as a Photoelectric Sensor), the sensor beams should be as close to perpendicular as possible. 11 Z4D-F Z4D-F ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
