HINTS ON CORRECT USE Mounting amplifier · If the amplifier cable is placed together with power lines or high voltage lines in the same conduit, detection errors may occur due to noise interference. Isolate the amplifier cable from these lines. · If there are several colors in a single beam spot, the CZ-V1 determines the color by averaging those colors. Therefore, it may produce an output even though the color is different from the registered color. · To extend the cable length, use a cable with at least a 0.3 mm2 nominal cross-section area. Limit the length of cable extension to 100 m or less. (To connect several units, contact Keyence for further information.) · When using a commercially available switching regulator, ground the frame ground terminal and ground terminal. · Do not use the CZ-V1 outdoors. · Even when the same color is detected, the displayed value may vary depending on the characteristics of each amplifier, the length of the fiber cable and the location. · When any of the external inputs (calibration, synchronization or bank selection) are not used, cut the appropriate input cables (pink, purple, orange/purple, yellow/purple or green/purple) at the root or connect them to the "+" terminal of the power supply. · Target movement and fiber unit orientation To stabilize the sensor output at a border, mount the fiber unit parallel to the border line as much as possible. Incorrect Correct Target movement direction Target movement direction
