[. . . ] 142-001 SAFETY PRECAUTIONS This manual describes the instructions, operating procedures and precautions for using the CZ Series. Before beginning operation, please read this manual carefully to get the most from your CZ Series. Keep this manual handy for future reference. WARNING RGB Digital Fiberoptic Sensors CZ Series Instruction Manual · The CZ Series is intended for the detection of target objects. Do not use the CZ Series in a safety circuit to protect the human body. [. . . ] Press the SET button and then release it. The calibration indicator illuminates momentarily and the reference color is saved. MODE q When calibration/differentiation fails Check the following points. · Check whether the fiber unit is mounted properly (detection distance and detection angle). (See page 7. ) · Perform the sensitivity adjustment. (See below. ) · Select the other differentiation mode and then perform calibration again. (See page 3. ) LCD display indication Current value q Matching rate display (Matching rate display) Displays the matching degree (matching rate) of CH Channel the color of the currently Indicates the channel of detected target to the the amplifier currently v reference color registered being monitored. Mode "C" indicates that the current mode is C or C + I. Nothing appears while in I mode. * Displays a value between 0 and 999. (Higher value indicates a better match. ) MODE CH OUT TIM SET SET DLY. OFF N. C N. O Calibration indicator Press this button once. q To ignore certain color differences There are two methods for ignoring color differences. · Perform the sensitivity adjustment after calibration. (© See the lower right part of page 4. ) · Use the quick color difference cancellation function. In 1-point calibration, hold down the SET button and continue the calibration with targets of different colors. The CZ Series ignores the color variation and saves them as the reference color.

With the target removed, press the SET button and release it. The calibration indicator (orange LED) goes off. 3 4 MODE · Stable LIGHT status is obtained with 110P (%) or more. · Stable DARK status is obtained with 90P (%) or less. [. . . ] To finish the selection, hold down the MODE button and press the DOWN button for 3 seconds. "CH" stops flashing and remains illuminated. 3 4 When the external synchronization input cable (purple) receives a signal (connected to 0 V), the control output retains the condition at that exact moment.

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. [. . . ]
