IMPORTANT
• Prepare the HDR40 and CNT separately for the BCD output.
• Refer to CONNECTOR PIN ASSIGNMENT to prepare a cable by yourselves.
• The connector model No. is HDR-EC50LFDT1-SLE+ (Honda Tsushin Kogyo Co., Ltd.).
• Be sure to confirm the polarity in wiring.
• Make sure that the saturation voltage (residual voltage) of an input device meets the detecting levels of the unit. Other-
wise the unit may not operate correctly.
• Connect load within the specifications.
