Page 13: Summary Of Product Parts
Summary of Product parts Front Element Description Main screen (2-colour display) Displays the flow, the status of setting mode and error code. Displays the accumulated flow, set value, peak/bottom value, fluid temperature and Sub screen line names. Output display (Indicator LED) Displays the output status of OUT1 and OUT2.
Page 14: Definition And Terminology
■Definition and terminology Terms Meaning The total amount of fluid that has passed through the device. If an instantaneous flow Accumulated flow of 10 L/min continues for 5 minutes, the accumulated flow will be 10 × 5=50 L. Accumulated flow A function to reset the accumulated flow to zero by using an external signal.
Page 15 Terms Meaning The range of ON/OFF threshold values that can be set for those products with a switch Set flow range output. Output type that has only 2 conditions, ON or OFF. When in the ON condition an Switch output indicator light will show, and any connected load will be powered.

Page 22: Flow Setting
Flow Setting Measurement mode The mode in which the flow is detected and displayed, and the switch function is operating. This is the basic operating mode; other modes should be selected for set-point and other function setting changes. ∗: The outputs will continue to operate during setting. ∗: If a button operation is not performed for 30 seconds during the setting, the display will flash (This is to prevent the setting from remaining incomplete if, for instance, an operator were to leave during setting).
Page 23: Default Settings
Default settings When the flow exceeds the set value, the switch will be turned ON. When the flow falls below the set value by the amount of hysteresis or more, the switch will be turned OFF. If the operation shown the below is acceptable, please keep this setting. Refer to the following pages for how to change the settings.
