Series Function Details Integrated Display (Series 7)/Remote Monitor Unit (Series 3) Output operation The output operation can be selected from the following: Output (hysteresis mode and window comparator mode) corresponding to instantaneous flow rate, Output corresponding to accumulated flow, ccumulated pulse output Note) t the time of shipment from the factory, it is set to hysteresis mode and normal output. When a temperature sensor is attached, the output to the temperature sensor is selectable only for OUT. (Refer to How to Order for details.) Indication color The indication color can be selected for each output condition. The selection of the indication color provides visual identification of abnormal values. (The indication color depends on OUT setting.) ON: Green, OFF: Red ON: Red, OFF: Green lways: Red lways: Green Response time The response time can be selected depending on the application. ( second for default setting) bnormalities can be detected more quickly by setting the response time to.5 seconds. The effect of the pump fluctuation and flickering of the display can be reduced by setting the response time to seconds. Note) The temperature sensor output is fixed to 7 seconds. Response time.5 seconds second seconds pplicable model Integrated display Remote monitor unit Series 7 Series 3 Selection of display on sub screen The display on the sub screen in measuring mode can be set. External input function This function can be used when external input is available. The accumulated value, peak value, and bottom value can be reset by remote control. ccumulated flow external reset: This function resets the accumulated value to when an input signal is applied. In accumulated increment mode, the value will be zero when reset, and the accumulated value will increase from zero. In accumulated decrement mode, the value will be the set value when reset, and the accumulated value will decrease from the set value. When the accumulated value is memorized, every time the accumulated value external reset is activated, the memory element (EEPROM) will be accessed. Take into consideration the maximum number of times the memory element can be accessed, million times. The total of external input times and accumulated value memorizing time interval should not exceed million times. Peak and bottom reset: Peak and bottom values are reset. Forced output function Output is turned ON/OFF compulsorily when starting the system or during maintenance. This enables confirmation of the wiring and prevents system errors due to unexpected output. For the analog output type, the output will be 5 V or m for ON and V or 4 m for OFF. lso, the increase or decrease of the flow and temperature will not change the on/off status of the output while the forced output function is activated. ccumulated value hold function ccumulated value can be saved on the unit even when the power supply is turned off. The accumulated value is memorized every or 5 minutes during measurement, and continues from the last memorized value when the power supply is turned on again. The lifetime of the memory element is million access cycles. Take this into consideration before using this function. Sub screen Displays the set value. (The set value of OUT cannot be displayed.) Integrated display Displays the accumulated value. (The accumulated value of OUT cannot be displayed.) Remote monitor unit Set value display ccumulated value display Peak value display ottom value display Displays the peak value. Displays the bottom value. Line name display Displays the line name. (Up to 6 alphanumeric characters can be input.) Fluid temperature display Displays the fluid temperature. (When the temperature sensor type is selected.) OFF Displays nothing. The above are examples of integrated displays. (Same as remote monitor unit) Power saving mode The display can be turned off to reduce the power consumption. In power saving mode, decimal points blink on the main screen. If any button is pressed during power saving mode, the display is recovered for 3 seconds to check the flow, etc. Setting of secret code Users can select whether a secret code must be entered to release key lock. t the time of shipment from the factory, it is set such that the secret code is not required. Peak/ottom value indication The maximum (minimum) flow is detected and updated from when the power supply is turned on. In peak (bottom) value indication mode, this maximum (minimum) flow is displayed. Keylock function Prevents operation errors such as accidentally changing setting values.
