    Flow Rate Indication The Florex accepts DC Linear Current / Voltage Input from the Flowmeters to measure the Flow Rate. The value of the Flow Rate is displayed in accordance with the value for Range Low / High and the Resolution selected on Input Configuration Page.
  • Page 6 3. Press ENTER key to Reset the Total value to 0. Notice that upon resetting the Flow Total to 0, the FLOREX immediately starts accumulating the Flow Total if the Flow Rate is other than 0. If the set Passcode value does not match with the value set for the Supervisory Passcode set on Utility Page, the FLOREX reverts to MAIN Display Mode without resetting the accumulated Total.
  • Page 7 Alarm Acknowledgment The FLOREX is provided with the output (Relay/SSR) facilitating “hard” alarm for Flow Rate as well as Flow Total. That is, if any or both the alarms are activated (alarm condition is occurred), the output (Relay/SSR) associated with their respective alarms gets energized and sounds the buzzer/hooter.

  • Page 11 FLOREX User Manual Settings Parameter Description (Default Value) TOTAL ALARM-1 SETPOINT This parameter is available only if ‘Total Alarm-1’ is selected to 0 to 99999999 ‘Enable’. If enabled, the alarm is activated whenever the (Default : 5000000) accumulated Flow Total is at or above the Total Alarm-1 Setpoint.

  • Page 12: Pages And Parameters

    PAGES AND PARAMETERS ORGANIZATION The FLOREX requires various user settings that determine how the FLOREX will function or operate. These settings are called Parameters. The parameters are always presented in a fixed format: The Upper Row of Lower Readout displays the parameter name (Identification Tag) and the Lower Row displays the options / set value.
  • Page 13 MAIN Display Mode (by depressing PAGE key) without pressing the ENTER key will not store the altered value in the FLOREX memory and the previous set value will be retained. Also, if the power failure occurs prior to pressing ENTER key, upon resumption of power, the FLOREX reverts to MAIN Display Mode without storing the altered value and retaining the previous set value.
  • Page 14 9. Notice that it requires setting Lock to ‘Yes’ once for Locking but twice for Unlock. Also, for Unlock, the setting to ‘Yes’ must be entered twice during the same duration for which the FLOREX is powered. That is, setting ‘Yes’ once prior to power loss and once after resumption of power shall not Unlock.
