Cable wiring

Please see the page of mechanical and electrical installation.

Parameter setup

Please refer to the parameter set-up page.

Set-up steps as below:

1. Connect cable first according to the cable wiring section on this page.

2. Set up parameter E01 for selecting NC(Normal Close) or NO(Normal Open) when there is no signal.

3. Set up parameter E02 for specifying output signal content.

   1. For selecting “pulse output”

      1. Use E03 to confirm each pulse width.

      2. Use F03 to simulate specific pulse output frequency at OCT for testing with external devices.

   2. For selecting “out of range flow volume notice”.

      1. Use D04 to turn on the alarm.

      2. Use D05 D06 for specifying normal flow range.

      3. Use D07 for specifying hysteresis range percentage. D07 is a positive value, it means the ranges single must exceed in order to disable the alarm.

      4. Set up F01 and F02 for simulate flow volume and go back to the monitoring screen to confirm the alarm works

      5. Turn off the simulation mode.

   3. For selecting “Total Ala.” (“Inform of over total target”)

      1. Use D08 to turn off alarm

      2. Use D09 for specifying notification conditions. "Larger Than" is for positive flow direction, "Less Than" is for negative flow direction.

      3. Use D10 for specifying total target, positive number is for positive flow, negative number is for negative flow.

      4. Set up F01 and F02 to simulate flow volume and go back to the monitoring screen to confirm the alarm works.

      5. Turn off the simulation mode.

4. Go back to the monitoring screen, finish.

Pulse output

Pulse output is based on the frequency of the paddle wheel’s revolutions. Due to not adapting LORRIC’s data processing technology, it is only applicable to the environment without high precision request. A pulse will be sent by every 180° revolution. To calculate the total flow volume for a certain period of time, count the number of pulse signals received then divided by the corresponding K-value this manual provides. K value is defined by pipe size and material. Please refer to T-connector page.
