Replacement Meter

Replacing the meter requires sequential execution of operations:

  • Dismantling the meter
  • Installation of the meter

Dismantling the meter

  1. Go to the SLCC page.

  2. Select the tab Settings -> Main.

  3. Press the Uninstall button in the Meter section. A modal window for entering dismantling parameters will appear.

    3.1. Set the date and time for removing the meter. 3.2. If necessary, check the box “Change Registers” and enter the value of the active energy read from the meter dial. 3.3. Press the OK button.

  4. The meter is dismantled (disconnected from SLCC). The meter section is empty. The “Bind” button has appeared

Installing the meter

  1. Click the Bind button in the Meter section. A modal window will appear for entering the parameters of the installed meter.

    1.1. In the input field “Serial number” start entering the serial number of the meter. The system will prompt the serial numbers of free meters that start with the entered characters.

    1.2. Select the required number from the proposed numbers. After selection, a green check mark will appear on the right side of the input field, signaling that the meter is selected.

    1.3. Set the time and date of installation of the meter.

    1.4. Enter the value of the initial meter reading (required).

    1.5. Click the Save button.

  2. New meter installed (tied to SLCC)

Free meter is a meter not tied to SLCC at the moment.

What’s going on in the database?

When dismantling the meter, in the records of the meters table, in one transaction the value is_archive = true is set and a complete duplicate of the record is created with a different id and empty values in the following fields: cabinet_id, from_dt, to_dt.

When selecting a meter for installation to SLCC, only meters for which is_archive = false and an empty cabinet_id are included in the selection.

When mounting the meter, the cabinet_id, from_dt values are filled in the meters table entry. Now, the metrics coming from this meter will be associated with the specified SLCC.

Solution of problems

The system does not prompt the required meter number

The reasons:

  • The meter with the given serial number has not yet been registered in the system.
  • The meter with the given serial number is tied to another SLCC at the moment.

Decision:

  • Make sure that there is a meter with the given serial number.
    • If absent, register the meter with the given serial number.
    • If available, dismantle the meter from the SLCC to which it is currently attached by completing points 1-4.
