  3. Connect an antenna to the module MCX antenna connector and route the cable along the guiding pins in the meter housing.

  4. Close the meter housing. The module is powered once the lid is closed.

  5. Activate the module using either the Elvaco OTC App, or by using the meter front buttons (see activation section for details).

Activating the module

Upon delivery, CMi6140 is by default configured to be inactive, which means that no messages will be transmitted until it has been activated. Before activating the module, make sure the mounting procedure has been followed. There are two ways to activate the module:

Activation using the meter front buttons
  • MULTICAL® 403: Press and hold both buttons on the front of the meter until “CALL” is shown on the meter display.

  • MULTICAL® 603 and MULTICAL® 803: Press down the two arrow buttons on the front of the meter until “CALL” is shown on the meter display.

Activation using the Elvaco OTC App

NFC scanning position

MULTICAL® 403: Place the phone in the center of the raised section on the back of the meter.

MULTICAL® 603: The meter has two slots:

  • Left slot: Middle of the raised back section

  • Right slot: Right side of the raised back section

MULTICAL® 803: Open the meter and place the phone close to the device.

Read the module status via the meter display

In addition to the Elvaco OTC App, the status of the module can be read via the meter display.

To retrieve the status of the module via the meter display, enter the tech loop of the meter display and request the status information of the module. For detailed information, please refer to the Kamstrup MULTICAL Technical description.

See the following tables for information accessible in tech menu of the meter and how to interpret the status:

Connecting to the network

When activated, the module will attempt to connect to the NB-IoT network. When the module successfully connects to the network, a meter readout will be triggered and automatically sent to the receiving system. The network status can be read through the Elvaco OTC app or the meter display (see section Read the module status via the meter display for details).

If the module fails to join the mobile network, it will perform retries until it succeeds. The time between each attempt will increase for every attempt until it is performed once every day. A new join attempt cycle can be manually forced by deactivating and activating the module using the Elvaco OTC App.
