Installation

Mounting the meter connectivity module

Before being mounted into a Diehl SHARKY 775 or a Diehl SCYLAR 548 meter, it is easiest to start off by mounting the SIM card.

  1. Slide a SIM card (size: Nano) in the SIM card holder.

  2. When the SIM card has been mounted, open the meter by folding down the side latches.

Having the SIM card inserted in the device, mount the module in either a Diehl SHARKY 775 or a Diehl SCYLAR 548 by following the procedure below.

  1. Connect the meter interface cable (white) by attaching it to the meter

  2. Push the module (green) into meter slot 1 according to the following image. The guiding pins will help to get it into the right position.

    Note

    To be able to align the NFC antenna correctly, it is only possible to utilize meter slot 1.

  3. Connect the NFC antenna (orange) to the module according to the following image. Remove the protective film covering the adhesive on the backside of the NFC antenna. After connecting the antenna and removing the film, best practice is to firstly put the larger part in place, followed by pressing the thin part of the antenna into its position.

  4. Connect the meter interface cable (white) to the module (green).

  5. Attach the antenna of choice to the MCX connector, and connect the power connector before closing the lid.

Caution

This is an electrostatic-sensitive product. Observe the necessary ESD protective measures when installing the product.

Connecting the battery

If not already assembled to the meter, see Diehl Metering's mounting instruction for external battery packs. When the battery pack has been mounted properly alongside the meter, connect the power cable from the battery to the power connector on the CMi6160.

Connection of the antenna

Using internal antenna

  1. Place the antenna in the meter housing according to the following image.

  2. Connect the antenna cable to the MCX antenna connector on the module.

    Note

    Make sure to not clamp the antenna cable when closing the lid.

Using external antenna

  1. Make a hole in the rubber grommets/sealing and push the MCX connector through the grommets/sealing. Make sure that the thicker part of the antenna cable is in the grommet/sealing.

  2. Connect the antenna cable to the MCX antenna connector on the module.

Activating the module

Upon delivery, the module is set to inactive mode, which means no messages will be transmitted from the module. The module can be activated in one of the following ways:

Via the Activation at flow feature

  1. Make sure the module is configured with the Automatic activation at flow enabled. Utilize the Elvaco OTC App to check that the correct configuration is applied. To have the function enabled, Power mode should be set to Standby.

  2. Once the meter detects flow of water and has registered sufficient water flow, the module will be activated and start to deliver meter data. The module checks once every hour if the meter has registered sufficient water flow.

Note

Sufficient water flow is when the meter has registered permanent water flow for 3 hours.

Via the module push button

  1. Carefully press the push button of the module for at least five seconds.

  2. Release the button when the green LED lights up.

  3. Wait for up to 10 seconds.

The module indicates start-up by flashing red and green LEDs for one second.

Via Elvaco OTC app

  1. Open Elvaco OTC app (available for Android and iOS).

  2. Scan the module (make sure NFC is activated on the phone).

  3. Go to Apply mode.

  4. Set the power mode to Active.

  5. Select Apply settings.

  6. Scan the module to apply new settings.

    To verify that the module has been activated, go to Inspect, scan the module, and make sure that power mode is set to Active.

Tip

Having the meter closed and the meter display facing you, the NFC antenna is located in the upper left corner of the meter.

Connecting to the network

When activated, the module will attempt to connect to the NB-IoT network. This phase is indicated by the green and red LED light up for 1 second, followed by short flashes on the green LED until the module has joined the network. When the module succeeds in connecting to the network, the green LED will be lit for 8 seconds, as illustrated in the image below. Upon successful connection, a meter readout will automatically be sent to the receiving system.

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 started anytime by using the push button to reboot the module or by deactivating and activating the module using the Elvaco OTC App.
