About Gira Eco 2. About Gira Eco 2.1. Proper use Via the Gira Eco, up to five compatible charging points can be integrated into the KNX system. The Gira Eco is a KNX system device and complies with the KNX guidelines. Note Gira Giersiepen GmbH &...
The Gira Eco is connected to the KNX installation via KNX/TP. Depending on the model used, charging points are connected to the gateway either via IP or RS485 (Modbus). The Gira Eco unites the required connections in one gateway. Thanks to the integrated RS485 connection, no additional USB adapter is required.

About Gira Eco Grid-supporting control The Gira Eco enables the grid operator to control the power consumption if necessary by reducing the charging current or interrupting the charging process. Control or interruption of vehicle charging may occur during high load periods in order to prevent a critical grid situation.

► See “Group objects” on page 48. Electricity meter at the charging point The Gira Eco supports the retrofitting of electricity meters at the charging point if the charging point does not offer the integrated measurement of consumption values (current, power and energy). Elec- tricity meters with IP connection (Modbus TCP) and RS485 connection (Modbus) can be connected.

Press the [F1] button. Work steps 1. Create Gira Eco as device in the ETS ► See “Creating the device in the ETS” on page 30. 2. In the ETS, assign the device and its individual address corresponding to the KNX topology.
Commissioning and configuration 8.3.1. Creating the device in the ETS Depending on whether the product database entry already exists in the ETS catalogue or whether the device is already being used in your existing project, different work steps are required in order to use the current version.
Page 31
Commissioning and configuration Updating a product in the existing project Requirement: New product database entry exists in the catalogue. 1. In the ETS, open the project for which the device is to be updated. 2. Search for the new product database entry in the catalogue and add the new version of the device to the devices in your project.
Besides the individual address in the KNX network, an IP address, the subnet mask and the address of the standard gateway in the IP data network must be assigned to the Gira Eco. You can enter the settings manually in the ETS or receive them automatically (obtain the data from a DHCP server, e.g.
Commissioning and configuration Serious misconfiguration Default values are set if you want to use the setting “Use permanent IP address” but then forget to fill in the appropriate fields. Devices with the default value 127.0.0.1 as fixed IP address will therefore not start up properly.
Commissioning and configuration How to recognise successful assignment of the individual address: • Device: The programming LED on the device is off. • ETS: The completed transfer is indicated on the “History” tab by a green marking. Programming flag “Adr” is set and “Cfg” is not set. More information about this and other flags is available from the ETS documentation.

Commissioning and configuration Establishing compatibility In case of incompatibility, you will need to uninstall the application program. • The device remains in the existing projects. • The device keeps the version of the application program in the ETS. • The entire parametrisation is rejected. •...
If several charging points are configured, connect and configure charging points individually. 2. Configure the Gira Eco. 3. Connect the Gira Eco with the charging point(s) using the RS485. Calling up the context help in the ETS 1. Enable the “Context help” button in the “Parameter” tab in the toolbar.
ETS, the DLM determines how much current is avai- lable for charging. Figure 24: System Gira Eco Note The smart meter must measure that current of the line that is protected by the overcurrent protection device.
Page 41
Parametrisation The DLM thus responds dynamically to the current consumption in the building and flexibly distribu- tes the ever-changing current to the charging points in order to remain within the consumption limit. The DLM takes into account the defined minimum and maximum charging current of each charging point.
Page 42
Parametrisation Activation 1. Activate load management in the like-named tab and select “dynamic”. 2. Set the overcurrent protection device and the load reserve. 3. If required, prioritise a charging point to which the DLM should provide the highest possible char- ging current as a preference.
Page 43
Parametrisation Example: Current distribution with prioritised charging point Three charging points need to be charged simultaneously. Consumer V1 consumes 8 A at the same time. The charging points (CP) are configured as follows: • CP1: min. charging current 6 A / max. charging current 12 A (prioritised) •...
Parametrisation 9.2. Activating static load management Use case • Use a sub-distribution available specifically for charging electric vehicles with its own fuse, without taking other dynamic consumers into account. • Charge several vehicles at the same time. Maximum charging current overall The maximum charging current overall is the relevant parameter for calculating the maximum permis- sible current value shared by the charging points.
Page 45
Parametrisation Example: Current distribution with prioritised charging point Three charging points need to be charged simultaneously. The charging points (CP) are configured as follows: • CP1: min. charging current 6 A / max. charging current 12 A (prioritised) • CP2: min. charging current 6 A / max. charging current 8 A •...
Parametrisation 9.3. No use of load management Use case • The existing mains connection is sufficiently dimensioned to specify a target charging current that the electric vehicle can use as a maximum. • External load management is used. Defined current value per charging point If load management is deactivated, a maximum current value is set for each charging point via a group object.
Page 47
Parametrisation Connection The “Electricity meter” parameter is optional and is only available for charging points without an integrated electricity meter. Note If you are using a charging point without consumption value measurement with DLM, the provided setpoint current is automatically used as the actual current. Figure 26: Electricity meter at the charging point 1.
Group objects 10. Group objects The Gira Eco makes the corresponding group objects available according to its range of functions. In addition to generally valid and DLM functions, there are model-dependent functions. The correspon- ding group objects appear as soon as you have assigned a manufacturer and model to the charging point.

Troubleshooting 11.2. Generating log files Support uses log files to obtain information to help analyse your problem. You generate these log files via the device website and download them as a ZIP file. You configure the scope of the information contained in the log files using the logging mode. Our Sup- port may ask you to configure the logging mode.
• You might be using an older ETS version. The application accesses ETS functions that are not sup- ported by older ETS versions. Make sure that your ETS version is up to date. The Gira Eco is config- ured via the ETS from v5.7.5. Older versions of the ETS cannot be used for configuration.
