In this tutorial we will learn how to connect the Load guard to the INCH Charging Station.
Load Guard Configurator
First we need to connect to the Load Guard and set up the device itself. For configuring the device we use a program called Load Guard Configurator. You can download it from our Knowledge Centre under section Load Guard.
After downloading the Load Guard Configurator, we need to connect the Load Guard to the same network as the INCH charging station and computer where we will configure the device.
Upon opening the configuration software you will be presented with the list of Load Guard devices found on the network. If there are no devices found, disable the firewall on your PC and try to rerun program again. After selecting connect Load Guard, the configuration window will open. This window in splited in two main parts. On the left you can see live data and measurements of the Load Guard. On the right side you will find the Load Guard Communication Settings.
Configuration of the network
First thing to do is to configure the network on the Load Guard device. You need to choose between setting up dynamic or static IP address. We always recommend using static IP addresses whenever possible.
In order to setup static IP address we select it first and then enter appropriate IP addresses, network masks and gateways. To apply the settings, select Save changes and wait for the Load Guard to restart.
Synchronizing the time
In order to connect the Load Guard to the charger we need to change a few settings in the Load Guard Configurator. The first thing to do is to synchronize the time by selecting the Sync device time icon.
Entering the IP address and Serial number
On the bottom left side of the Load Guard Configurator, we need to enter the IP address and Serial number of the Master charger.
After entering the correct data, we select Save changes and move on to configuring the charger.
MyINCH Configuration
First we need to open MyINCH web interface. We navigate through the menu to Power managment and click on General configuration. We need to enable Power managment, and set master charger as localhost by clicking on Running on this charger. So the Power managment Master charger is the current one. We click Save and go to Building power limits menu. We need to enable the option - Load Guard installed, by ticking the checkbox. The window will change and we need to enter the Maximum building currents for each phase separately. Then we need to select Load Guard type. Select the Etrel Load Guard, if you are using anything else, select the appropriate option.
Then enter the Load Guard serial number and the current charger serial number.
On the bottom of the window we need to enter the Maximum charging currents if the connection between the charger and the Load Guard is disconnected. This is a failback setting and needs to be entered with some consideration in mind.
Saving and Restarting
After all that we Save and Restart the charger from the Diagnostics menu.
Final check
After restarting the charger we should have the Load Guard icon on the top right corner. By selecting it we can confirm that the Load guard is connected. To further confirm everything is in order we can also check in the settings, navigate to the Building power limits menu and check the Communication status. If it is red, it means the Load Guard and INCH are not communicating.
We can also check if the status icon is green in the Load Guard Configurator. If it is red then it means, the Load Guard and charger are not communicating with each other.
You can select different interval of how often the Load Guard sends data to the INCH charger, but never go bellow 200 milliseconds.
Enabling a Secondary Master
You can also enable a Secondary Master charger if needed in larger Clusters. Process of establishing connection with the Secondary charger is same as for the Primary one.
