	~~[[File:Advanced_Primary.png\|alt=~~Advanced ~~Primary\|frameless\|450x450px]]~~		Advanced settings are the settings that most of the time are left default. Only on special occasions, those settings must be changed.
	~~To access~~ the ~~DLM functionality~~, ~~the user~~ must ~~first enable the DLB functionality~~.

	# '''~~Measuring device~~'''~~: The meter should be selected. For UK~~ chargers~~, it is possible to choose CT clamps.~~		* '''Phase connected''' – detected automatically
	# '''~~Energy meter address~~'''~~: This information can~~ be ~~found in the meter settings accessed through the meter display~~. ~~If the address cannot~~ be ~~located, it is recommended~~ to ~~consult the smart meter manual~~.		* '''Phase sharing mode''' – type of chargers in group
	# '''~~Current update interval~~'''~~: By default, it is set to 3 seconds. However, there may~~ be ~~cases where~~ the ~~user needs to increase this value. For instance, if there are significant distances between~~ the ~~chargers and~~ the ~~smart meter or if there are numerous interconnected chargers.~~		* '''Current sharing mode''' – Current is distribution mode
			** Equal - Energy will be distributed equally among all active chargers
			** By Priority - Energy will be distributed based on priority. Chargers will be prioritized according to their '''charging state'''.
			* '''Communication timeout''' – delay before warning

			=== Secondary device configuration ===
			[[File:Secondary config.png\|frameless\|650x650px]]
			After Primary device configuration, it’s mandatory to enable Dynamic load management mode and correctly set-up '''each secondary device'''. (This action must be repeated for each new secondary device)

	~~=== Dynamic Load Management ===~~		For each secondary device few settings must be adjusted:
	~~[[File:2023-07-03 08 27 42-Window.png\|right\|frameless\|397x397px]]~~
	~~When setting up all the previous configurations, it is time to proceed with the main DLM~~ settings~~. To enable these settings, the user~~ must ~~first activate DLM.~~

	# '''~~Master mode~~'''~~: This setting designates the charger as the master charger.~~ It ~~should only be enabled for one charger, which will handle all the calculations and establish communication with the smart meter.~~		* '''Max power from grid''' - It is advisable to set it to a maximum of 16 A (for 11 kW chargers) or 32 A (for 7.4/22 kW chargers)
	~~# '''Measure grid load''': This setting should be enabled if DLM functionality with a meter~~ is ~~desired. If there are no plans~~ to ~~use a smart meter,~~ it ~~is important to disable this setting to prevent meter errors due to lack of connection. Please note that this setting is exclusively available for the master charger.~~
	~~# '''Phase sharing mode''' - This configuration determines the type of chargers being used in the circuit. If all chargers are connected~~ to a ~~single phase, select "1 Phase." If all chargers are connected to three phases, select "3 Phase." If there is a mix~~ of ~~one-phase and three-phase chargers, select "Mixed."~~
	~~#* ''In unbalanced grid cases~~ (~~severe differences of load on phases), "mixed" mode can be used to optimise the number of charging vehicles. In this case the current is firstly distributed~~ for ~~3 phase capable EVSEs, and when there is a significant surplus of power on any phase, the other EVSEs will use 1 phase charging mode.''~~
	~~# '''Current sharing mode''' - There are two distinct current sharing modes available:~~
	~~#* Equal distribution: Energy will be distributed equally among all active~~ chargers.
	#* Distribution by priority: Energy will be distributed based on priority. Chargers will be prioritized according to their charging state, and those with higher priority will receive maximum charging power.
	~~#** ''For example, if we have a 100~~ A grid and five connected chargers, each capable of accepting 30 A, the first three chargers will receive 30 A each. The fourth charger will receive only 10 A, and the fifth charger will not initiate the charging process at all. This setting is exclusive to the master charger.''
	# '''Phase connection''' - The user needs to select this option for each charger in the circuit. This setting configures the charger type, whether it is a single-phase, two-phase, or three-phase charger. Configuring this accurately is crucial for more efficient load balancing. It is important to ensure that the phase numbering aligns with the meter's phase numbering; otherwise, DLM functionality may be affected.
	# '''Slave Modbus address start''' - This setting is exclusive to the master charger. The user needs to specify the starting address for the slave chargers. For instance, if the start address is set to 1, the first slave charger should have address 1, the second should have address 2, the third should have address 3, and so on.
	~~# Each slave charger has its own specific setting called "'''Slave Modbus address'''". This setting must be configured individually~~ for ~~each charger~~.
	~~# '''Number of devices''' - This setting is available only for the master charger. The administrator must specify the total number of slave~~ chargers ~~that will be connected in the circuit.~~

			* '''Secondary device''' – enabled
			* '''Secondary device ID''' – for the first device it must be as set in the master, for each new secondary device this must be increased by 1
			* '''Advanced settings''' – must match with the primary device settings
