4.7 Locking the Infrastructure Socket Outlet
(EV-CC-...-CBC-... only)
The locking function of the Infrastructure Socket Outlet is controlled using connections
LO+/LO- and LD1/LD2.
Via terminal blocks LO+ and LO-, a voltage of ±12 V and a corresponding polarity are ap-
plied to the locking actuator for a specific period. When reaching a defined state, the output
becomes disconnected from the power.
In order to detect the locking state, the resistance between LD1 and LD2 is evaluated.
By default upon delivery, the device has the following configuration: A resistance of 0 ohms
defines the locked state and an open connection (infinite resistance) between LD1 and LD2
defines the unlocked state.
If, after a locking or unlocking pulse, no corresponding feedback can be measured at LD,
this process will be repeated automatically. The number of maximum permissible repeti-
tions and maximum duty cycles to be observed is taken into account.
The default settings are adapted to the Infrastructure Socket Outlet from
Phoenix Contact. For controlling other locking actuators, the parameters for con-
trolling the socket and evaluating the locking feedback can be configured via Modbus.
For the relevant parameters, please refer to Section 9, “Modbus description”.
For connection examples of an Infrastructure Socket Outlets from Phoenix Contact, please
refer toFigure 7-1 on page 35.
4.8 Configuration
The charging controller is basically configured using configuration switches S1 and S2.
For additional information on configuration, please refer to:
– Table “Configuration switches S1 + S2” on page 13
– “Connection examples” on page 35
– “Flow charts for the charging process” on page 47
– “Modbus description” on page 53
