UDP command: failsafe
The
failsafe
function is a way to detect a failure of the network
communication between the UDP application and the charging station. In
this case, the charging station will fall into a state with a definable current
limitation. By default, the
failsafe
function is disabled and must be
enabled by the application.
This function must be used with caution. It should be noted that all xChargeIn
charging stations offer multiple ways to set up the device in such a way that
electrical overload can be avoided. The hardware switches (DIP switches)
allow to configure a limit for the maximum charging current that cannot be
increased by UDP commands. The charging station also offers a monitoring
function of the electrical connection of the household (in conjunction with an
appropriate meter) preventing overload situations.
A triggered
failsafe
function can be recognized via the data offered by
re-
port 2
: the "Enable sys" value is set to 0 and "Max curr" is equal to "Curr
FS". After the
failsafe
function has been activated due to a timeout, you
must set the values of current and the load enable again using the
associated commands
currtime
/
curr
and
ena
.
