Mennekes AMTRON Xtra User's Operation Manual page 43

The HC controller provides five operating modes that can be
changed even during operation depending on the
configuration. The operating mode is selected over the
service interface or the MENNEKES Charge APP.
The availability of the operating modes and functions
depends on the version of the charging station and the
configuration of the charging station during the setting-
up process. When switching to operating mode "SCU",
the HC controller must be restarted.
Operating mode "Manual (Remote)"
In this operating mode, the charging process is controlled by
the Charge APP.
 See table "Functional description of manual operating
mode (remote)" on page 12.
Operating mode "Time-Controlled (internal)"
In this operating mode, the charging process is controlled by
the integrated tariff-switching timer. This allows adapting the
available charging current to various main / off-peak tariffs.
For example, during an off-peak period the charging station
can charge with higher charging power than during more
expensive main tariff periods.
The valid tariff periods supplied by the electricity provider are
entered in the Charge APP and the charging station adapts
the charging current according to the periods entered.
Updating the tariff-switching timer and changing of
daylight saving / standard time happen in connection
with the charge APP.
 See table "Functional description for operating mode
time-controlled (internal)" on page 13.
Operating mode "External Tariff Signal"
In this operating mode, the charging process is controlled
over an external contact (such as a ripple control receiver).
In addition, the available charging current can be adapted to
various main / off-peak tariffs as in operating mode "Time-
Controlled"
 See table "Functional description of operating mode
External Tariff Signal" on page 14.
Operating mode "Energy Manager"
In this operating mode, the charging process is controlled
over the SUNNY HOME MANAGER
The charging station is connected to the SUNNY HOME
MANAGER over LAN / WLAN. Both devices must be on the
same network.
The SUNNY HOME MANAGER then controls the charging
power depending on the energy generated by the
photovoltaic system and user preferences.
 See table "Functional description of operating mode
Energy Manager" on page 15.
Operating mode "SCU"
In this operating mode, the charging process is controlled by
a higher-level back-end system (such as MENNEKES E-
Mobility Control Panel).
The charging station is connected to a MENNEKES ACU over
RS485.
In operating mode SCU, control over Charge APP or
switching to other operating modes is not possible.
 See table "Functional description of operating mode
SCU" on page 16.
