The HC controller controls the charging process in a fully
automatically and performs the following functions:
 Communication with Charge APP over WLAN.
 Communication with service interface over WLAN / LAN.
 Analysis of the data from a connected meter.
 Analysis of the monitoring system's data
 Detecting the current-carrying capacity of the charging
cable with resistance coding. Unsuitable charging cables
are rejected.
 It checks that the requirements for proper charging have
been met.
 Querying an external signal (tariff switching).
 It uses the CP contact to communicate with the vehicle.
Using a PWM signal, the charging current upper limit is
transmitted to the vehicle. The ground conductor
connection is checked at the same time.
 Controlling the locking of the charging plug in the
charging socket (for devices with charging socket Type
2).
 Controlling the charging contactor.

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 32.
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 33.
