5.2.1.6 Control Pilot (CP) and Proximity Pilot (PP) connections
The Control Pilot (CP) and Proximity Pilot (PP) contacts connect the charge controller to
the outlet, enabling it to communicate with the vehicle and the cable plug. The CP and
PP contact allow the charge controller to determine whether a cord has been plugged
into the socket (proximity) and to inform the vehicle about the amount of power it can
draw (refer to IEC 61851).
5.2.1.7 I/O extension
The CC612 has additional I/O interfaces available via a configurable 3-channel I/O inter-
face (connector C: 21, 24, IN1-, IN1+, IN2-, IN2+) that can be used for multiple purposes,
for example:
• Parking management interface (The supported communication protocol is proprie-
tary to Scheidt & Bachmann and based on the available auxiliary relay and one
available input)
• Additional household main socket outlet control
• Power outage monitoring (e.g. RCD trip monitoring)
• Cooling fan switch for over-temperature control
• Connection to a meter with an S0 interface
5.2.1.8 RDC-MD (Residual Direct Current Monitoring Device)
Current Transformer (CT) connection (device variant)
For AC charging system fault monitoring, a charge controller variant is available which
features an integrated RDC-MD which works with an external magnetically shielded me-
asuring current transformer (CT) connected to the CC612. This allows the use of a type A
RCD in the charging system instead of the more expensive type B RCD. The relay in the
CC612 triggers if, during charging, the fault current limit I
Δn
≥ DC 6 mA.
The CP terminal is used for Power Line Communication (PLC) in charge
controller variants with this optional integrated feature.
5.2.1.9 Plug lock connection
Under normal operating conditions, the type 2 socket automatically locks the plug when
a vehicle is connected to the charging system. The locking action can be heard. After
disconnecting the plug from the vehicle, the charging system socket automatically
unlocks the charging system socket and the cable can be removed. If both locking and
unlocking work, the socket was correctly attached to the charging system controller. Via
terminals IN , +, OUT, - (i.e. plug lock connections), the charge controller can interface to
different socket/actuator types. Type 2 sockets from various manufacturers and their cor-
responding connection to the charge controller are shown below:
