Load Management (Only Basic 22 / S 22) - Mennekes Basic 3,7 Operating And Installation Manual

f If present, connect external signal transmitters to the
relay:
KF1 = charging point left side,
KF2 = charging point right side.
Î "4. Technical Data"
External signal transmitters must be interconnected to
the respective relay with 230 V AC (optionally possible:
12 V DC or 24 V DC).
„ Terminal block XT opened - release only via continuous
signal: Ending the charge through external shutdown is
possible. The key-operated push-button has no function
in this mode.
„ Terminal block XT closed - release only through pulse
signal: Latched charging, shutdown on the vehicle. No
external shutdown possible. In this mode, the key-ope-
rated push-button may be used for authorisation, as the
key likewise sends a pulse signal when actuated.

5.9 Load management (only Basic 22 / S 22)

The charging systems Basic 22 and Basic S 22 have sim-
ple load management Load management can be activated
at installation as needed.
If only a limited connected load is available, distribution to
the individual charging points must be regulated, to ensure
adequate supply of both charging points. Load manage-
ment handles this task easily and conveniently. If only one
vehicle will be charged, then the full charging current is
available. If an additional vehicle is added, it is possible
that the available connected load will be exceeded. In this
case load management intervenes.
For example, at a connected load of 22 kW, it is possible
to operate one charging point with 22 kW or both charging
points with 11 kW. Adaptation occurs automatically with acti-
vated load management. Through this measure exceeding
the available connected load and tripping the back-up fuse
are avoided.

Switching on load management
The charging systems Basic 22 and Basic S 22 have sim-
ple load management that can be activated as needed. In
delivery status this is deactivated; it can be activated via
disconnect terminals XT3 and XT4.
XT3 opened: Load management is active on charging
point 2.
XT3 closed: Load management is not active on charging
point 2.
XT4 opened: Load management is active on charging
point 1.
XT4 closed: Load management is not active on charging
point 1.
The following configurations can be set with terminals XT3
and XT4:
XT4 opened
XT3 opened LP1 = 22/11 kW
LP2 = 22/11 kW
XT3 closed LP1 = 22/11 kW
LP2 = 22 kW
LP1 = charging point 1 (left)
LP2 = charging point 2 (right)
XT4 closed
LP1 = 22 kW
LP2 = 22/11 kW
LP1 = 22 kW
LP2 = 22 kW
