Electronic Charging Control Unit Behaviour In Case Of Fault - AEG WSP 1210 F Gebrauchs- Und Montageanweisung

For the Fitter
2.2.3 Electronic Charging Control Unit
Behaviour in case of fault
The charging control unit in the device is set at the factory to "positive fault behaviour (80 % PS),
i.e. in the case of a defective charging control unit (e.g. failure of the control signal), the unit is
fully charged.
The unit can be switched to "negative fault behaviour" (no charging of the storage heater) by
moving the plug-in bridge X16 to position "80 % NS" when the device is connected to a digital
charging control unit.
Operation with the charging control unit
The appropriate notes in the operating and installation instructions of the charging control unit
must be observed.
Control signal
The electronic charging control unit can be connected to different control signals (ED) of control
units and can therefore be integrated in existing systems.
It is factory set to an AC control signal (AC voltage signal at terminals A1/A2) with 80 % ED.
By moving the plug-in bridge X16, other ED signals (68/72 %, 37/40 %) can be selected. This is
necessary when the unit is integrated in an already existing system which controls the charging
with one of the named ED signals.
Connection to DC control signal (X3) (see circuit diagram page 19)
If a charging control unit with DC control signal (DC voltage 0.91 V-1.43 V) is installed in the
system, the control signal must be connected to the control terminals covered at the factory
"DC +" (plus pole) and "DC-" (minus pole) (Pay attention to polarity!).
The 230 V AC control signal may not be connected to the "DC +" and "DC –" terminals. The
charging control unit would otherwise be destroyed.
