Connecting the power supply on the
bus coupler
The bus coupler electronics are supplied by the DDL (X71). Two
external power supplies (24 V) can be supplied to the valves via
the X10 (POWER) plug. When connecting the external valve supply
of the bus coupler, ensure pin assignment according to Tab. 6.

There is no galvanic isolation between the voltages for the
bus coupler and the external power supplies U
The 0 V lines are connected to each other. The supply voltage
must come from the power pack that also supplies the bus
coupler!
W
With the valve supplies U
the DDL cable, it is possible to control the valves byte by byte
(each byte represents 4 double solenoid or 8 single solenoid
valves).
W
The S1 - S4 sliding switches are used to assign the valve
groups (4 or 8 valves) (see "Selecting the valve supply" on
page 90). This makes it possible to e.g. disconnect two
separate voltages.
The load supply cable must fulfill the following requirements:
