Assembly
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 sliding switch is used to assign the valve groups (4 or
8 valves) (see "Selecting the valve supply" on page 72). This
enables e.g. a separate switch-off.
The load supply cable must fulfill the following requirements:
W
Cable socket: 4-pin, A-coded without center hole
Cable cross-section:  0.5 mm

Length: Max. 20 m
W
Both voltage supplies (pin 1, pin 2, see Tab. 5) must be
protected by an external fuse (3 A, F).
Dangerous voltages
A power pack without safe isolation may lead to dangerous
voltages, which may result in injury from electric shock or
system damage.
O
Only use a power pack with safe isolation according to
EN 60747, classification VDE 0551. This ensures that the
electric circuits comply with SELV/PELV electric circuits
in accordance with IEC 60364-4-41.
Total current is too high
The currents from the sensor and valve line (each max. 3 A)
are summed up. If the total output of the 0 volt line is greater
than 4 A, the plug and conductors of the device will be
overloaded.
O
Design the DDL system so that the total output of the
0 volt line is less than 4 A.
