The operation of the electronics is blocked
if the supply voltage polarity is inverted.
Each electronics module requires a separate
pre-fuse of 0.5 Amp time lag. Non-observance
of this instruction may create irreparable
damage of electronics resp. incorporated
system parts.
The screw terminals are designed to allow ter-
mination of all kinds of copper wires without the
need for preparation. Copper wire end sleeves
may usable as conductor stripping protection for
the stranded wires.
Soldering of the connection wires is not
permitted.
To ensure EMC-compatibility the wiring of the
module has partly to be undertaken by shielded
cables. Detailed information relating to this sub-
ject are available in the chapter entitled “Electri-
cal Interfacing”.
The installation should only be undertaken
by qualied personnel! A short between in-
dividual conductors, loose wires or improper
shielded connections may result in malfunc-
tion and breakdown of the electronics resp.
the connected valve!
The mounting surface of the valve must be
grounded to the machine frame. Both end
of the interconnecting cable shield must be
grounded and tied to terminal 8. It is neces-
sary to use a low ohmic potential connection
between control unit and machine frame to
prevent earth loops (cross section min. AWG
6 / 10 mm²).

Supply Voltage:
The supply voltage for the electronics is connect-
ed via terminals 1 and 2 of the module electron-
ics, the range of which is 18...30 V, residual ripple
may not exceed 5% eff.
The applied power supply must comply to
the relevant regulations (DIN EN 61558) and
must carry a CE-mark. The operating voltage
for the electronics must be free of inductive
surges. Do not exceed the max. value of
30 V! Non-observance of this rule may result
in permanent damaging of the electronics
resp. the connected valve!
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply
with “over current“ limiting feature should
not be used. Due to the inrush current of
the electronics the current limit circuit may
respond prematurely and create problems
during energizing of the supply voltage.
