Electrical interfacing
Supply voltage:
The supply voltage for the valve has to cover the
range of 18...30 V. The 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 valve must be free of inductive surges.
Do not exceed the max. value of 30 V Non-
observance of this rule may result in perma-
nent damaging of the valve.
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply with
overcurrent limiting feature should not be
used. Due to the inrush current of the valve
the current limit circuit may respond prema-
turely and create problems during energizing
of the supply voltage.
The operation of the valve is blocked if the
supply voltage polarity is interchanged.
Each valve requires a separate pre-fuse (rat-
ing: s. techn. data). Non-observance of this
instruction may create irreparable damage of
valve resp. incorporated system parts.
