W e recommend connecting LFV
330
in such a way that the switching
circuit is open when there is a level signal
,
line break or failure
(
safe
condition
).
I
nformation
:
T he contactless electronic switch is always shown in non
-
operative
condition
.
W arning :
T he instrument must not be operated without an intermediately
connected load
,
because the electronics would be destroyed if
connected directly to the mains
.
I t is not suitable for connection to low
voltage PLC inputs
.
F or direct control of relays
,
contactors
,
magnet valves
,
warning lights
,
horns etc
.
D omestic current is temporarily lowered below 1 m A after switching o
ff
the load so that contactors
,
whose holding current is lower than the
constant domestic current of the electronics
,
are reliably switched o
