We recommend connecting OPTISWITCH 3000 C in such a
way that the switching circuit is open when there is a level
signal, line break or failure (safe condition).
The contactless electronic switch is always shown in non-
operative condition.
The instrument is used for direct control of relays, contactors,
magnet valves, warning lights, horns etc. It must not be
operated without an intermediately connected load, because
the electronics would be destroyed if connected directly to the
mains. It is not suitable for connection to low voltage PLC
inputs.
Domestic current is temporarily lowered below 1 mA after
switching off the load so that contactors, whose holding current
is lower than the constant domestic current of the electronics
are reliably switched off.
