We recommend connecting VEGAVIB 63 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.
Warning:
The instrument 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.
Examples for typical applications:
Load resistance at 24 V DC: 88 ... 1800 Ω
l
Rated power, relay 253 V AC: > 2.5 VA
l
Rated power, relay 24 V AC: > 0.5 VA
l
For direct control of relays, contactors, magnet valves, warning lights,
horns etc.
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.
When VEGAVIB 63 is used as part of an overfill protection system
according to WHG, also note the regulations of the general type
approval.
