185 Connecting to power supplyVEGACAP 66 • - contactless electronic switch30021-EN-160331456321Fig. 10: Electronics and terminal compartment1 Potentiometer for switching point adaptation2 DIL switch for measuring range selection3 DIL switch for mode adjustment4 Ground terminal5 Connection terminals6 Control lampWe recommend connecting VEGACAP 66 in such a way that theswitching circuit is open when there is a level signal, line break orfailure (safe state).The contactless electronic switch is always shown in non-operativecondition.Warning:The instrument must not be operated without an intermediatelyconnected load, because the electronics would be destroyed if con-nected directly to the mains. It is not suitable for connection to lowvoltage PLC inputs.Examples for typical applications:• Load resistance at 24 V DC: 88 … 1800 Ω• Rated power, relay 253 V AC: > 2.5 VA• Rated power, relay 24 V AC: > 0.5 VAFor direct control of relays, contactors, magnet valves, warning lights,horns etc.Domestic current is temporarily lowered below 1 mA after switchingoff the load so that contactors, whose holding current is lower thanthe constant domestic current of the electronics, are reliably switchedoff.Electronics and terminalcompartmentWiring plan
