SITRANS LVL200H - Operating Instructions

49231-EN-170719

We recommend connecting SITRANS LVL200H according to the

closed-circuit principle, i.e. the switching circuit is open when there is

a level signal, line break or fault (safe state).

Information:

The relays (2 x SPDT) are always shown in non-operative condition.
