We recommend connecting OPTISWITCH 5200 C, 5250 C in such a
way that the switching circuit is open when there is a level signal, line
break or failure (safe state).
For connection to a VEGATOR controller dto. Ex, WHG. The sensor is
powered by the connected VEGATOR controller. Further information
is available in chapter "Technical data", "Ex-technical data" are avail-
able in the supplied "Safety information manual".
The wiring example is applicable for all suitable controllers.
The control lamp on OPTISWITCH 5200 C, 5250 C lights in general
•
red - with covered tuning fork
•
green - with uncovered tuning fork
Take note of the operating instructions manual of the controller. Suit-
able controllers are listed in chapter "Technical data".
If OPTISWITCH 5200 C, 5250 C is used in Ex areas as part of an
overfill protection system according to WHG (Water Resources Act),
take note of the regulations in the safety instructions and conformity
certificates. If the instrument with electronics module SWE60Z EX,
SWE60Z EX E1 is to be operated directly on the analogue input of a
PLC, a suitable safety barrier should be connected.
