Manual

You can find the
electrical connection of VEGATOR 631 Ex in the
operating instructions manual of the corresponding signal conditioning
instrument.
Line monitoring
With Ex versions, this 220 kΩ resistor is already integrated ex factory in
the connection housing of the probe. The Ex measuring system (max.
and ground connection cable of the probe to the signal conditioning
instrument) is generally monitored for line break.
You can set mode A or B by means of the selection switch.
Mode A
Preferrably a s overflow protection, compulsory as overfill protection.
