Initialisation of magnetic display and magnetic switch
Slowly move the enclosed oat from bottom to top on the magnetic
display and then back down again.
Align additionally mounted magnetic
switches on the basis of the same
principle. For bypass level indicators
with insulation and magnetic displays
with Plexiglass attachments, the oat
must be moved up and down inside
the tube.
For magnetic displays with purge
gas connections, these connections
must have an airtight seal. Please
refer in this case to the mounting and
operating instructions for magnetic
displays with purge gas connections
as well.
