CORRECT
Operating modes for variants AC and
DC-PNP
The LVL-A1 can be connected in two operating
modes. Depending on the operating mode
selected (MAX or MIN safety), the LVL-A1 will
switch off safely in the event of a fault (e. g. if the
power supply line is interrupted).
MAX – maximum fail-safe mode
• The LVL-A1 keeps the electronic switch closed
as long as the fluid level is below the fork.
• Example application: overspill protection
MIN – minimum fail-safe mode
• The LVL-A1 keeps the electronic switch closed
as long as the fork is immersed in fluid.
• Example application: dry running protection of
pumps
The electronic switch opens if the limit is reached,
if a fault occurs or in the event of a power failure.
For the meaning of the light indications, see
page 28.
