Description of controller
The following illustrations should be viewed only as schematic diagrams showing the
respective hydraulic systems and do not claim to be complete. The controller does not
replace safety devices under any circumstances. Depending on the specifi c application,
additional system components and safety components may be required, such as check
valves, non-return valves, safety temperature limiters, scalding protectors etc. and must
therefore be provided.
Programme 1
Level controller with safety shutdown
Programme 3
Level controller
Programme 5
Level controller with safety shutdown and water
detector sensors.
The water level between the highest two level
switches will be maintained. The lowest level switch
serves as protection against dry running.
Programme 2
Level controller with safety shutdown and 3 water
detector sensors
Programme 4
Level controller with 3 water detector sensors
Programme 6
Level controller with water detector sensor.
The water level between the highest two level
switches will be maintained. The lowest level switch
serves as protection against dry running.
