Characteristics
• used to control the level in wells, reservoirs, tanks, pools, tankers, containers, etc.
• within the framework of a single device, the following confi gurations can be selected
(see functions graph):
- two separate level switches
- two probes in one tank
- fi lling tank from well
• single-state monitors one level (full or empty tank), double-state monitors two levels
(switches on upon one level and switches off upon the second)
• DIP switch on front panel is used to choose function (see functions graph):
- pumping in
- pumping out
- over-pumping
• option of setting time delay for reacting to the output upon a change in level, any type
of delay by DIP switch
• sensitivity adjustable by potentiometer (probe resistance based on fl uid)
• the measuring frequency 500 Hz prevents fl uid polarization and oxidation increase of
measured probes
• galvanically separated supply AC 110 V, AC 230 V or AC/DC 24 V
• output contact 2x switches 16 A / 250 V AC1
• 3-MODULE design, mounting onto DIN rail
