Mode of Operation
Example 1
One sensor/one level
The relay operates when the
sensor is immersed and
releases when the sensor is
no longer immersed. When
pins 7 and 8 are interconnect-
ed (dotted line), the relay is
inverted.
Example 2: Discharging
Two sensors/two levels
The relay operates when the
upper sensor (max. level) is
immersed and releases when
the lower sensor (min. level) is
no longer immersed. When
pins 7 and 8 are interconnect-
ed (dotted line), the relay is
inverted.
Example 3: Charging.
Two sensors/ two levels
In fill-up applications inverted
function (pins 7 and 8 connec-
ted) should always be used
and the pump alwalys be
supplied through pin 3 (relay
ON).
The relays releases at desired
max. level making the pump
stop. In case of power supply
interruptions, the relay releas-
es and the pump stops, thus
overflow is prevented.
Sensor characteristics
The optical sensors VP for li-
quids must not be exposed to
more than 100 lux from am-
bient light sources.
The capacitve sensors DR
and EC are for solid, fluid or
granulated substances. The
activating distance depends
on the physical and electrical
characteristics of the object
to be detected.
Note: Solid or fluid conduc-
tors are detected at a greater
distance than light or porous
insulators.
