NOTE: Install all cables securely, so that they do not become a hazard and
that they cannot be tripped over.
GETTING STARTED/FUNCTION TEST
After mounting the Water Level Switch WPS 3000 and the sensor, a function
test needs to be made.
Plug the Water Level Switch into a power socket (220....240V/AC) that is
mounted according to VDE. The “power LED” should now be on and green,
showing that the device is ready for use. Now check the function of the sensor
(without attached devices) and the function of the relay. To do this, bridge the
two metal sensors with water or conductive metal. You should be able to hear
the relay switch and the LED “Level” and ”Relay ON” should light up. When the
contacts of the relay are free again, the device will reset. Connect the pump
only after the test to avoid ”dry“ use of the pump while testing,
OPEN/CLOSE RELAY
The relay of the 230 V output can be configured as “open” or “closed”:
“Relay ON” (Default)
The basic status of the relay is “open”. The output socket has no current. The
relay will switch the output socket “ON” when the water sensor comes into
contact with water. This will then activate connected devices such as pumps
or alarms. The yellow LED “relay” and the red LED “level” will come on. Once
the sensor is not activated any more, the power output will be maintained
depending on the adjusted after-run time and then switch off. Both LEDs will
switch off again.
“Relay OFF” (Rel. aus)
The basic status of the relay is “closed”. The output socket has a current. The
relay will switch the socket “OFF” (the relay switches and interrupts the con-
tacts), when the water sensor comes into contact with water. E.g. a container
fills with water and the water flow needs to be switched off when a defined
level is reached.
The yellow LED “relay” will switch off and the red LED “level” will switch on.
When the water level falls, the red LED will switch off and the power output will
be switched on again, depending on the adjusted after-run time.
