to “ refill .” Then check the operation of the sensors and the circuitry without a
connected pump. A lamp is recommended to check if the circuitry is working.
FILLING A CONTAINER (MODE “ NACHFÜLLEN/REFILL ” )
– To test the circuitry, it is easiest to fill a small container or a shallow bowl of
water, and to insert the sensor 1 (Sensor min) into it. Immediately the LED
“
Sensor MIN
” will light up on the control unit. Then dip the second sensor
(Sensor Max) into the water at the same time. Immediately the LED “
Sensor
Max
” will light up, the relay will disconnect and the LED “
Rel. EIN
” should
switch off. Maximum water level has been reached, the container is filled.
– To simulate the lowering of the water level, you take Sensor 2 (Sensor Max)
out of the water. The relay remains open, the LED
“ relay on ” switches off and
the yellow LED “
Sensor MIN
” continues to shine, as sensor 1 still has wa-
ter contact. If sensor 1 is now also taken out of the water, then the relay will
switch again. This means that if a pump is attached it will be filling the con-
tainer with water.
– The relay will stay switched until the water level at sensor 2 is reached. If
water is extracted and the water level reaches sensor 1, then the unit will
switch on the pump again.
– Please do not use a pump when making dry tests, as the dry running pump
can easily damage itself.
FUNCTION MODE “ ENTLEEREN ” (EMPTY)
To reach this mode, set the slide switch to “ Entleeren ” (empty) The relay is
switched off, the yellow LED “ relay on ” is off. Then dip the contacts of Sensor
MIN into the water. The LED “ Sensor MIN ” will light up. Then dip the Sensor
Max into the water. The relay will switch on, and the LED “ relay on ” will light up
(water will be pumped) additionally the LED “ Sensor Max ” will light up.
To simulate a reducing water level, take the Sensor Max out of the water. The
LED
“ Sensor Max ” will switch off, the LED “ relay on ” and the LED “ Sensor MIN ”
will continue to shine.
Now take out Sensor MIN, indicating that the water level is below Sensor MIN.
The pump will be switched off. The LEDs
“ relay on ” and “ Sensor MIN ” are both
switched off.
