-- Operation using 3 electrodes in "Filling" mode:
Disconnect the EH and EB electrodes from the connection
terminal strip one after another. The pump set starts up and
the red lack-of-water indicator lamp goes on.
Then, connect the EB and EH electrodes to the terminal strip
one after another. The pump set stops and the red lamp goes
out.
If the functional check does not produce the results de-
scribed above, i. e. if the red indicator lamp does not go out,
increase the relay system's sensitivity level on the potentio-
meter until there is a contact and the red lamp goes out.
8 Trouble-shooting
Disconnect the equipment from the mains prior to any assembly, dismantling or any other work on the equipment!
Each time the equipment is examined check the water level beforehand.
Faults / malfunctions
The equipment is connected to the
mains. The yellow lamp is not lit.
The pump set does not operate.
The red lamp is on (lack of water) with
the selector switch in "V" position
(Draining).
The red lamp is on (lack of water) with
the selector switch in "R" position
).
(Filling
The pump set is running but does not
deliver or the pressure is too low.
The pump set stops after a certain
operating period.
The pump sets operates intermittently.
9 Maintenance
We recommend checking the seat of the screws on the terminal
strip once a year.

Potential causes
The voltage selected on the equipment
does not correspond to the mains volt-
age.
Master switch is not engaged in "ON"
position.
The cut-in delay period has not yet
elapsed. The red indicator light flashes.
The thermal relay is not fitted correctly.
Defective connection
Fuse is not fit for operation.
Operation with 3 electrodes:
The electrodes are not immersed in the
.
water
Operation with 1 electrode:
EB is not immersed in the water
Sensitivity level has not been set.
Operation with 3 electrodes:
Electrode(s) immersed in the water.
Operation with three-phase current:
Reverse rotation.
Operation with single-phase a. c.
Defective connection of the starter.
The current rating has been set wrongly
on the thermal relay.
The EB and EH electrodes have been
interchanged.
Wrong setting of the sensitivity
potentiometer.
-- Operation using 1 electrode in "Draining" mode:
Note: During commissioning / start-up of the pump set
(master switch of control unit is set to ON) the cut-in delay
function is disenabled; the pump set immediately starts
pumping when the electrode EB is immersed in water.
Disconnect the EB electrode from the connection terminal
strip. The pump set stops and the red lack-of-water indicator
lamp goes on.
Then, connect the EB electrode to the connection terminal
strip again.
There are two potential results when the EB electrode is im-
mersed in water:
Case 1: The red indicator lamp is flashing. In this case, the
pump set will start up as soon as the cut-in delay period has
elapsed.
Case 2: The red indicator lamp is constantly on. In this case,
the relay system's sensitivity level must be increased on the
potentiometer until the red lamp starts flashing.
The pump set will then start up again as soon as the cut-in
delay period has elapsed.
Insert the fuse into the holder corre-
sponding to the mains voltage.
Flip switch to "ON" position.
Wait until the cut-in delay period has
elapsed or re-adjust (shorter period).
Check. Push red button.
Check connections
(see wiring diagram).
Replace fuse.
Lower the electrodes into the water or
wait for the water level to rise.
Lower the EB electrode into the water
.
or wait for the water level to rise.
Increase the sensitivity level on the
controller.
Remove the electrodes from the water
or wait until the water level in the tank
or well has dropped.
Interchange two phases in the control
unit.
Check the starter connection.
Check whether the current rating of the
motor matches the rating indicated on
the thermal relay.
Connect EB and EH to the correct ter-
minals of the connection terminal strip.
Set the sensitivity higher on the poten-
tiometer.
