A1
LACK OF WATER
Fault message:
LED "FAILURE" FLASHES (FAULT).
Fault message after acknowledgement:
LED "FAILURE" ILLUMINATED (FAULT).
If the automatic control unit detects a
lack of water at the automatic control
unit inlet for more than 10 seconds, the
pump is stopped and the ART logic is
triggered.
The ART logic restarts the pump
after 5 minutes and 30 seconds
have lapsed to reinstate the
function.
If there is still a lack of water,
the automatic control unit
restarts the function every
30 minutes over a period of
24 hours. If the system still
detects a lack of water after
several repeat attempts, the
pump is stopped permanently
until the fault has been
rectified. No water is present at the inlet
and the safety system was
triggered as a result: Check the
water supply inlet. The pump
can be filled with water by
pressing the START/STOP button
(the AUTO On/Off LED should
not illuminate; if this is the case,
deactivate the LED by pressing
the button).

LEVEL
Fault message after acknowledgement:

If a float is installed in the inlet tank,
the float switch immediately stops the
pump as soon as a lack of water is
detected.
The system then outputs a lack-of-water
message (A1).
The pump remains stopped until
the fill level sensor detects
water in the tank again. Check tank.
