Internal alarm.
Electronic communication fault. Unplug the pump from the mains and then
plug it back in pressing (+) and (-) simultaneously. Depending on the fault, the machine will
restart or remain in fault mode.
Automatic reset
5.4.
If the electronic circuit detects a fault, the pump stops and the ALARM and RUN LEDs act according to the table.
The circuit will make 4 attempts; if pressure cannot be restored due to insufficient water, the circuit will remain in
FAULT mode indefinitely, until manually reactivated. The circuit can be reset manually by pressing the (+) and (-)
buttons simultaneously.
While the pump is stopped in FAULT mode, waiting for re-attempts, the ALARM LED will blink. After 4 unsuccessful
attempts, the ALARM LED will remain lit without blinking.
The following figure shows the times that pass between the different attempts, if none of them is successful.
LEVEL SWITCH
6.
An external level switch can be installed in the suction tank. The switch must be of the float type (In15). Wiring
diagram. See fig. 2.
Never open the lid unless the power supply has been disconnected for at least 5 min.
