Operation
After connection to the battery the green LED lights up and the switch is
operative. When the water level inside the hull reaches the two sensors of the
switch, the LED goes off. If sensors remain in contact with water for at least 12
seconds consecutively, the pump starts up.
The LED will light up again when the water level goes below the sensors; the
pump will stop with a 30 seconds delay after the LED goes on, to permit the
complete drainage of bilge.
The switch is provided with overheating protection, with intervention
approximately at 55°: the red LED turns on and the pump stops. Restart is
automatic when switch temperature is approximately less than 35°.
Warning
TO KEEP
CONDITIONS THE TWO SENSORS MUST BE CLEANED
PERIODICALLY.
Note
THE SWITCH DOES NOT DETECT THE PRESENCE OF
OIL, DIESEL OIL OR OTHER LOW CONDUCTIVITY
LIQUIDS.
