AUTOMATIC OPERATION

Pump switch-on
Whenever water comes into continuous contact with both sensors for longer than 5 seconds, the bilge
pump switches on.
Pump switch-off
When one or both sensors are no longer in contact with water for longer than 5 seconds, a 15 second pump
switch-off period will begin. After this period has elapsed, the pump will switch off.
Battery save function
Whenever the power supply falls below 9V DC (for 12V DC systems) or is in the range of 15V and 20V DC (for
24V DC systems), the EBSN will not permit bilge pump switch-on.

MANUAL OPERATION

Manual pump switch-on
This button (optional) permits the bilge pump to be switched on manually. Pressing this button for more
than 1 second and then releasing it switches the bilge pump on. In the same way, if the button is pressed
again, the pump will switch off. After 8 minutes of continuous operation, the pump switches off automati-
cally and the EBSN returns to automatic mode.
NOTIFICATION SIGNS
The following signals are provided only if the led or the remote control panel has been installed (optional).

DESCRIPTION
Battery save function. Whenever the power supply falls below 9V DC (for 12V DC systems)
or is in the range of 15V and 20V DC (for 24V DC systems), the EBSN will not permit bilge
pump switch-on. Check both the level of charge of the batteries and the correct sizing of
the power supply cables.
Prolonged pump working condition.
The sensor will continue signalling the presence of water for 8 minutes after switch-on.
This signal may indicate:
• normal system behaviour
• a problem linked to the correct working condition of the pump
• the need to service the EBSN
• prolonged presence of water where the EBSN is installed
