OPERATION:
Power activated from control panel:
The outputs for internal lights (lights_1 and lights_2), external light, pump are activated directly by

-If the service battery voltage remains under 10V for over a minute, the NE185 shunt
automatically turns off all the power for lights, pump. To recharge press the relevant keys on the
control panel. If the battery is still under 10V, it will be deactivated again after one minute.
