switches in CZone for the battery chargers: Batt Charger Port, Batt Charger Stbd, and Batt Charger
Thruster� The battery chargers have a built in isolator that sense the charging needs of the batteries
and distributes charge accordingly� At the point that the batteries are nearly fully restored, the
battery chargers will automatically reduce the current being sent to the batteries to a maintenance
level� See the battery charger manuals in your owner’s packet for further information�
Battery Select Switch
The battery select switch panel is located directly below the aft rigging lid on the forward side of
the rigging compartment� There are 7 Battery Select switches on the panel� There is a switch for
each of the engines and one for the house bank� To start the engines, the four engine select switches
must be turned to the on position� These switches can all be turned on remotely through the CZone
key fob by pressing the number 2 button on the fob� The house battery select switch must be on to
operate any CZone feature as well as the switches on the helm instrument panel� This switch can be
turned on remotely by pressing the number 1 button of the CZone key fob� In addition to the engine
and house switches, there are two emergency parallel select switches for the engines� To use the
emergency parallel switches, turn on the battery switches for each motor and then manually turn on
the emergency parallel� These switches should only be used in emergency situations and should be
returned to their off position after starting the engines� Note: Due to the fact that these switches can
be turned on remotely, the switches have motors that drive them in both directions� To turn on the
switch manually, depress the switch and then turn to prevent damage to the motor�
C A U T I O N
Never turn the battery select switch to the “off” position with an engine (including generator)
running as this could damage the engine charging system or the generator control panel.
Bilge Pump/Float Switch
Your boat is equipped with automatic float switches adjacent to the bilge pumps� The float
switch will enable the pump to come on automatically if a significant amount of water accumulates
in the bilge� The float switches function independently of the battery select switches and can
activate the bilge pump with the battery select switches in the “off” position� The bilge pumps are
also equipped with switches at the helm� When a switch is in the “on” position, the pump will run
continuously� When a switch is in the “off” position, the pump is off unless activated by the float
switch� Bilge pumps should not be left on unless someone is monitoring the system and can turn
the pump off when the bilge is dry�
C A U T I O N
To prevent damage to the bilge pump, do not run it dry for a prolonged period of time.
