6.5.2

Voltage Sensor Relay (VSR)

The twin voltage relay sensors are integrated into the battery switch cluster. They distribute the charging output from
the engine alternator to the “cranking” and “house” batteries. After starting an engine, the alternator sends electricity
back to the “cranking” battery to recharge it. Once the “cranking battery” is fully charged (13.6 volts), the VSR
closes to allow the alternator output to charge the “house” battery. When the VSR is operating, the LED indicator
located on the management panel will be lit. It will remain lit until the battery is fully charged, or the “cranking”
battery voltage falls below 12.8 volts. It is common for the VSR to cycle “ON” and “OFF” during operation.
However, constant cycling could indicate a problem in the system and should be checked by your dealer.

6.5.3

Emergency Parallel

In the event of a battery failure, the “EMERG PARALLEL” switch allows you to mechanically link the port
“cranking” battery to the starboard engine or vice versa. The switch should remain in the “OFF” position when not in
use. To prevent voltage spikes or drops which can damage electrical components, you cannot draw power from the
house battery using the “EMERG PARALLEL” switch.

6.5.4

24 Hour Circuits

The push-in or toggle style breakers located across the top of the management panel protect the 24 hour essential
circuit wiring. Per NMMA and USCG guidelines, these breakers are constantly energized to provide power for bilge
pumps and memory functions. This helps to protect your vessel even when you are not available. The “HOUSE”
switch does not need to be “ON” for these breakers to have power. Inspect the breakers regularly, and push-in or flip
the toggle to reset. If a breaker trips constantly, have your dealer investigate the problem as soon as possible to
prevent damage to your boat.

NOTICE

Windlasses used incorrectly could cause harm to equipment or crew
Windlasses should be used with care and treated with respect
Lewmar windlasses are designed and supplied for anchor control in marine applications and are not to be
used in conjunction with any other use.
It is the unaboidable responsibility of the owner or master or other responsible part to assess the risk of
any operation on the vessel.

6.5.5

Anchor Windlass (Optional on 250DC & 255DC & 270SD)

A 50 Amp breaker is installed at the factory for the anchor windlass; otherwise, a blank is installed on 250DC and
270SD to permit aftermarket additions. If you choose to add a windlass to your boat, contact your dealer for
information on selecting a breaker to fit the panel.

Disconnect the battery cables from the batteries prior to removing or working on the battery management
panel. Failure to do so could result in electric shock. Reference the NMMA pamphlet in your “Owner’s
Portfolio” for more information.
