Blue Sea Systems 7701 ML Solenoid - 12V DC User Manual
Overview of application, Ml– series, Remote battery switches
The ML-Series Remote Battery Switch/Solenoid Switch provides high-current carrying and
switching under load. The Remote Battery Switch/Solenoid Switch is installed close to the battery banks.
A single pole double throw (SPDT) Control Switch Panel, or two momentary push button switches, operate
the Remote Battery Switch/Solenoid Switch. Control Switches are installed in a convenient location near
other electrical controls or companionway (see Illustrations on reverse).
The Manual Control Override Knob provides
(Remote Battery Switch Only)
:
• an added level of safety that allows manual ON-OFF control with or without power
• LOCK OFF for servicing the electrical system
A remote LED (sold separately) indicates a closed connection between battery bank and load, or between
two battery banks when used as an emergency cross-connect.
Remote Operation. The momentary (SPDT) (ON)-OFF-(ON) Remote Control Contura Switch can
provide cross connect and/or battery isolation. The Control Switch should be mounted in a convenient loca-
tion near helm controls to allow for quick access.
Emergency Manual Control Override Operations
(Remote Battery Switch Only)
* If the Control Switch is held ON or OFF for 5 seconds, the internal coil protection will engage and the
Remote Battery Switch/Solenoid Switch will not respond to further remote input for approximately
10 seconds.

• Magnetic Latch—draws no current in ON or OFF state, only draws current when changing state of switch
• Silver alloy contacts provide high reliability for switching live loads
• Manual control override knob provides an added level of safety allowing control with or without power, and
offering LOCKED OFF capability for servicing (Remote Battery Switch ONLY)
• LED output to remotely indicate switch state
• Tin-plated copper studs for maximum conductivity and corrosion resistance
• Label recesses for circuit identification

Overview of Application
To connect battery bank to load, or combine
battery banks
Momentarily depress control switch actuator to “ON”.
Remote LED indicates closed connection.*
To disconnect battery bank from load, or
isolate battery banks that are connected
Momentarily depress control switch actuator to “OFF”.*
To connect battery bank to load,
or combine battery banks
With Override Knob in (REMOTE position),
push button until latched (Push to Latch On).
To disconnect battery bank from
load, or isolate battery banks that
are connected
Rotate Override Knob to right to release button
from Latch On mode (button pops up). Rotate
Override Knob to left (REMOTE position).
To prevent remote operation
Rotate Override Knob to right
(LOCK OFF position).
To secure for servicing
With Override Knob in (LOCK OFF position),
pass cable tie through hole.
