• Magnetic Latch (ML)—draws very low current (<10 mA to monitor terminal voltage) in the
ON or OFF states, and draws moderate current for very short time when changing state
• Start Isolation (SI)—can be configured for temporary isolation of House loads from Engine circuit during
engine cranking to protect sensitive electronics
• Engine Isolation (EI)—can be configured for isolation of two engines while both are running to protect
engine electronics and maximize alternator output
• Senses charging on two battery banks
• LED output to remotely indicate when batteries are combined or isolated
• Tin-plated copper studs for maximum conductivity and corrosion resistance
• Label recesses for circuit identification
• Silver alloy contacts provide high reliability for switching live loads

Overview of Application
The ML-Series ACR automatically combines batteries during charging, and isolates batteries when there is no
charging sensed on either battery bank.
ML-Series ACR Function 12 Volt DC Operation 24 Volt DC Operation
Automatically combines battery
banks when sensed voltage
levels are:
Above 13.5V for 30 sec.
Above 13.0V for 90 sec.
Above 27.0V for 30 sec.
Above 26.0V for 90 sec.
Automatically isolates battery
banks when sensed voltage
levels are:
Below 9.6V (undervoltage lockout)
Below 12.35V for 10 sec.
Below 12.75V for 30 sec.
Above 16.2V (overvoltage lockout)
Below 19.2V (undervoltage lockout)
Below 24.7V for 10 sec.
Below 25.5V for 30 sec.
Above 32.4V (overvoltage lockout)
Start Isolation or Engine Isolation. The isolation inputs enable one of two functions depending on
how the inputs are configured.
NOTE: The ML-Series ACR can be configured for Start Isolation or Engine Isolation, but not both.
• Start Isolation - Temporary isolation (3−5 minutes) of house loads from the engine circuit during engine
cranking to protect sensitive electronics. Configure Start Isolation when there are heavy cranking loads
causing sags and spikes that might damage electronics in the House circuit. See page 3.
•
Engine Isolation - Isolate two engines while both are running to protect engine electronics, and to
maximize alternator output. Configure Engine Isolation when the engine manufacturer requires it, and
when there are separate batteries for each engine. See page 3.
Undervoltage or Overvoltage Lockout.
• Undervoltage lockout prevents batteries from being combined when either battery is below 9.6V@12V DC
operation or 19.2V@24V DC operation.
• Overvoltage lockout prevents batteries from being combined when either battery is above 16.2V@12V DC
operation or 32.4V@24V DC operation.
Control Switch Remote Operation. Optional Contura Control Switch—sustained (SPDT) ON-OFF-ON.
The Control Switch should be mounted in a convenient location near helm controls to allow for quick access.
NOTE: Alternatively use a momentary (SPDT) (ON)-OFF-(ON) or momentary push button switch to provide cross connect and/or battery isolation.
To cross connect
(combine) battery banks
Switch to “ON” combines battery banks to provide more battery power in hard
starting situations.
To isolate battery banks
Switch to “OFF”- when the battery banks are isolated using the Control
Switch, the battery banks remain isolated, and for at least 30 seconds after
the control switch is returned to the “AUTO” position.
Control Switch Remote Indication or ML-ACR Status
NOTE: The remote switch has two LEDs (top and bottom). These LEDs operate simultaneously-either they are both ON or both OFF.

LEDs OFF
Batteries are isolated

LEDs slow steady blink, ON-OFF Start or Engine Isolation is causing batteries to be isolated
LEDs quick steady blink, ON-OFF

after remote switch is returned to “AUTO”
