- Voltage of either battery is
≥
13.0V for 2 min.
- Relay will close, combining batteries
- Combined batteries share charge

Select an ACR that has a
CONTINUOUS
rating
above the maximum alternator output rating and
an
INTERMITTENT
rating that is above the largest
load on the auxiliary battery.

Open Voltage
- No charge present or loads exceed charge input
- Combine voltage is
≤
12.75V for 30 sec.
- Relay will open, isolating batteries
- Isolated batteries do not share charge
Under Voltage Lockout
- Charge may or may not be present
- Voltage of either battery is
≤
9.5V (ML-ACR 9.6V)
- Relay will not close even with charge on other
battery, protecting ACR and wiring from high
surge current
- Isolated batteries do not share charge
Auxiliary Battery Priority
(0ptional)
Condition: Engine running
- Open voltage is lowered to 12.25V from 12.75V
- Relay remains closed longer, combining batteries,
to allow use of auxiliary loads for a longer period
of time
Start Isolation
(0ptional)
Condition: Engine starting
- Relay is open, isolating batteries
- Batteries are isolated to protect sensitive
electronics from voltage sags and spikes
Start Assist
Condition: Engine starting – (Press Contura Switch)
- Relay is closed, combining batteries
- Batteries are combined to share power in the
event of a low start battery
Engine Isolation
Condition: Two engines are running
- One relay is open and one relay is closed
- Engine 1 Start and Engine 2 Start batteries are
isolated to protect engine electronics
- If requested by engine manufacturer
