DUAL SENSING MODELS WIRING DIAGRAM
Dual Sensing Smart Start
®
SBIs or 'D'
Series SBIs monitor both the start battery
and the auxiliary. If the unit detects that
either battery has exceeded 13.2 V the
isolator will be connected. Dual control
provides the benefit of being able to
charge the main battery from a solar
panel or battery charger on the auxiliary
battery.
The SBI12D has the added feature of
allowing charge both ways.
*When using fuses make sure that
the fuse makes a good low resistance
connection. Circuit Breaker/Fuse ratings
are dependent on the type of installation
and the size of the loads.
FAULT INDICATION
NOTE: The LED may stay ON for a period after the vehicle is turned OFF.
This is NOT a fault. Should a fault occur, the Smart Start
the operator of the fault. The LED will flash repeatedly with the following
sequences:
CODE 1
2 Flashes
Over-Voltage
CODE 2
3 Flashes
Voltage Drop or Excessive Current Draw Fault
Fault Code 1:
If the batteries connected to either terminal of the Smart Start
rise above 15.5 V (31 V on a 24 V system), the Smart Start
following:
ƒ Disconnect, if connected. This is to prevent the source of over-voltage
reaching the other battery.
ƒ Flash the LED 2 times for 20 seconds, then reassess the fault condition,
continuing until the fault is cleared.
Fault Code 2:
If the Smart Start® SBI detects a voltage drop across its contacts of greater
than 1 V for more than 30 seconds then the unit will:
ƒ Immediately protect itself by disconnecting the auxiliary battery; and
ƒ Flash the LED 3 times for 20 seconds, then reassess the presence of a
fault, continuing until the fault is cleared.
FREQUENTLY ASKED QUESTIONS
Why does the LED stay on after the vehicle is turned off?
The LED stays on (indicating the Smart Start
linked) until the voltage drops to 12.7 V (25.4 V for SBI24). This can take a few
minutes to many hours, depending on size and state of charge of the batteries
as well as load on the batteries. To test this feature of the Smart Start
sure the engine is turned off, then turn the headlights On. The Smart Start
LED should turn Off; this may take a couple of minutes.
Is the unit protected against voltage spikes?
Yes, the Smart Start
SBI incorporates a number of spike protection
®
components specifically designed to reduce the risk of damaging the unit.
The Smart Start
®
SBI is also designed to prevent any spikes generated by the
solenoid coil from affecting any vehicle equipment.
What does the red LED indicate?
The red LED indicates the solenoid is activated and both batteries are
connected together and therefore are both being charged simultaneously. A
flashing red LED during operation indicates a fault.
We are experiencing repetitive switching of our Smart Start® SBI. What
could be causing this?
This can occur for one of two reasons. Firstly, switching a poorly charged
second battery into the system loads the voltage at the Smart Start
below its lower voltage limit, which will cause the Smart Start
back off.
Secondly, voltage drop due to cable length (Smart Start
far from start battery) can cause the voltage at the start terminal on the Smart
Start
SBI to be lower than at the start battery, which can also cause the unit
®
to switch off. Voltage seen by the Smart Start
the Smart Start
SBI switches back on. This switching will continue until the
®
cause of voltage drop is removed. On and Off Time delays are built into the
product to avoid the solenoid contacts chattering in this scenario.

CHECKING THE OPERATION
Once the Smart Start
SBI is installed follow the steps below to check your
®
operation:
1. Start the vehicle or apply a charge to the start battery.
2. Once the start battery voltage rises to the 'ON Volts' level the Smart Start
SBI will activate, you will hear the solenoid click and see the LED illuminate.
3. Now turn off the vehicle or remove the charger from the start battery. The
Smart Start
SBI will disconnect the auxiliary battery once the voltage on
®
the start battery drops to the OFF Volts level, you will hear the solenoid
click and the LED will turn off.
NOTE:
ƒ The amount of time it takes for the battery voltage to drop low enough for
the solenoid to turn off will vary due to the battery condition, age and state
of charge (for a new, fully charged battery, it may take days).
ƒ Check the specification table of your Smart Start
voltage levels.
ƒ As per above, the LED may stay ON for a period of time after the vehicle
is turned OFF.
Does the internal LED illuminate when I use the external override switch?
Yes.
Can the voltage limits and time delay settings be changed?
Yes. Both upper and lower voltage limits & on and off times can be changed.
However, this needs to be done at the time of manufacture and will incur a
relatively minor cost.
Can I use the Smart Start
SBI to control a load (e.g. fridge) without using
®
an auxiliary battery?
Yes. The voltage monitoring is done on the start battery side of the unit. If a
load is connected on the auxiliary side instead of a battery, the unit will still
operate when the start battery is charged, providing power to your load.
Can I use my Smart Start
SBI to winch off both batteries?
®
Yes. We recommend that the Smart Start
connects both batteries when the winch is turned on, through use of the Start
Assist feature on the override wire. We also recommend the use of our 200 A
Smart Start
SBI for this application.
®
Can I use the Smart Start
SBI on a positive chassis vehicle?
®
Yes. Please contact REDARC for further information.
