Function
Low Voltage Cut off – Engine off: The system
will disconnect power when voltage is sensed
below the mode threshold value (11.74V or 12.2V).
The system will only disconnect if the low voltage
is below threshold for 60 seconds continuously.
The system will keep the relay contacts open until
a key cycle occurs or a voltage increase is
detected (for example: an external charger
applied) above the low set point threshold.
External Charger – Engine off: The system will
close the relay contacts if a voltage over 13.1V is
detected in the system (an external charger is
added to the Ford or third party battery) for 8
hours to provide a charge to all batteries in the
system. Manual override can be done by keeping
Immediate Relay Close Pin grounded during the
period when continuous power is required. A third
party fit latched switch type would achieve this
functionality. When a low voltage condition is
detected on Ford battery system in modes
2,4,6,8,10, relay will not be opened if third party
battery system has voltage higher than defined
threshold.
Low Voltage Cut off – Engine on: The system
will close the relay contacts when an engine run
is detected and the voltages prior to crank event
was higher than the threshold value. An SRC
Inhibit request is sent, 5 seconds before closing
the relay contacts if the converter battery voltage
is detected lower than the threshold value. This
allows time for the alternator to ramp up to full
charge voltage. Isolation of the relay, will occur
immediately when the ignition signal is detected,
if a mains charger is connected to the system prior
to the crank event. A warning will also be given
via the Status Indicator circuits. It is up to the
converter as to decide whether third party visual
or audible warning devices are fitted to the signal.
Load Active Input - Engine off: Load Active
Input allows longer Engine Off usage at currents
above 20A by reducing the cut off voltage
threshold of the Modes. When the Load Active
Input is turned on the cut off threshold is set 0.3V
lower than the actual Mode threshold. This feature
has a dual function, it is also used as SRC Inhibit
at Engine Run, therefore, when the engine is
running, the function of the Load Active will end
and SRC will start. At Engine Off, when the input
is applied whilst load is active, a new threshold
will be set and relay will stay connected until the
new threshold is reached. For Example: Mode 7
has 11.8V Mode threshold value. If the Load Active
Input is activated at Engine Off, the new threshold
will be 11.5V. The user can continue using battery
power until voltage goes below 11.5V. This is the
closed circuit voltage under loads above 20A,
therefore when the cut-off happens, open circuit
voltage will be observed to recover. The lower
calibration is required to compensate for load
versus actual battery state of charge. To reduce
the risk of early Power disconnect, the load feature
must be utilized for peripheral continuous loading
above 20A. Repeat usage of this function without
charging the batteries will lead to shorter usage
duration and may lead to a failed crank.
