4.5 Engine detection override
In charger mode the "engine on detection sequence" determines
if conditions are met to enable charging, see chapter 5. The
"engine detection override" forces the charger to allow charging
independent of the engine on detection. Engine detection
override is activated by applying >7V to the remote L-pin. This
allows external control (e.g. ignition switch, CAN bus engine on
detector) to enable charging.
This function does not override the remote function. Therefore,
remote connection a), b) or d) must be configured in combination
with engine dection override. See examples in figure 4.
