parameters.
Section 2.3.7 Circuit Board Coil Driver Modules
Coil drivers are internal to the control card, and are the
power devices that operate the Line, 1A and SP contactor
coils. On command from the control card, these drivers
initiate opening and closing the contactor coils. All driver
modules are equipped with reverse battery protection, such
that, if the battery is connected incorrectly, the contactors
can not be closed electrically.
