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 contactor
and brake coils. On command from the control card,
these drivers initiate opening and closing the 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.
