NOTE

Many of the signals listed in the PCB information to

follow will be low voltage signals that will be in one

of two states: +12VDC (High) or 0VDC (Low) with

respect to PCB common. When a signal name is

preceded by the “/” mark, it denotes that the signal

is an active low. For example:
/OVERTEMP – This signal is normally High but

when an over temperature fault exists, this line will
change state to a Low.
