Theory of Operation
results in an active high applied to J1-2, indicating that the sensed current is
outside the acceptable range.
Miscellaneous
Capacitors C1 and C3 are power supply bypass capacitors that act to absorb
power supply line transients. Capacitors C2 and C5 dampen any transient voltages
on the inputs of the op-amps.
