The microprocessorsends a signal to the column circuit causing the output of the UNL-2803 to toqqle,
When point "A" drops low, the T[P107 transistor conducts and point "B" changes to a high state, At the
same time, the microprocessor drives the input of the 74LS74 [ow, causing a high at output "F". A high
state at the base of the TIP102 causes the transistor to conducts, bringing the row circuit to ground and
turning the [amp on. The microprocessor changes the input of the 74LS74 to a high state to turn the [amp
off. In overcurrent conditions, the lamp is shut off through the comparator.
If the voltage at the negative
input of the LM339 rises above 1.4V, the output changes to a low, which is fed back to the 74LS74 and
shuts the circuit off.
