1.1.19 Fan Fault (Latching)

Pin 9 This pin is normally at +5V potential when referenced to pin 2. In the event of the fan

failing the detection circuit will shut the MicroPAC down, and illuminate the fault LED

red. Pin 9; will go from logic high to logic low level during this event. The MicroPAC will be

latched in this condition until power is removed for 30 seconds, upon reapplying

power if the fault is still persist the power supply will latch in the shut-down mode until

the fault has been cleared.

1.1.20 Ed/2 Enable/Disable Output Channel Two

Pin 10 This pin is normally at +5V potential, this enables output channel two. To disable

channel two this pin should be shorted to pin 2. If the output is disabled LED 2 will

illuminate on the LED display until the output is enabled

1.1.21 Not Connected

Pin 11 Pin 11 is not u sed

1.1.22 Ed/4 Enable/Disable Output Channel Four

Pin 12 This pin is normally at +5V potential, this enables output channel four. To disable

channel four this pin should be shorted to pin 2. If the output is disabled LED 4 will

illuminate on the LED display until the output is enabled
