To adjust the airflow ventilation rate

, determine the "FLOW
INDEX" needed for the intake and exhaust blowers for
the CFM require
d
.
After determining the air volume
rates needed for the intended
application (Maximum &
Minimum), the table
immediately to the left will allow
for you to program your CO2
control output voltages in
correlation to the CO2 levels you
wish to control when Bard Part #
8403-067 CO2 Control is applied.
1.> Locate two 0-10Vdc Motor Control Boards in control panel
2.> On intake Motor Control Board, observing "GREEN STATUS
LIGHT", turn manual adjust potentiometer (with a small phillips-head
screwdriver) "CCW" to increase "FLOW INDEX" or CW to reduce
"FLOW INDEX" to match desired setting.
(NOTE: After long pause,
the green status light will blink long-blinks for the "TEN COUNT" of
the "FLOW RATE INDEX", which then is immediately followed by
fast blinks which indicate the second digit. For example, a Flow
Index of 23 would be two long blinks, followed by
three
fast
blinks of the "GREEN STATUS LIGHT".)
3.> On exhaust Motor Control Board, observing "GREEN STATUS
LIGHT", turn manual adjust potentiometer (with a small phillips-head
screwdriver) "CCW" to increase "FLOW INDEX" or CW to reduce
"FLOW INDEX" to match desired setting.
(Same GREEN STATUS
LIGHT blink (refer to Step #
2
))
