CO- 8.2.0 ISOLATE VERY INTERMITTENT ACID PUMP CYCLES

Call debug screen 0. Figure (right), WITHOUT LOOKING AWAY, watch Acid versus
AAcid for one (1) minute. Are they remaining always within +/- 3 of each other?
Yes AAcid = Acid! See procedure number
No AAcid is NOT remaining within 3 of Acid! Proceed to
PUMP ERRORS...

CO- 8.2.1 AACID = ACID / ISOLATE BICARB PUMP CYCLES

Figure right, watch Bic versus ABic for one (1) minute. Are they remaining always
within +/- 3 of each other?
Yes ABic = Bic! See procedure number
No. ABic is NOT remaining within +/- 3 of Bic! Figure (right), watch the
Bicarbonate (BIC) pump's 'dot' for THREE (3) minutes. It should REMAIN
blue. TWO (2) possible scenarios:
1) IF (and ONLY if) the 'dot' is EVER white: Proceed to
CO- 9.0.0.
2) IF the 'dot' REMAINS BLUE: Proceed to
PUMP ERRORS.

CO- 8.2.2 ABIC = BIC

a) If not already, allow the external flow indicator's 'bob' to begin moving up and down
b) Based on the external meter's reading versus TCD, TWO (2) possible scenarios:
1) IF (and ONLY if) LESS THAN TCD - (minus) 0.4: See procedure number
2) IF MORE THAN TCD + 0.4 i.e.: See procedure number
