TMP- 3.4.0 ACFS NOT BETWEEN 3.5 AND 6.0 / ISOLATE PDIA
From debug screen 10, based on PDIA (middle column). TWO (2) possible scenarios:
1) IF (and ONLY if) PDIA = less than 4.0: See procedure number
2) IF PDIA = more than 6.0: Proceed to
TMP- 3.5.0 PDIA LESS THAN 4.0 / ISOLATE TRANSDUCER #9
a) Figure right, unplug the Dialysate Pressure Transducer
#9 from distribution board position X9, "P-DIAL".
IMPORTANT!
b) To avoid unnecessary work, using
the screen's clock (upper right), allow up to five (5)
minutes (PDIA response is NOT instantaneous).
PDIA should increase to 9.0 or more?
Yes PDIA increased to 9.0 or more! See procedure number
No PDIA DOES NOT increase to 9.0 or more! See parts A through D below:
A) Turn the machine OFF.
B) Swap in the following components (COMPONENT LIST below), one at a time, with known
good, and in between perform parts C and D to see if the new component fixed this
problem.
