b) Return Post Dialyzer Cond Cell #13 connector to position “x13, COND-POS”.
c) From debug screen 0, ENSURE Post Dialyzer Temp reads more than 35° C AND Post Dialyzer
Cond MUST more than 10.000.
d) See procedure number CO- 10.0.66 (page 430).
CO- 10.0.66 ISOLATE PRE SENSORS STABILITY
a) Figure right, remove Pre Dialyzer Temp Sensor (NTC #3’s)
connector from the
2
nd
distribution board position from the
left, “MON-NTC”.
b) Using a flashlight, check the “x3” position for corrosion and /
or damaged pins. If damage is located this may be the
problem!
c) Avoiding vacant position #4, place the
6.04 KΩ plug, from the TWO-RESISTOR SET, into the
Pre Dialyzer Temp Sensor’s NTC #3 distribution board position “x3, MON-NTC”.
d) Remove Pre Dialyzer Cond Cell #7’s connector from distribution board position “x7, COND”.
e) Check the “x7” position for corrosion and / or damaged pins.
f) Leaving the 6.04 KΩ plug installed, place the
274 Ω plug, from the TWO-RESISTOR SET, into
Pre Dialyzer Cond Cell #7’s distribution board position, “x7, COND”.
g) From debug screen 5, TWO (2) checks then proceed according to the TWO (2) possible scenarios
after check #2.
CHECK #1 (TPRE): WITHOUT LOOKING AWAY, watch TPRE for one minute
noting its highest and lowest values. Subtract the lowest value seen from the highest.
Two (2) or less = GOOD! More than two (2) = BAD.
CHECK #2 (CPRE):
Watch CPRE (4
th
column from right, second box down) for
exactly one minute noting its highest and lowest values Subtract the lowest value
seen from the highest. Eight (8) or less = GOOD! More than eight (8) = BAD.
1)
IF (AND ONLY IF) TPRE AND / OR CPRE are ‘BAD’: Proceed to page 432,
procedure number CO- 11.0.00.
2)
IF TPRE AND CPRE are ‘GOOD’: See parts a through c below.
a) Return Pre Dialyzer Temp Sensor NTC #3s connector to position “x3, MON-NTC”. From debug
screen 0, ENSURE Pre Dialyzer Temp reads more than 35° C.
b) Return Pre Dialyzer Cond Cell #7 connector to position “x7, COND”. From debug screen 0,
ENSURE Pre Dialyzer Cond reads more than 10.0.
c) See procedure number CO- 10.0.705 (page 431).
