Call debug screen 5. WITHOUT LOOKING AWAY, watch
TPRE
(top, middle column) for one (1) minute
noting its highest and lowest values. TWO (2) possible scenarios 1) or 2) below:
1)
IF (and ONLY if) TPRE changes more than +/- twenty (20)! TPRE is unstable:
Leaving the 6.04
KΩ plug installed, swap in the listed components (see COMPONENT LIST below), one at a time, with
known good, then return to Dialysis Program and repeat procedure number
(page 240) to
test each new component until
TPRE
does not change more than +/- 20.
COMPONENT LIST
:
1)
Power Logic Board
a
;
2)
Sensor Board
a,b
;
3)
Deaeration motor;
4)
Flow
motor.
a
To LOCATE these boards refer to
(page 9).
b
To prevent “Cond Offset Failure”
place
the machine into
T and C Mode
(refer to
OPERATING MODES
(page
Error! Bookmark not
defined.
))
2) IF TPRE does NOT change more than +/- 20 (twenty)! TPRE is stable!
Perform parts a THROUGH g
below:
a)
Turn the HEATER Switch ON!
b) To avoid error, read parts c THROUGH h below BEFORE performing them
c) Turn the machine off and replace NTC #3* with a known good . *To LOCATE NTC #3 refer to
(page 218).
d) Figure right, ENSURE the new NTC #3 is plugged
into the
2
nd
distribution board position from the left,
“MON-NTC”!
e) Turn the machine on and return to Dialysis Program
(
“Select Program” → ‘Dialysis’ → ‘CONFIRM’)!
f) From the Home screen, set [Dialysate Flow] to 500
ml/min and press ‘CONFIRM’.
g) WITHOUT LOOKING AWAY, watch the [
Temperature]
window for up to ten (10) minutes. Does it
EVER exceed 39.0° C even if only once?
Yes
Exceeds 39.0° C! See procedure number
(page 241). The old NTC #3 is
probably okay!
No
NEVER exceeds 39.0° C! The original problem (High Temperature) is no longer occurring!
See (ABOVE) procedure number
(page 222).
