T- 1.0.155 Isolate Temperature Monitor; T- 1.0.16 Temp Stable Between 4.0 And 6.0/Verify Temperature - Fresenius Medical Care 2008K2 Troubleshooting Manual

T- 1.0.155 ISOLATE TEMPERATURE MONITOR

a) Figure right, plug the
TWO-RESISTOR
plug, from the
nd
SET 2
into distribution board position
from the left, "MON-NTC"!
b) Call debug screen 4.
c) Watching TEMP (lower left) for one (1) minute, THREE (3) possible scenarios 1) or 2) or 3) below:
1) IF (and ONLY if) between 4.0 and 6.0 AND STABLE i.e. does NOT change more than 0.2: See
procedure number
2) IF (and ONLY if) less than 4.0 OR more than 6.0: Perform parts a AND b below:
a) Remove the plug then reinsert it into the
still less than 4.0 OR more than 6.0 see part b. If now between 4.0 and 6.0 AND STABLE
(not changing more than 0.2 per minute) see procedure number
b) Use the
less than 4.0 OR more than 6.0 proceed to
between 4.0 and 6.0 AND STABLE (not changing more than 0.2 per minute) see procedure
number
IF between 1.0 AND 8.0 BUT changes more than 0.2 per minute:
3)
through C below:
A) Leaving the plug in place, turn the machine OFF.
B) FOUR (4) possible bad components, see COMPONENT LIST below. Swap in each, one at a
time, and in between continue to part C) to test the new component! COMPONENT LIST:
1) Sensor Board
* For each board, to prevent "Cond Offset Failure", place the machine into T and C Mode
(refer to
C) Return to Dialysis Program. Watch debug screen 4's TEMP for one (1) minute. If now between
4.0 and 6.0 and stable the last component swapped in is bad. If still not between 4.0 and 6.0 or
unstable return to part A to try the next component in the list!
T- 1.0.16 TEMP STABLE BETWEEN 4.0 AND 6.0 / VERIFY TEMPERATURE
Call the Home screen. Based on the [Temperature] window, TWO (2) possible scenarios:
1) IF (and ONLY if) between 35.1 and 38.9 °C: ENSURING the [Temperature] window is pale
yellow/white, see procedure number
2) IF less than 35.1 OR more than 38.9 °C: Proceed to
6.04 KΩ
resistor

6.04 KΩ
plug from a different TWO-RESISTOR SET. If (and ONLY if) TEMP is still
