T- 1.3.13 Temp Less Than 0.3 - Fresenius Medical Care 2008K2 Troubleshooting Manual

Yes TEMP LESS THAN 0.3! See procedure number
No TEMP is NOT less than 0.3! See parts a and b below:
a) ENSURE NTC 3's connector is unplugged from the
left, "MON-NTC". If NOT, return to (ABOVE) procedure number
b) Leaving NTC #3 unplugged, with the machine off, swap in the listed components (see
COMPONENT LIST below), one at a time, with known good, in between returning to
Dialysis Program, to test each component until screen 4's TEMP is less than 0.3.

T- 1.3.13 TEMP LESS THAN 0.3

a) Figure right, place the
resistor plug, from the TWO-RESISTOR
nd
2
SET, into the distribution board
position from the left, "MON-NTC".
b) From debug screen 4, is
TEMP 6.0 or lower?
Yes TEMP 6.0 or lower! See procedure number
No TEMP more than 6.0! See parts a and b below:
a) ENSURE the
nd
2
position from the left, "MON-NTC". If TEMP is still more than 6.0 see part b.
b) Leaving the resistor plug in place, with the machine off, swap in the listed components (see
COMPONENT LIST below), one at a time, with known good, in between returning to Dialysis
Program each UNTIL screen 4's TEMP is 6.0 or lower indicating the last component swapped
in is the problem.
