CO- 10.0.30 PROBLEM WITH POST DIALYZER COND
ENSURING the shunt door is open, is screen 0's Post Dialyzer Cond more than 10.000 mS?
Yes Post Cond more than 10.000! See procedure number
No Post Cond less than 10.000! See procedure number
CO- 10.0.32 POST DIALYZER COND MORE THAN 10.000
Is screen 0's Post Dialyzer Cond more than 20.000 mS?
Yes Post Cond more than 20.000! See procedure number
No Post Cond less than 20.000! Proceed to
CO- 10.0.34 ISOLATE POST COND CIRCUIT
a) Figure right, from the distribution board, unplug the
th
10
connector cap from the LEFT. This is Post
Dialyzer Cond Cell #13, "x13, COND-POS"!
b) Using a flashlight, check inside the "x13" position
for damage or corrosion.
c) Call debug screen 5. Is FPOS more
than 4000 (four thousand)?
Yes FPOS more than 4000! Either Post Dialyzer Cond Cell #13 was not unplugged from
position "x13" or there is a problem with its circuit. THREE (3) possible bad
components': 1) Sensor Board

To prevent "Cond Offset Failure" place the machine into T and C mode. Refer to
OPERATING
No FPOS less than 4000! See parts a AND b below:
a) Per the Figure right, place the
TWO-RESISTOR SET
vacant distribution board position, "x13, COND-POS".
b) Is FPOS between 13500 and 14500?
Yes
