CO- 10.2.0 CHECK SENSOR WIRING
a) Referring to Figure 309
sensor #13, AND Temperature sensor #44 to ASSURE they are plugged into the distribution board
correctly.
b) Check the entire length of each sensor's wiring harness for insulation damage or extreme 'stickiness'
(due to heat). Replace the sensor if damage is located!
c) Proceed accordingly (as noted in procedure number
Problem was noted with the Post Dialyzer COND sensor
number CO- 6.0.0
Problem was noted with the Post Dialyzer TEMP sensor:
TEMPERATURE SENSOR calibration per procedure. Does the "Operator Error" message occur?
Yes CAREFULLY repeat the calibration and ASSURE the correct resistors are placed at
distribution board position x44 as instructed! If the "Operator Error" message reoccurs,
four possibilities: 1) Bad sensor cable; 2) Bad sensor board; 3) Bad function board;
4) Bad distribution board.
No Return temperature sensor #44 to the distribution boa
and allow eight minutes. Assure flow through the external flow indicator. From debug
screen 0, if the Post Dialyzer data box is NOT greater than 34° C replace NTC #44 (see
page 154).
(page 154), CAREFULLY trace the wiring cables from post dialyzer Conductivity
