CO- 3.0.0 CONDUCTIVITY IS GOOD / VERIFY DISPLAY
a) If removed from a previous procedure, return
Conductivity Cell #7’s connector to distribution board
position “X7, COND” (Figure right).
b) Call the Home screen.
c) Based on the machine’s [Conductivity] window
now, THREE (3) possible scenarios 1) or 2) or 3)
below:
1) IF (and ONLY if) = 17.0 mS: See procedure number CO- 3.1.0 (page 373).
2) IF (and ONLY if) = 10.0 mS: See procedure number CO- 3.2.0 (page 373).
3) ALL OTHER scenarios: Is the [Conductivity] window within 0.4 mS of TCD?
Yes [Conductivity] is within 0.4 of TCD! Proceed to
page 374, procedure number
CO- 3.4.0.
No [Conductivity] is NOT within 0.4 of TCD! Proceed to
page 383, procedure number
CO- 6.0.0.
CO- 3.1.0 [CONDUCTIVITY] WINDOW = 17.0 mS
a) Return the concentrate connectors to their rinse ports!
b)
IMPORTANT! Place the machine into RINSE!
c) ENSURING a Flow Error NEVER occurs allow ten (10) FULL minutes BEFORE continuing to part d!
d) Call debug screen 5. If debug does not appear press ‘Esc’
then call debug screen 5.
e) Is FPRE within four-hundred (400) of Pre Offset?
Yes FPRE within 400 of Pre Offset! See procedure number CO- 6.0.0 (page 383).
No FPRE is NOT within 400 of Pre Offset! Pre Dialyzer Conductivity Cell #7* is bad
* To LOCATE cell #7 refer to Figure 57 (page 374).
CO- 3.2.0 [CONDUCTIVITY] WINDOW = 10.0 mS
Call debug screen 5. Is FPRE within +/- 10 of Pre Offset?
Yes FPRE within +/- 10 of Pre Offset +/- 10! Either Conductivity Cell #7* was not plugged into
distribution board position “X7-COND” properly OR is bad. *To LOCATE Cell #7 refer to
Figure 57 (page 374).
No FPRE is NOT within +/- 10 of Pre Offset! Proceed to
page 383, procedure number CO- 6.0.0.
