F- 2.9.2 ISOLATE TEMPERATURE AND CONDUCTIVITY
a) ENSURE NO HYDRAULIC LEAKS BEFORE CONTINUING!
b) Call the Home screen. Is [Temperature] REMAINING between 35.5 and 38.5 °C AND Conductivity
REMAINING between 13.0 and 14.5 mS? TWO (2) possible scenarios:
1) IF (and ONLY if) Temperature AND / OR Conductivity is NOT remaining in range: Proceed
to page 47, procedure number F- 2.0.15.
2) IF Temperature AND Conductivity in range: See parts a THROUGH f below:
a) At the bottom of the screen, press the ‘Dialysate’ tab.
b) If necessary, adjust the Conductivity Limits until the
‘Actual’ Conductivity is CENTERED between them
(Figure right).
c) Press ‘Enter’
d) Allow three (3) minutes OR until if the Conductivity
window remains white!
e) Call debug screen 0 (Figure right) and locate Valve #24’s
‘dot’. At this point it should be white.
f) See procedure number F- 2.9.4 (page 44).
F- 2.9.4 ISOLATE ‘OUT OF BYPASS’ CIRCUIT
a) CLOSE THE SHUNT DOOR COMPLETELY!
b) Figure right, from here forward, if (and ONLY if) a “Dial
Valve Failure” OR “Act Byp Valve Fail” banner appears
proceed to page 711, Section 26.
c) Is Valve #24’s ‘dot’ BLUE?
Yes BLUE! See procedure number F- 2.0.10 (page 45).
No WHITE! See parts a THROUGH d below:
a) ENSURING the shunt door is closed, call debug screen 2.
b) ENSURE CVRCLS (2
nd
column from left) = 1!
c) Return to debug screen 0.
d) Allow up to three (3) minutes OR until if Valve #24’s ‘dot’ turns blue. TWO (2) possible
scenarios next page:
