F- 6.1.8 VERIFY FLOW RATE (BC SWITCH)

Do NOT reset alarms!
a)
b) Call debug screen 6. WITHOUT LOOKING AWAY, watch BC Switch (middle
column) for two (2) minutes OR until it EVER = 897 or more. FOUR (4) possible
scenarios 1) or 2) or 3) or 4) below:
1) IF (and ONLY if) BC Switch REMAINS ALWAYS = 897: ENSURING a "No Water" alarm has
NEVER occurred proceed to
2) IF (and ONLY if) BC Switch 'cycles' to more than four-hundred (400) for two (2) seconds
then to less than 3.0 for nine (9) seconds: Proceed to
3) IF (and ONLY if) BC Switch 'cycles' to more than four-hundred (400) but NEVER to 897:
See procedure number
4) IF BC Switch is NEVER more than four-hundred (400): See parts a THROUGH c below::
a) Call debug screen 1. If NPHT (upper right) is decreasing press and hold
the "1" key until it is more than 600 then see part b If (and ONLY if)
NPHT = 720 skip to part c.
Allow forty-five (45) seconds BEFORE continuing to part c!
b)
c) Return to debug screen 6 and continue to watch BC Switch for two (2) minutes. It may change
slightly but should REMAIN ALWAYS between 203 and 248?
Yes
No

F- 6.1.9 DETERMINE FLOW ERROR

From the Home screen, is [Conductivity] more than 14.8 mS?
Yes [Conductivity] = More than 14.8 mS! Proceed to
No [Conductivity] is less than 14.8 mS! Proceed to
page 89
F- 6.1.9 (page 57).
BC Switch is REMAINING between 203 and 248! The Flow Error is not
presenting at this time. It may be extremely intermittent! Return to
procedure number F- 3.8.0
BC Switch is NOT remaining between 203 and 248! Call the Home screen. TWO
(2) possible scenarios below:
1) IF (and ONLY if) [Dialysate Flow] has remained at 800 ml/min: See
procedure number
2) IF [Dialysate Flow] has NOT remained 800 ml/min: Set it to 800, allow thirty
(30) seconds, then return to (ABOVE) procedure number
