Co- 10.0.41 Prepare To Analyze Pre And Post Conductivity Stability; Co- 10.0.42 Isolate Flow Pump Digital Control (Flwp); Co- 10.0.43 Pre Conductivity Stability - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 10.0.41 PREPARE TO ANALYZE PRE AND POST CONDUCTIVITY STABILITY

a) Install a 'dummy chamber' in the Level Detector module and RESET ALL alarms!
b) Watch the screen for thirty (30) seconds. If a "Filling Program" banner occurs, allow thirty (30) seconds
before continuing!
NOTE: Multiple "Filling Programs" occurrences indicate an air leak that
repaired or else OLC tests cancel!!
c) If screen says "Standby For Test" OR the screen says "Test:..." allow the tests to finish THEN allow
three (3) minutes BEFORE continuing to procedure number

CO- 10.0.42 ISOLATE FLOW PUMP DIGITAL CONTROL (FLWP)

a) Call debug screen 1.
b) Press the "1" key for five (5) seconds.
c) Allow forty five (45) seconds BEFORE continuing to part d.
d) Call debug screen 0. Without resetting alarms, ENSURING Flow Error
REMAINS = 0 ALSO watch FLWP for two (2) minutes. TWO (2)
possible scenarios:
1) IF (and ONLY if) FLWP continually changes more than +/- 2 (two):
page 44
Proceed to
2) IF FLWP does NOT change more than +/- 2 (two): Reset ALL alarms
THEN see procedure number

CO- 10.0.43 PRE CONDUCTIVITY STABILITY

a) Call debug screen 5. Pre Dev val (right column) is the conductivity difference between
now and one (1) minute ago from Pre-Conductivity Cell #7. If no alarms it changes
continually!
b) After no more than two (2) minutes, if not already, Pre Dev val should fall to less than 135. TWO (2)
possible scenarios:
1) IF (and ONLY if) Pre Dev val is OR falls to less than 135: See procedure number
CO- 10.0.44 (page 387).
2) IF Pre Dev val NEVER falls below 135: Pre Cond is unstable! ENSURING no alarms occurred
see parts a AND b below:
a) Per the Figure (next page), using a flashlight and WITHOUT LOOKING AWAY, for one (1)
minute, if air bubbles are flowing through Pre Dialyzer Cond Cell #7's tubing locate and repair
the air leak!
b) If (and ONLY if) absolutely sure of no air, proceed to
CO- 10.0.60.
