Co- 2.0.7 ‘Actual' Conductivity Between The Alarm Limits; Co- 2.0.7.1 Both Hicond And Locond = 0 And The Conductivity Window Is Red - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 2.0.7 'ACTUAL' CONDUCTIVITY BETWEEN THE ALARM LIMITS
IMPORTANT!
a) Press 'CONFIRM'!
b) Figure right, with 'Actual' Conductivity REMAINING
BETWEEN the Limits, what color is the Conductivity
window now?
1)
IF (and ONLY if) WHITE: See procedure
number CO- 2.0.8
2) IF RED: Call debug screen 3 to see
HICOND AND LOCOND (lower right). TWO (2) possible scenarios:
Scenario #1:
Scenario #2: IF HICOND = 1 OR LOCOND = 1! THREE (3) possible bad
components: 1) Actuator-Test Board; 2) Functional Board; 3) Motherboard.

CO- 2.0.7.1 BOTH HICOND AND LOCOND = 0 AND THE CONDUCTIVITY WINDOW IS RED

Allowing up to three (3) minutes, does the [Conductivity] window eventually turn white?
Yes [Conductivity] window white! See procedure number
No After three (3) minutes the [Conductivity] window STAYS RED! Perform parts a THROUGH d
below:
a) If a previous procedure placed the 274Ω resistor plug into the Conductivity Cell's
distribution board position remove it and return Conductivity Cell #7's connector to
distribution board position "X7, COND".
b) Close the shunt door and return the concentrate connectors to their rinse ports.
IMPORTANT! Place the machine into RINSE!
c)
d) Is the external flow indicator's 'bob' rising at least ¼ way up in the sight tube?
Yes
No Bob NOT moving! See parts a THROUGH c below:
page 340
( ).
IF (and ONLY if) BOTH HICOND AND LOCOND = 0! Select
the 'Dialysate' tab then see procedure number
(page 339).
'Bob' moving! See procedure number
a) Plug into acid and bicarb jugs.
b) Return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM')!
