P- H.3.0 Isolate 24 Volt Connections; P- H.3.1 System Initialization?; P- H.3.2 System Initialization Reaches 100%; P- H.3.3 Alarm Reoccurs - Fresenius Medical Care 2008K2 Troubleshooting Manual

P- H.3.0 ISOLATE 24 VOLT CONNECTIONS

TURN THE MACHINE OFF!
a)
b) Open the power supply enough to see
the top edge of the Power Control
Board (Figure right).
c) ENSURE the 24V Power Harness is
connected SECURELY, pin for pin, to

Yes System Initialization reaches 100%! See procedure number
No System Initialization does NOT reach 100%! Proceed to
P- 2.0.0.

P- H.3.2 SYSTEM INITIALIZATION REACHES 100%

NOTE: The previous Voltage Detection calibration may have solved the problem!
NOTE: If the 24V Power Harness was not securely connected this may have been the problem!
a) Place the machine into Dialysis OR Heat Disinfect OR Rinse.
b) Does a voltage OR "Failed Sending Data" OR "Temp Over 95 Degrees" alarm occur?
Yes Alarm occurs! See procedure number
No An alarm does not occur! Allow thirty (30) minutes or longer. If a voltage OR "Failed Sending
Data" OR "Temp Over 95 Degrees" alarm reoccurs see procedure
alarms DO NOT reoccur the troubleshooting Guide cannot locate an immediate problem.

P- H.3.3 ALARM REOCCURS

a) Turn the machine off then back on HOWEVER, when "System Initialization" reaches 100%
press any keys yet!
b) Per the OBSERVED symptom, FOUR (4) possible scenarios 1) or 2) or 3) below:
1) IF "5V High" OR "5V Low" OR "12V Power Fail": See procedure number
