Tmp- 3.6.0 Pdia More Than 6.0/Isolate Transducer #9/Possible Open - Fresenius Medical Care 2008K2 Troubleshooting Manual

TMP- 3.6.0 PDIA MORE THAN 6.0 / ISOLATE TRANSDUCER #9 / POSSIBLE OPEN
1
a) A known good pressure sensor, from your spare parts, is required to isolate the dialysate pressure
circuit from the sensor circuit.
3
To ENSURE the sensor is known good, when it is plugged into distribution board position X9,
"PDIAL", on ANOTHER machine that is not exhibiting TMP problems, it will drive the machine's
debug screen 10 PDIA to between 3.5 and 6.0.
b) Figure right, plug the known good pressure sensor
into the malfunctioning machine's distribution board
position X9, "PDIAL". There is NO NEED to install the
pressure sensor into the hydraulic yet.
c) From the malfunctioning machine's debug screen 10, is
PDIA (middle column) between 3.5 and 6.0?
Yes PDIA between 3.5 and 6.0! The malfunctioning machine's Dialysate Pressure Transducer
#9 is bad.
No PDIA IS NOT between 3.5 and 6.0! See parts A through D below:
A)
Turn the machine OFF.
B)
Swap in the following components (see COMPONENT LIST below), one at a time, with
known good, and in between continue to parts C and D to see if the new component fixed
the problem.
COMPONENT LIST: 1) Actuator-Test Board
4) Functional Board

C)
With the known good pressure sensor remaining plugged in, return to Dialysis Program.
D)
If screen 10's PDIA is still NOT between 3.5 and 6.0 return to part A.
