Yes Dialysate pressure transducer #9 is bad (see
No See procedure number
TMP- 2.6.0 ISOLATE PRESSURE TRANSDUCER #9 / POSSIBLE OPEN
a) Referring to Figure 70
into Dialysate Pressure Transducer's distribution board position x9, labeled "P-DIAL".
b) From screen 4, does PDIA = less than 1?
Yes The dialysate pressure transducer #9 is bad (see
No See procedure number
TMP- 3.0.0 ISOLATE THE TEST BOARD
NOTE: With some machines the Actuator and the Test board may be combined (see
this event ONLY proceed to
a) Turn the machine off and swap in a known good test board (see
b) Return to Dialysis program and debug screen 4. With the red dialyzer quick connector out of the shunt,
Dialysate flow off, and the shunt door open, is PDIA between 4.0 and 6.0 volts?
Yes Problem solved! The previous test board is bad.
No The previous test board is okay. See procedure number
TMP- 3.0.1 ISOLATE THE ACTUATOR BOARD
a) Turn the machine off and swap in a known good actuator board (see
b) Return to Dialysis program and debug screen 4. With the red dialyzer quick connector out of the shunt,
Dialysate flow off, and the shunt door open, is PDIA between 4.0 and 6.0 volts?
Yes Problem solved! The previous actuator board is bad.
No The previous actuator board is okay. See procedure number
TMP- 3.0.2 TROUBLESHOOT TMP CIRCUIT
Five possibilities (refer to
c
board ; 4) Bad distribution board; 5) Bad motherboard.
a
Swap in a known good sensor board. Enter Service Mode
(Test and Calibration) to "Yes". Press the 'CONFIRM' key (the "x" turns blue). With the red dialyzer quick
connector out of the shunt, Dialysate flow off, and the door open, if PDIA is between 4.0 and 6.0 volts the
previous sensor board is bad.
b
The cable can be checked for continuity. NOTE that four (4) DIALYSATE TRANSDUCER connections
will be checked and proceed to page 228,
c
Swap in a known good function board. Place the new function board into T and C. With the red dialyzer
quick connector out of the shunt, Dialysate flow off, and the door open, if PDIA is between 4.0 and 6.0
volts the previous function board is bad.
TMP- 5.0.0 PERFORM PRESSURE TESTS
a) Remove the tubing from the P
b) Turn Dialysate flow ON (Dialysate Flow on/off LED off) and allow Conductivity and Temperature to
stabilize.
c) RESET all blood alarms and select the screen's Test & Options button. If the 'Pressure Test' button is:
TMP- 3.0.0
(page 185), plug one of the resistor plugs, from the four-resistor Temperature set,
TMP- 3.0.0
TMP- 3.0.1 (page 186).
