F- 9.0.5 ANALYZE TMP
a) Return CFS #10 to distribution board position x10, "CFS". If returned properly ACFS = between 3.0 and
8.1 volts.
b) Call the Home screen. Referring to
horizontal bars; yellow upper and lower alarm Limits (positioned at 520 and 0) and an 'actual' TMP bar
which is either red (with a TMP alarm) or green (no TMP alarm).
c) Press and release the 'RESET' key and then press and hold it for three seconds. If the "Adjusting TMP"
message is present allow it to expire. If a TMP alarm occurs repeat the RESET sequence up to twice
more then continue.
d) Watch the (green or red) 'actual' TMP bar. TMP is STABLE if (and ONLY if) it REMAINS between the 0
and 520 Limits AND varies less than +/- 40 mmHg in two minutes. Proceed accordingly (three scenarios):
1) TMP is UNSTABLE if the 'actual' TMP bar rises ( ), greater than +40, towards the 520 Limit OR
exceeds the 520 limit causing a "TMP Is High" alarm: See procedure number
2) TMP is UNSTABLE if the 'actual' TMP bar falls ( ), greater than -40, towards the 0 Limit OR
falls below the 0 limit causing a "TMP Is LOW" alarm: See procedure number
3) TMP is STABLE: See procedure number
F- 9.0.6 UNSTABLE TMP
NOTE this procedure and page number in case you need to return here:
NOTE
a) nine leak tests will be performed: 1) IOS; 2) Balancing Chamber Valves #31 through #38.
See SECTION 18A – AUTOMATED VALVE LEAK TESTS
b) If a leak is not located, see procedure number
F- 9.0.7 STABLE TMP
NOTE this procedure and page number in case you need to return here:
a) Perform SECTION 19 - TESTING FOR A LEAKING BALANCING CHAMBER DIAPHRAGM
b) If a diaphragm leak is not located, place the machine into Dialysis program. If BC Switch (screen 6) =
897 (constant) AND ACFS (screen 10) remains between 3 and 8 two possibilities: 1) Bad CFS
