1. TMP is UNSTABLE if the 'actual' TMP bar rises ( ), greater than +40, toward the 520 Limit
OR exceeds the 520 Limit causing a "TMP Is High" alarm: See procedure number
(page 32).
2. TMP is UNSTABLE if the 'actual' TMP bar falls ( ), greater than -40, toward the lower 0
Limit OR falls below the 0 Limit causing a "TMP Is LOW" alarm: See procedure number
F- 6.6.0 (page 32).
3. TMP is STABLE: See procedure number
F- 6.6.0 TROUBLESHOOT FLOW ERROR (UNSTABLE TMP)
NOTE this procedure and page number. It may be necessary to perform all procedures below:
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, perform
DIAPHRAGM (page 238).
c) If a diaphragm leak is not located, return to Dialysis program. If the Flow Error reoccurs see procedure
number F- 1.0.2 (page 14).
F- 6.7.0 TROUBLESHOOT FLOW ERROR (STABLE TMP)
NOTE this procedure and page number. It may be necessary to perform all procedures below:
