SC 7000 and SC 9000XL Patient Monitors
Troubleshooting and Remedial Action
1. Try replacing pod / monitor cable.
2. If problem persists, replace pod.
3. If problem persists, replace Main Processor PCB
Subassembly.
4. If problem persists, contact TSS in Solna or Danvers.
1. Unplug all patient parameter inputs to the monitor.
2. Set Patient simulator for an IBP static pressure = 0
mmHg, and plug simulator into Pod.
3. Plug Pod output cable into monitor.
4. Check that "Zero Required" appears in the message
field and that the IBP parameter box appears on the
display.
5. If either message or parameter box fails to appear,
replace Pod and cable with known-good Pod and
cable.
6. If problem persists, replace Main Processor PCB
Subassembly. Otherwise, continue.
7. Select IBP parameter field on MAIN screen, and
assure that Cal Factor is set to 100.
8. Select Zero in menu, and press in on rotary knob.
9. • If "Zero Accepted" appears in message field,
continue.
• If "--- Did Not Zero" appears in message field, do
either a or b as appropriate.
a If HemoMed Pod, try replacing Pod. If problem
persists, continue to c.
b If Hemo 2/4 Pod continue to c.
c Replace Main Processor PCB Subassembly, if not
already replaced in step 6. If Main Processor PCB
Subassembly already replaced, return monitor to
Siemens for repair.
10. Increase simulator pressure to 100 mmHg.
11. • If monitor reading = 100 ±1mmHg, return monitor to
clinical service.
• If monitor reading ≠ 100 ±1mmHg, replace Main
Processor PCB Subassembly, if not already
replaced in step 6 or step 9. If Main Processor PCB
Subassembly already replaced, contact TSS in
Solna or Danvers.
