Action/Troubleshooting
O2 PROP VALVE FAIL
Reboot System. If problem continues, Replace the Mixer.
O2 SENSOR FAILURE
Calibrate O
If calibration fails, replace O
If calibration continues to fail, wait 90 minutes and repeat calibration.
If calibration fails after 90 minute, replace VIB.

POWER ERROR
If the P2 indicator never lights or lights only briefly,
• proceed to interconnect fault isolation procedure (Section 7.10.12).
If the P2 indicator remains lit for more than 2 seconds,
• isolate the failed valve (outflow or scavenging) circuit with manual valve controls.
Replace and retest in the following order (Also see Section 7.10.):
• Valve
• ADB
OUTFLOW ZERO POINT
ERROR
Replace and retest in the following order (Also see Section 7.10.):
• Outflow Zero Valve
• Flowmeter Block
• ADB
OUTPUT FLOW LIMIT
REACHED
Indicates commanded agent flow could not be achieved because the vaporizer reached its maximum
flow capability. This occurs at high flow and agent settings, primarily with Sevoflurane. The user sees an
alarm message advising them to reduce flows and the agent monitor may show an under delivery.
