•
FCC > 150% of the Li-Ion design capacity
•
Corrupted Gas Gauge
•
Cycle the Internal Li-Ion (discharge
battery so that capacity change is
> 50%, then rest for > 2 hours.
Charge to 100%, then rest for > 2
hours)
•
Replace Internal Li-Ion battery
E-269 •
Error indicates an open VBULK FET. This
MOSFET connects the output of the AC/DC
supply to the input of the boost converter. Unit
will not run on AC power. Will use battery power
if available
•
Replace Power Management PCA
E-270
•
Error indicates an open Q11, which controls the
discharge of the Li-Ion batteries post VbattLi.
When the Lithium Ion power is selected, this FET
is turned on. If Q11 fails open, there will be no Li-
Ion battery power to the system
•
Replace Power Management PCA
E-272 •
Charger chip failure
•
FET failure
•
Replace Power Management PCA
E-273
•
Unit not calibrated
•
Calibration table corrupted
•
Recalibrate the device
•
Replace the System/CPU PCA
E-274 •
Unit not calibrated
•
Calibration table corrupted
•
Recalibrate the device
•
Replace the System/CPU PCA
E-290
•
One or more “Ventilator Service Required” errors
are active in the system
•
Examine the Significant Event Log
error log. The first column of data
contains the first error code that is
causing this error message.
•
Address according to this first error
code
•
Each time you address an error,
cycle the motor (OFF to ON to
OFF) and check the Significant
Event Log again until this alarm is
no longer sounded
•
Remove all power from the unit
and then reapply power, then turn
the motor ON to see if this
message is still reported
E-302 •
Voltage reference on internal ADC failed
•
Replace System/CPU PCA
E-311 •
Unit wasn’t calibrated or calibration table was
destroyed
•
Recalibrate
•
Replace System/CPU PCA
