Low Battery
This triggers when external power is connected to a device that has an internal
battery that has drained to a low battery status. The device is warning you that in
the event of an external power failure the device has < 30 minutes of backup.
This alarm resolves when the internal battery charge has > 30 minutes of
operation. You must maintain monitoring of the device and the patient constantly
during this period.
Mitigation/Info: < 30 Minutes Operation, Operating With External Power,
Continue Charging With External Power, Ensure ability to manually aspirate
patient **Contact Service Center**
3441
External Power Fault
Alarm triggers when the supplied DC power is > 33 VDC. When this fault occurs,
the device automatically switches to operation using the internal battery. If the
supplied voltage drops to < 30 VDC the device automatically returns to operation
using external power. If the external power source is known to be good then the
AC/DC Power Supply may be faulty and need replacement. Contact the service
center for additional information.
Mitigation/Info: External Voltage Too High, Internal Battery Operation, Check/
Replace Power Supply, **Contact Service Center**
3442
External Power Fault
Alarm triggers when the external power supply has insufficient current. When this
fault occurs, the device automatically switches to operation using the internal
battery. If the external power source is known to be good then the AC/DC Power
Supply may be faulty and need replacement. Contact the service center for
additional information.
Mitigation/Info: External Power Insufficient Current, Internal Battery Operation,
Check/Replace Power Supply, **Remove DC Connection**
3444
External Power Fault
Alarm triggers when the voltage polarity is reversed when the device is attached
to an external DC source. When this fault occurs, the device automatically
switches to operation using the internal battery. This condition is most likely
caused by a faulty DC source. You should seek an alternate power source.
Mitigation/Info: DC Voltage Reversed, Internal Battery Operation, Disconnect
Power Source **Replace Power Source**
3450
Battery Discharge Fault
Alarm triggers when the battery temperature reaches 70 °C (158 °F) which is
5 °C (41°F) from its maximum operating temperature and external power is
connected. When the battery temperature reaches 75 °C (167 °F) the battery
shuts down to prevent failure. When this fault occurs, the device will continue
operation using external power only. Shading the patient and aspirator from
direct sunlight may also help reduce the battery temperature.
Mitigation/Info: Battery Within 5 °C
(41°F)
of High Limit, DO NOT remove
External Power!, Ensure ability to manually aspirate patient, Shade Patient and
Aspirator, **Move To Cooler Location**
