External Power Fault - External Voltage Too High
Alarm triggers when the supplied DC power is > 33 VDC. When this 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 **Remove DC Connection**
3442
External Power Fault - External Power Insufficient Current
Alarm triggers when the external power supply has insufficient current. When this
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 - DC Voltage Reversed
Alarm triggers when the voltage polarity is reversed when the device is attached
to an external DC source. When this occurs the device automatically switches to
operation using the internal battery. This condition is most likely caused by a
faulty DC source. The user should seek an alternate power source.
Mitigation/Info: DC Voltage Reversed, Internal Battery Operation,
Disconnect Power Source **Replace Power Source**
3450
Battery Discharge Fault - Battery Within 5 °C of High Limit
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 will
shut down to prevent failure. When this occurs the device will continue operation
using external power only. The device should be removed from the padded case
which acts as insulation. Shading the patient and ventilator from direct sunlight
may also help reduce the battery temperature.
Mitigation/Info: Battery Within 5 °C of High Limit, Remove Padded Case,
Continue External Power Operation, Shade Patient and Ventilator,
**Move To Cooler Location**
3451
Battery Discharge Fault - Battery Too Hot to Discharge
Alarm triggers when the battery temperature reaches
≥
75 °C (167 °F) and
external power is connected. Discharging the battery beyond this temperature
could destroy the battery and damage the device. During the alarm condition the
device will continue operation using external power. The device should be
removed from the padded case which acts as insulation. Shading the patient and
ventilator from direct sunlight may also help reduce the battery temperature.
Mitigation/Info: Battery Too Hot to Discharge, Do NOT Remove External
Power!, Remove Padded Case, Ensure Ability to Manually Ventilate
Patient, **Move To Cooler Location**
