DESCRIPTION OF CONTROLS, INDICATORS, ALARMS & CONNECTIONS
3-22
OPRHT50NA B0908
exception of OCCLUSION & FAULT BAT SYS, all other Device
Alert alarms are non-recoverable and will result in the HT50
discontinuing ventilation. When this occurs, the ventilator must
be powered down by pressing the On/Standby button. DO NOT
use the ventilator until the cause of the alert has been
determined and corrected.
NOTE:
See Pg. 3-17, Occlusion Alarm, Device, and Pg. 3-21,
Fault Battery System Alarm, for a detailed description of these
recoverable Device Alert Alarms.
There are three possible messages that will be displayed when a
non-recoverable Device Alert Alarm occurs; (1) MOTOR FAULT (2)
10V SHUTDOWN and (3) SYSTEM ERROR. For MOTOR FAULT
and10V SHUTDOWN the full text message will be displayed for 5
seconds, followed by an abbreviated form of the message, eg.
MTR Fail, or 10V Fail. A timing message will also appear,
documenting how long the condition has been present. The
format for the time is “H:MM:SS.” The SYSTEM ERROR
message will always be displayed with full text.
NOTE:
If the cause of the SYSTEM ERROR does not allow the
HT50 to display the alarm message and the Device Alert indicator
to light, the ventilator will shut down and the Shut Down Alert
Alarm will activate. Upon the next power up of the unit, the
SYSTEM ERROR message will be displayed. If the cause of the
alarm has been corrected, the message can be cancelled by
pressing the Silence/Reset button.
WARNING
If a non-recoverable Device Alert alarm occurs,
immediately disconnect the patient from the ventilator and
provide an alternate method of ventilation.
NOTE:
A non-recoverable Device Alert Alarm cannot be silenced
without first turning the ventilator Off (Standby).
