However, due to occlusion changes in Revision E software, the ventilator no longer stops
ventilating if detecting an occlusion or continuous HIP (High Inspiratory Pressure). Instead,
the ventilator employs Occlusion Cycling Mode. In this mode, Safety and Exhalation Valves
are cycled open and closed to check if the condition still exists.
The combination of the Safety Valve closing again with both the patient wye and exhalation
ports blocked and ventilation resuming causes an out-of-bounds delivered volume condition.
This results in a reset and the ventilator logs the 1101 error code to memory.
As a result, any 1101 error codes occurring in 740 Ventilators with Revision E or G software,
can be disregarded as long as the date and time of the 1101 entry match the time of the test.
Revision H and later software corrects the test anomaly from occurring. Any 1101 error code
entries in Revision H and later software must be investigated as any other error code.
6.4.2 Error code 06027
There are two causes of the 06027 error code in the 700 Series Ventilator System. Only one is
a failure. The 06027 error code indicates the Safety Valve Current is out of specification. An
anomaly may cause the Alert Log to incorrectly record a 06027 error code under certain
circumstances when the unit has been switched off.
An Actual 06027 Error Code Event:
During normal ventilation conditions, if an actual 06027 error code occurs, the following
events will occur:
1.
The ventilator will reset.
2.
The main alarm speaker will be actively alarming.
3.
The main alarm LED will be flashing.
4.
A ‘CONTACT SERVICE’ message will be displayed in the message display window.
5.
The Alert Log will also recored the 06027 error code at the time of occurrence along with
a 13006 error code. The 13006 error code indicates that a Soft Reset occurred while the
unit was in normal ventilation mode.
A Non-Event Related 06027 Error Code
:
Under certain conditions, the Alert Log will record an error code while the ventilator is
powered off. The error code will remain in memory and is available in the Alert Log.
Every three seconds, software checks the safety valve current. When the ventilator is powered
off, the current to the safety valve diminishes as the 24V supply shuts down. However, if
during the power off sequence the software is doing the safety valve current check, and if
the 5V supply is still sufficient, the unit will identify a low current condition and record the
error code.
Summary:
If a non-event 06027 error code is logged, this error will not be accompanied by a 13006 error
code. In this case, disregard the 06027 error code.
