Safety functions

The electronic components continuously monitor the proper function of the sys-
tem. System malfunctions are indicated with audible warning tones, error mes-
sages, and/or the blocking of system functions. A table listing a summary of
possible error and warning messages is provided in Chapter 9, Error and Warning
Messages.
If the intrauterine pressure exceeds the intrauterine pressure setting by
10 mmHg for longer than 5 seconds, the pressure reduction function is activated.
The roller wheel will move forward or backward a few times during the pressure
reduction process. If the pressure cannot be reduced, the message Overpressure/
Open Stopcock is displayed and three audible tones are emitted.
The message Maximum Pressure is displayed and the pump will emit 3 audible
tones once the intrauterine pressure exceeds 150 mmHg. The maximum permis-
sible pressure has now been reached.
If the intrauterine pressure exceeds 200 mmHg for longer than 5 seconds, the
roller wheel stops and the message Overpressure/Check Stopcock is displayed.
Three short continuous audible warning tones are continuously emitted until the
pressure is reduced. Once the intrauterine pressure falls below 200 mmHg, the
audible alarm stops and the pump wheel resumes turning automatically.
If the inflow tube set is not inserted properly over the roller wheel, pressing the
Prime button results in a short audible tone and Check Tube Set Installation is
displayed. The roller wheel does not start to turn.
If a malfunction is detected in the pressure measurement electronics, Sensor Er-
ror is displayed and five short audible tones are emitted. The roller wheel stops
turning.
If the maximum permissible weight of the scale is exceeded (65 lbs/30 kg), a con-
tinuous audible tone is emitted and Scale Overloaded Check Scale is displayed.
The warning stops once the excess weight is removed from the scale.
If a container is removed from the scale while the pump is being operated, three
short continuous warning tones are emitted and Container Change, Press Re-
sume is displayed. The audible warning tone stops once the initial status is re-
stored or the Pause/Resume button is pressed
If the last pre-set intrauterine pressure setting is greater than 80 mmHg, this val-
ue is reset to the default value of 80 mmHg.
Each additional deficit increase by 100 ml above the selected deficit threshold
triggers 3 audible warning tones that are repeated while the pump continues to
operate. The message Deficit Limit Exceeded is displayed.
When the deficit rate exceeds 300 ml/min, three audible warning tones are emit-
ted and the message High Fluid Loss Check Leakage is displayed. If no obvious
source of high fluid loss can be identified, an assessment of potential cervical or
uterine perforation should be made.
Five short audible tones are emitted and Motor Error is displayed. It is possible
that errors can occur in the start up sequence prior to the enabling of the Pump
Display. In this situation, the Pump Display will remain blank.
