Error messages and corrective action<br />
11.17 No internal communication<br />
The active control processor and the backup control processor cannot communicate<br />
with each other. Possible ca<strong>use</strong>s to be considered include the lack of power supply or a<br />
severe system error.<br />
<strong>Instructions</strong><br />
1. Check the status of the patient.<br />
2. Check the charge level indicator of the batteries. In the case of battery mode: Connect<br />
the <strong>Ikus</strong> to the mains power supply. Ensure that the power switch (mains power switch)<br />
is set to ON/EIN.<br />

11.18 Emergency operating mode<br />
11.18.1 Univentricular<br />
The pump is driven by the last intact pneumatic system.<br />
The pneumatic system continues operating with the set parameters. The parameters<br />
may now be adjusted. However, it is not possible to switch to biventricular mode.<br />
Warning!<br />
• No system is available any longer as a redundancy. In the event of the failure of the intact<br />
pneumatic system, there is a risk of stoppage of the <strong>Ikus</strong>.<br />
Always do the following immediately:<br />

11.18.2 Biventricular<br />
Both pumps are jointly driven by the last intact pneumatic system.<br />
The pneumatic system works with fixed parameters (synchronous mode, 250 mmHg<br />
systolic pressure, -100 mmHg diastolic pressure, 70 bpm, relative systolic duration<br />
40 %). These parameters cannot be changed.<br />
Possible ca<strong>use</strong>s:<br />
• Two of the three pneumatic systems are faulty.<br />
• The Driving Unit <strong>Ikus</strong> was run <strong>for</strong> too long in battery mode (message: “Emergency<br />
operating mode due to empty batteries - threat of total failure!”). The <strong>Ikus</strong> could no<br />
longer construct any reliable values. To rule out a fault in the control, the <strong>Ikus</strong> has<br />
switched to the backup system and the backup control processor. The message “Backup<br />
processor started” is displayed.<br />
Warning!<br />
• No system is available any longer as a redundancy. In the event of the failure of the intact<br />
pneumatic system, there is a risk of stoppage of the <strong>Ikus</strong>.<br />
