How To Change The Controller - HeartWare Ventricular Assist System Patient Manual

Other Controller Components: Driveline Cover
The driveline cover should always cover the silver driveline connector (Figure 5) unless an
emergency controller exchange is required. With proper driveline cover position you should NOT
see the silver driveline connector.
6.2.2 How to Change the Controller
1. Sit or lie down.
2. Place the new controller within easy reach.
3. Connect back‐up power sources to the new controller.
 Confirm that the power cables are properly locked on the controller by gently pulling on
the cable near the connector.
 A "Power Disconnect" alarm will activate if a second power source is not connected to
the new controller within 20 seconds of controller power up.
 A "VAD Stopped" alarm will activate if the pump driveline is not connected to the new
controller within 10 seconds. This alarm will resolve once the pump driveline is
connected.

The SCROLL BUTTON on the right side of the controller is
used to see all active alarms as well as pump information
(RPM, L/min, Watts) on the Controller Display. The Scroll
Button will also clear resolved medium alarms from the
Controller Display and will brighten the Controller Display.
Simultaneously pressing and holding the ALARM MUTE
Button and the SCROLL button for 5 seconds will prevent
the "No Power" alarm from sounding when power is
removed during a controller exchange (see Section 6 .2.2,
"How to Change the Controller"). Use only on a controller
not connected to a pump.
