Advisory Alarms
The Advisory alarms are listed in order of priority:
• Power Cable Disconnect: Indicates that one of the System Controller power cable connectors
(white or black) is broken or disconnected from power (the Power Module or two HeartMate
14 Volt Lithium-Ion batteries). Immediately connect the indicated power cable to a power
source.
• Low Voltage Advisory: Indicates that either less than 15 minutes of combined power remain
for the two HeartMate 14 Volt Lithium-Ion batteries (during battery-powered operation), or the
System Controller is receiving inadequate power from the Power Module. Immediately
connect the System Controller to a functioning power source.
• Replace System Controller: Indicates the need for clinician assistance and may be a sign of a
System Controller malfunction. Ultimately, the alarm may not be able to be resolved,
necessitating the replacement of the running System Controller with the backup
System Controller. Refer to
Replacing the Current System Controller
on page 2-46 if this is the
case. After successfully switching to the backup System Controller, return the malfunctioning
System Controller to Thoratec Corporation for diagnosis.
• Communication Fault: Indicates that either the data transfer between the LVAD and the System
Controller has been lost due to a problem with the internal communication system, or the
primary and back-up communication wires in the Driveline are not functioning. Use the System
Monitor to silence the alarm while awaiting resolution, if needed. Also, exchanging the
Modular Cable of the Driveline may resolve the problem. Refer to
on page 2-51. If exchanging the Modular Cable does not correct the alarm, contact
Thoratec Corporation to determine the best next steps. Refer to page iii
for Thoratec
Corporation contact information.
• Replace Backup Battery: Indicates that either the 11 Volt Lithium-Ion backup battery inside the
System Controller is compromised or unable to fully support Pump function. Promptly replace
the faulted battery. Refer to
• WARNING: Low Speed Advisory: Indicates that either the Fixed Speed has been set 200 rpm
or more below the Low Speed Limit, or the System Controller is unable to maintain the speed
at or above the Low Speed Limit.
• Backup Battery Not Installed: Indicates that the System Controller's 11 Volt Lithium-Ion backup
battery has not been installed, the connection between the backup battery and
System Controller is not being made, or the backup battery is damaged or malfunctioning.
Refer to
• LVAD Fault: The LVAD has determined that one or more operating parameters is out of range.
Contact Thoratec Corporation to determine best next steps. Use the System Monitor to silence
the alarm while awaiting resolution, if needed.
