Estimating Remaining Time for In-Use Batteries
When approximately 15 minutes of battery power are left, the System Controller initiates a
Low Battery Power
Advisory
alarm, which is indicated by the following:
• Flashing yellow diamond on the System Controller’s user interface
• The words
Low Battery
and
Replace Power
alternate on the user interface screen
• Alarm tone: slow beep
When approximately five minutes of operation remain, the System Controller initiates a
Low Battery Power
Hazard
alarm, which is indicated by the following:
• Flashing red battery on the System Controller’s user interface
• The words
Low Battery
and
Replace Power Immediately
alternate on the user interface screen
• Alarm tone: constant tone
The Low Battery Power Hazard Alarm requires an immediate response. Refer to
on page 7-3 for detailed instructions on responding to System Controller alarms.
During a Low Battery Power Hazard Alarm, the system reverts to power saver mode and gradually
ramps down to the Low Speed setting. If the Fixed Speed setting is lower than the Low Speed Limit,
the Pump remains at the lower speed setting.
The LVAS remains in power saver mode until a new pair of fully-charged batteries are installed, or
until the System Controller is connected to the Power Module, Mobile Power Unit, or until no
further power remains.
When adequate power is supplied, the Pump reverts to the previous mode and speed, and the
red battery alarm clears.
