The Battery
Running on Battery Power
EnteraLite

will run for 24 hours at
a rate of 125 ml/hr. A fully depleted battery
takes approximately 6 hours to fully charge.
When pump is running on battery power the
battery symbol will appear in the display
(
Figure 2-24
).
The segments or blocks between E and F represent the fuel gauge of the bat-
tery. Each block represents approximately 6 hours of charge. When each bar is
half spent, it will begin to flash, indicating approximately 3 hours of charge is
left for that bar. When the last block is gone, the battery symbol will blink to
indicate there is approximately 1 hour of charge left. Display will flash LOW
BATT every 3 seconds and pump will beep every 2 seconds to remind user of
low battery condition. When battery is fully depleted pump will turn off auto-
matically.
NOTE: The battery life is an approximation based on a fully charged battery and
a flow rate of 125 ml/hr. Higher flow rates will run the battery down faster,
while lower flow rates and interval feedings will allow the battery to last
longer.

3. Alarms, Messages, and Indications
NO FOOD
(
Figure 3-6
)
Pump will sound a dual tone beep repeatedly and dis-
play will read NO FOOD.
Why:
This alarm has occurred because pump has
detected air in the tubing. It takes approximately 1 ml
of air, which is approximately 5 inches (12.7 cm) in
length entering the teal colored tubing to cause an
alarm.
To correct the problem:
Press the
RUN/PAUSE
key to
silence alarm and place pump in pause mode, then
check the following:
1. Check feeding bag for food. If it is empty, refill bag and prime the set.
2. Check tubing for air bubbles. If bag is full but air is present in the tubing,
disconnect set from patient, press and hold the
PRIME
key until air bubble
has moved to the end of the tubing.
3. Check cassette receptacle for cleanliness, especially around the air sensor.
If cleaning is necessary, refer to
CHAPTER 4 - CLEANING (Page 28)
.
4. Check that an EnteraLite
®

™
Disposable Set is loaded into pump prop-
erly and door is closed.
5. Check disposable set for worn tubing. If it is worn, replace with a new set.
NOTE: Blenderized or aggressively mixed solutions may have foam. Small
foam bubbles may collect in the air sensor area and must be cleared in order
to avoid a NO FOOD alarm. Allowing foamy solutions to sit for 10 to 15 min-
utes after mixing and prior to pouring into the bag will reduce the amount
of foam.
