2. Directions for Use
Step 8:
Press the
RUN/PAUSE
key. Pump will begin running.
Display will show programmed rate, the arcs around
the run symbol will rotate and display will read FEED
INTERVAL (
Figure 2-20
).
While pump is running the following may be viewed by
pressing the appropriate key: Rate, Dose, and Feed Interval.
To view the amount delivered in the current feeding,
press the
VOL/TOTAL
key (
Figure 2-21
). This counter
will reset itself when the previously programmed dose
has been completed and a new feeding is started, or
if a feeding is interrupted and Rate, Dose or Feed
Interval has been changed.
To view the amount delivered over the course of sev-
eral feedings press the
VOL/TOTAL
key a second time
(
Figure 2-22
). Display will read TOTL then the amount.
This counter never resets itself, it can only be reset by
the user.
While pump is running, the settings cannot be changed and the Prime fea-
ture is disabled.
If you want to stop pump at any time, press the
RUN/PAUSE
key. Display
will show rate, and pump will be in pause mode. Or, turn pump off by press-
ing the
ON/OFF
key.
When you would like to restart pump, press the
ON/OFF
and/or the
RUN/PAUSE
key. Pump will save the memory of where it was in the feeding
before stopping. Press the
RUN/PAUSE
key and pump will restart at the
point where it was stopped.
NOTE: Any changes to pump settings during a feeding cycle will cause pump
to start a new feeding; it will not start where it left off.

3. Alarms, Messages, and Indications
Indications
CHEK
(
Figure 3-10
)
Pump will sound a dual tone beep once and CHEK,
RATE, DOSE, and FEED INTERVAL will all blink on the
display.
Why:
This alarm sounds when the RATE, DOSE, and FEED
INTERVAL are not compatible. As discussed in the Interval Feeding Example
(Page 13)
, pump divides the dose by the rate to determine the amount of time
required for the dose to be delivered. Based on the RATE and DOSE combina-
tion, when the FEED INTERVAL is being programmed, the first value available
will be the first value that is compatible with the RATE and DOSE settings.
Should the RATE or DOSE be changed after the FEED INTERVAL has been pro-
grammed, and the combination requires the delivery time to be longer than the
amount of time programmed as the FEED INTERVAL, user will receive this alarm.
For example, if rate is 100 ml/hr, and dose is 200 ml, then the pump will
take 2 hours to deliver the dose. The first available
FEED INTERVAL will be 2.00 hr. However, if the dose is
changed to 300 ml, the dose will now take 3 hours to
deliver and therefore 2.00 hr is an impossible FEED
INTERVAL. If the
RUN/PAUSE
key is pressed before the
FEED INTERVAL has been changed (the next available
value being 3.00), the pump will give the CHEK alarm.
To correct the problem:
Press the
RUN/PAUSE
key to
put pump in pause mode, and reprogram the settings.
TO STOP LET GO
(
Figure 3-11
)
When pressing and holding the
PRIME
key, alarm will
sound once, pump will begin pumping at maximum rate
of 600 ml/hr and display will read "TO STOP LET GO".
To stop priming:
Release the
PRIME
key.
