Powering down
This section explains what happens when the pump is powered down
(switched off). It describes:
Manual power down, when the On/Off key is pressed
Automatic power down, which occurs when the pump has been left
on and alarming for 72 hours, or if the battery voltage becomes too
low.
Manual power down
The pump can only be turned off by pressing
On/Off
while the door is
closed. If the pump is running, you must first press
Hold
, then
On/
Off.
The master CPU stops pumping operations and all system
components are disabled. The non-volatile memory is updated with
checksums. At this point, if the pump is on AC power, it will continue
to keep track of AC on time for pump history. The green charge light
is lit, indicating that the battery is charging. If powered by battery, a
non-volatile memory location is initialised, indicating power down
has occurred, after which the pump turns off.
If the pump is operating on battery power, and if the pump is stuck in
a fault mode where the CPUs are not operating properly, a special
command (OFFCPU2) allows
On/Off
to operate.
If the pump is connected to AC power, turned off, and the cord is then
unplugged, the pump powers down completely after writing data to
pump history.
Automatic power down
If the pump is left on hold (following an alarm, or if left idle) for
approximately 2 minutes with the door closed, the
insistent
audio
alarm sounds. If the pump is left on hold with the door open, the
pump alarms after approximately 6 minutes. In either case, if left
alarming for 72 hours, the pump automatically shuts off.
If the battery status in the Message Display indicates:
the pump enters hold (if running), sounds the
insistent
audio alarm,
and the hold light flashes. If left alarming, the pump will
automatically turn off in 15 minutes, or when the battery reduces to
10 volts.
