Power up tests and checks
This section explains the sequence of the pumps internal
initialisation tests and checks carried out on a Cold boot which takes
place if the
On/Off
key is pressed, or the door is opened whilst the
pump is switched off.
The end of this section describes what happens during a Warm boot,
which takes place if the microprocessor is reset when the pump is
already switched on.
Cold boot
When the pump is turned on, the
cold boot
sequence is as follows:
The I/O ports of the microprocessors are initialised, placing all
system components in the start up configuration.
A write/read back test is performed on non-volatile RAM. If this
test fails, the following message is displayed and the software is
locked allowing no further processing:
If the pump is plugged into AC power, the message remains until
the pump is unplugged. If being powered by the battery, the
message is displayed for 5 seconds, then the pump automatically
turns off.
A checksum comparison is performed on non-volatile RAM, and, if
it fails, system warning 13 is recorded for viewing in Biomedical
Special Functions. A memory location is then checked to
determine if the initialization was from a cold-boot or warm boot.
All CPU RAM locations are cleared.
The main CPU computes a checksum of its ROM contents and
compares this against a predetermined value. If a ROM checksum
error occurs, the following message is displayed, and the software
is locked allowing no further processing:
If the pump is plugged into AC power, the message remains until
the pump is unplugged. If being powered by the battery, the
message is displayed for 5 seconds, then the pump automatically
turns off.
Timers, counters, registers, and interrupts are initialised for
operation.
Counters and timers are initialised for pump history information.
A jumper wire is detected, thus determining whether the pump is
micro/macro (Model 500/3000) or micro only (Micro 505/3100).
