a.
In all cases, the unit’s current operational
log file will be written to the USB device.
During this operation, the unit’s RUN
TIME indicator will flash.
b.
If the version of the Operational Software
(E_Image.s19) on the upgrade USB device
is newer than the unit’s installed
software, then it will be updated. The
unit’s RUN TIME, HUMIDITY and HIGH
PRESSURE indicators will illuminate solid
and the LOW PRESSURE indicator will
flash during this process. When
programming is complete, then the LOW
PRESSURE and COMPRESSOR indicators
will illuminate solid momentarily and
then all indicators will extinguish.
c.
The upgraded configuration (eeprom.eep)
will be written to the unit. There is no
indication of this process occurring
because it happens very quickly.
d.
Once all programming is complete, the
following indications will occur. If more
than one condition exists, then the
indicators will flash together.
The
LOW
PRESSURE
indicator
flashes
5
times
indicating
successful
RTC
clock
update.
The
HIGH
PRESSURE
indicator
flashes
5
times
to
indicate
successful
configuration
upgrade.
The
HUMIDITY
indicator
flashes
5
times
to
indicate
successful
firmware
update.

The unit will then restart normally
(indicators light top to bottom, then
extinguish bottom to top). The USB device
can now be removed.
8.1.4
To verify the upgrade process, plug the
upgrade USB device into a PC and open
the “UPDATE.LOG” file on the USB device.
The following is a sample of the file
contents:
Picture 8.1 – UPDATE.LOG File
a.
The log indicates success (OK), failure
(NOK) or not present/not processed
(N/A) for the two upgradeable items and
the RTC clock setting.
b.
The first log entry indicates the unit
model and serial number, and represents
the configuration of the unit before the
upgrade process.
c.
The second entry is an example of a
successful upgrade of the operational
software, a successful upgrade of the
EEPROM (unit configuration), and that
there was no SetClock.txt file to process.
The model number represents the
options and/or configuration upgrade,
and this number should match the
provided upgrade product label.
d.
The third entry is an example of a failed
EEPROM (unit configuration) upgrade.
The Operational Software will only be
upgraded if the version on the upgrade
USB device is newer than the unit’s
installed version.
8.1.5
Upon successful completion of the
upgrade process, place the provided
upgrade product label over the existing
product label on the dehydrator’s rear
panel.
