Figure 58: USB Port on HMI screen
NOTE:
In order to prevent viruses from being transferred
from the USB drive to the HMI, it is important that a
clean USB drive is used. Do NOT use a USB drive
that contains any auto-executable files.
If a directory screen opens when the USB drive is inserted,
close out of that screen and continue with the directions
instructed below.
To Download Trend History:
• Make sure that the “History File” text field on the right
side of the Alarm History Screen shows a date. If it shows
“ALARMS” rather than a date, press either the PREV
or NEXT button. (Pressing the PREV button when the
“History File” text field shows “ALARMS” will bring up
yesterday’s date. Pressing the NEXT button when the
“History File” text field shows “ALARMS” will bring up
today’s date.)
• Use the PREV or NEXT button to change the date in the
“History File” text field to the desired date. The dates will
stop scrolling when the last file in that direction has been
reached. (The HMI PC will store 30 days of history at a
minimum. More days might be stored depending on the
trend history file sizes. The HMI PC will automatically
delete old trend history files as needed to make room for
new trend history files.)
• Take note of the file size of that date’s history by viewing
the “Size” text field. Press the COPY to USB button and
watch the file size in the “Size” text field count up to the
noted file size. Once this text field has stopped counting
and has reached its actual file size, the download of that
file to the USB is complete.
• Repeat this process for each desired day of trend history.
Each day must be downloaded individually. It is not
possible to download multiple days of trend history at
once.
To Download Alarm History:
• Make sure that the “History File” text field on the right side
of the Alarm History Screen shows “ALARMS.” If it shows
a date instead, press the ALARMS button.
• Take note of the file size of the alarm history by viewing
the “Size” text field. Press the COPY to USB button and
watch the file size in the “Size” text field count up to the
noted file size. Once this text field has stopped counting
and has reached its actual file size, the download of the
alarm history to the USB is complete. (Note that unlike
the trend history files, alarm history only has one file.)
Viewing/Using Trend History and Alarm History Files:
• To download trends press the Trends button and then
“Copy Service Trends”. There will be a folder created
called “Trend_Files”. Trend history file names will be
displayed as “TrendXXXXXX”, where the first two X’s
will be numbers to indicate the year, the second two X’s
will be numbers to indicate the month, and the last two
X’s will be numbers to indicate the day. For example, if
there is a file called Trend140510, it indicates that the file
contains trend history from 5/10/2014.
• To download alarms, click “Copy”. The alarm history file
name will be displayed as “AlarmXXXXXXXX.”
• All trend history and alarm history files are saved from
the HMI PC as .csv files. These files can be opened on
a normal PC and manipulated using Microsoft Excel for
personal use.
If tech support is requested, the original
(un-manipulated) .csv files must be sent to Daikin
Applied. Any other file formats are NOT accepted.
Active Alarms Screen
The Active Alarms Screen (
) is only accessible when
an active alarm exists on the unit. Pressing the red ALARM
button on any screen will access the Active Alarms Screen. (In
this manual, the red ALARM button is displayed as an example
in
