Data logging
A 2GB SD card (p/n 031-03466-000) may be inserted
into the 03478 IPUII SD card slot to record the chiller
operating parameters at 5 s intervals. The data is stored
in a folder named RMYYYYMM where YYYY is the
year and MM is the month the data was recorded. The
controller creates a file for each day within this folder
with the format YYYYMMDD.csv where DD equals
the day of the month in addition to the YY to the year
and MM to the month fields. For example: The folder
named RM201503 is a folder created in March of 2015.
Within this folder would be a file for each day of that
month that the datalogging is running. If a review of
the History Report shows that an abnormal event oc-
curred on March 3rd at 2:05pm, the user can import
the 20150303.csv file into Excel and look at the system
parameter details leading up to the 2:05pm event.
Follow all Quantech Safety Directives
when inserting or removing the SD card
or USB drive since the device is located
inside the control cabinet.
To start the Data Logging, insert the SD card into the
SD card slot on the 03478 board. The label on the SD
card must be facing outwards. If using the USB drive
insert it into the USB Port on the IPU3 board
Once the SD card or USB drive is inserted and the unit
is powered up, press the OPTIONS key. Then press the
Down Arrow key to advance to the DATA LOG. Next
press the Right Arrow key to select ON then press the
ENTER key to start the Data Log. A 2GB SD card will
hold about one month's worth of data. A smaller card
may be used that will hold less data but must be tested
