each day of that month that the datalogging is running.
If a review of the History Report shows that an
abnormal event occurred 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
since the card is located inside the control
cabinet.
To start the Data Logging, insert the SD card into the
SD card slot on the 03478 IPUII board. The label on
the SD card should be facing outwards.
Once the SD card is inserted and the unit is powered
up, press the OPTIONS key. Then press the Down
Arrow key to advance to the DATA LOG TO FLASH-
CARD selection. 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 8 months worth
of data. A smaller card may be used that will hold less
data but should be tested for compatibility. The con-
troller operating system does not support SD cards
larger than 2GB. When the SD card becomes full, the
oldest date file is automatically deleted and a new day
log file is written in its place.
To stop the data logging and retrieve the SD card, press
the OPTION key and then the Down Arrow key to dis-
play the DATA LOG TO FLASHCARD option and
then use the Right Arrow key to select OFF then press
the ENTER key.
Again, follow the Quantech Safety Directives to stop
the chiller, power off the unit and open the control cab-
inet door to retrieve the SD card.Once inside the con-
trol cabinet, lightly press in on the SD card and then re-
lease the pressure. The SD card should pop out slightly
