SECTION 3 COMPONENT DESCRIPTIONS
TOUCHSCREEN DATA ACQUISITION
The APPT features data collection which is activated by
default on start up of the APPT, unless the user manually
deactivates or does not have a storage device plugged
into the touch panel. Two files will be created, DATA.csv
and MODE.csv. The data will be saved on the flashdrive
by default but there is also the option of using a micro SD
card. Whichever of these storage devices are used, they
must be in FAT or FAT32 format. It is recommended to
use a 2G or less storage device in order to limit the size
of the files so they can be easily opened and reviewed.
It is recommended to either download and/or delete the
files from the storage device after 8 months. The data
will stop writing to the file once the memory device is full
(notification will not be given prior to data writing stopping).
The DATA file is recorded every minute and contains the
status of the float switch, liquid make-up level sensor, low
liquid level sensor, liquid temperature, plate temperature,
shell temperature, low side pressure sensor, high side
pressure sensor, water concentration sensor, and the
state of the solenoids on the APPT. Each line will also
have a date and time stamp as well as indicating if there
is any error code at that time.
The MODE file is recorded every two minutes and it contains
the mode the purger is in at that time. The conditions
recorded are Satisfied (normal operation, collection air/
water), Cool Down, A_OP, and Water Concentration.
The data acquisition feature can be disabled if the user
so desires. Going to Menu Screen 3 and selecting Data
Acquisition, you come to the button to enable/disable
the data collection feature. Pressing DAQ ENABLED will
change the button to read DAQ DISABLED which turns
off the data collection.
DATAACQUISITION
Note: Selecting DAQ Enabled will stop the APPT from collecting
and saving the data to your storage device. To remove the storage
device, press the Remove Storage Device button. When the dot
turns green, remove your flashdrive/SD card. The touchscreen
will not record or store any data while the dot is green or when
the top button reads DAQ Disabled.
Note: When looking at the back of the Touchscreen, the USB
port is at the top left and the SD Card port is at the bottom right.
If there is both a USB and SD card installed in the Touchscreen,
only the USB will record data.
