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.

 

DATA ACQUISITION 

 

The APPT features a data collec>on which is ac>vated by default on start up of the APPT, unless the user manually 
deac>vates 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 op>on 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 4G 
or less storage device in order to limit the size of the files so they can be easily opened and reviewed. 

 

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 concentra>on sensor, and the state of the solenoids on the APPT. Each line will also have a 
date and >me stamp as well as indica>ng if there is any error code at that >me. 

 

The MODE file is recorded every two minutes and it contains the mode the purger is in at that >me. The condi>ons 
recorded are Sa>sified (normal opera>on, collec>on air/water), Cool Down, A_OP, and Water Concentra>on.  

 

The data acquisi>on feature can be disabled if the user so desires. Going to Menu Screen 3 and selec>ng Data 
Acquisi>on, you come to the screen below.

Selec>ng DAQ Enabled will stop the APPT from collec>ng and saving the data to your storage device. To remove the 
storage device, press the Remove Storage Device buPon. 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 buPon reads DAQ 
Disabled.  

 

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.

will stop wri1ng to the file once the memory device is 
full (no1fica1on will not be given prior to data wri1ng 
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 
concentra1on sensor, and the state of the solenoids 
on the APPT. Each line will also have a date and 1me 
stamp as well as indica1ng if there is any error code 
at that 1me. 

The MODE file is recorded every two minutes and it 
contains the mode the purger is in at that 1me. The 
condi1ons recorded are Sa1sified (normal opera1on,
