USING THE SYSTEM
23
Connection to PC
To transfer log information from the system to PC you need:
1 – RS232-USB adapter;
2 – Install RS232 drivers on the PC that will be used for data collection;
3 – Download from Internet freeware program “RealTerm: Serial/TCP Terminal”;
4 – Install the program;
5 – Open program & set “Port” settings:
- Baud: 19200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Hardware flow control: None
6 – Choose the right port and press “Open”. Data will be sent every 5 minutes.
7 – The log of water quality and errors is stored inside the microcontroller as well.
8 – To obtain the saved log go to:
MenuSensorsSend log to PC
The log is rewritten after it is sent to PC.
9 – To save data in file:
- Press Capture;
- Choose directory where you want to save the file;
- Press: “Start Append” or “Start Underwrite”;
- Files will be saved in your file directory and data will be sent every 5 minutes to this file;
- To obtain the saved log, you can go to:
MenuSensorsSend log to PC
- The log is rewritten after it is sent to PC.
Rinsing the system
Press “Run” button to start operation. Leave the system running for 2 hours. Check through the front
door that the connectors were not loosened during the transportation and that there are no water
leaks.
Check water flows in OUT and Drain pipes. The water flow in the Drain pipe should be 2-5 times higher
than in the OUT pipe. If the water flow in the OUT pipe is higher than in Drain, the RO membrane is
damaged.
The microfilter (or ultrafilter) should be rinsed prior to use! When the tank is full, press the “Dispense”
button and rinse the microfilter (or ultrafilter) with at least 10 liters (or 20 liters respectively) of purified
water.
Allow the Q-Front system to fill the tank, shut off feed water supply and leave the system in operation
overnight to allow it to recirculate water in the tank, remove all the residual organic contamination and
reduce TOC reading to <2 ppb (for HPLC and Bio configurations).
