The menu status lines, which are the lines below the time and date, show the following information:
S/R RATIO - Signal and reference Ratio
S - Actual reading of signal intensity
R - Actual reading of reference intensity
The intensity and ratio readings for Nitrogen only update when system is running and when the detectors in
the Dual Cell Photometer are used. Any settings carried out by the user in this menu are automatically reset
when the user exits the menu.
1. Liquid Phase Components
2. Xenon Lamp. Use this function to activated/deactivate the Xenon light source. To change the state of the
device, press the ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is
on, it will be marked with an “*”.
3. NP Sample Valve. Use this function to test the NP Sample Valve. To change the state of the device,
press the ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it
will be marked with an “*”.
10. DI Water Valve. Use this function to test the DI Water Valve. To change the state of the device, press the
ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it will be
marked with an “*”.
11. TN Cleaning Valve. Use this function to test the TN Cleaning Valve. To change the state of the device,
press the ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it
will be marked with an “*”.
12. N Pump. Use this function to test the Nitrogen Pump. The pump has two operation modes: P-FWR (pulse
control forward) and P-REV (pulse control reverse). Select the required operation mode, press the
ENTER key, enter a number of pulses (½ revolutions of pump roller) to be tested, press the ENTER key
again and the pump will run the number of programmed pulses in the selected mode.
18. DCP Leak Detector. The Dual Cell Photometer (DCP) Liquid Leak Detector (if installed) is an input only
and therefore its state can not be changed from this menu. This function only indicates the state of the
DCP Leak Detector alarm input. In other words, when there is a liquid leak inside the Dual Cell
Photometer module, or during the testing of the leak detector, the system changes the state of the device
as ON, which is the leak and the fault condition or OFF, which is the default state without any leak and
fault condition.
20. Oxidation Phase Components
21. Cleaning Valve. This function can be used to test the BioTector Cleaning Valve. To change the state of
the device, press the ENTER key, set the device to ON/OFF, and press the ENTER key again. If the
device is on, it will be marked with an “*”.
22. Sample Pump. This function can be used to test the BioTector Sample Pump. The pump has four
operation modes: FWR (forward), REV (reverse), P-FWR (pulse control forward) and P-REV (pulse
control reverse). To run the pump in the required mode, press the ENTER key and select the operation
mode. When P-FWR or P-REV mode is selected, the number of pulses (½ revolutions of pump roller)
must be entered. When the pump is running, the actual pulse time (outside the brackets) and
programmed pulse time (inside the brackets) are displayed. The pump stops when the programmed
number of pulses is completed. To stop the pump manually, press the ENTER key, select OFF, and press
the ENTER key again.
24. I/O Status. I/O Status is a link to Maintenance, Diagnostics, Input/Output Status menu.
