2.2 Product overview

General information
The PHOSPHAX sc LR is a one-channel analyzer that measures ortho-phosphate ions
3—
(PO
) in waste water and surface water. The analyzer does not measure diphosphates
4
or polyphosphates. The measuring principle is based on the Vanadat-Molybdat method, also known as the Yellow method.
The analyzer is used with an SC Controller. The measured value shows on the controller display as PO4–P (default) or PO
3—
.
4
There are two analyzer models available:
• PHOSPHAX sc LR: weather-resistant enclosure for outdoor installation
• PHOSPHAX indoor sc LR: for indoor installation
The reagents and standards necessary for the chemical analysis are internally installed in the analyzer enclosure. The analyzer uses pumps, valves and syringes to move the sample and reagents to the measuring cell on the analytics panel. When the measurement cycle is complete, the analyzer discards the sample through the drain line. The analyzer can automatically do cleaning cycles and calibrations for better measurement performance. Refer to Figure 1.
The sample must be prepared and filtered before analysis. Refer to Sample requirements on page 4. Based on the system configuration, one or two analyzers can connect to a FILTRAX instrument for filtration (or an applicable sample feed) and measure one or two parameters. Refer to System configuration options on page 16.

Section 6 Troubleshooting

6.1 Troubleshoot the controller

If entries are implemented with a delay or are not accepted for a short time, the delay may be caused by a busy data network. Refer to the troubleshooting section in the controller documentation.
After a software update, a system expansion or an interruption in the power supply, it may be necessary to set the controller settings again. Record all the settings values that are changed or entered so all the necessary data can be used to configure the parameters again.
If, in usual operation, problems occur that are apparently caused by the controller, reboot the controller as follows:
1. Save all important data that is on the SC Controller.
2. Remove power from the controller. Wait 5 seconds.
3. Supply power to the controller.
4. Make sure that all of the applicable settings are correct.
5. If the problems continue, contact technical support.

6.2 Troubleshooting the analyzer

If the analyzer operation is not correct, identify if the humidity sensor has tripped. Repair the damage, dry the humidity sensor and restart the system. If the problem continues, contact technical support.
The analyzer has a status indicator light that shows different analyzer conditions, errors and warnings. Refer to Status indicator light on page 9.
