7.1.3 501Y Bypass Pump Diagnostic Procedures

The 501Y bypass pump is capable of maintaining a total bypass flow rate of ~2.2 lpm. If flow checks indicate a fall off in bypass flow, the pump may need servicing. Check the pump, inlet fittings, and analyzer for leaks first. If other causes have been eliminated, rebuild the pump.

7.1.4 Electrical Fault Isolation

115 VAC is supplied to:

the bypass pump

the +5 volt and +24 volt switcher supplies

the input power to the converter temperature controller

Refer to Figure 7 to check the 115 VAC supply voltage to each of these components.

The converter temperature is controlled by the FUJI controller located on the 501Y front panel. The controller cycles power to the external converter, thereby maintaining the temperature at 315 OC, using the solid state relay.

7.2 Setting the Converter Temperature

A front panel-mounted programmable controller maintains the temperature of the remote external Converter. By pressing the PV/SV button in the lower left corner of the controller, you can see the Present Value (actual temperature) or the Set Value (temperature set point). The temperature and PID (proportional, integral and derivative) control parameters have been set at the factory and no further adjustment should be necessary. Should you need to adjust the temperature, follow these steps:

1.Select SV with the PV/SV button.

2.Press the "up-arrow" under the digit you want to change (the digit will flash),

3.Press the "up-arrow" under the digit or the "down-arrow" at the left to scroll the digit to the desired value.

4.Repeat for the other two digits.

5.Press the ENTER button.

6.Select PV with the PV/SV button to observe the actual temperature.

7.2.1Temperature Controller Setup

The FUJI temperature controller has been programmed at the factory and should not need to be altered under normal usage.

T200U-NOy specifications

The Teledyne T200U-NOy is an advanced gas analyzer specifically designed to measure nitrogen oxides (NOx) concentrations in a variety of applications, including industrial emissions monitoring, environmental assessments, and combustion control. It builds upon Teledyne's legacy of producing high-quality analytical instruments, making it a reliable choice for professionals in the field.

One of the main features of the T200U-NOy is its ability to measure multiple nitrogen oxides, including nitrogen dioxide (NO2), nitric oxide (NO), and nitrous oxide (N2O), which are critical for understanding and managing air quality and combustion efficiency. The instrument offers high sensitivity and accuracy, allowing for real-time monitoring of NOx levels with a detection limit that suits stringent regulatory requirements.

The T200U-NOy utilizes advanced chemiluminescence technology for NO measurement, which is widely recognized for its reliability and precision. This method involves the reaction of NO with ozone (O3) to produce excited NO2, which subsequently releases light as it returns to a lower energy state. The intensity of this light is measured and directly correlates to the concentration of NO in the sample, providing highly accurate readings.

In addition to its core measurement capabilities, the T200U-NOy is equipped with a variety of features that enhance its functionality. Its user-friendly interface allows for easy configuration and data retrieval, making it accessible to a wide range of users, from seasoned professionals to those new to gas analysis. The device supports multiple communication protocols, including analog and digital outputs, facilitating integration into existing monitoring systems.

The T200U-NOy is constructed with robust materials designed to withstand harsh industrial environments, ensuring longevity and reliability. It also includes features for easy maintenance, such as user-replaceable parts, which can significantly reduce downtime.

Overall, the Teledyne T200U-NOy stands out in the field of gas analyzers, combining cutting-edge measurement technologies with user-centric features and robust construction. Its comprehensive capabilities make it an essential tool for accurately monitoring nitrogen oxides, ultimately contributing to better environmental protection and compliance with air quality regulations.
