Operational Theory

2.1Introduction

The Model 3010MB Oxygen Analyzer Control Unit uses an 80C31 microcontroller with 32 kB of RAM and 128 kB of ROM to control all signal processing, input/output, and display functions for the Model 3010MB analyzer. (The sample system and Paramagnetic sensor are covered in Part II, Analysis Unit, in this manual.) System power is supplied from a universal power supply module designed to be compatible with any international power source.

2.2Electronics and Signal Processing

All of the Analyzer electronics are located on Printed Circuit Board (PCB) assemblies inside the Control Unit chassis. The PCB locations are illustrated in section 5, Maintenance.

Refer to Figure 2-1,Block Diagram of the 3010MB CU Electronics:

In the presence of oxygen, the sensor (in the Analysis Unit) generates a current. A current to voltage amplifier (in the Control Unit) converts this current to a voltage.

The second stage amplifier amplifies the voltage. The output from the second stage amplifier is sent to an 18-bit analog to digital converter con- trolled by the microprocessor.

The digital concentration signal—along with input from the control panel—is processed by the microprocessor, and appropriate control signals are directed to the display, alarms and communications port as well as to the gas control valves in the Analysis Unit.

The same digital information is also sent to a 12 bit digital to analog converter that produces the 4-20 mA dc and the 0-1 V dc analog concentra- tion signal outputs, and the analog range ID outputs.

The microprocessor monitors the power supply, and activates the system failure alarm if a malfunction is detected.
