319R Introduction 1.0 Introduction The Teledyne Brown Engineering Analytical Instruments (TBE) Model 319R Oxygen Detector measures the percent of oxygen in a wide range of gases and gas mixtures. Modular and compact design provide outstanding performance and reliable on-line monitoring and make the 319R virtually maintenance-free. A special range on the 319R enables you to calibrate in ambient air. The Micro-Fuel Cell produces an output that corresponds linearly to the oxygen concentration; the

1.0 Introduction 319R 4. Proven Sensor. The 319R uses the Class Z-2 Micro-Fuel Cell, warranted for 6 months, with a life expectancy of 6 months. 5. Analog Voltage Output. The Model 319R provides customer connections to external devices, such as computers, recorders, alarms, etc., at 0–10 VDC, negative ground, plus contact closures for range identifica- tion. Custom voltage outputs, either grounded or isolated, are available as options. 6. Analog Current Output. The Model 319R has a 4–20 mA curre

319R Installation & Operation 2.0 Installation & Operation Precautions 1. Read this chapter in its entirety before installing the unit. 2. Upon receipt of the instrument, inspect the entire unit for damage. Notify the shipper if any damage is found. Check the unit, probe, and included accessories for broken or loose parts. 3. The sample must be free of entrained solids and water. A high humidity sample is ideal since it will prevent water loss from the cell electrolyte. 4. The Micro-Fuel Cell s

2.0 Installation & Operation 319R The analysis unit should be installed in the process at a maximum distance of 6 feet away from the main unit, depending upon the level of electromagnetic noise in the operating environment. Analysis Unit Connection The receptacle for the analysis unit cable is located in the lower left- hand corner of the rear panel. The 6-pin Minifit fitting is keyed to fit only one way in the receptacle; do not force it in. The other end of the cable is made of four separate

319R Installation & Operation 2.0 Alarm Terminal Connection SPDT relay contacts are provided for each of the 3 alarms. There are 9 terminals available on the back panel of the system for alarm circuit connection. The explanation for the relay terminals abbreviations is as follows: NC= Normally closed C = Common NO= Normally open The alarm relay circuits are designed for failsafe operation, meaning that the relays are activated (energized) during normal operation. If power fails, or if an alarm

2.0 Installation & Operation 319R Setting Alarms The alarms can be adjusted over the full scale range, and they are set as a percent of full scale. Thus, an alarm set to indicate 192 on the display while on the 200 PPM O range will activate at 192 PPM O on the 200 2 2 PPM O range and at 1920 O on the 2000 O range (96% of full scale). To 2 2 2 set the alarms: 1. Place the range switch located below the front panel display in the 2000 PPM range position (or highest range available). 2. Place the

319R Installation & Operation 2.0 Calibration To calibrate the 319R: 1. Place the power switch in the ON position. 2. Allow the LCD reading to stabilize. 3. Expose the sensor to ambient air (20.9%) or instrument grade air. If the analyzer goes overrange, the display will go blank and the LED to the left of the display will blink. Hold down the SPAN button until the LED stops blinking. 4. While holding down the SPAN AT 20.9% button, adjust the potentiometer to the right of the button until the d

319R Maintenance 3.0 Maintenance Replacing the Fuse If the unit will not turn on when plugged in and switched ON (via the power switch), or you suspect a blown fuse, replace the fuse using the following procedure: 1. Disconnect the AC power and place the power switch located on the rear panel in the OFF position. 2. The fuse is located next to the power cord receptacle in the upper left-hand corner of the rear panel. Remove the power cord from the receptacle. 3. Insert a small flat-blade screwd

3.0 Maintenance 319R 5. Replace the fuse holder into its receptacle, pushing in firmly until it clicks. In units with DC power, the fuse is located on the rear panel above the ON/OFF switch. Open the fuse holder by unscrewing and removing the knob marked FUSE. The fuse will be located inside the knob. Replacing the Sensor The characteristics of the Micro-Fuel Cell are similar to those of a mercury battery in that both provide an almost constant output through their useful life, and then fall of

319R Maintenance 3.0 Warranty Conditions The Class Z-2 cell used in the 319R is warranted for six (6) months of service from the date of shipment. Customers having warranty claims must return the cell in question to the factory for evaluation. If it is determined that failure is due to faulty material or workmanship, the cell will be replaced free of charge. CAUTION: Evidence of tampering or abuse will render the warranty null and void.
