Page 7: External Components
External Components This section describes the sample-draw detector’s external components. Housing The sample-draw detector’s fiberglass housing is weather- and corrosion-resistant. It is suitable for installation where general purpose equipment is in use. The housing door is hinged on the left side and is secured by two latches on the right side. The flowmeter and status LEDs are visible through a window in the housing door. - Page 8 Main Circuit Board The main circuit board includes the detector/amp terminal strip, interconnect terminal strip, oxygen sensor terminal strip, pump connector, and flowmeter circuit board connector (see Figure 1). Detector/Amp Terminal Strip The detector/amp terminal strip is the upper twelve-point terminal strip in the bottom right corner of the main circuit board.
- Page 9 Status LEDs Two status LEDs are above the flowmeter. They are also visible through the window in the housing door. The green Pilot LED is on when the sample-draw detector is receiving power from the controller. The red Fail LED is on when the sample flow rate is below the low flow level. Pressure Switch The pressure switch is mounted to the back of the flowmeter circuit board.
- Page 10 Amplifier The amplifier converts the electrical output from the sensor to a 4 to 20 mA signal that corresponds to the detection range and transmits the signal to a gas monitoring controller. A label on the amplifier indicates the detector drive current. This drive current is factory set. The amplifier is mounted on the top middle edge of the main circuit board.

Installation This section describes procedures to mount the sample-draw detector in the monitoring environment and wire the sample-draw detector to a controller. Mounting the Carbon Dioxide Sample-Draw Detector Select the mounting site. Consider the following when you select the mounting site: •... -
Page 12: Connecting The Sample Lines To The Sample-Draw Detector
Connect a length of sample tubing to the other side of the particle filter and route it to the sampling area. 1/4” O.D. rigid polypropylene, Teflon, or flexible polyurethane tubing may be used. RKI Instruments, Inc. recommends using either 1/4” O.D. x 1/8” I.D. or 1/4” O.D. x 0.170” I.D. tubing based on your length requirements. -
Page 13: Wiring The Carbon Dioxide Sample-Draw Detector To A Controller
Push 1/4” O.D. rigid polypropylene or rigid Teflon sample tubing into the fitting until it stops. Flexible polyurethane tubing may be used with an appropriate insert. RKI Instruments, Inc. recommends using either 1/4” O.D. x 1/8” I.D. or 1/4” O.D. x 0.170” I.D. tubing based on your length requirements. See “Specifications”... - Page 14 Connect the wires to the applicable detector/transmitter terminal strip at the controller as shown in Figure 5. Refer to the controller operator’s manual and the controller detector head specification sheet for the 35-3001A-05-XX for detector/terminal strip connections specific to the controller.

Page 15: Start Up
Start Up This section describes procedures to start up the sample-draw detector and place the sample-draw detector into normal operation. Introducing Incoming Power Complete the installation procedures described earlier in this manual. Verify that the wiring is correct and secure. Refer to the controller operator’s manual for connections at the controller. -
Page 16: Setting The Zero Reading
Setting the Zero Reading Since there is a background of CO in air of typically 300 - 600 ppm (0.03 - 0.06% volume), it is necessary to use a calibration kit with a 100% nitrogen cylinder to set the zero signal for the 0 - 5,000 ppm and 0 - 5% volume versions. -

Page 18: Replacing Components Of The Carbon Dioxide Sample-Draw Detector
If the calibration/response difficulties continue, contact RKI Instruments, Inc. for further instruction. Replacing Components of the Carbon Dioxide Sample-Draw Detector This section includes procedures to replace the sensor, hydrophobic filter, and particle filter. Replacing the Infrared Carbon Dioxide Sensor Turn off the controller. - Page 19 Install the detector and controller plug-in terminals strips into their sockets on the new amplifier. If controller leads or detector cable leads were removed from the plug-in terminal strips during this procedure, refer to Table 2 and Table 3 below.

Page 20: Adjusting The Low Flow Setting
Replacing the Particle Filter Turn off the controller. Turn off power to the controller. If the particle filter is installed at the inlet fitting: Disconnect the tubing routed to the sampling area, if installed, from the particle filter. Disconnect the particle filter from the tubing stub. Install the new particle filter onto the tubing stub. -
Page 21: Removing The Particle Filter's Tubing Stub, If Necessary
Removing the Particle Filter’s Tubing Stub, if Necessary A short tubing stub comes factory installed in the particle filter. It is used for connecting the particle filter to the inlet fitting. If you have installed the particle filter and no longer want it installed, you will need to remove the particle filter’s tubing stub from the inlet fitting and replace it with tubing. -
Page 22: Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 6 months is adequate for most infrared carbon dioxide sample draw applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 6 months. -
Page 23: Setting The Response Reading
Unscrew the regulator from the 100% nitrogen calibration cylinder. Setting the Response Reading Screw the regulator into the carbon dioxide calibration cylinder. Connect the sample tubing from the demand flow regulator to the sample-draw detector’s inlet line. Allow the sample-draw detector to draw sample for one minute. When the reading on the voltmeter stabilizes, verify that the reading matches the response reading (±2 mV) you determined earlier. -
