Page 8: 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 9 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 10 Sensor Flow Control Valve The sensor flow control valve is mounted to the flowmeter circuit board above the flowmeter. The sensor flow control valve adjusts the flow rate to the detector. Turn the valve’s knob clockwise to increase the flow and counterclockwise to decrease the flow. Status LEDs Two status LEDs are above the flowmeter.

Page 20: Adjusting The Low Flow Setting
Adjusting the Low Flow Setting NOTE: Adjusting the low flow setting will cause a low flow alarm at the sample-draw detector and a fail alarm at the controller. Be sure to put the controller into its calibration program or disable external alarms before performing this test. -
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
3 months is adequate for most sample draw detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the combustible gas sensor and every 6 months for the infrared CO sensor. -
Page 23: Setting The Response Reading
Setting the Response Reading 1. Screw the regulator into the combustible gas calibration cylinder. 2. Connect the sample tubing from the demand flow regulator to the sample-draw detector’s inlet line. 3. Allow the sample-draw detector to draw sample for one minute. 4. -
